Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a bladder flushing device. Background Art

[0002] A urinary catheter is a tube that is inserted into the bladder through the urethra to drain urine. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride and can be inserted into the bladder through the urethra to drain urine. In clinical nursing work, in addition to strengthening the care of indwelling urinary catheters and keeping the urethra unobstructed, most nursing content also includes flushing the bladder of indwelling patients. Bladder irrigation is a method of using a urinary catheter to inject a solution into the bladder and then use the siphon principle to drain the injected liquid out. The purpose of bladder irrigation is: to maintain unobstructed urine drainage for patients with indwelling urinary catheters; to remove blood clots, mucus, bacteria and other foreign matter in the bladder; and to treat certain bladder diseases, such as cystitis and bladder tumors.

[0003] However, current bladder irrigation devices have the following problems during the irrigation process:

[0004] (1) In order to prevent a large amount of room-temperature liquid from entering the patient's bladder and causing bladder disease, especially in autumn and winter, even a large amount of irrigation liquid at room temperature entering the patient's bladder will cause bladder spasm and even aggravate bladder bleeding. Most current irrigation devices use a heater wrapped around the catheter to heat the liquid in the irrigation pipe. However, the pipe covered by the heater is only a partially straight pipe. When the liquid flow rate is fast, it is difficult to ensure uniform constant temperature heating and it is impossible to maintain the appropriate temperature of the liquid, which will still cause discomfort to the patient.

[0005] (2) For a hanging type flushing device, in order to ensure the flow rate of the flushing liquid, it needs to be hung at a higher position. However, when it is hung at a higher position, it will cause inconvenience to medical staff or family members when operating the device or observing the remaining amount of liquid in the bag. Utility Model Content

[0006] In order to solve the above technical problems, the utility model designs a bladder irrigation device, which can increase the length of the liquid flowing through the heater and the heating time, and can maintain the liquid at an appropriate temperature even if the liquid flow rate is fast, thereby improving the patient's comfort. In addition, the device only needs to be hung at a position higher than the human body to have a faster flow rate, which is more conducive to observing or operating the device.

[0007] In order to achieve the above technical purpose, the utility model is realized by the following technical solutions: a bladder irrigation device, comprising an irrigation bag with a hook on the top, a medicine bag, a catheter, a heater, and a drainage bag;

[0008] The top of the flushing bag and the liquid medicine bag are connected to the exhaust pipe, and the bottom is connected to the head end of the main pipe through a connecting branch pipe, and a clamp is also provided outside the connecting branch pipe;

[0009] The middle of the main conduit is connected to a heater, and a conical spiral heating tube is arranged inside the heater;

[0010] The end of the main pipe is connected to the flushing branch pipe and the drainage branch pipe, and a downstream one-way valve is provided at the end of the main pipe;

[0011] The end of the drainage branch tube is connected to a drainage bag, and a clamp is provided on the drainage branch tube.

[0012] Preferably, a filter is provided inside the exhaust pipe, and a sealing cap is detachably connected to the top of the exhaust pipe.

[0013] Preferably, a downstream one-way valve is respectively provided in the connecting branch pipes.

[0014] Preferably, a flow regulator is provided on the flushing branch pipe, and a connector for connecting to the indwelling urinary catheter is provided at the end of the flushing branch pipe.

[0015] Preferably, the drainage branch tube is further connected to a suction branch tube at the lower portion of the clamp, and a rubber plug is provided at the end of the suction branch tube for sealing.

[0016] Preferably, the tops of the flushing bag and the medicine bag are also provided with liquid injection ports.

[0017] The beneficial effects of the utility model are:

[0018] (1) During the flushing process, the conical spiral heating tube inside the heater connected to the main conduit heats the liquid flowing through it. Under the action of the spiral, the length of the liquid flowing through the heater is increased, which increases the heating time. Even if the liquid flow rate is fast, the liquid can be maintained at an appropriate temperature, thereby improving the patient's comfort.

[0019] (2) Under the action of the ventilation and pressurization of the exhaust pipes of the flushing bag and the liquid medicine bag and the vortex flow channel of the conical spiral heating tube, the device only needs to be hung above the patient's body surface to have a faster flow rate, which is more conducive to observing or operating the device. The atmospheric pressure on the inside of the flushing bag and the liquid medicine bag can be controlled by controlling the opening and closing of the exhaust pipe, thereby controlling the flow rate.

DETAILED DESCRIPTION

[0024] The following is a further description of specific embodiments of the present invention. It should be noted that the description of these embodiments is intended to facilitate understanding of the present invention and does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0025] Example 1

[0026] In order to solve the problem that most current irrigation devices cover the catheter with a heater to heat the liquid in the irrigation pipe, but the pipe covered by the heater is only partially straight, and it is difficult to ensure uniform constant temperature heating when the liquid flow rate is fast, and it is impossible to maintain the appropriate temperature of the liquid, which will still cause discomfort to the patient. Figure 1 As shown, a bladder irrigation device is proposed, comprising an irrigation bag 1 with a hook 102 on the top, a liquid medicine bag 2, a catheter, a heater 7, and a drainage bag 12;

[0027] The flushing bag 1 and the medicine bag 2 are hung on a conventional infusion stand through a hook 102. The bottoms of the flushing bag 1 and the medicine bag 2 are respectively connected to the head end of the main conduit 6 through a connecting branch pipe 3. The medicine inside the flushing bag 1 and the medicine bag 2 eventually flows down to the flushing branch pipe 8 through the main conduit 6. A clamp 4 is also provided outside the connecting branch pipe 3. The clamp 4 controls the liquid in the flushing bag 1 and the medicine bag 2 to flow down to the main conduit 6, so that the required liquid can be flexibly controlled to flow into the main conduit 6.

[0028] In order to prevent the liquids in the flushing bag 1 and the medicine bag 2 from flowing into the bag body through the connecting branch 3 and mixing, a downstream one-way valve 5 is provided in the connecting branch 3, so that the liquid can only flow downward in one direction to avoid flowing into the bag body and mixing.

[0029] At the same time, in order to quickly add liquid to the flushing bag 1 and the medicine bag 2 after flushing, a liquid injection port 101 is provided on the top of the flushing bag 1 and the medicine bag 2, through which flushing liquid or medicine can be quickly added.

[0030] A heater 7 is connected to the middle of the main conduit 6 to heat the liquid flowing through the main conduit 6 during flushing. A conical spiral heating tube 701 is set inside the heater 7. Under the action of the spiral, the length of the liquid flowing through the heater 7 is increased, and the heating time is increased. Even if the liquid flow rate is fast, the liquid can be maintained at an appropriate temperature, thereby improving the patient's comfort.

[0031] The end of the main conduit 6 is connected to the flushing branch 8 and the drainage branch 11, and a downstream one-way valve 5 is provided at the end of the main conduit 6 to prevent the drainage waste liquid from flowing back and contaminating the main conduit 6;

[0032] The flushing branch tube 8 is connected to the indwelling urinary catheter for flushing the bladder, and the drainage branch tube 11 is connected to the flushing branch tube 8 to drain the flushing waste liquid after flushing. The end of the drainage branch tube 11 is connected to the drainage bag 12, and a clamp 4 is set on the drainage branch tube 11. The clamp 4 can clamp the drainage branch tube 11 during the flushing stage to prevent the liquid medicine from directly flowing into the drainage bag 12 and causing waste.

[0033] In order to control the flushing flow and flow rate of the flushing liquid, as well as the drainage speed and pressure of the flushing waste liquid, a flow regulator 9 is set on the flushing branch pipe 8. The flow regulator 9 adjusts and controls the flow, flow rate and drainage pressure during drainage to avoid excessive drainage speed or pressure, which may cause bladder damage. A connector 10 connected to the indwelling urinary catheter is set at the end of the flushing branch pipe 8.

[0034] In order to make the drainage of flushing waste liquid after bladder flushing faster and smoother, and to avoid the reduction of drainage efficiency caused by excessive pressure in the drainage bag 12, the drainage branch tube 11 is also connected to a suction branch tube 13 at the lower part of the clamp 4. A rubber plug 1301 is provided at the end of the suction branch tube 13 for sealing. A syringe is inserted into the rubber plug 1301 for suction, so that the waste liquid in the bladder enters the drainage branch tube 11 through the flushing branch tube 8 and finally enters the drainage bag 12. During suction, the air pressure in the drainage bag 12 can be reduced, which is more conducive to the inflow of drainage liquid.

[0035] Example 2

[0036] In order to solve the problem that the hanging flushing device needs to be hung at a higher position to ensure the flow rate of the flushing liquid, but when it is hung at a higher position, it will cause inconvenience to medical staff or family members when operating the device or observing the remaining liquid in the bag. On the basis of Example 1, an exhaust pipe 14 is connected to the top of the flushing bag 1 and the medicine liquid bag 2. The vertical air pressure of the liquid inside the flushing bag 1 and the medicine liquid bag 2 is increased through the exhaust pipe 14, thereby accelerating the flow rate; a filter 1401 is also provided inside the exhaust pipe 14 to prevent pollutants from entering the pipeline. The top of the exhaust pipe 14 is threadedly connected to a sealing cap 1402. When the hanging height is high, there is no need to increase the pressure to accelerate the flow rate, and the sealing cap 1402 is used for sealing.

[0037] Under the action of the ventilation and pressurization of the exhaust pipe 14 of the flushing bag 1 and the drug solution bag 2 and the vortex flow path of the conical spiral heating tube 701 in Example 1, the device only needs to be hung above the patient's body surface to have a faster flow rate, which is more conducive to observing or operating the device. In addition, the atmospheric pressure on the inside of the flushing bag 1 and the drug solution bag 2 can be controlled by controlling the opening and closing of the exhaust pipe 14, thereby controlling the flow rate.
