For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood in combination with specific circumstances.

[0025] The following will refer to the attached Figures 1 to 3 The utility model is described in detail in conjunction with the embodiments.

[0026] In general, the utility model relates to a heating and pressurizing infusion device with infusion monitoring, including a shell 1, a main board 5 arranged on the shell 1, a pressurizing component arranged on the shell 1 and electrically connected to the main board 5, a heating tube 4 electrically connected to the main board 5, a detection component electrically connected to the main board 5, and a heating component electrically connected to the main board 5.

[0027] like Figure 1 As shown, the heating component includes a heating tube 4 and an inner groove 401 . The heating tube 4 is electrically connected to the main board 5 . The heating tube 4 is provided with an inner groove 401 that follows the length of the heating tube.

[0028] In this embodiment, the shell 1 is used to start and fix the main board 5 and the pressurizing component, which is convenient for the main board 5 to control the pressurizing component, the detection component and the heating component. The pressurizing component can detect and adjust the pressure of the infusion bag to ensure that the medicine can be smoothly infused into the patient's body during infusion. The detection component can detect the infusion tube to prevent the bubbles in the infusion tube from being infused into the human body, causing air embolism in the patient and blood reflux at the patient's infusion site. The heating component can heat the infusion tube to prevent the medicine temperature from being too low and causing discomfort to the infusion recipient.

[0029] During the specific implementation, the infusion bag is placed into the pressurizing component, the infusion line extends from the bottom of the pressurizing component to the detection component for bubble detection, and the infusion line extending from the detection component is placed from the inner groove 401 into the heating tube 4.

[0030] It should be understood that the structure of the heating tube 4 consists of a heating part and a supporting and wrapping part. The supporting and wrapping part is made of soft silica gel, which is both a load-bearing structure and a heat transfer body, and also an insulating layer to prevent current leakage. The heating part is wrapped inside the supporting and wrapping part to perform an electric heating function.

[0031] In order to facilitate the quick connection between the heating tube 4 and the housing 1, preferably, the heating tube 4 and the housing 1 are plug-in connected via a connector 402. The connector 402 is a quick plug connector 402.

[0032] like Figure 1 and Figure 2 As shown, the above-mentioned pressurizing component includes a pressurizing pump 101 arranged on the shell 1 and electrically connected to the main board 5, a pressure detector 102 arranged on the shell 1 and electrically connected to the main board 5, and a pressurizing cover 201 connected to the pressurizing pump 101 and the pressure detector 102 through a connecting pipe 2, and the interior of the pressurizing cover 201 is hollow.

[0033] In addition, in order to fix the pressurizing cover 201 inside the pressurizing cover 201, based on the setting of the pressurizing component, a fixing component for fixing the infusion bag is also provided in the pressurizing cover 201, and the fixing component includes a fixing plate 202 fixedly arranged on the inner wall of the pressurizing cover 201, a lock buckle 205 fixedly arranged on the fixing plate 202, a connecting piece 203 arranged on the lower side of the fixing plate 202, and a lock port 204 spaced apart on the connecting piece 203 and matching the lock buckle 205.

[0034] During the specific implementation, the infusion bag is placed in the pressurized cover 201, the connecting piece 203 is passed through the hole of the infusion bag, and then the lock 204 is hung on the lock buckle 205. When pressurization is required, the pressure pump 101 is started to pressurize the pressurized cover 201 through the connecting tube 2, and the infusion bag is squeezed to increase the pressure in the infusion tube, so that the liquid medicine can enter the human body smoothly. The pressure detector 102 can detect the pressure in the pressurized cover 201 to prevent excessive pressure from causing damage to the patient. It should be noted that the multiple locks 204 arranged at intervals can adapt to infusion bags of different sizes.

[0035] like Figure 1As shown, the above-mentioned detection component includes a mounting member 3 electrically connected to the mainboard 5, a slot 301 provided on the mounting member 3, and an infrared detector 302 disposed in the slot 301. The working principle of the infrared detector 302 is to emit infrared light into the infusion tube and receive the infrared light reflected or transmitted back. When there are bubbles in the infusion tube, the reflection or transmission characteristics of the bubbles to infrared light are different from those of the liquid, so the infrared detector 302 can capture this difference and generate a signal. By processing and analyzing the signal, the existence, size and position of the bubble can be accurately determined.

[0036] During specific implementation, the infusion tube prevents the infusion line from entering the groove 301, and a stop device is set according to actual conditions. Once bubbles are detected, it can automatically stop or slow down to prevent the bubbles in the infusion tube from being infused into the human body and causing air embolism in the patient.

[0037] It needs to be further explained that if Figure 1 and Figure 3 As shown, the housing 1 is provided with a control panel 103 which is formed in accordance with the outline of the housing 1, and the control panel 103 is electrically connected to the main board 5. The control panel 103 can control the operation of the main board 5 and thus the booster pump 101, observe the data of the pressure detector 102, receive the alarm signal of the infrared detector 302, and the current of the heating tube 4 can be turned on and off.

[0038] It should be further explained that the mainboard 5 is an STM32 single-chip microcomputer chip.

[0039] In summary, the utility model, by inflating the pressurized bag and then squeezing the infusion bag or blood transfusion bag, produces the function of rapid infusion or blood transfusion. The combined use of the pressurizing component, the detection component and the heating component can achieve the purpose of rapid infusion or blood transfusion by heating and pressurizing, and also implement measures to prevent and control bubbles during the infusion or blood transfusion process. When the infusion monitoring device detects bubbles in the infusion or blood transfusion tube, it immediately sounds an audible and visual alarm, and intercepts the infusion or blood transfusion tube. The host control part immediately stops heating and pressurizing. After the manual operation cancels the audible and visual alarm, the host control part is operated and the device continues to work normally.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
