Detailed Description

The following detailed description is made with reference to the accompanying drawings.

As shown in fig. 1 to 4, the utility model provides a novel gynecological drug delivery injector, which at least comprises a drug delivery tube 1 and an injection tube 2 which are communicated with each other. The administration tube 1 is used for insertion into the vagina of a patient to inject the drug therein into the vagina of the patient. The injection tube is used to push the drug in the administration tube 1 into the vagina of the patient.

Preferably, administration tube 1 is connected to injection tube 2 in such a way that it can rotate about its own central axis. Specifically, as shown in fig. 1, the syringe 2 is provided with a fixing groove 15 having a ring shape. The administration tube 1 is provided with a third projection 16. The third protrusion 16 is nested in the fixing groove 15, so that the administration tube 1 can rotate around the central axis of the injection tube 2. Preferably, the administration tube 1 is further provided with a plurality of drug discharge holes 17. When the medicine in the administration tube 1 is injected into the vagina of a patient through the medicine discharge hole 17, the medicine can be uniformly distributed in the vaginal wall by rotating the administration tube 1, so that a better treatment effect can be achieved.

Preferably, at least one piston disc 3 is nested in the administration tube 1 in such a way as to be able to slide in the axial direction of the administration tube 1. For example, the inner wall of the administration tube 1 is provided with at least one first sliding groove 4 extending in the axial direction of the administration tube 1. The piston disc 3 is provided with at least one first protrusion 5 which can be nested in the first sliding groove 4. The sliding of the piston disc in the administration tube is achieved by the first protrusion nesting in the first sliding groove 4. And the nesting of the first protrusion and the first sliding groove prevents the piston disc from rotating relative to the administration tube. In the case where the piston disc 3 is rotated about the central axis of the syringe 2 by an external force, the administration tube 1 can be rotated in synchronization with the piston disc 3. Pressure can be applied to the administration tube by sliding of the piston disc, which in turn causes the drug to be expelled from the discharge orifice 17.

Preferably, at least one stirring blade 6 is provided on the piston disc 3 so as to be slidable in the axial direction of the administration tube 1. The piston push rod 7 is arranged on the piston disc 3. At least one fixing rod 8 is connected to the piston disc 3 in such a way as to penetrate both the piston push rod 7 and the piston disc 3. The stirring blade 6 is connected to a fixing rod 8. The piston pusher 7 is nested in the syringe so as to be slidable in the axial direction of the syringe 2. And then the piston disc can slide by pushing and pulling the piston push rod. For example, as shown in fig. 1, when the plunger rod is pushed to the left, it can drive the piston disc to move to the left, thereby expelling the medicine. The rotation of the administration tube can be realized by rotating the piston push rod. When the fixing rod 8 is rotated, the rotation of the stirring blade 6 can be realized, and then the medicine in the administration tube can be stirred and mixed.

Preferably, the fixing rod can be nested in the piston push rod and the piston disc 3 at the same time, so that the fixing rod 8 can slide along the axial direction of the administration tube 1. For example, as shown in fig. 1, when the fixing rod is pushed to the left, it can drive the stirring blade 6 to move to the left, and then the position of the stirring blade can be adjusted to achieve a better stirring effect.

Preferably, the piston pusher 7 is nested in the syringe 2 in such a way as to be able to slide in the axial direction of the syringe 2. Specifically, at least one second sliding groove 9 is provided on the inner wall of the injection tube 2. At least one second protrusion 10 is disposed on the piston rod 7. The second projection 10 is capable of being nested in the second sliding groove 9, thereby enabling the piston pusher 7 to slide in the axial direction of the syringe 2.

Preferably, at least one annular fourth sliding groove 12 and at least one third sliding groove 11 extending in the same direction as the second sliding groove 9 are further provided in the syringe 2. The length of the third slide groove 11 and the length of the second slide groove 9 are different from each other. The second sliding groove 9 and the third sliding groove 11 are both communicated with the fourth sliding groove 12. In the case where the piston pusher 7 slides in the axial direction of the syringe 2 so that the second projection 10 is switched from the first state nested in the second slide groove 9 to the second state nested in the fourth slide groove 12, the second projection 10 can be switched from the second state to the third state nested in the third slide groove 11 in such a manner as to rotate the piston pusher 7. Specifically, as shown in fig. 1, when the second protrusion 10 is nested in the second sliding groove 9, pushing the piston rod 7 leftward can make the second protrusion 10 be nested in the fourth sliding groove 12, and then rotating the piston rod 7 to make the second protrusion 10 rotate to be aligned with the third sliding groove 11, and then pulling the piston rod 7 rightward can make the second protrusion 10 be nested in the third sliding groove 11. Since the lengths of the second sliding groove 9 and the third sliding groove 11 are different from each other, the maximum distance of the piston disc 3 moving to the right can be adjusted, and thus the purpose of quantitative injection can be achieved.

Preferably, the injection tube 2 is further provided with a leakage-proof pad 13. When the administration tube 1 is inserted into the vagina of a patient, the injection tube 2 and the leakage preventive pad 13 are both located outside the vagina. The leakage preventing pad 13 may be a pad body made of cotton or sponge having an adsorption function. Further, when the injected medicine leaks from the vagina, the leaked medicine can be absorbed by the leakage-proof pad 13 to prevent the trousers from being soiled. Preferably, the leakage preventing pad 13 is provided with an adhesive layer 14. The adhesive layer 14 may be a double-sided tape, so that the leakproof pad can be adhered to the vulva of the patient, thereby achieving a better leakproof effect.

Preferably, the administration tube 1 is further provided with at least one drug injection hole 18. The injection hole 18 is provided with a check valve 19. The drug can be injected into the administration tube through the drug injection hole 18. When the piston disc moves to the left, the one-way valve 19 is closed, and thus the discharge of the medicine from the medicine injection hole 18 can be prevented.

It should be noted that the above-mentioned embodiments are exemplary, and those skilled in the art can devise various solutions in light of the present disclosure, which are also within the scope of the present disclosure and fall within the scope of the present disclosure. It should be understood by those skilled in the art that the present specification and drawings are illustrative only and are not limiting upon the claims.
