Description

Technical Field

[0001] The utility model relates to the technical field of drug injection, in particular to a boosting device for assisting ultrasonic-guided injection. Background Technique

[0002] Injecting local anesthetic around the nerve trunk, plexus, and ganglion to block its impulse conduction and cause anesthetic effect in the innervated area is called nerve block. Generally, under B-ultrasound, through the use of a B-ultrasound nerve block puncture needle disclosed in the utility model patent with the application number 202020099316.1 and a nerve block puncture needle disclosed in the utility model patent with the application number 202122940982.0, etc., the drug is injected into the designated area.

[0003] However, due to the relatively simple structure of the existing puncture needles, during use, first, it is necessary to use B-ultrasound to detect the position to be punctured, and at the same time insert the puncture needle into the designated position. Then, connect the puncture needle to the syringe, and then inject the drug into the patient's body. The above operations need to be completed by multiple people cooperating. Moreover, when connecting the syringe and injecting the drug, the puncture needle is prone to displacement, and there are many nerves around it, which is likely to cause harm to the patient, resulting in poor practicability. Therefore, there is an urgent need for a boosting device for assisting ultrasonic-guided injection to improve the above problems. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a boosting device for assisting ultrasonic-guided injection. The drug is inhaled into its interior through an injection mechanism, then the puncture needle is inserted into the designated position in the patient's body, and then the injection mechanism is installed on the driving mechanism and connected to the puncture needle. Then, the driving mechanism pushes the injection mechanism to discharge the drug into the puncture needle, and then the drug is discharged into the patient's body through the puncture needle, which is convenient for a single staff member to complete the drug injection and reduces the shaking and displacement of the puncture needle, thereby improving the practicability of the device.

Next, the injection mechanism is installed on the driving mechanism, and the injection mechanism is connected to the puncture needle. After that, the driving mechanism is used to push the injection mechanism, so that the injection mechanism discharges the drug into the puncture needle, and then the drug is discharged into the patient's body through the puncture needle, which is convenient for a staff member to complete the injection of the drug and reduces the shaking and displacement of the puncture needle, thereby improving the practicability of the device.

[0008] Preferably, the injection mechanism includes an injection cylinder, a piston, a push rod, and a delivery hose. The piston is slidably installed inside the injection cylinder. The push rod is installed on the piston. One end of the delivery hose is installed at the left end of the injection cylinder. By pulling the push rod, the piston slides inside the injection cylinder to inhale the drug into the injection cylinder. When injecting the drug later, the other end of the delivery hose is installed on the puncture needle. By pushing the push rod to the left, the piston squeezes the drug in the injection cylinder, discharges the drug into the puncture needle, and then the drug is discharged into the patient's body through the puncture needle, thereby improving the practicability of the device.

[0009] Preferably, the driving mechanism includes a base, a bracket, an electric push rod, a connecting wire, a control switch, and multiple groups of limit frames. The electric push rod is installed at the top of the base through the bracket. Multiple groups of limit frames are all installed at the top of the base. The control switch is connected to the electric push rod through the connecting wire. The injection cylinder is clamped on the top of the base by multiple groups of limit frames, and the left end of the electric push rod is attached to the right end of the push rod. When injecting the drug, by stepping on the control switch, the electric push rod extends to squeeze the push rod, discharges the drug in the injection cylinder into the puncture needle, and then the drug is discharged into the patient's body through the puncture needle, thereby improving the practicability of the device.

[0010] Preferably, the limit frame includes two groups of fixed frames, two groups of springs, and two groups of clamping plates. The two groups of fixed frames are both installed on the base.

The injection cylinder is placed between the two groups of clamping plates, and through the elasticity of the two groups of springs, the two groups of clamping plates clamp the injection cylinder to fix the injection cylinder, thereby improving the practicability of the device.

[0011] Preferably, a flow-limiting valve is provided on the delivery hose. The flow rate of the drug is restricted by the flow-limiting valve to prevent a large amount of drug from quickly entering the patient's body, thereby improving the practicability of the device.

[0012] Preferably, the top of the base is an inclined surface from right to left, which facilitates the left end of the injection cylinder to tilt downward and improves the convenience of drug injection.

[0013] Preferably, multiple groups of suction cups are provided at the bottom end of the base. The base is placed on the table, and by pressing the base downward, the multiple groups of suction cups are adsorbed on the table to limit the base, thereby improving the stability of the base.
