Technical Field

The invention relates to the technical field of infusion bags, in particular to a weak welding spot type infusion bag with a pressure relief function.

Background

In recent years, more and more attention is paid to nutrition infusion in clinical application, and particularly, patients with critical diseases or patients after surgical treatment need to be supplemented with nutrition in time to be well recovered; the existing nutritional infusion products mainly comprise glucose, amino acid, fat emulsion and the like, and the packaging mode mainly comprises the following steps: single-bag glass bottles and single-bag soft bag products, wherein the glass bottles are mainly used; the nutrition required by the human body can meet the requirements of the human body not only by a single product but also by the mutual matching of a plurality of nutrient substances.

Disclosure of Invention

The invention aims to provide a weak welding point type infusion bag with a pressure relief function, and aims to solve the technical problems in the background technology.

In order to achieve the purpose, the invention adopts the following technical scheme:

a weak welding spot type infusion bag with a pressure relief function comprises a bag body, wherein an accommodating cavity is arranged in the bag body; the weak welding rods are arranged on the bag body, the containing cavity is divided into a plurality of cavities for containing liquid or powder, and the adjacent cavities are separated by two weak welding rods; the two weak welding rods are arranged in parallel, a buffer cavity is arranged between the two weak welding rods, and the accommodating cavity is internally vacuumized; the weak welding points are arranged on the bag body in the buffer cavity; the number of the mouth pipes corresponds to that of the chambers one by one, the mouth pipes are arranged on the bag body, and the mouth pipes are communicated with the chambers one by one; the number of the easy-to-fold covers is in one-to-one correspondence with the number of the mouth tubes, and the easy-to-fold covers are in one-to-one correspondence and are hermetically connected to the mouth tubes; the mouth tube and the easy-to-break cover are integrally formed; the tail filling part is arranged on the side wall of the bag body opposite to the mouth pipe, the tail filling part is communicated with the cavity before filling, and after filling, the two side walls of the bag body of the tail filling part are welded and sealed.

Furthermore, weak welding point is the easy isolation point that tears that forms through the welding between two lateral walls of the bag body, the welding power that easily tears between isolation point and the bag body is less than the pulling force that receives when pulling open two lateral walls of the bag body to opposite direction. The setting of weak solder joint is in order to play the effect of buffering, and when the weak welding rod of one side opened under the non-user state because the high altitude falls, striking etc. promptly under unexpected condition, liquid or powder in the weak welding rod of opening one side can be gushed into in the buffering cavity, and then play the effect of pressure release, reduce the influence that the pressure that weak welding rod opened one side to the weak welding rod of opposite side promptly as far as possible, prevent that the weak welding rod of both sides all is opened under the non-user state. The weak welding points are arranged in the buffer cavity, so that the effect of first pressure relief is achieved, namely when the buffer cavity is opened in a non-use state, liquid or powder in the weak welding rods on one side of the opening side gushes into the buffer cavity, the weak welding points are spread to consume a part of energy, further the release of part of accidental pressure is completed, and the influence of the weak welding rods on the other side is reduced as much as possible.

Further, weak welding rod is the easy division bar that tears that forms through the welding between two lateral walls of the bag body, easily tear the welding power between division bar and the bag body and be less than with the bag body along the length direction who easily tears the division bar when curling and pressing, easily tear the pressure that receives between division bar and the bag body.

Furthermore, the welding patterns of the easy-to-tear isolating strips are a plurality of diamond-shaped welding patterns. The rhombic welding lines can not only completely seal liquid between the chambers, but also buffer the impact force between the chambers and resist falling, particularly the impact force in the transportation process. The rhombus welding lines further improve the sealing quality between the chambers, reduce the extrusion deformation between the film materials and improve the attractiveness of the bag body to the maximum extent.

Furthermore, the tail irrigation part is provided with a hanging hole.

Furthermore, a first hand-held hole is formed in the bag body on two sides of the tail irrigation part.

Furthermore, a bag head body is arranged on one side of the bag body, which is provided with the mouth pipe, a plurality of second hand-held holes are formed in the bag head body, and the second hand-held holes are distributed in the bag head bodies on the two sides of the mouth pipe.

Furthermore, the periphery of the bag body is provided with a leakage-proof isolation layer.

Furthermore, four vertex angles of the bag body are provided with fillets.

Furthermore, a bag tail body is arranged on one side, opposite to the opening pipe, of the bag body, and a hanging hole is formed in the bag tail body.

Furthermore, a plurality of first handheld holes are formed in the bag tail body, and the first handheld holes are distributed on two sides of the hanging hole. Set up first handheld hole, can bring better operation experience for the operator. Is convenient for taking and placing. When taking and placing the infusion bag, the cavity can not be directly held by hands, so that the frequency of extruding weak welding rods between the cavity and the cavity when the infusion bag is not opened is reduced, and the abnormal opening probability is reduced.

Further, the bag tail body is arc-shaped on one side opposite to the opening pipe. The arc bag tail body can be convenient for when opening, curls the bag tail body and extrudes two weak welding rods, the weak welding rod of being convenient for open smoothly.

Furthermore, a bag head body is arranged on one side of the bag body, which is provided with the mouth pipe, a plurality of second hand-held holes are formed in the bag head body, and the second hand-held holes are distributed in the bag head bodies on the two sides of the mouth pipe. Set up the handheld hole of second, can bring better operation experience for the operator. Is convenient for taking and placing. When taking and placing the infusion bag, the cavity can not be directly held by hands, so that the frequency of extruding weak welding rods between the cavity and the cavity when the infusion bag is not opened is reduced, and the abnormal opening probability is reduced.

Furthermore, the periphery of the bag body is provided with a leakage-proof isolation layer. The leak protection isolation layer can decorate the bag body pleasing to the eye, also can carry out the secondary protection to the leak protection of the bag body simultaneously, further improvement bag body quality.

Furthermore, four vertex angles of the bag body are provided with fillets. The fillet can play the guard action to the bag body after filling, can reduce to answer liquid or powder impact force too big, causes the welding department damaged, furthest's promotion product quality, and the aesthetic feeling of more powerful.

Compared with the prior art, the invention has the beneficial effects that:

1. the invention has novel structure and strong practicability. The bag body is provided with the two weak welding rods, so that a double-insurance effect is achieved, and even if a single weak welding rod is opened under an abnormal condition, the liquid or powder contained in the two cavities cannot be mixed when the two cavities are used abnormally. Greatly improves the safety of medication. The infusion bag with the weak welding rod is convenient to open.

2. By arranging the buffer cavity and the weak welding points, the probability that the infusion bag is opened under unexpected conditions (such as transportation bump, high-altitude falling, impact and the like) can be further reduced.

3. The infusion bag provided by the invention is filled in a tail filling mode, so that the situation that welding scraps fall into the cavity is avoided.
