Description

Technical Field

[0001] The invention relates to medical equipment application technology, and in particular to a medical care medication device for obstetrics and gynecology. Background Art

[0002] At present, when obstetricians and gynecologists administer drugs into the vagina of women, they usually use tweezers to hold a cotton ball dipped in liquid medicine to administer drugs to women or use an injection device similar to a syringe to administer drugs into the vagina of women. There are the following main disadvantages: 1. The inner wall of the vagina is very delicate. If tweezers or syringes are directly inserted into the vagina, it is easy to cause rupture of the inner wall of the vagina, causing infection and even affecting the health of the fetus; 2. Existing drug delivery devices can only deliver liquid medicine into the vagina, but not tablets; 3. Doctors are prone to trembling when delivering medicine, which increases the pain of patients. In view of this, we propose a medical care drug delivery device for obstetrics and gynecology to solve the above problems. Summary of the invention

[0006] The medicine pushing mechanism is installed inside the syringe and is used by the user to inject the medicine solution or the medicine tablet. The medicine pushing mechanism includes an operating rod and a sealing block fixedly connected to one end of the operating rod.

[0007] Furthermore, the expansion mechanism also includes a support frame fixedly connected to both sides of the syringe, the first extension arm and the second extension arm are rotatably connected to the two support frames respectively, the syringe is movably sleeved inside the first extension arm and the second extension arm, and a rebound mechanism is provided between the first extension arm and the second extension arm and the syringe.

[0008] Furthermore, the rebound mechanism includes a first fixed block fixedly connected to both sides of the syringe, the first extension arm and the second extension arm are fixedly connected to second fixed blocks corresponding to the first fixed block, and a resistance spring is fixedly connected between the second fixed block and the first fixed block.

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Example 1: Please refer to Figure 1-7 , a medical care medication device for obstetrics and gynecology, comprising a syringe 3, and further comprising:

[0024] An expansion mechanism, which is installed at one end of the syringe 3 and is used by the user to expand the vaginal opening. The expansion mechanism includes a first expansion arm 1 and a second expansion arm 2;

[0025] The medicine pushing mechanism is installed inside the syringe 3 and is used by the user to inject the medicine solution or the medicine tablet. The medicine pushing mechanism includes an operating rod 5 and a sealing block 6 fixedly connected to one end of the operating rod 5 .

[0026] In this embodiment, the expansion mechanism also includes a support frame fixedly connected to both sides of the syringe 3, the first extension arm 1 and the second extension arm 2 are rotatably connected to the two support frames respectively, the syringe 3 is movably mounted inside the first extension arm 1 and the second extension arm 2, and a rebound mechanism is provided between the first extension arm 1 and the second extension arm 2 and the syringe 3.

[0027] In this embodiment, the rebound mechanism includes a first fixed block 10 fixedly connected to both sides of the syringe 3, and the first extension arm 1 and the second extension arm 2 are respectively fixedly connected to the second fixed block 9 corresponding to the first fixed block 10, and a resistance spring 11 is fixedly connected between the second fixed block 9 and the first fixed block 10.

[0028] In this embodiment, the medicine pushing mechanism also includes a pushing rod 7 fixedly connected to one side of the sealing block 6, and a plurality of retaining rings 8 are fixedly connected to an internal array at one end of the syringe 3, and the cross-section of the plurality of retaining rings 8 is arc-shaped. An injection head 4 is threadedly connected to one end of the syringe 3, and the injection head 4 is movably mounted inside the first extension arm 1 and the second extension arm 2.

[0029] In this embodiment, one end of the cross section of the first extension arm 1 and the second extension arm 2 is elliptical, and the cross section of the sealing block 6 is truncated cone.

[0030] Working principle: During use, when it is necessary to inject a tablet, the injection head 4 is removed, and then the tablet is placed inside the syringe 3, and the tablet is clamped and fixed by the clamp ring 8. After the tablet is placed, the first extension arm 1 and the second extension arm 2 are closed by the resistance spring 11, and the medical staff places the closed first extension arm 1 and the second extension arm 2 into the patient's vagina. After placement, the medical staff presses one end of the first extension arm 1 and the second extension arm 2 to make the first extension arm 1 and the second extension arm 2 flip to expand the patient's vagina. At the same time, the medical staff drives the sealing block 6 to move by pressing the operating rod 5, and at the same time, the pushing rod 7 contacts the tablet. The continuous movement of the operating rod 5 pushes the tablet out through the pushing rod 7, so that it falls into the patient's vagina.

[0031] After the tablet is injected, release one end of the first extension arm 1 and the second extension arm 2 to close the first extension arm 1 and the second extension arm 2 through the resistance spring 11, so that the device is taken out from the patient's vagina. When the drug solution needs to be injected, install the injection head 4, and draw the drug solution into the inside of the syringe 3 through the operating rod 5. During injection, the drug solution is injected into the patient's vagina by opening the first extension arm 1 and the second extension arm 2 and pressing the operating rod 5.

[0032] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
