The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0027] In the embodiment of the utility model, the liquid level sensing device of the contrast syringe can be used to detect the content of the liquid medicine in the medicine bottle.

[0028] Combine the following Figures 1 to 5 , the angiographic syringe liquid level sensing device provided in the embodiment of the present application is described in detail through specific examples.

[0029] The liquid level sensing device 100 for an angiographic syringe provided in one embodiment of the present invention comprises a support frame 10 and a liquid level sensor 20. The support frame 10 is used to place a medicine bottle; the liquid level sensor 20 is arranged on the support frame 10, and the liquid level sensor 20 is attached to the medicine bottle; wherein the liquid level sensor 20 is attached to the bottle mouth of the medicine bottle to detect the amount of liquid medicine in the medicine bottle.

[0030] The support frame 10 is used to place the medicine bottle. When injecting the medicine liquid, the bottle mouth of the medicine liquid faces downward, so that the medicine liquid in the medicine bottle flows downward by gravity to achieve the injection of the medicine liquid.

[0031] In this embodiment, the liquid level sensor 20 is arranged on the support frame 10, and the liquid level sensor 20 is fitted with the medicine bottle. Among them, the liquid level sensor 20 is fitted with the bottle mouth of the medicine bottle to detect the amount of liquid medicine in the medicine bottle. The liquid level sensor 20 is usually installed on the support frame 10 and fits with the medicine bottle to ensure the accuracy and stability of the contact between the liquid level sensor 20 and the liquid medicine. Through the fit of the liquid level sensor 20 with the bottle mouth of the medicine bottle, the liquid level sensor 20 can accurately detect the liquid level change of the liquid medicine. And the amount of liquid medicine is determined by measuring capacitance, pressure change, flow rate and other methods. Thereby preventing the injection from failing when there is too little liquid medicine in the medicine bottle, or even injection bubbles entering the human body. Reduce safety hazards.

[0032] In some embodiments, the support frame 10 includes a fixed bracket 11, and the fixed bracket 11 is arranged close to the medicine bottle. The liquid level sensor 20 is installed on the fixed bracket 11 so that the liquid level sensor 20 fits the bottle mouth of the medicine bottle. The liquid level sensor 20 maintains a firm connection with the medicine bottle, and enables the liquid level sensor 20 to accurately contact the medicine liquid so as to measure the liquid level information of the medicine liquid, thereby facilitating accurate drug management and control in medical or experimental fields. Specifically, the fixed bracket 11 is usually adapted to the shape of the medicine bottle to ensure that the liquid level sensor 20 can completely fit the bottle mouth of the medicine bottle. Through such a setting, the liquid level sensor 20 can be prevented from loosening or falling off during operation.

[0033] In some embodiments, a first mounting hole 111 is provided on the fixing bracket 11, and the liquid level sensor 20 is installed in the first mounting hole 111, and the edge of the liquid level sensor 20 abuts against the edge of the first mounting hole 111. Through such a configuration, it can be ensured that the liquid level sensor 20 is firmly mounted on the fixing bracket 11, and the connection between the liquid level sensor 20 and the fixing bracket 11 is tight. By abutting the edge of the liquid level sensor 20 against the edge of the first mounting hole 111, additional stability and support can be provided to prevent the sensor from loosening or shifting during use.

[0034] The diameter of the first mounting hole 111 is the same as that of the liquid level sensor 20 to ensure that the liquid level sensor 20 can be tightly installed and aligned with the surface or edge of the fixing bracket 11. Through such a setting, the liquid level sensor 20 can maintain a fit with the mouth of the medicine bottle and accurately measure the liquid level information of the medicine.

[0035] In some embodiments, the fixed bracket 11 includes a connection end 112, and the connection end 112 is connected to the support frame 10. The connection end 112 can be used to connect the fixed bracket 11 and the support frame 10. The connection end 112 can be connected to the support frame 10 by a threaded connection, an insert connection, or a snap connection. Through the connection between the connection end 112 and the support frame 10, the fixed bracket 11 can be firmly fixed on the support frame 10, ensuring the stability and reliability of the liquid level sensor 20 and its installation on the fixed bracket 11. Through such a setting, a tight connection between the support frame 10 and the fixed bracket 11 can be provided, and the liquid level sensor 20 can be prevented from loosening or shifting during use.

[0036] In some embodiments, the liquid level sensor 20 is a capacitive liquid level sensor 20. The capacitive liquid level sensor 20 is a common liquid level measuring device that uses changes in capacitance to measure the liquid level height of the liquid. It is usually composed of two electrodes, one of which is fixed and the other moves as the liquid level changes. When the liquid contacts the electrode, a capacitor is formed between the liquid and the electrode, and its size is proportional to the liquid level height. The capacitive liquid level sensor 20 determines the height of the liquid level by measuring the change in capacitance. The circuit inside the sensor measures the capacitance and converts it into a corresponding electrical signal output for monitoring and control of the liquid level. This sensor has the advantages of high precision, good stability, and fast response speed.

[0037] In some embodiments, the support frame 10 is further provided with a second mounting hole 12, and the medicine bottle is placed on the support frame 10 through the second mounting hole 12. The second mounting hole 12 can mount the medicine bottle on the support frame 10, so that the medicine bottle remains stable and fixed during use. Through the second mounting hole 12, the medicine bottle can be accurately placed on the support frame 10, so that the medicine bottle is not easy to tilt, shake or slide during use. This helps to maintain a stable contact between the medicine bottle and the liquid level sensor 20, ensuring accurate measurement of the liquid level and safe injection of the liquid medicine.

[0038] In some embodiments, the support frame 10 also includes a clamping portion 13, which is located on both sides of the support frame 10, and the clamping portions 13 on both sides fit with the medicine bottle, and the clamping portion 13 is used to fix the medicine bottle on the support frame 10. By fitting the clamping portion 13 with the medicine bottle, additional holding force and stability can be provided to achieve a good clamping effect. Ensure that the medicine bottle does not slide or tilt during use. Through such a setting, it can be ensured that the medicine bottle is firmly mounted on the support frame 10, so that the liquid level sensor 20 maintains close contact with the medicine bottle, thereby accurately measuring the liquid level information of the medicine liquid.

[0039] In some embodiments, the clamping portion 13 is provided with a clamping groove 131, and the clamping groove 131 is used to place the mouth of the medicine bottle. The clamping groove 131 of the clamping portion 13 can be specifically a groove, which is used to accommodate the mouth of the medicine bottle. Among them, the size of the clamping groove 131 is adapted to the size of the mouth of the medicine bottle to ensure that the medicine bottle can be safely and firmly placed on the clamping portion 13. Through such a setting, the clamping portion 13 can firmly grasp the medicine bottle to prevent it from sliding or tilting.
