Embodiment 1

[0052] see Figure 1-Figure 11 , a urinary catheterization device is provided in this embodiment, including a first structure part 101 for placing in the patient's bladder 501 and a second structure part 102 for indwelling in the patient's urethra 502, such as Figure 11 As shown, the first structural part 101 is provided with a closed urinary catheterization cavity, and the second structural part 102 is provided with a urinary catheterization channel, and the first structural part 101 is connected to the second structural part 102, And the catheterization cavity is connected with the catheterization channel, the second structure part 102 is used to expand elastically in the patient's urethra 502 and be fixed in the urethra 502; the first structure part 101 is also provided with several The catheter port 110 connected to the catheter cavity, the catheter port 110 is provided with an on-off mechanism, the on-off mechanism is used to open when the external pressure of the first ...

Embodiment 2

[0069] This embodiment provides a catheterization kit, including an adsorption device 400 and the catheterization device 100 described in Embodiment 1, the second elastic skeleton piece 106 is made of magnetic material or the inner part of the second elastic skeleton piece 106 A magnetic part is provided on the side, and the adsorption device 400 includes an extension rod 401, an adsorption part 402 arranged at the front end of the extension rod 401, and a wire 403. Several electromagnets 404 are arranged in the circumferential direction of the adsorption part 402, and the wire 403 is set In the extension rod 401, and one end of the wire 403 is connected to the electromagnet 404, and the other end of the wire 403 is used to connect the power supply; in this embodiment, the second structure part 102 of the urinary catheter 100 has magnetic;

[0070] When installing this urinary catheterization device 100, if Figure 14 As shown, the urinary catheter 100 can be sleeved on the a...

Embodiment 3

[0080] Since the number of the second elastic skeleton sheets 106 is limited, when each second elastic skeleton sheet 106 is in an open state, when the second diaphragm 107 between adjacent two second elastic skeleton sheets 106 is tightened, as shown in FIG. 15 and Figure 17 As shown, there is a difference in pressure between the second diaphragm 107 and the urethra 502, especially the pressure between the second diaphragm 107 at the middle position of the two second elastic skeleton pieces 106 and the side wall of the urethra 502 is the smallest, and the sealing effect is relatively strong. Poor; so the main difference between the present embodiment 3 and the above-mentioned embodiment 1 is that in the catheterization device provided by the present embodiment, in order to enhance the sealing effect, the second diaphragm 107 between the adjacent two second elastic skeleton sheets 106 A number of sealing protrusions 601 are also provided so that they can be embedded in the si...

Abstract

The invention relates to a catheterization device and a catheterization external member. The catheterization device comprises a first structure part placed in a bladder of a patient and a second structure part kept in the urethra of the patient, wherein a catheterization cavity in the first structure part communicates with a catheterization passage in the second structure part; the second structure part is elastically opened in the urethra of the patient, and is fixed in the urethra; the first structure part is also provided with a plurality of catheterization openings communicating with the catheterization cavity, an on-off mechanism is arranged at each catheterization opening, the on-off mechanisms are opened when the external pressure of the first structure part reaches set pressure andenable the catheterization cavity to communicate with the bladder of the patient, and the on-off mechanisms are closed when the external pressure of the first structure part is smaller than the set pressure and enable the catheterization cavity not to communicate with the bladder of the patient. The catheterization device disclosed by the invention is simple and compact in structure, is convenient to mount, use and disassemble, can be kept in the body of the patient for a long term, can greatly reduce the infection rick of the urethra and can also effectively reduce the cost.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a catheterization device and a catheterization set. Background technique [0002] In clinical practice, for patients with urinary incontinence, uremia and the need to closely monitor urine output, it is usually necessary to place a catheter on the patient's body. The existing catheter is usually made of natural rubber, silicone rubber or polyvinyl chloride (PVC) When installing, one end of the catheter needs to be inserted into the bladder through the patient's urethra, and the other end of the catheter is left outside the urethra to connect the ureter and the urine storage bag through the ureter. To achieve the purpose of drainage of urine. [0003] Yet existing urinary catheter still has some deficiencies, 1, the installation process of existing urinary catheter is very cumbersome, usually needs the cooperation of many medical personnel to finish installation, 2, exist...
