Description

Technical Field

[0001] The utility model relates to the technical field of syringes, in particular to a heart rate monitoring syringe. Background Art

[0002] Syringes are commonly used instruments in medical practices. At present, injections in human or animal tissues or joints are quite common. Syringes are generally composed of syringe needles, syringes, pistons and push rods. Liquid injection is performed under the action of the push rod. Syringes are one of the efficient and effective ways to deliver drugs to patients. However, according to relevant medical reports, syringes have a relatively large impact on heart rate and blood pressure when injecting drugs into patients.

[0003] During the use of existing syringes, it is not easy for doctors to intuitively observe the impact of the injection speed on the patient's heart rate and blood pressure. Usually, the patient will only tell the doctor to stop injecting the drug when he feels unwell, which may easily cause the patient to feel unwell. In addition, when injecting drugs to patients, the injection speed of the drug is related to the patient's physical signs and needs to be set according to the upper and lower thresholds of the patient's blood pressure and / or heart rate. Otherwise, it is easy to cause a deviation between the ideal infusion speed and the actual infusion speed. For this reason, we propose a heart rate monitoring syringe to solve the above problems.

[0009] Furthermore, the injection assembly includes a sealing ring, a piston rod, a pulling rod and an infusion tube. The sealing ring is arranged inside the medicine liquid tank and is slidably connected to the medicine liquid tank. The inside of the sealing ring is installed with the piston rod. The top surface of the piston rod is fixed to the bottom surface of the pulling rod. The upper surface of the infusion tube is connected to the lower surface of the medicine liquid tank.

[0010] Furthermore, two fixing rings are fixed on the outer surfaces of the two medicine liquid tanks, and the fixing rings are installed on the right end of the frame.

[0022] The running mechanism includes four moving wheels 6 installed on the lower surface of the frame 1 for moving the frame 1, and the four moving wheels 6 are all universal wheels.

[0023] In this embodiment, by setting up the electrocardiogram monitor body 2 and the blood pressure monitor body 3, the patient's body can be monitored in real time, and the infusion can be more intuitively observed to monitor the patient's heartbeat and blood pressure in real time. At the same time, by setting up the delivery component and the injection component, the infusion volume can be controlled in real time through the control part in the controller 17 according to the patient's blood and / or heartbeat being too high or too low.

[0024] It should be noted that, by setting a command input part in the controller 17, the doctor can input the push injection speed, or set the upper and lower heart rate thresholds according to the patient's condition, and set them according to different patient signs; and by setting the control part, the speed of the servo motor 7 is controlled according to the set speed and / or threshold input by the doctor, and then the advancement speed of the infusion tube 15 is controlled by the servo motor 7.

[0025] See also Figure 2 and Figure 3In order to push the liquid medicine in the liquid medicine tank 5 to the infusion tube 15, the conveying assembly in this embodiment includes a servo motor 7 fixed to the bottom surface of the installation box 4, and the output shaft of the servo motor 7 passes through and extends to one end of the installation box 4 and is installed with a screw rod 8. The outer surface of the screw rod 8 is threadedly connected with a movable plate 9, and a slider 10 is fixed to the left end of the movable plate 9. The front and rear ends of the movable plate 9 are fixed with connecting rods 11 that pass through and extend to the front and rear ends of the installation box 4 respectively.

[0026] A slide groove is provided at the right end of the inner cavity of the installation box 4 , the left end of the slider 10 is located inside the slide groove and is slidably connected thereto, and the controller 17 is electrically connected to the ECG monitor body 2 , the blood pressure monitor body 3 and the servo motor 7 .

[0027] The injection assembly includes a sealing ring 12, a piston rod 13, a pulling rod 14 and an infusion tube 15. The sealing ring 12 is arranged inside the medicine liquid tank 5 and is slidably connected to the medicine liquid tank 5. The inside of the sealing ring 12 is installed with the piston rod 13, the top surface of the piston rod 13 is fixed to the bottom surface of the pulling rod 14, and the upper surface of the infusion tube 15 is connected to the lower surface of the medicine liquid tank 5.

[0028] Two fixing rings 16 are fixed to the outer surfaces of the two medicine liquid tanks 5 . The fixing rings 16 are installed at the right end of the frame 1 . The lower surfaces of the two connecting rods 11 are fixed to the upper surfaces of the two pulling rods 14 .

[0029] In this embodiment, when the ECG monitor body 2 and / or the blood pressure monitor body 3 detects that the patient's infusion volume is too large, resulting in abnormal body functions, an electrical signal can be transmitted to the controller 17, and the controller 17 controls the rotation speed of the servo motor 7, thereby achieving the purpose of controlling the infusion speed of the infusion tube 15.

[0030] By setting up the electrocardiogram monitor body 2 and / or the blood pressure monitor body 3, the patient's heartbeat and / or blood pressure can be monitored in real time. When the patient's heartbeat and / or blood pressure are detected to be abnormal, the rotation speed of the servo motor 7 will be adjusted to control the flow rate of the infusion tube 15. The degree of influence of the injection speed on the patient's heartbeat and blood pressure can be observed more intuitively. At the same time, the flow rate of the infusion tube 15 can be adjusted in time according to the patient's function during infusion.

[0031] The working principle of the above embodiment is:

[0032] When the patient is infused, the patient's heartbeat and / or blood pressure can be monitored in real time through the ECG monitor body 2 and the blood pressure monitor body 3. When the patient's heartbeat and / or blood pressure is too high or too low, the signal will be transmitted to the controller 17, and then the controller 17 will transmit the instruction to the servo motor 7, so that the speed of the servo motor 7 is adjusted. When the output shaft of the servo motor 7 rotates, it will drive the screw rod 8 to rotate. When the screw rod 8 rotates, it will drive the movable plate 9 on the outer surface of the screw rod 8 to move. Under the limiting action of the slide groove and the slider 10, the movable plate 9 will limit the rotation of the movable plate 9. Further, when the screw rod 8 rotates, it will drive the movable plate 9 to move upward or downward along the screw rod 8, and further drive the two connecting rods 11 to move upward or downward;

[0033] When the two connecting rods 11 move, the pulling rod 14 will be driven to pull the piston rod 13. When the piston rod 13 moves, it will drive the sealing ring 12 to move, thereby driving the liquid medicine in the liquid medicine tank 5 to flow out through the infusion tube 15. By controlling the speed of the servo motor 7 and controlling the infusion volume through the speed of the servo motor 7, the infusion volume can be effectively and accurately controlled, avoiding the traditional method of controlling the infusion volume accurately enough, and the flow of the infusion tube 15 can be effectively controlled.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
