Description

Technical Field

[0001] The utility model relates to the technical field of medical auxiliary instruments, and more specifically to a novel non-contact medicament suppository pusher. Background Art

[0002] Vaginitis and cervicitis are common diseases in clinical gynecology. In clinical treatment, the main method is to directly administer drugs into the vagina. In the existing technologies such as the treatment of hemorrhoids in anorectal surgery and the application of analgesic suppositories, drugs are directly administered by finger pushing. This is very likely to cause cross-infection and increase pain for patients. Moreover, it is difficult to control the depth of drug administration during such operation, resulting in incomplete treatment. In addition, if the finger pushing method is not properly performed, it may cause dry pain or foreign body sensation for the patient. In response to this, the inventor has proposed a novel non-contact medicament suppository pusher. The suppository and the pusher are integrated. The medicament suppository is pushed in through the guide rod of the pusher to achieve non-contact pushing. The front end of the pusher adopts a smooth and round structure design, and the rear end is provided with scales, avoiding the foreign body sensation and discomfort during insertion, being non-contact, clean and hygienic. At the same time, the insertion position is accurate, which can maximize the drug effect.

[0003] In order to facilitate the insertion of the medicament suppository, with accurate insertion, and at the same time being non-contact and avoiding infection, Chinese Patent (Authorization Publication No.: CN205268807U) discloses a simple gynecological drug dispenser. The utility model includes a mandrel, a drug delivery head and a sleeve. One end of the mandrel is fixedly equipped with the drug delivery head, and the other end of the mandrel is fixedly equipped with an operating handle. The drug delivery head is a conical cylinder, a medicine bin is arranged on the drug delivery head, a medicine bin cover is slidably arranged on the medicine bin opening, and the medicine bin cover is fixedly connected with the sleeve. The utility model has a simple structure. During the drug administration process, the drug can be wrapped by the drug delivery head arranged at the end, and the drug can be accurately delivered to the lesion site through the scale value, solving the drawback of easy cross-infection caused by the existing method of directly administering drugs by finger pushing, and is applicable to the administration of granular drugs and suppository drugs.

[0004] There are still some deficiencies in the application of this solution. Since the sizes of medicament suppositories are different for different diseases, if the size of the drug delivery head is fixed, it is very easy to occur that the diameter of the medicament suppository is too large to be pushed out, or the diameter is too small and it will directly slide out of the drug delivery head, which is not conducive to drug administration. In addition, the portability of the pusher needs to be considered. Now many patients carry it with them and operate it independently. Therefore, it is necessary to improve the structure of the medicament suppository pusher so that it can be applicable to suppositories of different sizes, improve the applicability, ensure the compact structure of the medicament suppository pusher, be convenient to carry and operate, and further improve the practicality.

[0020] The specific implementation of the present utility model will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown, a novel contactless medicine plug pusher comprises a cylinder 1 and a push rod 2, wherein the front section of the cylinder 1 is provided with a placement groove 3, the placement groove 3 is used to place the medicine plug and the front end is provided with a hemispherical drug delivery head 4, the drug delivery head 4 is composed of a plurality of arc-shaped spring pieces 5, the rear section of the cylinder 1 is provided with a hand grip 6, the inner side of the hand grip 6 is provided with a push groove 7 which passes through from front to back, the push rod 2 comprises a front abutment portion 21 and a rear abutment rod 22, the abutment portion 21 is movably embedded in the push groove 7, the rear end of the push groove 7 is provided with a limit ring 8, the middle section of the push rod 22 is correspondingly provided with a limit block 9, the limit block 9 is adapted to the limit ring 8.

[0022] Furthermore, a scale 11 is provided in the middle section of the cylinder body 1.

[0023] Furthermore, a threaded groove is provided at the rear side of the abutting portion 21, and a thread is provided at the front side of the push rod 22, and the thread is movably screwed into the threaded groove.

[0024] Furthermore, a rubber ring 23 is provided on the outer side of the abutting portion 21.

[0025] Furthermore, a lubricant 10 is provided in the front 2 / 3 section of the cylinder body 1.

[0026] Furthermore, several pieces of the arc-shaped elastic pieces 5 are in an inverted "L" shape structure, and the ends gather towards the middle, forming a circular opening 51 in the middle.

[0027] Furthermore, the outer side wall of the front end of the abutting portion 21 abuts against the inner side wall of the drug delivery head 4.

[0028] [Embodiment]

[0029] First, a medicated suppository is placed in the placement groove 3. When it is necessary to push the medicated suppository into the vagina, the thread of the push rod 22 is screwed tightly into the threaded groove of the abutting portion 21. Then, the cylinder body 1 is inserted into the vagina, and the insertion depth can be known in real time through the scale 11 in the middle section of the cylinder body 1. Since the lubricant 10 is provided in the front 2 / 3 section of the cylinder body 1, discomfort can be avoided. After the cylinder body 1 is inserted, the push rod 22 is pushed forward. The push rod 22 drives the abutting portion 21 to move forward from the push groove 7 of the cylinder body 1 and abut against the medicated suppository. Continuing to push forward, the medicated suppository is pushed out from the drug delivery head 4 through the abutting portion 21. Finally, since the drug delivery head 4 is composed of several pieces of arc-shaped elastic pieces 5 and a circular opening 51 is formed in the middle, the medicated suppository is pushed out from the circular opening 51 and clamped by the arc-shaped elastic pieces 5. When the push rod 22 is pushed until the limiting block 9 abuts against the limiting ring 8 of the push groove 7, at this time, the outer side wall of the front end of the abutting portion 21 also abuts against the inner side wall of the drug delivery head 4, and the medicated suppository is completely pushed out. The arc-shaped elastic pieces 5 are reset, and the cylinder body 1 can be pulled out from the vagina. The operation is simple.
