Description

A urinary catheter for preventing gas reflux

technical field

The utility model relates to a urinary catheter, in particular to a urinary catheter for preventing gas reflux.

Background technique

Urinary Catheter A common medical device that is inserted into the bladder through the urethra to drain urine. After the front end of the catheter is inserted into the bladder, the urine enters the inner cavity of the catheter from the catheter port, and then flows into the drainage bag from the back end. When high-intensity focused ultrasound is used to treat benign gynecological diseases, patients usually require indwelling urinary catheters. And find that there are many patients clinically, in the process of indwelling the urinary catheter, extraneous gas enters in the bladder through the urinary catheter. When the gas enters the bladder, it will seriously affect the establishment of the focused ultrasound sound channel, which in turn will affect the entire high-intensity focused ultrasound treatment process, cause damage to the bladder, and affect the final treatment effect.

Utility model content

In view of the above technical problems, the utility model provides a gas reflux preventing urinary catheter that only allows urine to flow out.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: a catheter for preventing gas reflux, including a tube body, the front end of the tube body is provided with a catheter opening that allows urine to flow into the inner cavity of the tube body. The rear end of the tube is connected to the liquid inlet of a manual valve that can control the opening of the inner cavity of the tube, and the liquid outlet of the manual valve is connected to the drainage bag.

Preferably, a balloon is provided at the front end of the tubular body, and the balloon communicates with a liquid injection tube disposed in the tubular body.

Preferably, the manual valve includes a valve body formed with a valve cavity, the upper side of the valve cavity can communicate with the liquid inlet, and the lower side communicates with the liquid outlet, and the valve cavity is provided with a The spool of the liquid inlet is driven to rotate by a handle arranged outside the valve body.

Preferably, the spool includes a shielding portion that shields the liquid inlet and a connecting portion fixedly connected to the shielding portion, the connecting portion is fixedly connected to a rotating shaft on one side of the liquid inlet, and the rotating shaft is driven to rotate by the handle.

Preferably, a shaft hole is provided in the valve body, one end of the rotating shaft is threadedly connected to the shaft hole, the other end is provided with the handle, and the middle part is fixedly connected to the connecting part.

It can be known from the above technical scheme that the utility model can change the opening degree of the internal cavity of the tube by rotating the spool of the manual valve, that is, change the size of the window connecting the internal cavity of the tube with the outside world, thereby ensuring that only the catheter is allowed to Urine flows out without allowing outside air to flow into the bladder, providing a good environment for high-intensity focused ultrasound therapy.

detailed description

Below in conjunction with Fig. 1, Fig. 2 introduce the utility model in detail:

A urinary catheter for preventing gas reflux, including a tube body 1, which is generally made of plastic, rubber, etc. The front end of the tube body is provided with a catheter opening 11, when the catheter is indwelling, urine can flow from the catheter The urinary catheter enters the internal cavity 12 of the tube, and the rear end of the tube is connected to the liquid inlet 31 of the manual valve 3 that can control the opening of the internal cavity of the tube. The liquid outlet 32 of the manual valve is connected to the drainage bag (not shown in the figure). In the implementation process, after the urine entering the inner cavity of the tube flows to its rear end, the opening of the inner cavity is properly controlled through the manual valve, so that only the urine is allowed to flow out of the tube body, and the outside air is not allowed to flow into the tube body. In the present utility model, the front end of the tube body is provided with a balloon 5, which communicates with the liquid injection tube 6 arranged in the tube body, and injects liquid into the balloon through the liquid injection tube to expand the balloon. Thereby guarantee that this urinary catheter stays in the bladder stably.

Specifically, the manual valve 3 includes a valve body 34 formed with a valve cavity 33, the upper side of the valve cavity can communicate with the liquid inlet 31, and the lower side communicates with the liquid outlet 32. A valve core 35 that can block the liquid inlet is provided, and the valve core is driven to rotate by the handle 7 provided outside the valve body. During implementation, when you find that there is less urine, you can turn the handle appropriately so that the valve core can cover the liquid inlet more, thereby reducing the opening of the inner cavity. At this time, only the urine that flows into the rear end of the tube body It flows into the valve cavity from the gap between the liquid inlet and the valve core, and then flows into the drainage bag from the liquid outlet to prevent gas backflow; when there is more urine, you can turn the handle in reverse to make the valve core less Block the liquid inlet as much as possible, so as to increase the opening of the inner cavity, ensure that the urine flows into the drainage bag faster, and prevent excessive urine from accumulating in the bladder.

In the present utility model, the valve core 35 includes a shielding portion 36 that blocks the liquid inlet and a connecting portion 37 that is fixedly connected to the shielding portion. The rotation is driven by the handle; turning the handle can drive the rotating shaft to rotate, and the rotating shaft passes the connecting part to make the shielding part rotate around the rotating shaft, thereby adjusting the gap between the liquid inlet and the valve core, and realizing the purpose of adjusting the opening of the inner cavity of the tube. In the implementation process, a shaft hole 38 is arranged in the valve body, one end of the shaft is threadedly connected to the shaft hole, the other end is provided with the handle, and the middle part is fixedly connected to the connecting part. The threaded connection method is not only simple and quick to process, but also It can facilitate the accurate and stable positioning of the rotating shaft at any time during forward and reverse rotation, ensure that there is any gap between the liquid inlet and the valve core, and realize the purpose of arbitrarily adjusting the opening of the inner cavity of the tube.

The above-mentioned embodiments are only for the purpose of illustrating the utility model, rather than limiting the utility model. Those of ordinary skill in the relevant technical fields can make various changes and modifications without departing from the spirit and scope of the utility model , so all equivalent technical solutions should also belong to the category of the present utility model.
