Description

Technical Field

[0001] The present invention relates to the technical field of medical supplies, and in particular to a non-invasive inductive negative pressure drainage urinary catheterization device, a urine-absorbing pad, and a diaper. Background Art

[0002] With the development of society and the improvement of people's living standards, medical technology has also made great strides, and various new treatment methods and technologies have emerged in medical research. However, for disabled, paraplegic, and incapable female patients, nerve damage causes the muscles that control the bladder to lose function, making it difficult for them to actively urinate. In-dwelling catheters are now commonly used. Long-term indwelling catheters will increase the probability of urinary tract retrograde infection; secondly, frequent insertion and removal of catheters will cause unbearable discomfort and pain to patients; finally, repeated extraction of residual urine in the bladder can easily cause damage to the bladder mucosa, causing inflammation and hematuria, and increase the labor intensity of medical staff and increase economic costs. Due to these shortcomings of in-dwelling catheters, many nursing homes will use diapers or urine pads as alternative urination solutions for paraplegic patients. Due to the uneven quality of nursing staff and the importance of daily nursing work, diapers are often replaced in time, resulting in the room being filled with urine odor and difficult for ordinary people to enter, and even often causing urinary tract infections and bedsores. Therefore, in order to meet the needs of quickly and comfortably draining excess residual urine from the body, reduce the intensity of nursing work for medical staff, and alleviate the discomfort of patients, it is necessary to develop a new, convenient, non-invasive catheterization device. Summary of the invention

[0003] The purpose of the present invention is to overcome the defects of the above-mentioned prior art and provide a non-invasive inductive negative pressure drainage catheterization device, urine absorbent pad, and diaper, which can effectively reduce the discomfort of female patients and reduce the nursing workload of medical staff.

[0004] The purpose of the present invention can be achieved by the following technical solutions:

[0005] One of the technical solutions of the present invention is to provide a non-invasive inductive negative pressure drainage catheterization device, comprising:

[0006] The urine absorbing rod comprises an outer shell layer with a first opening on one side, a urine absorbing layer located in the outer shell layer and exposed at the first opening, and a guide tube passing through the urine absorbing layer and having a plurality of openings and / or grooves on the side wall;

[0019] Furthermore, the urine absorbent layer also includes a first antibacterial layer and a second antibacterial layer, the first antibacterial layer is arranged between the first non-woven fabric layer and the water absorption factor layer, and the second antibacterial layer is arranged between the second non-woven fabric layer and the water absorption factor layer.

[0020] Furthermore, the first antibacterial layer and the second antibacterial layer are made of biological antibacterial materials, including nano silver ions, tea tree essential oil, and chitosan, to protect users from the risk of bacterial infection.

[0021] Furthermore, when the side wall of the diversion tube is provided with openings, the openings are arranged in a display manner, and a urination sensor is provided next to each opening;

[0022] When the side wall of the guide tube is provided with slots, the slots are spaced apart in a circumferential shape, and a plurality of urination sensors are provided beside each slot;

[0023] When the side wall of the guide tube is provided with openings and slots, the openings and slots are distributed at intervals, and a urination sensor is provided next to each opening and slot.

[0024] Furthermore, the distance between each urination sensor and the corresponding opening or slot is 1 to 3 mm.

[0025] Furthermore, one slot is provided with 3 to 5 urination sensors along its axial direction.

[0026] Furthermore, when the openings and the slots coexist, the openings are arranged in a display manner, and the slots are distributed between two rows of openings along the axial direction of the flow guide tube.

[0029] Furthermore, the controller can be a mainstream single-chip microcomputer or a processor of x86 architecture, ARM architecture, or RISC-V architecture.

[0030] The second technical solution of the present invention is to provide a urine-absorbing pad, which includes the non-invasive inductive negative pressure drainage catheterization device.

[0031] Furthermore, the urine-absorbing pad is provided with a first groove for placing the urine-absorbing rod, and a second groove connected to the first groove and for the drainage tube to pass through.

[0032] Furthermore, a first net bag for fixing the urine-absorbing rod is provided on the surface of the first groove.

[0033] The third technical solution of the present invention is to provide a diaper, which includes the non-invasive inductive negative pressure drainage catheterization device.

[0036] Furthermore, the urine-absorbing rod is provided with different sizes to meet the needs of people of different body shapes and ages, so that it can also be used in baby diapers.

[0037] Compared with the prior art, the present invention has the following advantages:

[0038] (1) The urine absorbing layer of the urine absorbing rod of the non-invasive inductive negative pressure drainage urinary catheterization device of the present invention contacts the female patient's genitals, thereby preventing the patient from feeling uncomfortable due to inserted urinary catheterization. When urine is discharged into the urine absorbing layer, it is extracted by a vacuum pump to form a negative pressure in the urine storage container, and urine in the urine absorbing rod is extracted through the drainage tube and the guide tube, so that the urine absorbing layer of the urine absorbing rod is always kept dry.

[0039] (2) The present invention uses a urination sensor located on one side of the opening and / or groove of the guide layer to sensitively detect when urine is discharged, and controls the vacuum pump to start and empty it through the controller; after emptying, the vacuum pump is controlled to shut down through the controller. This avoids excessive urine storage in the urine-absorbing rod due to the patient or medical staff not turning on the vacuum pump in time, and also avoids the discomfort caused to the patient by the airflow formed by the long-term opening of the vacuum pump.

[0040] (3) The design of the position of the openings and / or grooves in the present invention allows the patient's urine to fall into any part of the urine absorption layer, which can be sensitively monitored by the urination sensor and sucked into the drainage tube through the openings and / or grooves, and then enter the urine storage container through the drainage tube. This avoids the situation where urine is produced but not detected by the urination sensor due to inaccurate positioning, and it is not necessary to wait for a certain amount of urine to be produced before it can be detected. This setting makes urine detection more sensitive, so that the urine absorption stick always remains dry, improves the patient's comfort, and avoids allergies, itching, and redness and swelling caused by the patient's genitals being in a humid environment for a long time.

[0041] (4) The present invention provides a liquid level sensor and an alarm for monitoring the height of stored urine on the outer side wall of the urine storage container; a liquid discharge port is provided at the bottom of the side wall of the urine storage container, and a valve is provided at the liquid discharge port; the liquid level sensor and the alarm are connected to the controller. When the liquid level sensor detects that the urine level in the urine storage container reaches a certain height, the signal is transmitted to the controller to control the alarm to sound an alarm, reminding medical staff to discharge urine from the urine storage container. This can effectively avoid the vacuum pump from not working or urine backflow caused by the urine in the urine storage container being too full. BRIEF DESCRIPTION OF THE DRAWINGS
