Technical Field

The invention relates to the technical field of medical instruments, in particular to a non-outflow covering type hemostatic bandage.

Background

The existing hemostasis carries out first aid on the big bleeding of limbs by compressing blood vessels to block blood circulation. However, if the tourniquet is improperly used or used for a long time, the tourniquet can cause ischemia and necrosis of the distal limb, which results in disability. Moreover, the tourniquet can not be used on the lower leg and the forearm, and the tourniquet can not press the blood vessel because the two bones are arranged at the position and the blood vessel is just between the two bones. The tourniquet cannot be used at the middle 1/3 of the upper arm, which may cause nerve damage and arm paralysis. The primary tourniquet is generally made of natural rubber and is wide and flat. Independent single packing is many, and the nursing staff uses very inconveniently, must disassemble packing, the use of high frequency before using at every turn and leads to work efficiency greatly reduced.

Therefore, the invention researches a non-outflow covered hemostatic bandage for treating the heavy bleeding of the upper arm, the forearm, the thigh and the lower leg. The tourniquet is simple and quick in hemostasis operation, free of a plurality of limits and risks of tourniquets, and has great medical reality significance.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, the present invention provides a technical solution: a covering non-outflow type hemostatic bandage comprises a plastic non-blood-sucking bandage 1, wherein an extrusion hemostatic assembly 2 is installed on the plastic non-blood-sucking bandage 1, and an elasticity adjusting assembly 3 is installed on the plastic non-blood-sucking bandage 2.

Specifically, the plastic non-blood-sucking bandage 1 comprises a bandage main body 11, wherein first strong adhesive layers 12 are adhered to two ends of the bandage main body 11, an extension area 13 is integrally formed on the bandage main body 11, and a blood seepage scale line 14 is marked on the extension area 13.

The oozing graduation lines 14 are used for visually observing the oozing state so that the doctor can know and process the oozing state in time.

When the non-outflow type covered hemostatic bandage 1 is not used, the sticker on the first strong adhesive layer 12 is kept complete, and the seal sticker is closed to cover the wound area completely.

The bandage main body 11 is made of a heat-sealing type biaxial tension polypropylene film material, has good permeability resistance and stretch resistance, the first strong adhesive glue layer 12 is made of ethylene-vinyl acetate copolymer, coumarone-indene resin, synthetic paraffin resin, talcum powder and 6-di-tert-butyl-p-cresol, has strong adhesive force, is stable after being bonded, and enables the bandage 1 which cannot be covered by the bandage to be not easy to loosen.

Specifically, the extrusion hemostasis assembly 2 comprises a medical wound sticker 21 and a second strong adhesive layer 22, a non-blood-suction bandage layer 23 is bonded on the lower end of the medical wound sticker 21, a silica gel outer sleeve 24 is sleeved on the outer side walls of the medical wound sticker 21 and the non-blood-suction bandage layer 23, the second strong adhesive layer 22 is bonded on the bandage main body 1, and the second strong adhesive layer 22 is located on the outer edge of the silica gel outer sleeve 24.

The second strong adhesive layer 22, the cross-shaped strong adhesive films 2-4 and the cross-shaped strong adhesive layer 2d are medical e-cyanoacrylate 6B series glue or fibrin biological glue, which is not easy to generate adverse reaction after contacting with a wound on the premise of better adhesiveness, and the blood-sucking-free bandage layer 23 is a heat-sealing type two-way stretching polypropylene film.

Specifically, the tightness adjusting assembly 3 comprises a U-shaped supporting sleeve 31, a silica gel air bag 32 is arranged on the U-shaped supporting sleeve 31, and an air valve 33 is arranged on the silica gel air bag 32.

Specifically, the air valve 33 includes an air valve nozzle 331, a valve cavity 332 is formed in the air valve nozzle 331, a sealing ball 333 is sleeved in the valve cavity 332, and a spring 334 which is extruded with the sealing ball 333 is sleeved in the valve cavity 332.

Need pay attention to when installing elasticity adjusting part 3, the locating place of elasticity adjusting part 3 needs to be relative with extrusion hemostasis subassembly 2, when avoiding silica gel gasbag 32 inflation, pulls open its strong adhesion glue film 22 bonding department of second.

The working principle is as follows: when the upper arm, the forearm, the thigh and the calf are bleedingly bleeding, the first aid is carried out, the sticker on the first strong adhesive layer 12 is taken off, the sealing sticker is torn off, and the extrusion hemostasis assembly 2 is opened. The compression hemostasis assembly 2 is pressed down towards the wound, the top of the silica gel outer side sleeve 24 is attached to the skin around the wound for a circle to close the wound, the second strong adhesive glue layer 22 is pressed by hands to be firmly adhered to the skin, the silica gel outer side sleeve 24 with a certain thickness prevents blood from flowing outwards, the blood sprayed from the wound quickly fills the silica gel outer side sleeve 24, the wound area is covered by the adhesive effect of the second strong adhesive glue layer 22 and is tightly buckled on the wound and the skin nearby, and the blood cannot further flow out.

The plastic non-blood-sucking bandage 1 is wound on the wound part for several circles, and the wound is finished by adhering the bandage main body 11 on the lower layer by using the first strong adhesive glue layer 12 at the end.

Therefore, the wound is extruded by the protruded extrusion hemostasis assembly 2, the problem that the blood cannot circulate because the limbs are completely extruded and wound by the hemostasis bandage is solved, and the wound periphery is extruded and sealed by the adhesion of the second strong adhesive glue layer 22 and the skin and the silica gel outer side sleeve 24, so that the hemostasis effect is improved.

According to the invention, through the use of the tightness adjusting component 3, the silica gel air bag 32 is contacted with the skin when the plastic non-blood-sucking bandage 1 is wound, if the plastic non-blood-sucking bandage 1 is too loose, the air valve nozzle 331 can be inserted into the silica gel air bag 32 through the injector to inflate the silica gel air bag, and if the plastic non-blood-sucking bandage 1 is too tight, the pen point or other rod-shaped objects can be used for squeezing the sealing ball 333 to release the other parts in the silica gel air bag 32, so that the tightness adjusting function is realized.
