[0002] A syringe consists of a barrel with a small hole at the front end and a piston core rod that matches it, and is used to inject a small amount of liquid or extract it from other inaccessible areas. It is usually applied in the medical field to inject drugs for patients for treatment.
[0003] When a doctor finishes an injection using a syringe, it is necessary to disassemble and replace the needle for the next drug injection. When replacing, usually, the doctor directly pulls out the needle from the barrel by hand, and then installs a new needle on the barrel. However, when directly pulling out the needle by hand, if the force is too large, it is easy to prick the palm, and the safety is relatively low.
[0004] In summary, there is an urgent need for a push - type high - pressure syringe that is convenient to disassemble the needle to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The present utility model will be further described below in conjunction with the drawings and specific embodiments.
[0022] Embodiment: A push-type high-pressure syringe convenient for disassembly, refer to Figures 1-4As shown in the figure, it includes a syringe barrel 1, a guide sleeve 2, a piston 3, a pushing block 4, a fixing sleeve 5, a conical sleeve 6, a limiting rod 7, a first elastic member 8, a pushing sleeve 9, a base 10, a pushing rod 11, a clamping block 12 and a second elastic member 13. The guide sleeve 2 is welded to the inner wall of the syringe barrel 1. Both the syringe barrel 1 and the guide sleeve 2 are transparent. The piston 3 is slidably arranged on the guide sleeve 2. The left part of the piston 3 has the same shape as the left part of the syringe barrel 1. When the piston 3 moves to the left, the drug can be injected into the patient's body. The right side of the piston 3 is connected to the pushing block 4. The pushing block 4 is arranged in a long strip shape with wide sides at both ends and a narrow middle. The fixing sleeve 5 is welded to the outer wall of the syringe barrel 1. Four limiting rods 7 are evenly spaced and slidably arranged on the left part of the outer wall of the syringe barrel 1. A conical sleeve 6 is connected between the left sides of the four limiting rods 7. The conical sleeve 6 is slidably connected to the syringe barrel 1 and fits with it. When the conical sleeve 6 moves to the left, the needle can be pushed out for disassembly. A pushing sleeve 9 is connected between the right sides of the four limiting rods 7. The pushing sleeve 9 is slidably connected to the syringe barrel 1. The pushing sleeve 9 is arranged with a thick left part and a thin right part. A first elastic member 8 is connected between the left side of the pushing sleeve 9 and the syringe barrel 1. The first elastic member 8 is sleeved on the limiting rod 7. The base 10 is welded to the right part of the syringe barrel 1. The pushing rods 11 are slidably arranged on both the upper and lower sides of the base 10. Clamping blocks 12 are welded on the sides of the pushing rods 11 close to each other. When the clamping blocks 12 move outward, the device can be fixed on the specified equipment, which is convenient for installation and fixation. Second elastic members 13 are symmetrically connected between the sides of the clamping blocks 12 away from each other and the base 10 in the front and back directions.
[0023] When the device needs to be used, the doctor first picks up the device, then squeezes the pushing rod 11 inward, driving the clamping block 12 to move inward, stretching the second elastic member 13. Then, according to the need, the device is placed on the specified equipment, making the clamping block 12 align with the position to be clamped. Then, the pushing rod 11 is released, and the second elastic member 13 returns to its original state, driving the pushing rod 11 and the clamping block 12 to move outward and reset. Thus, the device can be fixed on the specified equipment through the clamping block 12. When the patient needs to be injected with drugs, first, the needle is installed on the left side of the syringe barrel 1, and the medicine bottle is aligned with the needle. Then, the pushing block 4 is pulled to move to the right, driving the piston 3 to move to the right, and the liquid in the medicine bottle can enter the guide sleeve 2. At this time, the doctor aligns the needle with the part of the patient to be injected and pierces it. Then, the pushing block 4 is pushed to the left, driving the piston 3 to move to the left, and the liquid can be injected into the patient's body through the needle to complete the injection. After the injection is completed, the needle is pulled out from the patient's skin. Then, the pushing sleeve 9 is pushed to the left, driving the limiting rod 7 and the conical sleeve 6 to move to the left, compressing the first elastic member 8. Further, the needle can be pushed out by the leftward movement of the conical sleeve 6 to complete the disassembly of the needle. Then, the pushing sleeve 9 is released, and the first elastic member 8 returns to its original state, driving the pushing sleeve 9, the limiting rod 7 and the conical sleeve 6 to move to the right and reset. Subsequently, a new needle is installed on the left side of the syringe barrel 1, and the replacement of the needle is completed.
[0024] It should be understood that the above description is for illustrative purposes only and is not intended to limit the present utility model. Those skilled in the art will understand that variations of the present utility model will be included within the scope of the claims herein.
