Description

Technical Field

[0001] The utility model relates to the technical field of temperature-raising instruments, in particular to a blood transfusion and infusion temperature-raising instrument. Background Art

[0002] The working principle of the portable blood transfusion and infusion warming device is mainly to raise the temperature of the infusion or blood transfusion to close to the normal body temperature through a heating device, so as to reduce the adverse reactions caused by the infusion of low-temperature liquids.

[0003] The equipment currently available on the market does not have the function of detecting the temperature of the pipeline or liquid. The actual heating effect is controlled by the sensor on the heating plate of the equipment. When the flow rate is too large, the liquid cannot be heated to the actual set temperature. In response to the above defects, this application is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a blood transfusion and infusion temperature increasing instrument, which provides a reference for adjusting the heating temperature by accurately monitoring the temperature of the pipeline, and solves the problem that the liquid temperature is difficult to reach the set requirements when the flow rate is too large.

[0005] To solve the above problems, the present invention provides a blood transfusion and infusion warming device, comprising a warming device body, a heating plate, a temperature monitoring component and a pipeline heat conduction component. A warming chamber is provided in the warming device body. The temperature monitoring component comprises a heating plate temperature sensor and a pipeline temperature sensor. The pipeline heat conduction component is used to contact the liquid delivery pipeline. The pipeline temperature sensor is connected to the pipeline heat conduction component to measure the pipeline temperature, thereby realizing indirect measurement of the temperature of the heated liquid. The pipeline temperature sensor is electrically connected to the heating plate. When the liquid flow rate increases and the pipeline temperature sensor detects that the liquid temperature has not reached the set value, the heating plate adjusts the heating temperature.

[0006] According to an embodiment of the present invention, the contact position between the pipeline heat conduction component and the pipeline is arc-shaped, thereby obtaining a larger contact area, and is generally in the shape of a semicircle.

[0007] According to an embodiment of the present invention, the pipeline heat conduction component includes a metal sheet and a fixing seat. The metal sheet is used to contact the pipeline. The fixing seat can also be made of metal material. The fixing seat is used to be installed on the temperature rising device body.

[0008] According to an embodiment of the present invention, the heating chamber is a square chamber, but is not limited to a square chamber and may also be a cylindrical chamber.

[0009] According to an embodiment of the present invention, at least two groups of heating plates are provided, which are respectively arranged on both sides of the heating chamber to ensure the heating effect.

[0010] According to an embodiment of the present invention, the temperature monitoring component further includes a second heating plate temperature sensor.

[0011] According to one embodiment of the present invention, the main body of the temperature rising instrument includes two combination parts, and the heating chamber is formed between the two combination parts. The opening and closing of the two combination parts respectively realize the opening and closing of the heating chamber. The heating chamber is closed, which is beneficial to the rapid heating and heat preservation effect of the liquid, but is not limited to a closed heating chamber. An open type may also be used in other embodiments.

[0012] According to an embodiment of the present invention, the two combination parts are hingedly connected, but are not limited to hinged connections, and may also be split-type buckle connections.

[0013] According to an embodiment of the present invention, the combined portion includes a housing and a heating plate base, and the heating plate is arranged between the housing and the heating plate base.

[0014] According to an embodiment of the present invention, a mounting groove for installing a temperature monitoring component is provided on the heating plate base, which facilitates the positioning and installation of the temperature sensor.

[0015] The beneficial effect of the present invention is that, by setting a temperature monitoring component and a pipeline heat conduction component, the pipeline temperature sensor in the temperature monitoring component cooperates with the pipeline heat conduction component to measure the temperature of the pipeline, thereby indirectly obtaining the temperature parameters of the liquid after heating. When the liquid flow rate increases, the information of the liquid temperature drop can be obtained in a timely and accurate manner, and then a temperature adjustment instruction to increase the temperature is sent to the heating plate to ensure that the liquid temperature remains within the set range, thereby solving the problem that the traditional temperature increasing instrument does not have the ability to directly measure the pipeline temperature, resulting in the liquid temperature rising not meeting the set requirements. In addition, the present solution provides a temperature detection matching part on the blood transfusion and infusion temperature increasing instrument kit, on which a groove for matching temperature detection is provided, which can ensure the effective conduction of the pipeline temperature, thereby ensuring the accuracy of the temperature measurement, which is beneficial to the control of the liquid temperature.

[0025] The following description is intended only to disclose the present invention and to enable those skilled in the art to implement the present invention. The embodiments described below are provided for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0026] [Example 1]

[0027] The blood transfusion and infusion temperature increasing device 1 comprises a temperature increasing device body 11 , a heating plate 13 , a temperature monitoring component 15 and a pipeline heat conducting component 17 .

[0028] like Figure 1 、 Figure 6 The temperature rising instrument body 11 includes two combination parts, and a closed heating chamber 16 is formed between the two combination parts during heating. The opening and closing of the heating chamber 16 are respectively realized by the opening and closing of the two combination parts.

[0029] During heating, the closed heating chamber 16 is beneficial to the rapid heating and heat preservation of the liquid, but is not limited to a closed heating chamber, and an open chamber may also be used in other embodiments.

[0030] The two combined parts can be hinged or split-type snap-fitted. In this embodiment, they are hinged.

[0031] The shape of the heating chamber 16 is the same as that of the heating kit used in conjunction therewith, and can be set to a circular, square or other shape. In this embodiment, it is set to a square sheet, and heating plates 13 are respectively set on both sides to achieve a better heating effect.

[0032] Each combination part should adopt the same structure to reduce costs. Figure 5The assembly includes an outer shell 12 and a heating plate base 14. The heating plate 13 is arranged between the outer shell 12 and the heating plate base 14. A heating plate protective plate 19 is also provided between the outer shell 12 and the heating plate 13. A heat conduction component fixing groove 141 is provided at the end of the heating plate base 14, and an installation groove for installing the temperature monitoring component 15 is provided on the heating plate base 14.

[0033] The temperature monitoring component 15 includes a heating plate temperature sensor 151 and a pipe temperature sensor 153. Preferably, the temperature monitoring component 15 also includes a heating plate temperature sensor 2 152. The heating plate temperature sensor 151 and the heating plate temperature sensor 2 152 are arranged away from the heating plate 13 in sequence to obtain more and more reliable temperature parameters.

[0034] like Figure 7 The pipeline heat conduction component 17 includes a metal sheet 172 and a fixing seat 171. The metal sheet 172 is used to contact the pipeline. In order to obtain a larger contact area, the metal sheet 172 is set to an arc shape. The fixing seat 171 is used to fix the metal sheet 172. The fixing seat 171 is installed in the fixing groove 141 of the heat conduction component.

[0035] The pipeline temperature sensor 153 is in contact with the fixing seat 171 and may also be in direct contact with the metal sheet 172 .

[0036] The pipeline temperature sensor 153 is connected to the pipeline heat conduction component 17 to measure the temperature of the heated liquid. The pipeline temperature sensor 153 is electrically connected to the heating plate 13. When the liquid flow increases and the pipeline temperature sensor 153 detects that the liquid temperature has not reached the set value, the heating plate 13 adjusts the heating temperature.

[0037] The heating plate 13 and the temperature monitoring component 15 are both connected to the control module, which is external or built into the temperature rising instrument body 11. The control module can be implemented using a microprocessor, a computer, a PLC programmable controller, etc. When the pipeline temperature sensor 153 detects that the liquid temperature has not reached the set value, the control module adjusts the heating temperature of the heating plate 13.

[0038] The blood transfusion and infusion warming device 1 can be powered by a built-in battery or an external power supply.

[0039] The blood transfusion and infusion warming device 1 is used together with the blood transfusion and infusion warming device kit 2, such as Figure 2 、 Figure 3 The blood transfusion and infusion warming instrument kit 2 is a consumable and disposable material, and includes a warming body 21, a pipeline 22 connected to the warming body 21, and a temperature detection matching part 27 provided on the pipeline 22.

[0040] The pipeline 22 includes a liquid inlet pipeline and a liquid outlet pipeline, which are respectively arranged at both ends of the heating body 21, and the temperature detection matching part 27 is installed on the liquid outlet pipeline.

[0041] An inner conical joint 25 and an outer conical joint 23 are respectively installed on the liquid inlet pipeline and the liquid outlet pipeline. An inner conical joint protective cap 26 is installed at the inner conical joint 25, and an outer conical joint protective cap 24 is installed at the outer conical joint 23. The inner conical joint 25 and the outer conical joint 23 are used to connect with the infusion pipeline.

[0042] The outer conical joint protection cap 24 and the inner conical joint protection cap 26 are used to protect the interface.

[0043] The temperature detection cooperation part 27 is as follows Figure 7 As shown, it is tubular and wrapped around the pipeline, and a temperature detection groove 271 is provided on the outer wall. The temperature detection groove 271 is preferably extended on the outer circumference of the temperature detection matching portion 27 to form an arc groove. When heating, the heating body 21 is placed in the heating chamber 16. The two sides of the square sheet-shaped heating body 21 with larger areas are heated surfaces, so that the liquid inside it is easier to be heated, as shown in FIG. Figure 8 At this time, the metal sheet 172 is embedded in the temperature detection groove 271, thereby achieving a larger heat conduction area and being able to accurately measure the pipeline temperature.

[0044] The material of the temperature detection matching portion 27 can be selected from metal, ceramic, polymer material, etc.

The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments.
