Description

Technical Field

[0001] The present invention relates to the technical field of bladder perfusion, and specifically to an internal bladder perfusion chemotherapy pump. Background Art

[0002] Bladder tumors are one of the most common tumors in the urinary system. In recent years, the incidence has been increasing year by year. Transurethral resection of bladder tumors is the preferred treatment method for non-muscle invasive bladder cancer. However, simple transurethral resection of bladder tumors cannot solve the problems of high recurrence and progression after surgery. Therefore, patients with non-muscle invasive bladder cancer are mostly recommended to undergo bladder perfusion treatment after surgery to reduce and delay tumor recurrence, prevent tumor invasion, and achieve a curative effect.

[0003] Bladder perfusion is a treatment method that directly injects drugs into the bladder using a catheter. It uses a perfusion chemotherapy pump as the power output to directly deliver the liquid medicine to the bladder mucosa, reducing side effects on other organs. The perfusion chemotherapy pump only has the functions of constant pressure and constant temperature to ensure the stability of the perfused liquid medicine. However, during actual operation, when the liquid medicine is perfused into the bladder, the perfusion chemotherapy pump stops delivering the liquid medicine. The liquid medicine in the bladder needs to be retained for 0.5 - 2 hours, or even longer. During this process, the patient needs to frequently change positions to ensure full contact between the liquid medicine and the lesion site. Also, since urine is continuously secreted during the retention time of the liquid medicine, the mixture of urine and the liquid medicine reduces the concentration of the liquid medicine, which may affect the treatment effect. Therefore, an internal bladder perfusion chemotherapy pump is proposed to address the above problems. Summary of the Invention

[0004] The purpose of the present invention is to provide an internal bladder perfusion chemotherapy pump to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] As an optional solution of an internal bladder perfusion chemotherapy pump according to the present invention, wherein: an internal bladder perfusion chemotherapy pump includes a perfusion module, a liquid medicine delivery module, and an insertion module;

[0007] One side of the perfusion module is connected to the liquid medicine delivery module, and one side of the liquid medicine delivery module is equipped with an insertion module for inserting into the patient's body;

[0008] An initial perfusion heating module for controlling the temperature of the liquid medicine inside the liquid medicine delivery module is further installed outside the liquid medicine delivery module. One side of the initial perfusion heating module is provided with a manual infusion module for supplementing the liquid medicine inside the liquid medicine delivery module, and one side of the manual infusion module is connected to the perfusion module. The other side of the initial perfusion heating module is also provided with an end fixing module fixedly connected to the liquid medicine delivery module;

[0009] The liquid medicine delivery module includes an infusion pipeline, a liquid inlet pipeline, and a liquid discharge pipeline. One side of the infusion pipeline is communicated with the perfusion module. A manual infusion module, a head fixing module, and an initial perfusion heating module are also installed outside the infusion pipeline. The liquid inlet pipeline and the liquid discharge pipeline are arranged inside the infusion pipeline. One side of the infusion pipeline is communicated with an insertion module. One end of the liquid discharge pipeline is communicated with a return pipe, and the other side of the return pipe is communicated with a back suction pump.

[0012] As an alternative solution of the built-in bladder perfusion chemotherapy pump of the present invention, wherein: the root of the connecting shaft is provided with an elastic member and is fixedly connected to the fixing ring.

[0013] Bladder instillation is a treatment method that uses a catheter to directly inject drugs into the bladder. It uses an instillation chemotherapy pump as a power output to deliver the drug solution directly to the bladder mucosa to reduce side effects on other organs. The instillation chemotherapy pump only has the functions of constant pressure and constant temperature to ensure the stability of the instilled drug solution. However, in actual operation, the drug solution is instilled into the bladder and the instillation chemotherapy pump stops delivering the drug solution. The drug solution in the bladder needs to be retained for 0.5-2 hours. During this process, the patient needs to change his position frequently to ensure that the drug solution is in full contact with the lesion site. In addition, during the residence time of the drug solution, the urine is continuously secreted, and the urine mixes with the drug solution to reduce the concentration of the drug solution, which may affect the treatment effect. At the same time, the method of injecting drugs into the bladder through a catheter at one time is generally not easy to move. At this time, the position of the drug attachment to the bladder may be inaccurate, and the chemotherapy drug cannot fully contact the lesion site, resulting in poor treatment effect. When this device is used, The infusion pipeline is provided with an inlet pipeline and a discharge pipeline. The inlet pipeline is used for delivering the medicine. After the urine is continuously secreted in the bladder, the pressure on the bladder is increased, and the concentration of the medicine is continuously diluted. At this time, the return pump is started to slowly extract the mixed liquid in the bladder through the discharge pipeline and the reflux pipe. On the one hand, the pressure of the medicine and urine on the bladder is reduced. On the other hand, the concentration of the medicine can be detected by the medicine concentration detector. When the concentration is reduced, the perfusion module can continue to perfuse the bladder with medicine to ensure the concentration of the medicine and the treatment effect. A fixing ring is provided at one end of the medicine delivery module, and the connecting belt can be fixed at the base of the patient's leg and fixed by Velcro. It is then connected to the threaded shaft through a threaded sleeve. At this time, it is used to fix the end of the medicine delivery module to avoid discomfort to the patient when the pipeline moves, and to ensure that the insertion module is not easily displaced by the dislocation, movement, shaking or pulling of the medicine delivery module.

[0014] As an optional solution of the built-in bladder infusion chemotherapy pump described in the present invention, the infusion module includes an infusion pump, a constant temperature mechanism and a constant pressure mechanism, one side of the infusion pump is connected to the drug delivery module, the outer side of the infusion pump is connected to the manual infusion module, and the top of the infusion pump is equipped with a constant temperature mechanism and a constant pressure mechanism.

[0015] As an optional solution of the internal bladder infusion chemotherapy pump described in the present invention, the insertion module includes an insertion tube, a rotating sleeve and a rotating ring, one end of the insertion tube is connected to the drug delivery module, the outer side of the insertion tube is rotatably connected to the rotating ring, one side of the rotating ring is also fixedly connected to the rotating sleeve, and the inner side of the rotating sleeve is fixedly connected to the insertion tube.

[0016] As an optional solution of the internal bladder infusion chemotherapy pump described in the present invention, the inner side of the insertion tube is provided with two chambers, and the rotating sleeve is made of soft rubber block material.

[0017] When the liquid medicine is transported inside the insertion tube, it can drive the rotating sleeve to rotate by rotating the rotating ring. At this time, the insertion tube can be driven to change in a certain direction to ensure that the liquid medicine contacts the lesion to achieve a better treatment effect.

[0018] As an alternative solution of the built-in bladder perfusion chemotherapy pump described in the present invention, wherein: the manual infusion module includes an empty cylinder, a squeezing piston and a first communication pipe. One end of the empty cylinder is communicated with the first communication pipe. One side of the first communication pipe is communicated with the liquid medicine delivery module. The side of the empty cylinder is communicated with a second communication pipe. The other end of the second communication pipe is communicated with the perfusion module. A first one-way valve and a second one-way valve are respectively installed outside the first communication pipe and the second communication pipe. A squeezing piston is also installed inside the empty cylinder, and a limiting block is installed inside the empty cylinder.

[0019] During the actual use process, once the perfusion module is damaged, at this time, the empty cylinder is docked with the first communication pipe, the side of the empty cylinder is docked with the second communication pipe, and the squeezing piston is slowly pushed to realize the perfusion of the liquid medicine inside the empty cylinder, achieving the purpose of manual perfusion and ensuring the normal progress of the perfusion work.

[0020] As an alternative solution of the built-in bladder perfusion chemotherapy pump described in the present invention, wherein: the initial perfusion heating module includes a mounting frame, a circulation pump and a heating spiral tube. The circulation pump is installed inside the mounting frame. The output end of the circulation pump is communicated with the heating spiral tube. The inner side of the heating spiral tube contacts the liquid medicine delivery module. A temperature control tube is fixedly connected to the outer side of the heating spiral tube. The other side of the heating spiral tube is communicated with the mounting frame, and a heating plate is also installed inside the mounting frame.

[0021] As an alternative solution of the built-in bladder perfusion chemotherapy pump described in the present invention, wherein: a cooling pump is further arranged on the outer side of the temperature control tube, and the output end of the cooling pump is communicated with a cooling tube, and the other end of the cooling tube is communicated with an output tube. A first temperature sensor and a second temperature sensor are also installed on the outer side of the temperature control tube.

[0022] As an alternative solution of the built-in bladder perfusion chemotherapy pump described in the present invention, wherein: an external ring sleeved on the outer side of the liquid medicine delivery module is further arranged on one side of the temperature control tube, and a third temperature sensor is installed on the outer side of the external ring.

[0023] In the early stage of perfusion, although the perfusion module is designed to warm the liquid medicine, as the warmed liquid medicine gradually flows through the liquid inlet pipe inside the infusion pipe, heat exchange occurs at this time. Generally, the temperature of the liquid medicine injected into the bladder in the early stage will decrease, causing discomfort to the patient. At this time, an initial perfusion heating module is provided at one end of the liquid medicine delivery module. The temperature of the liquid medicine is detected in advance by the third temperature sensor, and then the circulating liquid is heated by the heating plate and then discharged into the heating spiral pipe through the circulating pump. At this time, the liquid medicine can be reheated to ensure that the patient is in a comfortable environment.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] When the present invention is in use, a liquid inlet pipe and a liquid discharge pipe are arranged inside the infusion pipe. The liquid inlet pipe is used for transporting the liquid medicine. After the urine in the bladder is continuously secreted, the pressure on the bladder increases, and the concentration of the liquid medicine is continuously diluted. At this time, the back-pumping pump is started, and the mixed liquid in the bladder can be slowly pumped out through the liquid discharge pipe and the return pipe. On the one hand, the pressure of the liquid medicine and urine on the bladder is reduced. On the other hand, the concentration of the liquid medicine can be detected by the liquid medicine concentration detector. When the concentration decreases, the perfusion module can continuously perfuse the liquid medicine into the bladder to ensure the concentration of the liquid medicine and guarantee the treatment effect.

[0026] A fixing ring is provided at one end of the liquid medicine delivery module, and the connecting belt can be fixed to the root of the patient's leg and fixed by Velcro. Then it is connected to the threaded shaft through the threaded sleeve. At this time, it is used to fix the end of the liquid medicine delivery module, avoiding discomfort to the patient caused by the movement of the pipe, and ensuring that the insertion module part is not easily displaced due to misalignment, movement, shaking or pulling of the liquid medicine delivery module.

[0027] When the liquid medicine is transported inside the insertion tube, the rotating sleeve can be driven to rotate by rotating the rotating ring. At this time, the insertion tube can be driven to change in a certain direction to ensure that the liquid medicine contacts the lesion to achieve a better treatment effect.

[0028] During the actual use process, once the perfusion module is damaged, at this time, the empty cylinder is docked with the first connecting pipe, and the side of the empty cylinder is docked with the second connecting pipe. Slowly pushing the extrusion piston can realize the perfusion of the liquid medicine inside the empty cylinder, with the purpose of manual perfusion to ensure the normal progress of the perfusion work.

[0029] In the early stage of perfusion, although the perfusion module aims to warm the liquid medicine, as the warmed liquid medicine gradually flows through the liquid inlet pipe inside the infusion pipe, heat exchange occurs at this time. Generally, the temperature of the liquid medicine injected into the bladder in the early stage will decrease, causing discomfort to the patient. At this time, an initial perfusion heating module is provided at one end of the liquid medicine delivery module. The temperature of the liquid medicine is detected in advance by the third temperature sensor, and then the circulating liquid is heated by the heating plate and then discharged into the heating spiral pipe by the circulating pump. At this time, the liquid medicine can be reheated to ensure that the patient is in a comfortable environment;

[0030] During the heating process of the heating spiral pipe, once the situation of overheating occurs, at this time, the cooling pump can drive the external cooling liquid into the cooling pipe, and at this time, the overheated liquid medicine can be further cooled to ensure that the liquid medicine is at a suitable temperature for perfusion work.

One side of the above-mentioned infusion pipeline 201 is communicated with the perfusion module 1. A manual infusion module 4, a head fixing module 5, and an initial perfusion heating module 6 are also installed outside the above-mentioned infusion pipeline 201. The liquid inlet pipeline 202 and the liquid discharge pipeline 203 are arranged inside the above-mentioned infusion pipeline 201. One side of the above-mentioned infusion pipeline 201 is communicated with an insertion module 3. One end of the above-mentioned liquid discharge pipeline 203 is communicated with a return pipe 204. The other side of the above-mentioned return pipe 204 is communicated with a back suction pump 205. A liquid medicine concentration detector 206 for detecting the concentration of the liquid medicine is installed outside the above-mentioned back suction pump 205;

[0043] The above-mentioned head fixing module 5 includes a fixing ring 501, a connecting shaft 502, and a threaded sleeve 503. The inside of the above-mentioned fixing ring 501 is fixedly connected to the liquid medicine delivery module 2. A connecting shaft 502 is fixedly connected to the outside of the above-mentioned fixing ring 501. The other end of the above-mentioned connecting shaft 502 is rotatably connected to a threaded sleeve 503. A threaded shaft 504 is helically connected inside the above-mentioned threaded sleeve 503.

[0044] The inner side of the above-mentioned support member 507 is arranged in an arc shape.

[0045] The root of the above-mentioned connecting shaft 502 is provided with an elastic member and is fixedly connected to the fixing ring 501.

[0046] Bladder perfusion is a treatment method that directly injects drugs into the bladder using a catheter. It uses a perfusion chemotherapy pump as the power output to directly deliver the liquid medicine to the bladder mucosa, reducing side effects on other organs. The perfusion chemotherapy pump only has the functions of constant pressure and constant temperature to ensure the stability of the perfused liquid medicine. However, during actual operation, when the liquid medicine is perfused into the bladder, the perfusion chemotherapy pump stops delivering the liquid medicine. The liquid medicine in the bladder needs to be retained for 0.5 - 2 hours. During this process, the patient needs to frequently change positions to ensure that the liquid medicine is in full contact with the diseased area. Also, since urine is continuously secreted during the retention time of the liquid medicine, the mixture of urine and the liquid medicine reduces the concentration of the liquid medicine, which may affect the treatment effect. At the same time, through the method of injecting the liquid medicine into the bladder once through the catheter, the catheter is generally not easy to move. At this time, it may cause the position of the drug attached to the bladder to be inaccurate, and the chemotherapy drug cannot be in full contact with the diseased area, resulting in a somewhat poor treatment effect. When this device is in use, an inlet pipe 202 and a drain pipe 203 are arranged inside the infusion pipeline 201. The inlet pipe 202 is used for delivering the liquid medicine. After urine is continuously secreted in the bladder, it increases the pressure on the bladder, and the concentration of the liquid medicine is continuously diluted. At this time, by starting the back-pump 205, the mixture in the bladder can be slowly drawn out through the drain pipe 203 and the return pipe 204. On the one hand, it reduces the pressure of the liquid medicine and urine on the bladder. On the other hand, the concentration of the liquid medicine can be detected by the liquid medicine concentration detector 206. When its concentration decreases, the perfusion module 1 can continuously perfuse the liquid medicine into the bladder to ensure the concentration of the liquid medicine and guarantee the treatment effect. One end of the liquid medicine delivery module 2 is provided with a fixing ring 501, and the connecting belt 505 can be fixed to the patient's thigh root and fixed by the magic tape 506. Then it is connected to the threaded shaft 504 through the threaded sleeve 503. At this time, it is used to fix the end of the liquid medicine delivery module 2 to avoid causing discomfort to the patient when the pipeline moves, and it can ensure that the insertion module 3 is not easily displaced due to misalignment, movement, shaking or pulling of the liquid medicine delivery module 2;

[0047] In this embodiment, the inlet pipe 202 and the drain pipe 203 are separated, and the liquid delivery will not cause mutual influence. The infusion pipeline 201 is made of a rubber hose and can be bent. The outer side of the infusion pipeline 201 is also equipped with an end fixing module 5 to prevent the insertion module 3 from being affected when the patient changes positions. When a problem occurs with the perfusion module 1 during use, manual infusion can be carried out through the manual infusion module 4 to ensure the normal progress of the infusion work. The initial perfusion heating module 6 can ensure the temperature of the liquid medicine during the initial perfusion and avoid causing discomfort to the patient;

[0048] When the end fixing module 5 is fixed to the patient's leg, the support member 507 provided thereon is flush with the direction of the leg. At this time, the connecting belt 505 can be further fixed to achieve a certain reinforcement purpose. The root of the connecting shaft 502 is made of an elastic material and has a certain buffering function. The setting of the end fixing module 5 can limit the insertion module 3 from being driven by the liquid medicine delivery module 2 and ensure the fixed position of the insertion module 3.

[0049] Embodiment 2: This embodiment is an improvement on Embodiment 1. Please refer to Figure 1 and Figure 3 , specifically, the above-mentioned perfusion module 1 includes a perfusion pump 101, a constant temperature mechanism 102 and a constant pressure mechanism 103.

The side of the empty cylinder 401 is connected to a second connecting pipe 405. The other end of the second connecting pipe 405 is connected to the perfusion module 1. First check valves 404 and second check valves 406 are respectively installed on the outer sides of the first connecting pipe 403 and the second connecting pipe 405. A squeezing piston 402 is also installed inside the empty cylinder 401, and a limiting block 407 is installed inside the empty cylinder 401.

[0056] In this embodiment, the second connecting pipe 405 is connected to the output end of the constant temperature mechanism 102 of the perfusion module 1. At this time, the temperature of the output liquid medicine can be guaranteed. The first check valve 404 and the second check valve 406 are provided to ensure the one-way flow of the liquid medicine. When the squeezing piston 402 is pushed, the delivery of the liquid medicine is realized. When the squeezing piston 402 is pulled outward, it can realize the replenishment of the liquid medicine. The provided limiting block 407 can prevent the squeezing piston 402 from being overly squeezed, ensuring that the squeezing piston 402 cannot be squeezed to the bottom. At this time, the stable delivery of the liquid medicine can be ensured, preventing air from entering it. One end of the first connecting pipe 403 is connected to the liquid inlet pipe 202 to realize the stable delivery of the liquid medicine.

A first temperature sensor 608 and a second temperature sensor 609 are also installed on the outer side of the temperature control tube 605.

[0059] On one side of the temperature control tube 605 described above, there is also an external ring 610 sleeved outside the liquid medicine delivery module 2, and a third temperature sensor 611 is installed on the outside of the external ring 610.

[0060] In the early stage of perfusion, although the perfusion module 1 is intended to warm the liquid medicine, as the warmed liquid medicine gradually flows through the liquid inlet pipe 202 inside the infusion pipe 201, heat exchange occurs at this time. Generally, the temperature of the liquid medicine injected into the bladder in the early stage will decrease, causing discomfort to the patient when it is delivered to the inside of the bladder. At this time, an initial perfusion heating module 6 is provided at one end of the liquid medicine delivery module 2.
