Technical Field

The invention relates to the technical field of medical consumables, in particular to a disposable double-cavity pleuroperitoneal cavity catheter.

Background

The pleural effusion and the peritoneal effusion are the problems commonly existing in malignant tumor patients, the closed thoracic drainage is performed by utilizing a double-cavity central venous catheter in the current clinical treatment, the pain and the damage to the patients caused by repeated puncture are avoided by the treatment scheme, and the complications such as local adhesion, thick pleura and the like caused by incomplete discharge of body fluid can be avoided; the double-cavity central venous catheter is soft, has small irritation to pleura and peritoneum, and can move freely during catheterization.

In addition, the administration in the thoracic cavity and abdominal cavity can be carried out through an indwelling catheter, such as injection of chemotherapeutic drugs, antibiotics and the like. However, because the double-lumen venous catheter has a thin tube diameter, the thoracic fluid or the abdominal fluid is sticky or precipitates, which easily causes poor drainage or blockage. Too fast a drainage rate can cause a pleural reaction. The existing double-lumen catheters are fixed on the skin surface of a patient in a pressing way by matching with a slide fastener, and the slide fastener and the double-lumen catheter are mainly fixed by the mutual friction force generated between the slide fastener and the double-lumen catheter so as to achieve the purpose of fixation. Due to the fact that the wall of the double-cavity catheter is smooth, when liquid leakage occurs, sliding between the sliding buckle and the double-cavity catheter is easy to occur, and the phenomenon of pipe falling is caused, so that certain potential safety hazards exist.

Disclosure of Invention

The invention aims to provide a disposable double-cavity thoracic and abdominal cavity catheter which can realize better fixation on a double-cavity catheter so as to reduce potential safety hazards.

The technical purpose of the invention is realized by the following technical scheme: the utility model provides a disposable two-chamber pleuroperitoneal cavity pipe, includes two-chamber pipe, the intercommunication has main chamber extension pipe and side chamber extension pipe on the two-chamber pipe, be equipped with the pipe on the two-chamber pipe and detain, the pipe is detained and is equipped with the through-hole that supplies two-chamber pipe to pass, be equipped with the one-way component that restriction two-chamber pipe removed along its axial towards main chamber extension pipe one side between two-chamber pipe and the pipe is detained.

Through adopting above-mentioned technical scheme, detain the pipe and fix in patient's skin surface, the effect restriction double-chamber pipe through one-way component removes towards one side at main cavity extension pipe place to reach the function of stopping, prevent that the two-chamber pipe of male from deviating from, realize better fixing to the double-chamber pipe, reduce the potential safety hazard of existence. And the function of the one-way component enables the double-cavity catheter to move back to one side of the extension tube of the main cavity, so that the insertion depth of the double-cavity catheter can be adjusted, and the operation of medical staff is facilitated.

Further setting the following steps: the one-way component comprises a one-way rack arranged on the peripheral wall of the double-cavity catheter and a first tooth block arranged on the catheter buckle and meshed with the one-way rack.

Through adopting above-mentioned technical scheme, the cooperation between first tooth piece and the one-way rack makes two-chamber pipe can slide along one side direction to reach the function of stopping.

Further setting the following steps: one-way rack includes that the second gear block that sets up by a plurality of interval arrangements constitutes, the second gear block is the second perpendicular of perpendicular to two-chamber pipe axis towards one side of main cavity extension pipe, the second guide inclined plane that one side of main cavity extension pipe is set up for the slope is backed to the second gear block, one side of main cavity extension pipe is backed to first two-chamber perpendicular of perpendicular to pipe axis for first tooth block, the first guide inclined plane that one side of first tooth block orientation main cavity extension pipe set up for the slope.

Through adopting above-mentioned technical scheme, when first guide inclined plane moved towards second guide inclined plane, through the effect direction of inclined plane change power for first tooth piece can move towards second guide inclined plane one side, realizes unidirectional movement. When the first vertical surface moves towards the second vertical surface, the two vertical surfaces are mutually abutted, so that the first tooth block cannot move towards one side of the second vertical surface, and the limiting is realized.

Further setting the following steps: the catheter buckle is provided with a fixing hole.

Through adopting above-mentioned technical scheme, the setting of fixed orifices can be detained the direct suture in skin and be fixed with the pipe to detain and realize better fixed in patient's on one's body the pipe.

Further setting the following steps: the catheter buckle is provided with an adhesive tape.

Through adopting above-mentioned technical scheme, according to patient's different situation, can adopt to sew up fixedly or paste the sticky tape bonding and fix, adopt to paste the sticky tape bonding fixed mode and can realize more simple and convenient dismantlement to make this pipe have better practicality at the in-process of in-service use.

Further setting the following steps: the wing-shaped joint comprises a wing-shaped joint with an inner cavity, one end of the double-cavity catheter is communicated with the inner cavity of the wing-shaped joint, one end of the main cavity extension tube is communicated with the inner cavity of the wing-shaped joint, and one end of the side cavity extension tube is communicated with the inner cavity of the wing-shaped joint.

Through adopting above-mentioned technical scheme, the setting up of wing section joint realizes better switching on between two-chamber pipe, main cavity epitaxial tube, the lateral cavity epitaxial tube three, reduces the emergence of jam probability.

Further setting the following steps: and a flow rate regulator is arranged on the extension pipe of the main cavity.

Through adopting above-mentioned technical scheme, the setting control liquid velocity of flow regulator reduces the discomfort that causes the patient.

Further setting the following steps: the free ends of the main cavity extension pipe and the side cavity extension pipe are both provided with threaded joints, and the threaded joints are in threaded connection with heparin caps.

Through adopting above-mentioned technical scheme, medical personnel's operation is made things convenient for in the setting of heparin cap, improves work efficiency, reduces the medical expense.

In conclusion, the invention has the following beneficial effects: the double-cavity catheter fixing device can realize better fixation of the double-cavity catheter, so that potential safety hazards are reduced.
