Description

Technical Field

[0001] The invention belongs to the field of medical tools, and in particular relates to a split-type leak-proof urinary catheter. Background Art

[0002] The split-type anti-leak urinary catheter is a medical device specially designed to reduce the risk of urine leakage. This type of catheter is usually used for patients who require long-term or short-term catheterization, including postoperative recovery, serious illnesses, and difficulty in urinating independently.

[0003] The structure of the urinary catheter in the existing technology is relatively simple, but it can meet the needs of most people. However, the pelvic floor muscles of elderly women are weak and the estrogen level decreases, which leads to a decrease in urethral closure pressure. As a special group, elderly women still have a large amount of urine leakage when using existing urinary catheters. Obviously, there is no urinary catheter on the market that is completely suitable for elderly women. The large amount of urine leakage will cause incontinence dermatitis on the skin of elderly women, which greatly affects their health. Therefore, the scope of application of urinary catheters needs to be changed. At the same time, the fixing patches used in existing urinary catheters are prone to allergies, need to be replaced frequently, and are extremely easy to damage the skin. In addition, they are not sticky enough and often fall off automatically, affecting the installation stability of the catheter. Summary of the Invention

[0028] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0029] As attached Figure 1 To the attached Figure 7 As shown:

[0030] Example 1:

[0031] The present invention provides a split-type leak-proof urinary catheter, comprising an insertion tube 1, one end of the insertion tube 1 being integrally fixedly connected to a pointed tip 4, and the other end of the insertion tube 1 being integrally fixedly connected to a connecting tube 7, the connecting tube 7 being used to communicate with an input tube of a urine collection bag, a branch tube 8 being fixedly and centrally symmetrically passed through the side wall of the connecting tube 7, a valve 9 being installed on the branch tube 8, a urine inlet 3 being centrally and symmetrically opened near the pointed tip 4 of the insertion tube 1, a position of the insertion tube 1 near the urine inlet 3 being provided with an anti-slipping member 2 for preventing the insertion tube 1 from detaching, the anti-slipping member 2 comprising a water injection balloon 21 fixedly connected to the insertion tube 1, a group of branch tubes 8 extending into the interior of the connecting tube 7 and being connected to a water delivery pipe 22, the water delivery pipe 22 passing through the insertion tube 1 and extending into the water injection balloon 21;

[0032] The insertion tube 1 is also provided with a leak-proof member 5 for further preventing urine leakage. The leak-proof member 5 includes an inflatable cuff 51 fixedly connected to the middle of the insertion tube 1. A set of branch pipes 8 extend into the interior of the connecting pipe 7 and are connected to an air supply pipe 53. The air supply pipe 53 passes through the insertion tube 1 and extends into the inflatable cuff 51. The air supply pipe 53 is located at one end of the inflatable cuff 51, and the water supply pipe 22 is located at one end of the water-filled balloon 21. Both are provided with a dispersing member 11 for dispersing the air or water flow.

[0033] One end of the insertion tube 1 close to the connecting tube 7 is provided with a fixer 6 for fixing the integral urinary catheter to the inner thigh of the patient. The fixer 6 includes a fixing patch 61 on which an elastic bandage 65 and a moisture indicator strip 62 are provided.

[0034] As can be seen from the above, the medical staff inserts the insertion tube 1 into the patient's urethra, inputs water into the water-injected balloon 21 through the branch tube 8, and the water-injected balloon 21 fixes the position of the insertion tube 1. Then, air pressure is input through the air supply tube 53 to inflate the inflatable cuff 51, so that the inflatable cuff 51 provides secondary support to the urethral wall to prevent urine leakage.

[0035] See Figure 1 The branch pipe 8 connected to the gas pipe 53 is also connected to a mounting pipe, in which a pressure sensor 52 is installed. The pressure sensor 52 is electrically connected to the controller, and the controller is electrically connected to the display device.

[0036] As can be seen from the above, when the air is delivered by the air supply tube 53, the air pressure in the branch tube 8 is sensed by the pressure sensor 52, and the input air pressure is adjusted according to the urine leakage situation to avoid tissue ischemia. The pressure sensor can then provide real-time feedback on the inflation cuff pressure to avoid overinflation (the alarm threshold is 20 cmH2O, and exceeding this threshold will trigger an alarm).

[0037] See Figure 5 and Figure 6The fixing patch 61 is a double-layer structure, the layer close to the skin is a medical silicone adhesive layer 611, and the other layer is an antibacterial coating 612, which is a silver ion coating.

[0038] As can be seen from the above, the provision of a medical silicone adhesive layer 611 can reduce the frequency of allergic reactions. The porous silicone structure is sufficiently breathable and is not prone to local burning. It can be used continuously for a long time without frequent replacement. At the same time, the elastic silicone adaptively deforms with limb movement and is not easy to fall off, effectively ensuring the stable fixation of the fixator 6. The use of an antibacterial silver ion coating can reduce the risk of infection and avoid the emergence of new diseases. When the viscosity of the medical silicone adhesive layer 611 decreases, a special silicone enhancement spray can be used directly to restore the viscosity.

[0039] See Figure 5 The humidity indicator strip 62 is impregnated with cobalt dichloride.

[0040] From the above, we can see that based on the principle that cobalt dichloride changes color when it comes into contact with water, it changes from blue to pink to determine whether urine leakage occurs. The color change range of cobalt dichloride is between 30%-70% relative humidity, and it can change color within 5-10 minutes. Through color change warning, urine leakage can be dealt with in time to reduce the probability of dermatitis.

[0041] See Figure 5 One side of the elastic bandage 65 is fixedly connected to the fixing patch 61 , and the other symmetrical side of the elastic bandage 65 is fixedly connected with a plurality of hanging holes 64 , and the fixing patch 61 is fixedly connected with hooks 63 corresponding to the hanging holes 64 one by one.

[0042] The elastic bandage 65 is an elastic silicone cushioning band, and the side thereof in contact with the insertion tube 1 is a frosted surface.

[0043] As can be seen from the above, the insertion tube 1 is fixed to the fixing sticker 61 by docking the hanging opening 64 and the hook 63, so that the insertion tube 1 can be quickly fixed. The frosted surface increases the friction effect to ensure the stable fixation of the insertion tube 1. The insertion tube 1 and the fixer 6 are fixedly connected by an elastic silicone buffer belt. The elastic silicone buffer belt is elastic and has less damage to human skin.

[0044] See Figure 7 A plurality of inner support frames 10 are fixedly connected linearly and equidistantly in the insertion tube 1, and the inner support frame 10 is a tripod support frame.

[0045] Each side of the tripod is provided with a through hole 101 .

[0046] As can be seen from the above, the internal support frame 10 can provide internal support for the insertion tube 1, ensuring the patency of the insertion tube 1 during use, and avoiding the problem that the insertion tube 1 is squeezed by the patient's internal muscles and makes it difficult to urinate.

[0047] Example 2:

[0048] This embodiment is basically the same as the previous embodiment, except that Figure 2 and Figure 3 The dispersing part 11 includes an annular tube 111 which is sleeved on the insertion tube 1 and located inside the water injection balloon 21 and the inflatable cuff 51. The annular tube 111 inside the water injection balloon 21 and the inflatable cuff 51 is connected to the water pipe 22 and the air pipe 53 respectively. The outer circumference of the annular tube 111 is equidistantly connected to a plurality of branches 112.

[0049] As can be seen from the above, the air flow and water flow are dispersed by the cooperation of the ring tube 111 and the branch head 112 to avoid the concentrated outflow of water or gas, which would cause the water-filled balloon 21 or the inflatable cuff 51 to bulge locally, which is not conducive to the fit with the urethra and would increase the patient's pain.

The specific connection methods of each part adopt conventional means such as bolts, rivets, and welding that are mature in the prior art.
