Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, in particular to the technical field of bladder irrigation devices. Background Art

[0002] Bladder irrigation is a common operation in urology, mainly used to remove blood clots, pus, and exfoliated tissue fragments in the bladder to keep the urinary catheter unobstructed, prevent infection, and promote the recovery of bladder function. Traditional bladder irrigation devices usually consist of a flush solution container, a connecting tube, and a flush head. During operation, the flush solution needs to be first injected into the bladder and then drained from the bladder. For example, the bladder irrigation device with the publication number CN201921191U, the bladder irrigation device with the publication number CN201042530Y, and a bladder irrigation device with the publication number CN103520788A.

[0003] In actual clinical work, if the blood clots, pus, and exfoliated tissue fragments in the bladder are large and numerous, these substances may block the pipeline along with the flow of the flush solution. When encountering a blocked pipeline, doctors usually need to manually use a syringe for flushing, and sometimes even need to replace the urinary catheter (increasing the pain and treatment cost of the patient). This not only consumes a lot of energy, but also the open use of a syringe for flushing is very likely to cause urinary tract infections and liquid spillage (contaminating and wetting the bedsheet), thus resulting in a very poor experience for the patient.

[0004] In addition, traditional bladder irrigation devices usually use room-temperature flush solution (there may be a large temperature difference between the temperature of the flush solution and the human body temperature), which is likely to stimulate the bladder, causing discomfort symptoms such as bladder spasm and pain, and relatively affecting the comfort of the patient and the treatment effect. Summary of the Invention

[0005] The purpose of the present invention is to solve the problems in the prior art, and propose an anti-blocking bladder irrigation pump, which can perform bladder irrigation operations and pipeline blockage clearing operations respectively in the bladder irrigation mode and the pipeline blockage clearing mode. It is not only more labor-saving to use, but also not easy to cause urinary tract infections and wet the bedsheet, and can greatly improve the patient experience.

[0006] To achieve the above object, the present invention provides an anti-clogging bladder irrigation pump, which includes a catheter assembly, a liquid storage bag, a urinary catheter, a drainage bag, a suction pump and a controller. In the bladder irrigation mode, the liquid storage bag, the urinary catheter and the drainage bag are sequentially connected through the catheter assembly, so that the irrigation liquid first enters the bladder from the liquid storage bag through the urinary catheter under the action of gravity, and then enters the drainage bag from the bladder through the urinary catheter under the action of the pressure in the bladder, and finally completes the irrigation operation. In the pipeline clogging prevention mode, the liquid storage bag, the suction pump, the urinary catheter and the drainage bag are sequentially connected through the catheter assembly to use the suction pump to pump the irrigation liquid from the liquid storage bag through the urinary catheter into the bladder, and then from the bladder through the urinary catheter into the drainage bag, and finally complete the clogging prevention operation. The suction pump is electrically connected to the controller.

[0007] Preferably, the suction pump includes a pump housing, a cylinder, a solenoid valve and a piston. A transfer chamber is provided in the pump housing. The piston is driven by the cylinder to move in the transfer chamber, and the solenoid valve is installed at the outlet of the transfer chamber.

[0008] Preferably, the solenoid valve is provided with a first joint, a second joint and a third joint that can communicate the transfer chamber with the outside. The urinary catheter is in a Y shape. The catheter assembly has a first hose equipped with a speed regulator switch and a Murphy's dropper. The first hose branches at the bottom to form a first liquid outlet branch pipe and a second liquid outlet branch pipe. The first liquid outlet branch pipe is equipped with a hose clip and is connected to the urinary catheter from the first liquid inlet end. The second liquid outlet branch pipe is equipped with a hose clip and is connected to the solenoid valve from the first joint.

[0009] Preferably, in the bladder irrigation mode, the drainage bag connects its own second hose to the urinary catheter from the second liquid inlet end.

[0010] Preferably, the catheter assembly further includes a third hose. In the pipeline clogging prevention mode, one end of the third hose is connected to the urinary catheter from the second liquid inlet end, and the other end is connected to the solenoid valve from the second joint. In the pipeline clogging prevention mode, the drainage bag connects its own second hose to the solenoid valve from the third joint.

[0011] Preferably, a hose clip is installed on the second hose.

[0012] Preferably, the first hose branches at the top to form a plurality of liquid inlet branch pipes, and each liquid inlet branch pipe is respectively plugged into the corresponding liquid storage bag through a plug.

[0013] Preferably, a flow meter electrically connected to the controller is further installed on the first hose.

[0014] Preferably, a heating tape is further included. The heating tape is electrically connected to the controller and can be wrapped outside the liquid storage bag to perform external heating on the liquid storage bag.

[0015] Preferably, the heating belt includes a belt body, heating wires, a temperature sensor and a wire. The heating wires and the temperature sensor are respectively arranged in the belt body and connected to the controller through the wire. The two ends of the belt body are detachably connected by magic tapes.

[0016] Advantages of the present invention: 1) By combining a catheter assembly, a liquid storage bag, a urinary catheter, a drainage bag, a suction pump and a controller, an anti-blocking bladder irrigation pump with two working modes (i.e., bladder irrigation mode and pipeline blockage clearing mode) can be formed. Thus, on the one hand, when there is no tube blockage, the irrigation fluid first enters the bladder from the liquid storage bag through the urinary catheter under the action of gravity, and then enters the drainage bag from the bladder through the urinary catheter under the action of the bladder pressure, and finally completes the irrigation operation. On the other hand, when there is a tube blockage, the suction pump is used to pump the irrigation fluid from the liquid storage bag into the bladder through the urinary catheter first, and then pump it from the bladder into the drainage bag through the urinary catheter, which can replace manual irrigation of the pipeline and automatically complete the blockage clearing operation (reducing the workload of doctors). Moreover, the closed pipeline design is not easy to cause urinary tract infections and is not easy to contaminate the bed sheet, ultimately greatly improving the patient experience; 2) By installing a heating belt composed of a belt body, heating wires, a temperature sensor and a wire, the heating belt can be wrapped outside the liquid storage bag by magic tapes to externally heat the liquid storage bag, which can not only quickly and simply warm the irrigation fluid, but also adaptively wrap liquid storage bags of different sizes; 3) By making the first hose of the catheter assembly branch at the top to form a plurality of liquid inlet branch pipes, and each liquid inlet branch pipe is respectively plugged into the corresponding liquid storage bag, when the previous liquid storage bag is performing bladder irrigation operation or pipeline blockage clearing operation, the next liquid storage bag can complete the preheating work in advance, so that the bladder irrigation operation or pipeline blockage clearing operation can be carried out as continuously as possible.

Specific embodiments

[0020] Embodiment 1: Refer to Figures 1 to 5 , the anti - clogging bladder irrigation pump of the present invention includes a catheter assembly 1, a liquid storage bag 2, a urinary catheter 3, a drainage bag 4, a suction pump 5 and a controller 6. When in the bladder irrigation mode, the liquid storage bag 2, the urinary catheter 3 and the drainage bag 4 are sequentially connected through the catheter assembly 1 so that the irrigation liquid first enters the bladder from the liquid storage bag 2 through the urinary catheter 3 under the action of gravity, and then enters the drainage bag 4 from the bladder through the urinary catheter 3 under the action of the pressure in the bladder, and finally completes the irrigation operation. When in the pipeline clogging removal mode, the liquid storage bag 2, the suction pump 5, the urinary catheter 3 and the drainage bag 4 are sequentially connected through the catheter assembly 1 to use the suction pump 5 to pump the irrigation liquid from the liquid storage bag 2 through the urinary catheter 3 into the bladder first, and then pump it from the bladder through the urinary catheter 3 into the drainage bag 4, and finally complete the clogging removal operation. The suction pump 5 is electrically connected to the controller 6.

[0021] The suction pump 5 includes a pump housing 51, a cylinder 52, a solenoid valve 53 and a piston 54. A transfer chamber 511 is provided in the pump housing 51. The piston 54 is driven by the cylinder 52 to move in the transfer chamber 511. The solenoid valve 53 is installed at the outlet of the transfer chamber 511.

[0022] The solenoid valve 53 is provided with a first joint 531, a second joint 532 and a third joint 533 that can communicate the transfer chamber 511 with the outside. The urinary catheter 3 is in a Y - shape. The catheter assembly 1 has a first hose 11 equipped with a speed regulating switch 13 and a Murphy's dropper 14. The first hose 11 branches at the bottom to form a first liquid outlet branch pipe 111 and a second liquid outlet branch pipe 112. The first liquid outlet branch pipe 111 is equipped with a pipe clamp 15 and is connected to the urinary catheter 3 from the first liquid inlet end 31. The second liquid outlet branch pipe 112 is equipped with a pipe clamp 15 and is connected to the solenoid valve 53 from the first joint 531.

[0023] When the drainage bag 4 is in the bladder irrigation mode, the second hose 16 provided with the drainage bag 4 is connected to the urinary catheter 3 through the second liquid inlet end 32 .

[0024] The catheter assembly 1 also includes a third hose 17. In the pipeline clearing mode, one end of the third hose 17 is connected to the urinary catheter 3 through the second liquid inlet end 32 and the other end is connected to the solenoid valve 53 through the second connector 532. In the pipeline clearing mode, the drainage bag 4 connects its own second hose 16 to the solenoid valve 53 through the third connector 533.

[0025] A hose clamp 15 is mounted on the second hose 16 .

[0026] The first hose 11 branches out at the top to form a plurality of liquid inlet branches, and each liquid inlet branch is plugged into a corresponding liquid storage bag 2 via a plug 12 .

[0027] The device further comprises a heating belt 7 , which is electrically connected to the controller 6 and can be wrapped around the liquid storage bag 2 to externally heat the liquid storage bag 2 .

[0028] The heating belt 7 includes a belt body 71, a heating wire, a temperature sensor and an electric wire 72. The heating wire and the temperature sensor are respectively arranged in the belt body 71 and connected to the controller 6 through the electric wire 72. The two ends of the belt body 71 are detachably connected by Velcro 711.

[0029] Taking two liquid inlet branches as an example (a first liquid inlet branch on the left and a second liquid inlet branch on the right), the working process of the present invention is as follows: 1) When there is no blockage, use bladder irrigation mode (see Figure 1 ): First, the two heating belts 7 are wrapped around the two liquid storage bags 2 by using the Velcro 711, and then the two heating belts 7 are connected to the controller 6 by the wires 72, so that the two heating belts 7 preheat the wrapped two liquid storage bags 2 according to the preset temperature (input by the user in the controller 6); then, as shown in FIG. Figure 1Connect the pipelines as shown, open the pipe clamps 15 on the first liquid inlet branch pipe, the first liquid outlet branch pipe 111 and the second hose 16, close the pipe clamps 15 on the second liquid inlet branch pipe and the second liquid outlet branch pipe 112, and adjust the drip rate with the speed control switch 13, so that the flushing liquid first flows from the liquid storage bag 2 on the left side along the first liquid inlet branch pipe, the first liquid outlet branch pipe 111 and the urinary catheter 3 into the bladder in sequence, and then flows into the drainage bag 4 along the urinary catheter 3 and the second hose 16 in sequence; after the liquid storage bag 2 on the left side has released all the flushing liquid, open the pipe clamps 15 on the second liquid inlet branch pipe, the first liquid outlet branch pipe 111 and the second hose 16, close the pipe clamps 15 on the first liquid inlet branch pipe and the second liquid outlet branch pipe 112, so that the flushing liquid first flows from the liquid storage bag 2 on the right side along the second liquid inlet branch pipe, the first liquid outlet branch pipe 111 and the urinary catheter 3 into the bladder in sequence, and then flows into the drainage bag 4 along the urinary catheter 3 and the second hose 16 in sequence.

[0030] When a pipe blockage occurs (assuming that the liquid storage bag 2 on the left side has not released all the flushing liquid), use the pipe blockage clearing mode (refer to Figure 2 ): As Figure 2 shown, connect the pipelines, open the pipe clamps 15 on the first liquid inlet branch pipe, the second liquid outlet branch pipe 112 and the second hose 16, close the pipe clamps 15 on the second liquid inlet branch pipe and the first liquid outlet branch pipe 111, and set the suction times through the controller 5; during suction, first, the solenoid valve 53 only opens the first joint 531, and the air cylinder 52 pulls the piston 54 to move rightward, so that the flushing liquid flows from the liquid storage bag 2 on the left side along the first liquid inlet branch pipe and the second liquid outlet branch pipe 112 into the transfer chamber 511 in sequence; then, the solenoid valve 53 only opens the second joint 532, and the air cylinder 52 pushes the piston 54 to move leftward, so that the flushing liquid flows from the transfer chamber 511 along the third hose 17 and the urinary catheter 3 into the bladder in sequence; next, the solenoid valve 53 still only opens the second joint 532, and the air cylinder 52 pulls the piston 54 to move rightward, so that the flushing liquid flows from the bladder along the urinary catheter 3 and the third hose 17 into the transfer chamber 511 in sequence; then, the solenoid valve 53 only opens the third joint 533, and the air cylinder 52 pushes the piston 54 to move leftward, so that the flushing liquid flows from the transfer chamber 511 along the second hose 16 into the drainage bag 4; next, the suction pump 5 repeats the above suction process according to the set suction times.

[0031] Embodiment 2: Refer to Figures 1 to 5 , a flow meter 8 electrically connected to the controller 6 is further installed on the first hose 11; in addition, pipes can be additionally added and the flow meter 8 can be built into the controller 6.

[0032] Others are the same as in Embodiment 1.

[0033] In this embodiment, the flowmeter 8 can report the real-time flow rate changes to the controller 6 in the bladder irrigation mode, so as to realize the real-time monitoring of whether the tube is blocked.

[0034] The above embodiments are illustrative of the present invention and not restrictive thereof. Any solution obtained by simply transforming the present invention falls within the protection scope of the present invention.
