Description
Technical Field
The utility model relates to the technical field of medical instruments, in particular to a disposable pleuroperitoneal cavity puncture indwelling catheter.
Background
The pleural and peritoneal effusion of the patient is caused by the tumor or inflammatory changes. A small amount of pleural effusion does not need to be treated immediately, and once a large amount of effusion appears, the pleural puncture or puncture catheter drainage is needed to relieve a series of symptoms caused by the fact that the effusion presses the internal organs in the lung or abdominal cavity. Some patients need to keep a catheter for a long time and drain the effusion discontinuously due to the unsatisfactory control of the primary disease or the excessive growth of the effusion. For example, when the muscles of the chest wall or the abdominal wall of a patient are weak, the mobility of the catheter is high, or the pressure of the liquid is high, the phenomenon that the accumulated liquid in the abdominal cavity seeps outwards along the catheter wall can occur. Because of tumor cells and the like in the effusion, the effusion extravasation can cause the phenomena of local tumor implantation metastasis, secondary infection and the like, aggravate the pain of patients, increase the treatment difficulty and increase the workload of medical care personnel. At present, catheter seepage is clinically treated by local dressing change and proper pressure dressing, and a few seepage can be reduced or stopped. However, for patients with large sinus, weak muscle at the tube placing part, and more accumulated liquid or faster growth, the effect is not ideal, and most of the patients need to pull out the liquid seepage catheter and additionally place a new catheter, thereby increasing the pain and medical expense of the patients.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing a disposable pleuroperitoneal cavity puncture indwelling catheter.
In order to solve the technical problems, the technical scheme of the utility model is as follows:
the disposable pleuroperitoneal cavity puncture indwelling catheter comprises a built-in drainage tube, wherein a water sac is arranged in the middle section of the built-in drainage tube, the water sac is fixed on the periphery of the tube wall of the middle section of the built-in drainage tube in a semi-encircling manner to form a water sac area with the middle section of the built-in drainage tube, a single tube is connected to the tail end of the water sac, the tail end of the single tube is a water sac interface, and the tail end of the built-in drainage tube is a drainage tube interface.
Preferably, the end of the built-in drainage tube of the disposable pleuroperitoneal cavity puncture indwelling catheter is provided with an external fixator.
Preferably, the disposable pleuroperitoneal cavity puncture indwelling catheter further comprises an external drainage tube, the external drainage tube is communicated with the internal drainage tube through a drainage tube interface, the tail end of the external drainage tube is connected with a drainage bag, and a catheter switch clamp is arranged on the external drainage tube.
Preferably, the drainage bag of the disposable pleuroperitoneal cavity puncture indwelling catheter is provided with volume scales.
Preferably, the disposable pleuroperitoneal cavity puncture indwelling catheter is made of polyurethane.
Preferably, the disposable pleuroperitoneal cavity puncture indwelling catheter is characterized in that the water sac is made of latex.
Has the advantages that:
after the disposable pleuroperitoneal cavity puncture indwelling catheter is successfully punctured and placed in an abdominal cavity or a thoracic cavity, the indwelling drainage tube is indwelling, sterile normal saline is injected into the water sac through the water sac interface, the catheter is more tightly fixed on a chest wall, an abdominal wall or a puncture needle channel through the water sac, liquid is prevented from leaking outside through the thoracic cavity or the abdominal cavity wall, and an exposed part is fixed on the surface of skin through the fixing clamp. When the hydrops is drained, the external drainage tube and the drainage bag are connected to the drainage tube connector, the catheter switch clamp is loosened, the phenomenon of liquid extravasation in the pleuroperitoneal cavity can be effectively reduced or avoided after the pleuroperitoneal cavity is punctured, the risk of transfer or secondary abdominal infection caused by the fact that the hydrops extravasate secondary tumor is planted along a needle channel is avoided, the life quality of a patient is improved, the waste of medical resources is avoided, and the medical safety and the satisfaction degree of the patient are guaranteed.
