Description

Technical Field

[0001] The invention relates to the field of flushing equipment, in particular to a bladder flushing equipment for urology. Background Art

[0002] Bladder irrigation refers to pouring a flushing fluid into the bladder to remove blood clots, mucus, bacteria and other foreign matter in the bladder and keep the urine drainage unobstructed. It can treat certain bladder diseases, such as cystitis and bladder tumors. In the prior art, the flushing fluid in the infusion bag is generally poured into the bladder through a hose. After the flushing fluid poured into the bladder enters the bladder, the bladder will reflexively contract the muscles and induce spasms due to its own disease factors and low temperature stimulation. The urine and flushing fluid in the bladder are squeezed back into the infusion bag along the hose, which contaminates the flushing fluid in the infusion bag and poses a risk of causing infection. At the same time, the existing equipment cannot promptly and effectively discharge the mixture of blood clots, mucus, bacteria and other foreign matter in the bladder and the flushing fluid. During the flushing process of the patient's bladder, it is easy to cause the patient's bladder to swell and increase the patient's pain.

[0003] Clinically, medical staff are required to adjust the flushing speed in time according to the color of the waste liquid, that is, faster if the color is darker and slower if the color is lighter. However, due to different knowledge levels and clinical experience, medical staff may have different judgments on the depth of the color of the waste liquid, resulting in uncertainty in medical and nursing measures. Inappropriate flushing speed may induce bladder spasms and urinary catheter blockage, causing great pain to patients. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a urological bladder flushing device which can timely and effectively discharge a mixture of foreign matter such as blood clots, mucus, bacteria and flushing fluid in the bladder during flushing of the patient's bladder.

[0005] In order to achieve the above object, the technical solution provided by the present invention is:

[0006] A bladder flushing device for urology comprises a lying plate, a flushing device is installed on one end of the lying plate in the length direction, a through hole is opened in the middle of the lying plate, a collecting box is arranged below the through hole, a diaphragm is fixedly and sealedly connected in the side of the through hole away from the flushing device, two cover plates are slidingly and sealedly connected in the through hole below the diaphragm, the two cover plates are symmetrically arranged, and the opposite end surfaces of the two cover plates are connected by an elastic film, a position adjustment component connected to the cover plates is arranged at the lower end of the lying plate, the position adjustment component comprises two adjustment arms, the two adjustment arms are respectively located below the two cover plates, the adjustment arm comprises a fixed seat fixed at the lower end of the lying plate, a second motor is fixed on the fixed seat, a connecting rod is fixed on the output shaft of the second motor, a first motor is fixed on the connecting rod, the output shaft of the first motor is perpendicular to the lying plate, a telescopic rod is concentrically fixed on the output shaft of the first motor, and the upper end of the telescopic rod is fixedly connected to the lower end of the cover plate.

[0007] Specifically, the flushing device includes a box body fixed on a lying board, a partition is fixed in the box body, the partition divides the box body into an independent flushing chamber and a waste liquid chamber, a flushing pump is fixed on the box body, the input pipe of the flushing pump is connected to the flushing chamber, and the output end of the flushing pump is connected to the output pipe; a waste liquid pump is fixed on the box body, the discharge pipe of the waste liquid pump is connected to the waste liquid chamber, the inlet end of the waste liquid pump is connected to the cannula, and the end of the output pipe away from the flushing pump passes through the side wall of one side of the cannula, enters the cannula, and passes out from the port of the cannula away from the waste liquid pump.

[0008] Specifically, a temperature sensor and a heating plate are fixed in the flushing cavity of the box body, and the temperature sensor and the heating plate are electrically connected to the controller.

[0009] Specifically, a liquid adding pipe communicating with the flushing cavity is fixed on the upper end of the box body, and the first cover body is connected to the liquid adding pipe; a liquid draining pipe communicating with the waste liquid cavity is fixed on the box body, and the second cover body is installed on the liquid draining pipe.

[0010] Specifically, a flow detection valve is installed on the discharge pipe, and the flow detection valve is electrically connected to the buzzer through a controller.

[0011] Specifically, a plurality of connecting strips are fixed to the outer edge of the output tube inside the cannula, and the connecting strips are fixedly connected to the inner edge of the cannula.

[0012] Specifically, a transparent window is provided on the side wall of the box body at one side of the waste liquid chamber, and a colorimetric card is fixed on the upper side of the transparent window.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The present invention fixes a colorimetric card on a transparent window, so that medical staff can observe the color of the liquid in the waste liquid chamber with the help of the colorimetric card and then select a suitable flushing speed.

[0015] 2. After the flushing fluid is discharged from the output tube, it is used to flush the patient's bladder. The mixed liquid in the patient's bladder can be discharged through the catheter. During the flushing of the patient's bladder, the mixture of foreign matter such as blood clots, mucus, bacteria and the flushing fluid in the bladder can be discharged promptly and effectively, which can avoid the patient's bladder from expanding and increasing pain.

[0016] 3. The cooperation of the electric heater, temperature sensor and controller can heat the flushing liquid in the flushing cavity at a constant temperature, avoiding irritation to the patient's bladder due to the low temperature of the flushing liquid during the flushing process, and reducing the patient's pain during the flushing process.

[0017] 4. By setting a flow detection valve, when the liquid flow discharged into the waste liquid chamber decreases abnormally, the controller can activate the buzzer alarm, thereby reminding medical staff that the flushing device is blocked, making it convenient for medical staff to remove the blockage in time.

[0018] 5. During the process of flushing the patient's bladder, part of the liquid flowing out of the catheter can be discharged to the lower side of the lying plate through the through hole. After the two cover plates rotate downward, the elastic film is flattened, thereby increasing the receiving area for the liquid. After the two cover plates and the elastic film rotate as a whole along the axis of the second motor, the inclined cover plates and the elastic film can guide the liquid discharged from the through hole to the collection box.

[0029] Embodiment 1:

[0030] like Figure 1-Figure 5 As shown, a bladder flushing device for urology includes a lying plate 1, and a flushing device is installed on one end of the lying plate 1 in the length direction. In this embodiment, the flushing device is located on the left side of the lying plate 1.

[0031] A through hole 2 is provided in the middle of the lying board 1 , and a collecting box 6 is provided below the through hole 2 .

[0032] A diaphragm 27 is fixedly and sealedly connected in the through hole 2 on one side away from the flushing device, and two cover plates 3 are slidingly and sealably connected in the through hole 2 below the diaphragm 27. The two cover plates 3 are symmetrically arranged front to back, and the opposite end surfaces of the two cover plates 3 are connected by an elastic film 12.

[0033] The lower end of the lying plate 1 is provided with a position adjustment component connected with the cover plate 3. The position adjustment component includes two adjustment arms, and the two adjustment arms are respectively located under the two cover plates 3.

[0034] The adjustment arm includes a fixing seat 9 fixed to the lower end of the lying plate 1, a second motor 11 is fixed to the fixing seat 9, a connecting rod 7 is fixed to the output shaft of the second motor 11, a first motor 10 is fixed to the connecting rod 7, and the output shaft of the first motor 10 is perpendicular to the lying plate 1. Specifically, the connecting rod 7 includes a straight portion and a vertical portion, and the straight portion and the vertical portion are fixedly connected. The upper end of the vertical portion of the connecting rod 7 is fixedly connected to the output shaft of the second motor 11, and the first motor 10 is fixed to the straight portion of the connecting rod 7.

[0035] A telescopic rod 8 is coaxially fixed to the output shaft of the first motor 10, and the upper end of the telescopic rod 8 is fixedly connected to the lower end of the cover plate 3. Specifically, the two adjacent corners of the two cover plates 3 below the diaphragm 27 are both processed with rounded corners, and the telescopic rod 8 is concentric with the rounded corner on one side thereof.

[0036] In this embodiment, the patient lies on the lying board 1 with the legs facing the flushing device. Then the two telescopic rods 8 are started, and the two telescopic rods 8 drive the two cover plates 3 to move downward in the through hole 2. When the two cover plates 3 withdraw from the through hole 2, the two first motors 10 are started, and the first motor 10 drives the telescopic rods 8 connected thereto to rotate. When the telescopic rods 8 rotate, the cover plates 3 connected to the telescopic rods 8 rotate, and the ends of the two cover plates 3 facing the flushing device move away from each other. The rounded corners on the cover plates 3 can make the two cover plates 3 rotate smoothly to prevent the two cover plates 3 from blocking each other when rotating. When the elastic film 12 is unfolded, the first motor 10 is turned off. Then the second motor 11 is started, and the second motor 11 drives the connecting rod 7, the first motor 10, the telescopic rod 8, the cover plate 3 and the elastic film 12 to rotate, and the cover plate 3 and the elastic film 12 are tilted downward toward one end of the flushing device. Subsequently, the liquid leaked during the flushing of the patient's bladder by the flushing device can flow to the bottom of the lying board 1 through the through hole 2, and the liquid flowing to the bottom of the lying board 1 flows into the collection box 6 under the diversion effect of the cover plate 3 and the film. By providing the partition, it can be ensured that all the liquid flowing down through the through hole 2 falls onto the cover plate 3 and the elastic film 12 .

[0037] After the patient's bladder is flushed, the cover plate 3 is restored, and after the cover plate 3 is restored, it enters into the through hole 2 and blocks the through hole 2. After the patient flushes the bladder, the patient can improve comfort when lying on the reclining board 1 to rest.

[0038] Embodiment 2:

[0039] Based on Example 1, refer to Figure 6-Figure 8 The flushing device includes a box body 4 fixed on the lying board 1, and a partition is fixed inside the box body 4, which divides the box body 4 into an independent flushing chamber and a waste liquid chamber. A liquid adding pipe 17 connected to the flushing chamber is fixed on the upper end of the box body 4, and a first cover body 16 is connected to the liquid adding pipe 17. A liquid drain pipe 21 connected to the waste liquid chamber is fixed on the box body 4, and a second cover body 22 is installed on the liquid drain pipe 21.

[0040] A temperature sensor 24 and a heating plate 23 are fixed in the flushing cavity of the box 4, and the temperature sensor 24 and the electric heating plate are electrically connected to the controller. The cooperation of the electric heating plate, the temperature sensor 24 and the controller can heat the flushing liquid in the flushing cavity at a constant temperature, thereby avoiding irritation of the patient's bladder due to the low temperature of the flushing liquid during the flushing process, and reducing the pain of the patient during the flushing process.

[0041] A flushing pump 13 is fixed on the box body 4 , an input pipe 25 of the flushing pump 13 is connected with the flushing cavity, and an output end of the flushing pump 13 is connected with an output pipe 14 .

[0042] A waste liquid pump 20 is fixed on the box body 4, the discharge pipe 18 of the waste liquid pump 20 is connected to the waste liquid cavity, the inlet end of the waste liquid pump 20 is connected to the cannula 5, and the end of the output pipe 14 away from the flushing pump 13 passes through the side wall of one side of the cannula 5, enters the cannula 5, and passes out from the port of the cannula 5 away from the waste liquid pump 20. Specifically, a plurality of connecting strips 26 are fixed to the outer edge of the output pipe 14 inside the cannula 5, and the connecting strips 26 are fixedly connected to the inner edge of the cannula 5.

[0043] When flushing the patient's bladder, the cannula 5 and the output tube 14 enter the patient's bladder through the urinary catheter, and the flushing pump 13 is started. The flushing pump 13 can discharge the flushing liquid in the flushing cavity through the output tube 14 into the patient's bladder and flush the patient's bladder. At the same time, the waste liquid pump 20 is started, and the liquid in the patient's bladder enters the waste liquid cavity through the cannula 5. The liquid in the patient's bladder can be discharged through the cannula 5. During the flushing of the patient's bladder, the mixture of foreign matter such as blood clots, mucus, bacteria and the flushing liquid in the bladder can be discharged in a timely and effective manner, which can prevent the patient's bladder from swelling and increasing pain.

[0044] The discharge pipe 18 is provided with a flow detection valve 15 , and the flow detection valve 15 is electrically connected to the buzzer through a controller.

[0045] During the process of flushing the bladder, by setting the flow detection valve 15, when the flow rate of the waste liquid discharge is abnormally reduced, the controller can start the buzzer alarm, thereby reminding the medical staff that the flushing device is blocked, so that the medical staff can remove the blockage in time.
