Description

Technical Field

[0001] The present application relates to the technical field of blood treatment equipment, and in particular to a temperature controller for blood treatment equipment and blood treatment equipment. Background Art

[0002] Some medical equipment requires heating of liquids, such as hemodialysis equipment, continuous blood purification equipment (CRRT, Continuous Renal Replacement Therapy, continuous renal replacement therapy) and other blood treatment equipment. It is necessary to heat the dialysate that circulates with human blood or the plasma that needs to be transfused into the human body to prevent continuous large amounts of external low-temperature liquid (usually refrigerated liquid) from flowing into the human body and causing discomfort. The liquid is usually heated to a temperature range close to human body temperature, such as 37°C, so the liquid temperature also needs to be controlled to prevent insufficient temperature or overheating. However, since it takes a certain amount of time for the sensor to sense the temperature and it is usually located at the outlet of the heating chamber, and the controller controls the heater that heats the liquid to turn off according to the sensor detection value, if the sensor response time is long, the actual heating temperature in the heating chamber will be higher than the measured temperature, which will further cause overheated liquid to flow into the human body and cause discomfort or accidents. Furthermore, if the sensor isn't precise enough to accurately sense temperature, the controller's adjustments to the heater that heats the liquid based on the sensor's readings could easily lead to misadjustments, resulting in inaccurate temperature control. This could cause insufficient or overheated liquid to flow into the body, causing discomfort or accidents. Therefore, improving the thermostat's response speed and temperature control accuracy is crucial. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0025] Please refer to the attached Figure 1-Figure 2 , an embodiment of the present application provides a temperature controller on a blood treatment device for monitoring the temperature of liquids such as liquid medicine or plasma. The temperature controller includes a first temperature measuring element 2 and a second temperature measuring element 3 for measuring the temperature of the liquid medicine. The first temperature measuring element 2 and the second temperature measuring element 3 are of different types, and the first temperature measuring element 2 is an infrared temperature sensor 2a. Then, the temperature controller has two types of temperature measuring elements, one of which is an infrared temperature sensor 2a. The infrared temperature sensor 2a has fast temperature measurement and fast response. It can quickly measure the liquid temperature and feed it back to the controller, so that the controller can quickly adjust the power of the heating element and improve the response speed. The other type of temperature measuring element can use a higher-precision sensor, such as a thermocouple temperature sensor, a semiconductor temperature sensor, or a platinum resistance temperature sensor, etc., to provide more accurate measurement data, so that the controller can shut down the heating element at the appropriate time, and ultimately control the liquid medicine temperature at a preset value. In this way, the two types of sensors are used in combination, and the controller can quickly adjust the power of the heater according to the data of the infrared temperature sensor 2a. For example, when approaching the target temperature value, the power of the heater is quickly reduced according to the rapid feedback of the infrared temperature sensor 2a, and then the power is comprehensively and accurately adjusted according to the data of another type of sensor with higher accuracy or the data of the two types of sensors, accurately shutting down the heating element, and accurately controlling the actual heating temperature of the liquid.

[0026] It can be seen that the temperature controller provided by the present application has fast temperature measurement, fast response, and accurate temperature measurement. It can not only quickly measure the liquid temperature and feed it back to the controller, thereby improving the response speed to facilitate rapid regulation of the controller, but also provide accurate temperature measurement data, which is conducive to accurate temperature control of the controller. Thus, the overall temperature control accuracy can be improved, which is conducive to more accurate control of the liquid temperature. It is especially suitable for use in blood treatment equipment. For long-term continuous input of medicinal liquids into the human body, more accurate temperature control can be performed, which can reduce human discomfort and alleviate treatment discomfort.

[0027] Specifically, the second temperature measuring element 3 can be any one of a thermocouple temperature sensor, a semiconductor temperature sensor or a platinum resistance temperature sensor. In a preferred embodiment, the second temperature measuring element 3 is a platinum resistance temperature sensor, such as PT1000. This type of temperature sensor has high measurement accuracy. When used in combination with the infrared temperature sensor 2a, it can better meet the needs of more precise temperature control of medical liquids that are continuously input into the human body for a long time.

[0028] At least two second temperature measuring elements 3 are provided, and at least two second temperature measuring elements 3 are arranged adjacent to each other; this can reduce the temperature difference between the two second temperature measuring elements 3 caused by physical factors. When at least two second temperature measuring elements 3 are provided, the controller performs temperature control based on multiple sets of data, achieving higher accuracy. For example, if the difference in measured values ​​between the second temperature measuring elements 3 exceeds 0.5°C, an alarm can be activated and an inspection can be performed to prevent problems such as sensor failure or partial failure of the heating element, which may result in the liquid temperature not meeting the required value due to untimely adjustment.

[0029] The first temperature measuring element 2 and each second temperature measuring element 3 may be arranged along the flow direction of the liquid.

[0030] The thermostat includes a base 1, which is provided with a temperature measuring groove for embedding a liquid pipeline. A first temperature measuring element 2 and a second temperature measuring element 3 are both disposed within the temperature measuring groove. The liquid pipeline is embedded within the temperature measuring groove, ensuring stable contact with the temperature measuring elements, thereby improving temperature measurement accuracy. Furthermore, a light shielding cover 5 is provided on the base 1. The light shielding cover 5 is movably connected to the base 1 and can cover at least the groove section of the temperature measuring groove where the first temperature measuring element 2 is located. Opening the light shielding cover 5 allows replacement of the liquid pipeline, while closing the light shielding cover 5 prevents the infrared temperature sensor 2a from being interfered with by ambient light and causing inaccurate measurements.

[0031] In some embodiments, a heat conducting plate 4 is provided on the base 1, and the heat conducting plate 4 is embedded in the temperature measuring tank. The second temperature measuring element 3 is fixed on the heat conducting plate 4. For example, a groove is provided on the heat conducting plate 4, and the second temperature measuring element 3 is embedded in the groove and fixed to the heat conducting plate 4 by welding, bonding, or fastening with fasteners such as screws. At the same time, the second temperature measuring element 3 is exposed on the first surface 41 of the heat conducting plate 4. For example, the second temperature measuring element 3 is flush with the first surface 41 of the heat conducting plate 4 or slightly protrudes from the first surface 41, and the second temperature measuring element 3 and the first surface 41 of the heat conducting plate 4 are both used to contact the liquid pipeline. Such a configuration facilitates the fixing of the second temperature measuring element 3. More importantly, the heat transfer through the heat conducting plate 4 can make the measurement of the second temperature measuring element 3 more accurate and faster.

[0032] In a preferred embodiment, the first surface 41 of the thermally conductive sheet 4, where the second temperature-measuring element 3 is exposed, protrudes beyond the wall of the temperature measuring bath. That is, in the depth direction of the bath, the distance between the first surface 41 of the thermally conductive sheet 4 and the opening of the bath is less than the distance between the wall and the opening of the bath. This ensures that the first surface 41 of the thermally conductive sheet 4 and the second temperature-measuring element 3 make smooth, close-fitting contact over a large area with the outer wall of the liquid pipeline embedded in the bath, improving temperature measurement accuracy.

[0033] To ensure the stability of the liquid pipeline within the temperature measuring bath, the cross-section of the temperature measuring bath is semicircular. That is, the central angle corresponding to the curved wall of the temperature measuring bath in the width direction is 180 degrees. Of course, it can also be greater than 180 degrees, such as 210 degrees, 250 degrees, 270 degrees, etc. The heat conducting sheet 4 is a curved sheet, and its curvature can be consistent with the curvature of the temperature measuring bath.

[0034] In some embodiments, the central angle of the arc-shaped sheet in the width direction of the groove is smaller than the central angle of the temperature measuring groove. That is, in the width direction of the temperature measuring groove, the edges of the heat conducting sheet 4 on both sides are spaced apart from the edges of the temperature measuring groove on both sides, such as Figure 1 As shown, this facilitates the stable fixation of the heat conducting sheet 4.

[0035] In some embodiments, the heat conducting sheet 4 is detachably connected to the base 1 , so as to facilitate operations such as disassembly, inspection, and replacement of the second temperature measuring element 3 .

[0036] The structure of the heat conducting sheet 4 and the base 1 can be as follows: the base 1 includes a shell having an inner cavity and a cover plate covering the shell cavity opening, the cover plate is used to connect to the device body, a temperature measuring groove is formed on the outer surface of the shell, and an opening connected to the inner cavity is provided on the groove wall of the temperature measuring groove; the heat conducting sheet 4 includes a main body and positioning parts located at both ends of the main body, and the second temperature measuring element 3 is provided on the main body; in the thickness direction, the main body and the positioning parts are stepped and have a height difference; the heat conducting sheet 4 is located in the inner cavity of the shell and the positioning parts abut against the shell, while the main body is embedded in the opening of the temperature measuring groove and the outer surface protrudes from the groove wall of the temperature measuring groove, that is, the heat conducting sheet 4 embeds the main body into the opening on the shell from the inside of the shell, so that the outer surface of the main body (equivalent to the first surface 41 of the second temperature measuring element 3 exposed as mentioned above) protrudes from the groove wall of the temperature measuring groove. The positioning parts and the shell can be bonded, connected by fasteners, or fixed by pressure from other components. For example, a rubber block is also provided in the inner cavity of the shell, and the rubber block presses the heat conducting sheet 4 against the shell. The rubber block can be connected to the heat conducting sheet 4 and the shell by screws, or the rubber block is connected to the heat conducting sheet 4 by screws. After the cover plate is closed and connected to the shell, it presses the rubber block and the heat conducting sheet 4. In addition, the main body of the heat conducting sheet 4 is clamped by the opening, so that it can be fixed.

[0037] With such a configuration, the base 1 is in a shell structure, and the heat conducting sheet 4 is fixed inside the shell, so that no uneven connection points appear on the wall of the temperature measuring tank. At the same time, through the fit and abutment between the positioning portion and the shell, the heat conducting sheet 4 can be firmly installed in the shell, and its main body with the second temperature measuring element 3 can firmly and smoothly emerge from the opening of the temperature measuring tank, ensuring the flatness of the main body and ensuring that the first surface 41 is in contact with a large area of ​​the liquid pipeline.

[0038] In some embodiments, such as Figure 1As shown, the base 1 is also provided with a pipe-fixing groove for inserting the liquid pipeline. The pipe-fixing groove extends in the same direction as the temperature measuring groove and is narrower than the temperature measuring groove. The pipe-fixing groove can be used to secure other sections of the liquid pipeline, thus making the liquid pipeline more stable. Furthermore, the narrow pipe-fixing groove and wide temperature measuring groove mean that liquid pipelines, such as infusion tubes, can be of a relatively conventional diameter, requiring only a widening at the temperature measuring section to increase the contact area with the thermal conductive plate 4 and improve temperature measurement accuracy.

[0039] The light shield 5 can cover only the temperature measuring slot or both. If the tube fixing slot and the temperature measuring slot are placed side by side, the light shield 5 will cover both slots entirely, or in other words, the front surface of the base 1 where the two slots are located. In this way, the light shield 5 can be connected to both sides of the base 1. For example, one side of the base 1 can be rotatably connected to the light shield 5, while the other side can be equipped with a snap-fit ​​structure to secure the light shield 5 and prevent it from tilting.

[0040] Specifically, the movable connection between the light-shielding cover 5 and the base 1 can be a sliding connection or a rotating connection. For example, one side of the light-shielding cover 5 is rotationally connected to the base 1 through a rotating shaft, and the other side is snap-connected to the base 1 through a snap-fit ​​structure (such as a snap-fitting groove is provided on the base 1 and a snap-fitting body is provided on the light-shielding cover 5 that is embedded in the snap-fitting groove); or, there are sliding grooves on both side walls of the base 1, and the light-shielding cover 5 is U-shaped, including a light-shielding plate and side panels located on both sides of the light-shielding plate, and the side panels are provided with convex strips for embedding in the sliding grooves, so that the light-shielding cover 5 is connected to the base 1 through a sliding structure.

[0041] In some embodiments, the light shielding cover 5 may further be provided with a dark light shielding member 51. When the light shielding cover 5 is in the closed state, the dark light shielding member 51 at least covers the first temperature measuring element 2, ie, the infrared temperature sensor 2a.

[0042] The present application also provides a heating module comprising a heating chamber, a heating element, and a thermostat as described in any of the above embodiments. The first temperature measuring element 2 and the second temperature measuring element 3 in the thermostat are both connected to a controller circuit, and the heating element is also connected to the controller circuit, so that the controller controls the heating element based on temperature measurement data from the temperature measuring elements. For example, the controller adjusts the power of the heating element based on feedback data from the first temperature measuring element 2 and controls the heating element's shutdown based on feedback data from the second temperature measuring element 3, thereby precisely controlling the liquid temperature.

[0043] The heating chamber can be a monolithic cubical cavity. Alternatively, in some embodiments, the heating module includes a heating plate. Rather than a monolithic disc-shaped heating chamber, the heating plate comprises multiple interconnected annular channels that wind from the inside out, each forming a heating chamber. This allows for more uniform heating and a more uniform temperature of the liquid within each channel, facilitating more precise control of the heating temperature of the entire liquid.

[0044] An embodiment of the present application also provides a blood treatment device, including a device body, on which the above-mentioned temperature controller or the above-mentioned heating module is provided. The device body may also be provided with an alarm connected to the temperature controller for communicating with the temperature controller, so as to generate an alarm in time when the measured temperature difference of different sensors exceeds a set value such as 0.5°C.

[0045] Specifically, the blood treatment device is a hemodialysis device or a continuous blood purification device. Thus, when a patient is continuously infused with a liquid medicine for a long period of time, the blood treatment device provided by the present application can more accurately control the liquid medicine temperature, thereby reducing the patient's discomfort with the treatment.
