Problems solved by technology

[0003]Among them, for medical syringes, they are mostly disposable packaging products. It is sealed to make it easy for medical staff to use, and because the needle and the tube body are two single parts, the length of the connection package is too large, which will cause a large number of disposable packaging, that is, A waste of resources has been generated; at the same time, after the syringe is used for one time, it needs to be placed inside the waste barrel for destruction. Furthermore, when the connection and combination of the two single parts of the needle and the tube body form a length Larger appliances and oversized syringes will occupy a lot of space inside the waste bucket, which will make the waste bucket easy to reach full, that is, a certain amount of storage space is wasted

Embodiment 1

[0042] see Figure 1-Figure 6 As shown, the purpose of this embodiment is to provide a retractable syringe based on a sliding connection needle, including a syringe body 100, and the syringe body 100 at least includes:

[0043] The needle adjustment mechanism 110, the needle adjustment mechanism 110 includes a tube body 111, the inside of the tube body 111 is provided with a baffle 112, the inside of the baffle 112 is equipped with an injection needle 113, and the surface of the baffle 112 is provided with a liquid flow port through which the fluid can pass. 1121, the inside of the pipe body 111 is provided with a push plug 114, the surface of the push plug 114 is equipped with a push handle 115, the outside of the pipe body 111 is provided with an adjustment assembly 116, the adjustment assembly 116 includes a mounting plate 1161, the pipe body 111 and the mounting plate 1161 Adjusting screw 1162 is connected in rotation between them, the surface of adjusting screw 1162 is pr...

Embodiment 2

[0051] In order to improve the stable adaptability of the injection needle 113, the difference between this embodiment and Embodiment 1 is that please refer to Figure 7 Shown:

[0052] Wherein, the side wall of the tube body 111 is provided with a concave cavity 1111, and an electric push rod 1112 is installed inside the concave cavity 1111, and a fixed ring 1113 is connected to the top of the electric push rod 1112, and the fixed ring 1113 fits snugly with the surface of the injection needle 113 , wherein, two fixed rings 1113 are symmetrically arranged, and the two fixed rings 1113 are connected through rods, that is, after the position of the injection needle 113 is fitted and fixed by the fixing mechanism 120, the driving of the electric push rod 1112 makes the The fixing ring 1113 moves upwards along the inside of the concave cavity 1111, that is, the inside of the two fixing rings 1113 will fit the injection needle 113, which further strengthens the fixing of the inject...

Embodiment 3

[0055] In order to allow the tube body 111 to be mixed during the preparation of medicines, the difference between this embodiment and Embodiment 1 is that please refer to Figure 8-Figure 9 Shown:

[0056] Among them, to save the time of preparing medicine, the surface of the baffle 112 is provided with a rotating plate 1122, and the other end of the baffle 112 is provided with a driving motor, and the driving motor is rotatably connected with the rotating plate 1122. When preparing medicine, first insert the injection needle 113 into the product to extract the liquid medicine, and then push the push handle 115 to the outside of the tube body 111, so that the push plug 114 is pulled outward, that is, a negative pressure is generated inside the tube body 111, and the injection The needle 113 will gradually extract the medicinal liquid from the outside and place it inside the tube body 111. At this time, the drive motor is turned on by infrared remote control to make it work, a...

Abstract

The invention relates to the technical field of syringes, in particular to a syringe with a retractable needle head based on sliding connection. The syringe comprises a syringe body, the syringe body at least comprises a needle head adjusting mechanism, the needle head adjusting mechanism comprises a tube body, a baffle plate is arranged in the tube body, an injection needle is arranged in the baffle pate, a push plug is arranged in the tube body, a push handle is arranged on a surface of the push plug, an adjusting assembly is arranged outside the tube body, the adjusting assembly comprises a mounting plate, an adjusting screw rod, a guide plate, a guide block, an end plate, a connecting rotary disk and a tube sleeve; and a fixing mechanism is arranged between the tube body and the baffle plate and comprises symmetrically arranged fixing blocks, a fixing lead screw, an offset rod, a fixing column and a clamping plate. A connection size of the tube body and the injection needle is reduced, such that resources of produced medical instruments are saved, the used syringe body can be reduced, that is, the injection needle retracts into the tube body, and an internal area, occupied by the syringe body, of a waste barrel is reduced.

Description

technical field [0001] The present invention relates to the technical field of syringes, in particular to a retractable syringe based on a sliding connection needle. Background technique [0002] A syringe is a relatively common disposable injection device in the medical field. It is often used to prepare medicines and draw blood for medical staff. [0003] Among them, for medical syringes, most of them are disposable packaging products. When the enterprise produces and packs, the needle and the tube body will be fitted and connected and then sealed to make it easier for medical staff to use. There are two single parts between the body, so that the length dimension is too large when connecting and packaging, which will cause a large number of disposable packaging, that is, a waste of resources; at the same time, for syringes in disposable After use, it needs to be placed inside the waste barrel for destruction. Furthermore, when the connection of the two single parts of th...
