Description

A rapid disposable peritoneal effusion puncture and drainage device

Technical Field

The utility model relates to the technical field of medical devices, in particular to a quick disposable peritoneal effusion puncture and drainage device.

Background Art

For chronic and recurrent abdominal effusion, especially malignant abdominal effusion, when the amount is large, the patient will have obvious abdominal distension and ask the doctor to extract ascites to relieve symptoms. There are currently two main methods for this: First, the traditional abdominal puncture uses a reusable or disposable abdominal puncture kit, routine disinfection, drape, anesthesia, puncture, and finally uses an empty needle to extract the effusion one tube at a time, which generally takes half an hour or even longer; the disadvantage is that it is time-consuming and labor-intensive, the patient experience is poor, and doctors are not willing to do it. Second, use a new type of abdominal catheter, routine disinfection, drape, anesthesia, puncture, and catheterization. After teaching the patient how to operate, he can drain it himself every day; the disadvantage is that it is expensive and requires maintenance in the later stage. The patient's acceptance is not very high. After a few days of use, many sequelae such as infection, catheter slippage, and incision exudation may occur. Especially after a long time of catheterization, repeated exudation will cause headaches for patients, family members, and doctors. Therefore, it is urgent to improve this situation.

Utility Model Content

In view of the technical problems that the existing peritoneal effusion puncture and extraction is time-consuming and laborious, the peritoneal catheter is expensive, the patient acceptance is low, and many sequelae such as catheter slippage and incision exudation are prone to occur after a few days of use, the utility model provides a fast disposable peritoneal effusion puncture and drainage device, which is cheap, easy to operate and not prone to exudation.

In order to solve the above technical problems, the utility model adopts the following technical solutions:

A rapid, disposable ascites puncture and drainage device comprises a drainage catheter, a puncture needle core, a drainage hose, a first connecting tube and an infusion branch tube, wherein the needle head of the puncture needle core is arranged in the drainage catheter and can be tightly penetrated from the front end of the drainage catheter, the end of the puncture needle core away from the needle head can be moved and tightly extended out of the rear end of the drainage catheter, a through hole is penetrated through the needle wall of the puncture needle core located in the drainage catheter, one end of the drainage hose is connected to the tube wall near the rear end of the drainage catheter, and the other end of the drainage hose is respectively connected to the first connecting tube and the infusion branch tube through a three-way switch, a flow rate regulator is sleeved on the first connecting tube, a first interface which can be connected to a tube cap type interface drainage bag is provided at the end of the first connecting tube, and a heparin cap is threadedly connected to the end of the infusion branch tube.

The utility model provides a quick disposable peritoneal effusion puncture and drainage device. When used, it is first routinely disinfected, and then sterile gloves are worn to hold the puncture part (drainage catheter and puncture needle core) of the device for puncture. When the peritoneal effusion is seen to flow into the drainage catheter through the through hole of the puncture needle core, it is considered that the peritoneal effusion puncture is successful. That is, the puncture needle core and the drainage catheter are used together to ensure the success of the peritoneal effusion puncture. Then, after entering a certain depth, the puncture needle core is removed, the puncture site is covered with a transparent dressing, the outer end of the drainage catheter is fixed so that it is not easy to slip off, and then it is retained in the abdominal cavity through the connection with the first interface. The tube cap type interface drainage bag is used to drain the peritoneal effusion. After the drainage is completed, the drainage catheter is removed and the puncture site is covered with a dressing. During the drainage process, the drainage speed can be adjusted by the flow rate regulator. At the same time, the heparin cap connected to the end of the infusion branch can be punctured by an infusion needle to infuse the drug solution, or the heparin cap can be removed and connected to a syringe to aspirate the effusion for inspection, which is highly practical. The three-way switch is used to control the conduction between the drainage hose and the first connecting tube or the conduction between the drainage hose and the extraction and infusion branch tube, and to prevent the drug solution from entering the first connecting tube when the drug solution is infused through the extraction and infusion branch tube. Therefore, compared with the prior art, the rapid disposable peritoneal effusion puncture and drainage device provided by the utility model has the following advantages: 1) Compared with traditional peritoneal puncture, the device not only achieves the purpose of one-time operation, but also reduces the use of consumables and costs, and avoids the trouble of using a handheld needle and extracting tube by tube, saving time and effort; 2) The device combines the puncture needle core and the drainage catheter together, and the overall diameter is small, so the puncture can be completed quickly in one time, eliminating the need for anesthesia, skin expansion, suturing and fixation operations; and during and after drainage, it is not easy to leak fluid; the trauma is small, and the site can be changed every day and the operation can be repeated; 3) The overall material of the device is small and the cost is low; 4) There are double interfaces of a tube cap type interface drainage bag and a heparin cap spiral mouth, which is highly practical.

Furthermore, the diameter of the drainage catheter is 0.9-1.2 mm and is thin at the front and thick at the back. The length from the front end of the drainage catheter to the connection between the drainage hose and the drainage catheter is 5-7 cm.

Furthermore, the rear end of the drainage catheter is sealed and connected to the silicone plug, and the end of the puncture needle core away from the needle head can be moved to tightly pass through the silicone plug and then extend out of the rear end of the drainage catheter.

Furthermore, the end of the first connecting tube is detachably connected to the second connecting tube, and the end of the second connecting tube is provided with a second interface that can be connected to a conical interface drainage bag.

Furthermore, a plug which can be plugged into the second interface is connected to the tube wall of the second connecting tube.
