Description

Medical care-free drainage device

Technical Field

The invention relates to the field of medical equipment, in particular to a medical monitoring-free drainage device.

Background

Some patients have had cystostomy for a variety of reasons: making a fistulization opening at the pubic bladder, inserting a urine drainage tube, and draining urine to the outside of the body through the urine drainage tube and a urine bag so as to redirect the urine temporarily or permanently. Normally, normal people can consciously control the urine discharge, but the patients who have performed the cystostomy cannot control the urine discharge consciously, and the patients need to regularly discharge urine by themselves or family members according to individual differences, usually every 2-4 hours, based on the fact that the bladder is not swollen.

The urine is discharged at regular time, so that the urine storage quantity in the bladder is not too small, the bladder is prevented from being shrunk or too large, and the establishment of the self-discipline or radioactive bladder is facilitated. Therefore, the patients and family members who perform the cystostomy need to pay attention to opening and closing the urine drainage tube at regular time, and the trouble of urination of the patients can be caused due to the carelessness at the moment. If the condition that can not in time put urine (promptly, the urine drainage tube is closed for a long time) appears, the patient can feel the bladder distending pain this moment, and urine also spills over from the stoma easily, pollutes the bedding, influences quality of life. On the other hand, if the urine drainage tube is left for too long (i.e., the opening time of the urine drainage tube is too long), the bladder tends to atrophy, and the bladder loses the urine storage function.

Some urethral catheterization devices capable of realizing automatic control have appeared, for example, patent No. 201420188065 entitled timing control device for medical catheter, which uses a switch unit to control a power supply unit to be connected with a power supply end of a solenoid pinch valve when a timer reaches a preset time, and then the solenoid pinch valve is closed to control the automatic opening of the medical catheter, thereby realizing the purpose of automatic urination. Although this patent can realize automatic urination, along with the increase of the closed number of times of solenoid valve clamp, the fracture appears easily in the urine drainage tube or glues the phenomenon, and this just needs to insert the urine drainage tube at patient's stoma again, and this not only can bring the misery for the patient, increases its medical expense, still can increase medical personnel's work load.

The driving part 1 provides electric energy for the adjustable time delay relay 2 and the electromagnetic tube pinch valve 4; the adjustable time delay relay 2 controls the electromagnetic pipe pinch valve 4 to cut off and open the special matched rubber pipe 5 at regular time through a control signal. The special matched rubber tube 5 is connected with the urine drainage tube 6 through the switching unit 7, and the aim of regularly discharging urine of a patient in cystostomy is fulfilled by opening and closing the special matched rubber tube 5. Meanwhile, the special matched rubber tube 5 can be conveniently replaced through the switching unit 7, and the phenomenon that the urine drainage tube is inserted into the stoma of the patient again is avoided.

The functions and specific structures of the components of the invention are as follows:

the driving unit 1 can be a 12V direct current power supply or a 12V storage battery, so that the patient can carry the driving unit conveniently, and the range of motion of the patient is not limited; or 220V alternating current is converted into a 12V power supply through a transformer so as to be convenient for the bedridden patient to use.

The adjustable time delay relay 2 is provided with a relay signal terminal 21, a relay equipment terminal 22, a function selection button 23 and a time adjustment button 24. The relay signal end 21 is connected with the signal end of the electromagnetic tube pinch valve 4 through a signal connecting wire 9; the relay device end 22 is connected with the driving unit 1 and the solenoid pinch valve 4 through the power connecting line 3 respectively. A short press on the function selection button 23 can generate a control signal which is transmitted to the pinch valve 4 via the signal connection 9, thereby controlling the extension or retraction of the valve head of the pinch valve. The number of the time adjusting buttons 24 is two, and the delay time range can be set by long pressing the function selecting button 23 and matching with the two time adjusting buttons 24, wherein the minimum delay time is 0.1 second, and the maximum delay time is 999 minutes. The set time delay parameter is permanently memorized after power-off and is re-timed in an initial state after re-power-on.

To avoid accidents and to cope with emergency incidents, the function selection button 23 is set with the highest priority authority: in any case, by pressing the function selection button 23 for a short time, the current state of the solenoid pinch valve 4 is immediately deactivated: the original open state is changed to be closed, and the original closed state is changed to be opened.

The solenoid pinch valve 4 includes: the signal end of the electromagnetic tube pinch valve 4 is connected with the adjustable delay relay 2 through a signal connecting wire 9, the electromagnetic solenoid is connected with the adjustable delay relay 2 through a power connecting wire 3, and the electromagnetic solenoid drives the valve head 41 to stretch out or retract according to a control signal of the signal end of the electromagnetic tube pinch valve 4.

The fixing member is not limited to the pin, and may be other fixing members such as round steel and flat steel, and may be fixed in the sleeve 42 by other means such as welding or a jackscrew. The installation position of the fastener is determined according to the extending and retracting stroke of the valve head 41 and the diameter of the special matched rubber tube 5, and specifically comprises the following steps: when the valve head 41 extends out, the valve head 41 extrudes the matched rubber tube 5 on the fixing piece of the limiting device 43, so that the liquid flowing in the matched rubber tube 5 is blocked; after the valve head 41 retracts, the gap between the valve head 41 and the limiting device 43 can ensure that liquid in the matching rubber pipe flows smoothly.

In order to adjust the gap between the valve head 41 of the electromagnetic pipe clamp valve and the position-limiting device 43, the position-limiting device 43 may also include a fixed part and a movable part. The fixing piece is fixed in the sleeve 42, which can be a pin column, or other fixing pieces such as round steel and flat steel, and the center of the fixing piece is provided with a screw hole. The arrangement of the movable member with one end facing the valve head 41 and one end connected to the screw for moving the movable member of the position limiter 43 by screwing the screw into or out of the screw hole enables the user to finely adjust the gap between the valve head 41 and the position limiter 43.
