Background

When the ureter is used, one end of the ureter is inserted into the bladder from the urethra, and the other end of the ureter is connected with the urine bag to introduce urine in the bladder into the urine bag. During the urine drainage, operations such as bladder manometry, bladder irrigation, liquid medicine injection into the bladder and the like are often performed, and a corresponding device is required to be connected with a urinary catheter.

Some of the clinical catheters have a pressure measuring flushing connector, and the pressure measuring flushing device is conveniently connected with the pressure measuring flushing connector, such as a urinary catheter disclosed in ZL 201621026704.7. Urinary catheters without pressure-measuring flushing connectors are also widely used, for example, the urinary catheter disclosed in ZL201420587961.2, which is inconvenient for pressure-measuring flushing.

In the urinary catheter drainage process, a continuous drainage mode is adopted most of the time, namely, the urinary catheter is kept smooth for a long time. But the urinary catheter pinch exercise is usually performed two to three days before the urinary catheter is pulled out to exercise the bladder function. The practice of clamping and closing the ureter refers to clamping and closing the ureter, opening the ureter for one time for two to three hours to urinate, and then clamping and closing the ureter, wherein the clamping and opening period of the ureter is the same as the urination period of a normal person.

As mentioned above, the practice of clamping and closing the urinary catheter requires opening the urinary catheter at regular time and the nurse to remember the opening time of the urinary catheter. However, in clinical practice, the condition that a nurse forgets to open the urinary catheter due to a large number of patients in a hospital and busy work is inevitable, so that the patient is uncomfortable due to too much urine, the bladder exercise effect is affected, and the bladder and other human organs can be damaged. And different patients have different water drinking conditions, the urine accumulated in the same time is different, and if the urine is accumulated in a sufficient amount and the time is short, the ureter is not opened, the problems are also caused.

The applicant intends to devise a urinary catheter connection control device to solve the above-mentioned problems.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the following detailed description.

As shown in fig. 1 to 3, the connection control device for the urinary catheter comprises a three-way valve 1, a bypass pipe 2 and a bypass pipe switch 3, wherein the three-way valve 1 is provided with a urinary catheter joint 12, a urine bag joint 13, a pressure measuring flushing joint 14 and a valve core 16; the urinary catheter joint 12 can be controlled to be communicated with any one of the urine bag joint 13 and the pressure measuring flushing joint 14 through the adjusting valve core 16, or the urinary catheter joint 12 is not communicated with the urine bag joint 13 and the pressure measuring flushing joint 14; the bypass pipe 2 is communicated with the urine pipe joint 12 and the urine bag joint 13, an overflow structure 21 is arranged in the bypass pipe 2, and the bypass pipe switch 3 is arranged on the bypass pipe 2.

When the utility model is used, the ureter joint 12 is connected with the ureter, and the urine bag joint 13 is connected with the urine bag. When the catheter connector 12 is communicated with the urine bag connector 13, normal urine drainage is performed. When the bladder pressure measurement is needed, the pressure measurement equipment is connected to the pressure measurement flushing connector 14, and the urinary catheter connector 12 is communicated with the pressure measurement flushing connector 14. When bladder irrigation or medicine injection is needed, corresponding equipment is connected to the pressure measuring irrigation joint 14, and the urinary catheter joint 12 is communicated with the pressure measuring irrigation joint 14; after the flushing is finished or the medicine is kept for enough time, the urine tube connector 12 is communicated with the urine bag connector 13, and the liquid is discharged. When the ureter needs to be closed, the ureter joint 12 is not communicated with the urine bag joint 13 and the pressure measuring flushing joint 14. It is thus clear that the utility model discloses use with the ureter cooperation that does not have the pressure measurement flushing joint, can conveniently carry out the bladder pressure measurement and wash, still can play the effect of ureter switch simultaneously concurrently.

During normal drainage, the bypass line 2 is closed. When bladder exercise is needed, the bypass pipe switch 3 is opened, the bypass pipe 2 is opened, if the connection control device is adjusted to close the ureter and forgets to open on time, and the bladder pressure reaches the upper limit of the bladder safety pressure, the overflow structure 21 is opened to discharge partial urine, so that the bladder pressure is prevented from exceeding the upper limit of the safety pressure, and discomfort of a patient and damage to the bladder and other human organs are avoided. When the bladder pressure does not reach the upper safety limit, the overflow structure 21 is not opened, and the effect of closing the ureter is not influenced.

The structure of the three-way valve 1 is similar to that of the existing medical three-way valve, and mainly the form of a joint is changed. It is clear that the urinary catheter adapter 12 should be adapted to a urinary catheter, and that the urinary catheter adapter 12 is a conical and stepped adapter according to the prior art urinary catheter construction, as shown in fig. 1. The urine bag connector 13 should match with the existing urine bag, and the urine bag connector 13 is a conical elastic connector according to the joint structure of the existing urine bag. The joint of the existing urine tube is made of the same material as the urine tube, is very soft, and is very inconvenient to connect the urine bag. The urine bag connector 13 is preferably harder than the connector of the existing urine tube, so that the connection is convenient, the shake of the urine bag connector 13 when the connector of the urine bag is pulled out is avoided, and the urine is prevented from being spilled. The bypass line switch 3 can be a common flow stop clamp.

Similar with current three-way valve, the utility model discloses a three-way valve 1 accessible is rotatory case 16 and is realized the intercommunication relation regulation that each connects. FIG. 4 is a schematic view of the valve cartridge 16 when the catheter adapter 12 is in communication with the urine bag adapter 13; FIG. 5 is a schematic view of the valve cartridge 16 with the urinary connector 12 in communication with the pressure flushing connector 14; fig. 6 is a schematic view of the cartridge 16 when the urinary catheter connector 12 is not in communication with both the urine bag connector 13 and the pressure flushing connector 14.

When the conventional use of ureter lasts the drainage, the urine bag position of being connected with the ureter is lower, and the urine does not have the refluence risk usually. However, in some special cases, such as when the patient is transported, there may be a risk of urine backflow after the urine bag is elevated. In order to avoid the urine from flowing back into the bladder, the urine bag connector 13 is provided with a backflow prevention structure 15. The anti-reflux structure 15 is preferably a one-way valve arranged towards the urine bag connector 13. One-way valves are known in the art, which are shaped as conical thin sheets with radial slits, the material of which is elastic. When urine flows in the positive direction, namely flows from the bottom of the valve to the tip direction, the valve is easy to be opened, namely the opening pressure of the valve in the direction is very small; when the liquid flows reversely, the valve is not easy to be opened, namely, the opening pressure of the valve in the direction is higher, and the reverse flow prevention effect can be achieved.

The overflow structure 21 is a structure that can be opened under a certain pressure, and can discharge urine when being opened, so that the overflow effect is achieved. The overflow structure 21 is preferably a one-way valve arranged towards the urinary catheter hub 12. The opening pressure of the overflow structure 21 is set according to the upper bladder safety pressure limit, i.e. preferably 40cm water column pressure. The opening pressure of the one-way valve can meet the requirement by controlling the parameters such as the material size and the like of the one-way valve.
