Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an isolation heating device and a water injection pump system with heating function. Background Technology

[0002] A water pump is an auxiliary device used in conjunction with surgical treatment. It flushes tissues by delivering water into the body, tubes, body cavities, or internal cavities to remove blood, excrement, and other organic matter, thereby improving the visibility of diagnosis and treatment during the procedure.

[0003] Currently, clinically used infusion pumps utilize peristaltic pumps to pressurize and deliver sterile fluids to the wound site for cleaning. In some surgeries, the injected sterile fluid needs to be close to the patient's body temperature; fluids at room temperature can cause muscle contractions, which is detrimental to the procedure.

[0004] Currently used endoscopic water delivery devices in clinical practice do not have heating functions. During surgery, sterile fluids need to be preheated in a water bath before being pumped in. The initial temperature of the hot water used in the water bath is difficult to control, and the temperature of the sterile fluid fluctuates as the water temperature decreases, which is not conducive to surgery.

[0005] Chinese patent document CN222102246U (202420718248.0) discloses a temperature-controlled animal peristaltic pump. It utilizes an extendable insulating heating device fitted to one end of a flexible tube to maintain a constant, specified temperature of the perfused solution as it enters the animal or organ. However, this peristaltic pump requires an external insulating heating device to heat the liquid inside the tube, placing specific requirements on the type and structure of this device, and thus not being compatible with all types of flexible tubes. Utility Model Content

[0006] The purpose of this invention is to design an isolation heating device and a water injection pump system with heating function. The heating device heats the flat heating part efficiently by utilizing the side wall of the heating chamber, which can meet the heating needs of different types of hoses and achieve constant temperature control of the liquid used for clinical surgical irrigation.

[0007] The technical problem to be solved by this utility model is achieved by the following technical solution: an isolation heating device, comprising a shell body and a heat-conducting pipe;

[0008] The heat pipe is provided with a flat heating section and liquid inlet and outlet located at both ends of the flat heating section. The width of the flat heating section is greater than the inner diameter of the liquid inlet and outlet, and the thickness of the flat heating section is less than the inner diameter of the liquid inlet and outlet.

[0009] A heating chamber is provided inside the housing body, and a heating device is provided on the side wall of the heating chamber. The side wall of the heating chamber is in contact with the outer surface of the flat heating part.

[0010] Preferably, this invention further includes a central support portion disposed within the housing body, the space between the central support portion and the inner cavity sidewall of the housing body forming a heating cavity. The central support portion within the housing body, and the space between the central support portion and the inner cavity sidewall of the housing body forming a heating cavity, facilitates the assembly of the heat-conducting pipe. The central support portion supports the heat-conducting pipe, ensuring that the outer surface of the heat-conducting pipe is in contact with the sidewall of the heating cavity.

[0011] Preferably, in this invention, a first heating device is provided on the inner wall of the shell body that contacts the flat heating part. The first heating device is disposed on the surface of the inner wall of the shell body or embedded in the shell body. By providing the first heating device on the inner wall of the shell body that contacts the flat heating part, the liquid in the heat-conducting pipe is heated by utilizing the inner wall of the shell body.

[0012] Preferably, a second heating device is provided within the central support portion of this invention. By providing the second heating device within the central support portion, the liquid inside the heat-conducting pipe is heated using the central support portion.

[0013] Preferably, in this invention, the central support is rotatably disposed within the housing body. The rotation of the central support heats the sidewall of the heat-conducting pipe, and the rotation of the central support vibrates the liquid inside the heat-conducting pipe, increasing the mixing of the liquid and ensuring uniform temperature throughout the liquid.

[0014] Preferably, this invention also includes a slip ring, through which the second heating device is connected to the power supply. The slip ring supplies power to the second heating device, ensuring continuous power supply to the second heating device during the rotation of the central support.

[0015] Preferably, the heat-conducting pipe of this invention is a flexible tube. A flexible heat-conducting pipe can be compressed to meet the spatial requirements of the heating chamber, facilitating installation and allowing the sidewall of the heat-conducting pipe to fit more tightly against the inner wall of the heating chamber, thus improving heat transfer efficiency.

[0016] Preferably, in this invention, the heat-conducting pipe is a metal pipe. Metal pipes have higher thermal conductivity, thus improving heating efficiency.

[0017] This utility model also discloses a water injection pump system with heating function, including the above-mentioned isolation heating device, and also includes a peristaltic pump and a water injection pump control system;

[0018] One of the liquid inlets and outlets of the heat pipe is connected to a peristaltic pump;

[0019] The water injection pump control system is used to control the operation of the peristaltic pump and the isolation heating device. The liquid is heated to a set temperature within the isolation heating device and then pumped into the body using the peristaltic pump, thus preventing bacterial infection.

[0020] Preferably, the present invention also includes a temperature sensor, and the water injection pump control system is provided with a control module;

[0021] The temperature sensor is used to detect the temperature of the sidewall of the heating chamber;

[0022] The temperature sensor and the heating device are electrically connected to the control module, respectively.

[0023] The control module controls the start and stop of the heating device based on the temperature detected by the temperature sensor. This water injection pump system uses a temperature sensor to detect the temperature of the side wall of the heating chamber, and the control module controls the start and stop of the heating device based on the temperature detected by the temperature sensor to achieve the preset temperature and realize constant temperature control.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows: The heat-conducting pipe of this utility model is provided with a flat heating part and liquid inlet and outlet located at both ends of the flat heating part. The width of the flat heating part is greater than the inner diameter of the liquid inlet and outlet, and the thickness of the flat heating part is less than the inner diameter of the liquid inlet and outlet. A heating cavity is provided inside the shell body, and a heating device is provided on the side wall of the heating cavity. Since the inner wall of the heating cavity is in contact with the side wall of the flat heating part, the liquid in the heat-conducting pipe is isolated and heated, which can be used for heating sterile liquids.

[0025] Because the heat pipe is equipped with a flat heating section, the liquid fed in through the liquid inlet and outlet is spread out for uniform heating, which increases the heat exchange area and effectively improves the heating efficiency, enabling the liquid to heat up rapidly within a short stroke.

[0038] The heat pipe 2 is a flexible tube. In this embodiment, the heat pipe 2 is a flat tube, specifically a widened silicone tube, which increases the heat exchange surface and improves heating efficiency.

[0039] The isolation heating device further includes a central support 3 disposed within the housing body 1, and the space between the central support 3 and the inner cavity sidewall of the housing body 1 forms a heating cavity 11.

[0040] The inner wall of the housing body 1 that contacts the flat heating part 21 is provided with a first heating device 4. The first heating device 4 is disposed on the inner wall surface of the housing body 1 or embedded in the housing body 1. In this embodiment, the first heating device 4 is an electric heating tube, which is embedded in the housing body 1 at intervals.

[0041] like Figure 3 and Figure 4 As shown, a water injection pump system with heating function also includes a peristaltic pump 7 and a water injection pump control system 8.

[0042] One of the liquid inlet / outlet 22 of the heat pipe 2 is connected to the peristaltic pump 7. The peristaltic pump 7 is responsible for pressurizing the sterile liquid in the accessory and pumping the sterile liquid into the endoscope according to the flow rate settings.

[0043] The water injection pump control system 8 is used to control the operation of the peristaltic pump 7 and the isolation heating device.

[0044] The water injection pump system with heating function also includes a temperature sensor 9, and the water injection pump control system 8 is equipped with a control module 81.

[0045] The temperature sensor 9 is used to detect the temperature of the sidewall of the heating chamber 11.

[0046] The temperature sensor 9 and the heating device are electrically connected to the control module 81.

[0047] The control module 81 controls the start and stop of the heating device based on the temperature detected by the temperature sensor 9.

[0048] like Figure 4 As shown, the water injection pump control system 8 also includes a rotary drive device 82, a liquid storage tank 83, a power supply module 84, and a display unit.

[0050] The rotary drive device 82 is connected to the peristaltic pump 7 and is used to drive the peristaltic pump 7 to rotate. The rotary drive device 82 is a motor.

[0051] The liquid storage tank 83 is connected to one of the liquid inlet / outlet 22 of the heat pipe 2 to provide sterile liquid. The inner diameter of the liquid inlet / outlet 22 of the heat pipe 2 is less than or equal to the inner diameter of the external pipe.

[0052] The control module 81 is the core control unit of the equipment, mainly responsible for logic control and constant temperature control of the heating unit. Its main functions include: displaying user parameters on the interface, controlling the speed and start / stop of the peristaltic pump 7, and handling system abnormal signals.
