Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to novel uropoiesis is bladder perfusion tube for surgery.
Background
Bladder instillation is a therapeutic and prophylactic procedure in which drugs are infused directly into the bladder via a catheter, a technique routinely used in urology. The operation steps are as follows: 1. the patient gets the flat lying lithotomy position after emptying the bladder, and the perineum part is disinfected and paved conventionally, and then the ureter is inserted through the urethra. After the perfusion medicine is prepared, about 10ml of air is reserved in the injector for emptying residual perfusion liquid in the urine tube. 2. After the perfusion is finished, the ureter can be pulled out, and if the ureter needs to be kept, the ureter is closed for 2 hours. At the same time, the patient is ordered not to urinate within 2h as much as possible. The patient is ordered to take the horizontal position, the left lateral position, the right lateral position and the prone position for 15 minutes respectively in sequence within 2 hours.
The traditional bladder perfusion tube is a common urinary catheter which is usually used by people, and the opening of the common urinary catheter is mainly used for urination, so the radius is large, and leakage and environmental pollution are easy to occur when a syringe is used for injecting medicine. In addition, the inner wall of a common urinary tube is smooth and free from shielding, and the medicine is easy to flow out again along the pipeline after being injected, so that the loss of the medicine and the environmental pollution are caused, and particularly, the problem of the environmental pollution caused by the leakage of the medicine (especially the chemotherapeutic medicine) in the perfusion and chemotherapy process of bladder tumors is not negligible.
SUMMERY OF THE UTILITY MODEL
The main object of the utility model is to provide a bladder perfusion tube, can effectively solve the problem among the background art.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a bladder perfusion tube, includes the perfusion pipe, the perfusion pipe top can be dismantled and is connected with the needle tubing connector, be equipped with the needle tubing inserted hole in the needle tubing connector, just the needle tubing inserted hole is innermost to be linked together with the perfusion pipe entry. And an anti-backflow valve is arranged on the inner wall of the perfusion catheter. The center of the tail end of the perfusion catheter is provided with a perfusion opening.
Furthermore, 10-14 sets of backflow-preventing valves are arranged on the inner side wall of the perfusion catheter, and each set of backflow-preventing valves comprises two mutually opposite backflow-preventing valves.
Further, the needle tube connector is a cylinder, and the radius of the cylinder is larger than that of the perfusion catheter.
Further, the needle tube insertion opening has a radius that gradually decreases from the outside to the inside, and the innermost radius is smaller than the radius of the infusion catheter inlet.
Furthermore, the outer wall of the needle tube connector is frosted.
Preferably, the needle tube connector is made of rubber.
Compared with the prior art, the utility model discloses following beneficial effect has:
one, the utility model discloses in, it is connected with the rubber needle tubing connector that makes things convenient for the needle tubing nipple to insert to pour into the pipe top, and the needle tubing inserted hole in the needle tubing connector diminishes by top radius to bottom gradually, and the radius is less than and pours into pipe opening radius bottommost, like this after the needle tubing nipple inserts the needle tubing inserted hole, needle tubing inserted hole inner wall rubber can tightly wrap up the needle tubing breast, has avoided the leakage of liquid medicine on the one hand, and on the other hand makes the difficult slippage of needle tubing nipple.
Secondly, the utility model discloses in, be equipped with the anti-return valve on the pipe inner wall that pours into, can avoid the liquid medicine of pouring into the bladder to take place the backward flow.
Thirdly, the utility model discloses in, fill the pipe terminal positive center and seted up the mouth of filling for the liquid medicine can get into in the bladder the very first time, thereby can reduce the depth of insertion that fills the pipe.
Drawings
Fig. 1 is a schematic structural view of the bladder perfusion tube of the present invention.
In the figure: 1. a perfusion catheter; 2. a needle tube connector; 3. a needle tube insertion opening; 4. an infusion port; 5. an anti-reflux flap.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.
As shown in fig. 1, a bladder perfusion tube comprises a perfusion catheter 1, wherein the top end of the perfusion catheter 1 is detachably connected with a needle tube connector 2, a rubber needle tube insertion opening 3 is arranged in the needle tube connector 2, the innermost side of the needle tube insertion opening 3 is communicated with the inlet of the perfusion catheter 1, the radius of the needle tube insertion opening 3 gradually decreases from the outside to the inside, and the radius of the innermost side is smaller than the radius of the inlet of the perfusion catheter 1. On the inner side wall of the perfusion catheter 1 there are 12 sets of anti-reflux flaps 5, each set comprising two anti-reflux flaps 5 opposite to each other. The perfusion port 4 is arranged at the center of the tail end of the perfusion catheter 1. The needle tube connector 2 is a cylinder, and the radius of the cylinder is larger than that of the perfusion catheter 1. The outer wall of the needle tube connector 2 is frosted.
It should be noted that, the utility model relates to a bladder perfusion tube's theory of operation is: the perfusion catheter 1 is inserted into the bladder along the urethra, when urine flows out of the perfusion catheter 1, the opening of the perfusion catheter 1 is inserted into the needle tube connector 2, and the rubber inner wall in the needle tube connector 2 tightly wraps the opening of the perfusion catheter 1. Then, the needle tube nipple is inserted into the needle tube insertion opening 3, and the rubber on the inner wall of the needle tube insertion opening 3 tightly wraps the needle tube nipple. At the moment, the liquid medicine starts to be injected, the liquid medicine flows along with the perfusion catheter 1 and finally enters the bladder from the perfusion opening 4, and the liquid medicine is difficult to flow back under the action of the backflow prevention valve 5.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
