[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-5 This utility model provides a technical solution: an injection aspiration aid for sealing and pushing a syringe to administer medication, comprising a gripping part 1, a pressing part 2, and a pusher block 7. The syringe is placed on the gripping part 1, and the pressing part 2 is integrally connected to the upper end of the gripping part 1. A piston rod is placed inside the pressing part 2, and the pusher block 7 is slidably connected inside the pressing part 2. Medication is administered by applying external force to the pressing plate of the piston rod on the pressing part 2 via the pusher block 7. The operation process seals the piston rod, improving the problem of easy hand contact with the piston rod causing contamination.

[0021] This application provides a detailed structural description in conjunction with the accompanying drawings: The gripping part 1 is configured as an arc-shaped plate, and the arc-shaped groove at the top is a cylindrical groove 101, which is used to place the syringe.

[0022] The pressing part 2 is a hollow cylindrical structure, including a sealing cover 3 and a base 4 for sealing and opening / closing. The upper and lower edge plates of the base 4 are respectively provided with notches 401 on both sides. The sealing cover 3 is an arc-shaped plate, and the upper and lower ends are integrally connected to an arc-shaped base 5. The two ends of the base 5 are arc-shaped protrusions, forming protruding plates 501. One side of the protruding plate 501 is inserted into the notch 401 on one side of the base 4 and is hinged and rotated; the other side of the protruding plate 501 is movably inserted into the notch 401 on the corresponding side, so that the sealing cover 3 can be hinged and rotated on the base 4, and can be opened and closed flexibly.

[0023] In this embodiment, the end of the base 4 is integrally connected to the end of the gripping part 1 and is connected to the cylindrical groove 101. The lower end notch 401 of the base 4 is located at the upper edge of the gripping part 1, so that the piston rod on the injection cylinder can extend into the base 4 along the cylindrical groove 101 and be sealed by the sealing cover 3, that is, the piston rod is movable and sealed on the base 4.

[0024] like Figure 2 As shown, the horizontal wing plate at the end of the syringe is inserted into the lower notch 401 of the base 4. When the corresponding base 5 is inserted here, the protruding plate 501 presses against the end wing plate of the syringe and fixes it to the end of the gripping part 1 for limiting and fixing, which is convenient for use.

[0025] The booster block 7 includes a retaining plate 701. A slot 702 for inserting a piston rod pressing plate is provided in the middle of the retaining plate 701. A retaining ring groove 703 for the piston rod to pass through is provided in the upper part of the retaining plate 701, forming a slot 702 for engaging and placing the piston rod pressing plate.

[0026] The booster block 7 is slidably connected within the base 4. The inner bottom surface of the base 4 is horizontally set, and a sliding groove 9 is formed in the middle, which is rectangular. The booster block 7 includes a limiting plate 704 and an integrated connecting plate 701, which together form an L-shape. The limiting plate 704 is horizontally attached to the inner bottom surface of the base 4. A sliding plate 705 is integratedly connected to the bottom of the limiting plate 704. The sliding plate 705 is slidably connected within the sliding groove 9. The sliding plate 705 is set in a rectangular plate shape to cooperate with the sliding groove 9, and can move along the guide of the sliding groove 9.

[0027] Note: The width of the limit plate 704 is greater than the width of the slide groove 9, so it will not fall out.

[0028] Furthermore, one end of the sliding plate 705 protrudes from the slide groove 9 to the outside. A sliding part 8 is integrally connected to the protrusion of the sliding plate 705. The sliding part 8 is set as a strip-shaped handle, perpendicular to the bottom surface of the base 4, and the diameter of the handle is greater than the width of the slide groove 9. That is, a sliding part 8 for applying force to push the pusher block 7 is set outside the base 4. In conjunction with the sliding plate 705, the plate 701 is pushed on the base 4 and guided to move along the slide groove 9, which can push the piston rod into the injection cylinder.

[0029] As a further improvement to this embodiment, in order to ensure the sealing stability of the sealing cover 3, a locking part 6 is provided between the sealing cover 3 and the base 4; The locking part 6 includes a locking plate 601, which is rectangular and vertically integrated into the middle of the edge of the opening end of the sealing cover 3. A locking tooth 602, a right-angled triangle, is integrally connected to the locking plate 601, with its horizontal surface facing upwards. A locking groove 603, which engages with the locking plate 601, is formed on the edge of the base 4. A second locking tooth 604, also a right-angled triangle, is integrally connected to the inner wall of the locking groove 603, with its inclined surface facing the inclined surface of the first locking tooth 602, allowing it to hook and lock horizontally after being pressed. A protruding unlocking plate 605, horizontally arranged, is integrally connected to the outer wall of the locking groove 603. Pressing the unlocking plate 605 deforms the edge of the base 4, causing the second locking tooth 604 to move outwards and release the constraint on the first locking tooth 602, thus opening the sealing cover 3. The above locking structure has already been used in the lids of wet wipe packs. It is applied here in accordance with clinical needs for ease of operation.

[0030] In use, rotate to open the sealing cover 3, install the syringe accordingly, place the syringe barrel in the barrel groove 101 of the grip part 1, insert the wing plate at the end of the syringe barrel into the lower notch 401 of the base 4, and insert the piston rod pressing plate into the slot 702 of the pusher block 7 to fix the piston rod pressing plates in the middle and tail of the syringe. Then close the sealing cover 3 to seal and lock the piston rod. The medical staff places their hand on the grip part 1, presses the handle at the sliding part 8 with their thumb, and pushes the pusher block 7 to move down along the guide of the slide groove 9, which drives the piston rod to move and push the drug in the syringe barrel for drug administration. This creates a sealed environment and improves the problem of easy contact with the piston rod by hand during operation, which can cause contamination.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
