Description

A new type of urinary catheter

technical field

The utility model relates to a novel urinary catheter.

Background technique

Some people with urinary diseases can walk freely or participate in work independently except that they have obstacles to urination, but the current catheterization device as shown in Figure 1 generally requires the patient to hang a device connected to the catheter on his back. The urine bag of urinary catheter is very inconvenient like that, and can not protect the user's personal privacy.

Utility model content

The purpose of the utility model is to provide a novel urinary catheter with simple structure and convenient use in order to overcome the deficiencies in the prior art.

In order to achieve the above object, the utility model adopts the following scheme:

A new type of urinary catheter, comprising a tube body, a balloon is provided on the tube body, an inflation channel communicating with the balloon is provided in the tube body, and a one-way valve that can close the inflation channel is provided on the air inlet. The valve is provided with an excretion channel in the tube body, a catheter opening connected with the excretion channel is provided at one end of the tube body, and an excretion chamber connected with the excretion channel is provided at the other end of the tube body, and a valve plug is arranged in the discharge cavity;

A new type of urinary catheter as described above, wherein the valve plug includes a valve body made of elastic material, and a channel that can communicate with the tube body is provided in the valve body. A closure block that passes through the channel and can be inserted by the syringe;

A new type of urinary catheter as described above, wherein the valve body is provided with an elastic sleeve capable of keeping the closing block in a closed state when the syringe is pulled out.

A novel urinary catheter as described above, wherein the valve plug is an on-off valve.

In summary, compared with the prior art, the beneficial effects of the utility model are: the utility model has a simple structure, and a valve plug is provided in the excretion chamber of the catheter, and when the user needs to urinate, he can go to the bathroom to open it. The valve can discharge the urine, and after the urine is discharged, it can be closed. The urinary catheter of the utility model can be hidden in the clothing of the user, which well protects the personal privacy of the user and brings many conveniences to the user.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:

A kind of novel urinary catheter as shown in Figure 2, comprises tubular body 1, is provided with balloon 9 on tubular body 1, is provided with the inflatable channel 10 that communicates with described balloon 9 in tubular body 1, enters The air port is provided with a one-way valve 12 that can close the inflation channel 10, and a discharge channel 11 is provided in the tube body 1, and a urinary catheter 2 communicated with the discharge channel 11 is provided at one end of the tube body 1. The other end is provided with a discharge chamber 3 communicating with the discharge channel 11 , and a valve plug 4 is provided in the discharge chamber 3 .

The valve plug 4 described in the utility model includes a silica gel valve body 5, and a passage 6 that can communicate with the pipe body 1 is provided in the valve body 5, and the passage 6 is provided on the passage 6 and can be closed. The closure block 7 inserted by the syringe is provided outside the valve body 5 with an elastic sleeve 8 that can keep the closure block 7 in a closed state when the syringe is pulled out.

The utility model has a simple structure. When in use, the catheter is first inserted into the urethra of the human body, and then the inflatable device or the liquid filling device is used to inflate or fill the inflatable channel with air, so that the tube body 1 is fixed in the urethra of the human body. There is a valve plug in the excretion cavity of the catheter. When the user needs to urinate, he can go to the toilet and insert the valve plug into the valve plug to form an excretion channel, and the urine can be discharged. After the urine is discharged, the syringe can be pulled out The needle cylinder and the valve plug will be in the closed state again under the action of the elastic sleeve. The urinary catheter of the utility model can be hidden in the clothing of the user, which well protects the personal privacy of the user and brings many conveniences to the user.
