Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to a female urinary catheter. Background Art

[0002] Normal urination is a joint activity of the spinal reflex center and the sympathetic, parasympathetic, and somatic nerves. When any nerve related to urination is damaged, the resulting urination dysfunction is called neurogenic bladder. Neurogenic bladder and urethral dysfunction is a type of bladder and (or) urethral dysfunction caused by neuropathy or damage, often accompanied by bladder and urethral coordination disorders.

[0003] Neurogenic bladder and urethral dysfunction produces complex urination symptoms, among which difficulty in urination or urine retention is one of the most common symptoms. For this symptom, intermittent catheterization or continuous catheterization is usually adopted clinically. Some patients who cannot be cured usually need external catheterization for life and need to have a long-term indwelling catheter. The existing catheters are basically equipped with a fluid bag. This design is to discharge the urine in the bladder in time. However, because the fluid bag usually needs to be fixed on the patient's body surface or the inside of the pants, it is inconvenient for the patient to move, and it is also inconvenient to handle the fluid bag every time. At the same time, because the air injection hole on the catheter is exposed, it will also affect the stability of the airbag. In addition, the existing catheter is more troublesome to operate each time, and sometimes even requires nursing assistance, which is inconvenient to operate. Summary of the invention

[0004] The purpose of the present invention is to provide a female urinary catheter, which is convenient to carry and can be operated by the patient to urinate independently without hindering normal activities, thereby improving the quality of life of the patient.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] The core of the present invention is to provide a female urinary catheter, which is convenient to carry and can be operated by the patient to urinate independently without interfering with normal activities, thus helping to improve the patient's quality of life.

[0025] Please refer to Figure 1-5 , Figure 1 It is a structural schematic diagram of a female urinary catheter in a specific embodiment of the present invention; Figure 2 for Figure 1 Schematic diagram of the matching structure of the middle gas injection connector and the urinary catheter; Figure 3 for Figure 1 Schematic diagram of the middle shield structure; Figure 4 for Figure 1 Schematic diagram of the structure of the medium airtight water-absorbing membrane; Figure 5 for Figure 1 Schematic diagram of the closed state of the catheterization switch.

[0026] In a specific embodiment, the female urinary catheter provided by the present invention mainly includes a urinary catheter 1 with a hollow structure and an air injection connector 3 connected thereto. The air injection connector 3 is located at the lower end of the urinary catheter 1, and the two can be integrally formed. The upper end of the urinary catheter 1 is usually arc-shaped to provide comfort for users.

[0027] The "upper end" described herein and the "lower end" in the following text are based on the usage state of the female urinary catheter in the present invention.

[0028] The upper end of the urinary catheter 1 is provided with an air bag 2 and drainage holes 10. The drainage holes 10 are usually distributed within a certain vertical range starting from the upper end of the urinary catheter 1, and there may be several drainage holes 10.

[0029] An injection hole 30 is provided on the injection connector 3, and the injection hole 30 can be set on the outer wall of the injection connector 3. An injection valve is installed at the position of the injection hole 30, which is similar to the injection one-way valve on a basketball. An trachea 4 is fixedly provided in the catheter 1 along its length direction, and both ends of the trachea 4 are respectively connected to the airbag 2 and the injection hole 30.

[0030] The gas injection connector 3 is provided with an outflow hole 31 connected to the urinary catheter 1. The outflow hole 31 can be set on the lower surface of the gas injection connector 3. The drainage hole 10 above the urinary catheter 1 is connected to the inside of the urinary catheter 1, so that urine can enter the urinary catheter 1 through the drainage hole 10 and then flow out from the outflow hole 31.

[0031] A urinary catheter switch 5 is provided at the lower end of the urinary catheter 1 , and the switch 5 is arranged above the gas injection joint 2 .

[0032] The urinary catheter switch 5 of the present invention can be a snap-on switch, which is composed of a first card plate 50 and a second card plate 51. Figure 5 As shown, the first clamping plate 50 and the second clamping plate 51 are hinged to each other, and the hinged position is fixed on the outer wall of the urinary catheter 1, so that the first clamping plate 50 and the second clamping plate 51 can move toward each other around the hinged position to close, and the other end of the first clamping plate 50 is provided with a buckle extending directly opposite to the second clamping plate 51, and the second clamping plate 51 is provided with a bayonet at a corresponding position. When the switch 5 is closed, the buckle on the first clamping plate 50 is embedded in the bayonet on the second clamping plate 51, so that the urinary catheter 1 is clamped, and the purpose of opening and closing control of the urinary catheter 1 can be effectively achieved. The structure is simple and easy to manufacture.

[0033] In order to further improve the reliability of the switch 5, a protrusion facing the second card plate 51 can be provided on the inner side of the first card plate 50, and a groove is provided at the corresponding position on the second card plate 51, so that when buckled, the corresponding position of the catheter 1 can be bitten to improve the sealing strength and prevent urine from penetrating after the switch 5 is closed.

[0034] The female urinary catheter further comprises a detachable shield 6, which is used to protect the gas injection connector 3. The shield 6 may be a hollow cone structure, and may be composed of two symmetrical parts, which are combined into a whole, and its interior is adapted to the gas injection connector 3, and the gas injection hole 30 is covered, so as to protect the gas injection hole 30, which can ensure the normal use of the airbag 2, and at the same time, the gas injection valve installed at the gas injection hole 30 can be prevented from causing friction to the patient's skin, further improving the patient's comfort, and the shield 6 can be directly removed during rest without affecting normal use, which helps to improve the quality of rest.

[0035] In addition, a through hole connected to the outflow hole 31 is also provided at the bottom of the shield 6 , so that when the shield 6 is installed, the urine discharged from the outflow hole 31 can flow out from the through hole 60 .

[0036] As an improvement, an internal thread may be provided on the inner wall of the shield 6, and an external thread may be provided on the outer wall of the gas injection connector 3 near the middle, so that the shield 6 and the gas injection connector 3 are threadedly matched, which makes it easy to adjust the tightness of the two.

[0037] The shape of the shield 6 can be further set: for example, its bottom wall is set to be concave, lower than its bottom outer edge, and the bottom wall has smooth convex particles protruding outward, and a through hole 60 is opened in the middle of the bottom wall. The setting of the above-mentioned smooth convex particles makes its appearance like a lotus pod, which can effectively increase the concealment of the through hole 60, and the shape is beautiful, which can avoid embarrassment caused by carrying.

[0038] In a specific embodiment, a sanitary napkin 7 can be covered on the outside of the protective cover 6. Specifically, the overall structure of the sanitary napkin 7 is a circular spiral (similar to the shape of a rotated apple peel), and its upper end is wrapped around the catheter 1 and located above the switch 5, and then spirally covered on the protective cover 6. In this way, there is no need to fix the sanitary napkin 7 with glue, thereby avoiding symptoms such as allergies and infections caused by adhesion. In order to further ensure the stability of the sanitary napkin 7, some spiral grooves can be correspondingly arranged on the outer wall of the protective cover 6 during design, which can further prevent the sanitary napkin 7 from sliding.

[0039] The sanitary napkin 7 may also adopt a multi-layer structure, for example, including a pure cotton absorption layer and a Chinese medicine treatment layer, which can increase its function, not only absorbing secretions, but also achieving a certain effect of treating gynecological diseases through the drugs on the Chinese medicine treatment layer.

[0040] In the present invention, the catheter 1, the catheter switch 5 and the shield 6 can all be made of plastic. The catheter 1 uses silicone with a relatively low hardness, while the catheter switch 5 and the shield 6 require a relatively high hardness material for convenient opening, closing or disassembly operations.

[0041] In a specific embodiment, the female urinary catheter may be further provided with: for example, an airtight water-absorbing membrane 8 may be rotatably provided at the lower part of the air injection joint 3, such as Figure 4 As shown, the airtight water-absorbing membrane 8 is provided with an opening 80, and the size of the opening 80 is adapted to the outflow hole 31. In the present invention, the airtight water-absorbing membrane 8 is installed on the gas injection joint 3 through a mounting frame 81. The mounting frame 81 is annular, and its inner wall is provided with an internal thread. The lower end of the gas injection joint 3 is provided with an external thread adapted thereto. The mounting frame 81 and the gas injection joint 3 are threadedly matched, and the airtight water-absorbing membrane 8 is fixed to the lower end surface of the mounting frame 81. In this way, by rotating the mounting frame 81, the opening 80 can be directly opposite the outflow hole 31 or offset therefrom. When the opening 80 and the outflow hole 31 are completely offset, the airtight water-absorbing membrane 8 can cover the outflow hole 31, which can effectively prevent external viruses or dust from infecting the end of the outflow hole 31 or invading the interior of the guide tube 1, and can also play a certain adsorption role to prevent leakage.

[0042] The use process of the present invention is as follows:

[0043] When in use, close the catheter switch 5, insert the upper part of the catheter into the bladder according to conventional catheterization, and expand the airbag 2 by air injection to ensure its retention stability, then connect the shield 6 to the air injection joint 3, and then cover the sanitary napkin pad 7. When the patient is catheterized, he only needs to go to the bathroom like a normal person, open the catheter switch 5 with one hand, and urinate, without carrying a fluid bag at any time, reducing his psychological burden. At the same time, because there is no fluid bag, the patient can also have a larger range of motion, which is conducive to the patient's physical exercise and improve the quality of life. Secondly, when the patient rests at night, the shield 6 can be removed, and the airtight water-absorbing film 8 can be rotated to block the outflow hole 31, effectively reducing the probability of virus invasion and infection, and can also absorb a certain amount of permeate. At the same time, without the shield 6, its comfort is relatively increased, which is conducive to the patient's normal rest.
