Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, and in particular relates to a handheld surgical drug vaginal accurate feeding device. Background Technology

[0002] In recent years, intracavitary drug delivery has become a convenient and effective clinical route of administration. For example, intracavitary drug delivery devices have begun to be used in vaginal, nasal, and other applications. For instance, patent document CN220025869U discloses a handheld surgical drug vaginal delivery device, including a drug injector, a sealing cap, and a lubricating fluid bladder. The drug injector includes an injection cylinder, a gel drug, and a piston-type push rod. The front end of the injection cylinder protrudes forward to form a hemispherical injection head, and a drug extrusion hole is formed on the surface of the hemispherical injection head. The piston-type push rod is fitted inside the injection cylinder. The lubricating fluid bladder is located inside the sealing cap. The sealing cap is movable back and forth on the outside of the front end of the injection cylinder. When the sealing cap is moved back a preset distance, the lubricating fluid bladder is ruptured. Using this patented technology, the overflowing lubricant adheres to the outer surface of the hemispherical injection head. When the hemispherical injection head contacts the vaginal opening and vaginal wall of the female patient, the lubricant provides good lubrication to the vaginal opening and vaginal wall, allowing the injection tube to be inserted into the vagina more smoothly and improving the comfort of the female patient.

[0003] However, existing intracavitary drug delivery devices require direct contact with the human skin during use, which can easily cause skin damage and exogenous infection. In addition, for powder or powder injection drugs, mixing is required before administration, and mixing and administration often require different instruments. During this process, the mixed drug needs to be transferred into the delivery device, which can also easily cause exogenous infection, affecting the patient's medication efficacy. In the existing technology, to prevent exogenous infection of the delivery device, the drug storage area needs to be wrapped or protected with a protective cover when the device is not in use. Existing protective covers are generally made of non-metallic materials with smooth surfaces, making it difficult for users to remove the protective cover when using a handheld surgical drug vaginal delivery device. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a handheld surgical drug vaginal accurate feeding device.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a handheld surgical drug vaginal accurate feeding device, including a handle, a slide, and a protective cover. The protective cover has an opening at one end, while the handle and slide are both open at both ends. The open end of the protective cover covers one end of the handle, and the other end of the handle serves as a limiting platform. One end of the slide is provided with a thrust plate, and the other end of the slide is fixedly connected to a surrounding tube and a guide tube, respectively. The surrounding tube and the guide tube surround each other to form a drug storage chamber. The surrounding tube is also fixedly connected to one end of a pawl. When the slide is fitted into the handle, the other end of the pawl abuts against the inner wall surface of the handle. The surface of the protective cover is also provided with an anti-slip platform.

[0007] The number of pawls is multiple, and the multiple pawls are arranged at equal intervals along the outer circumference of the casing.

[0008] The number of pawls is 4.

[0009] The number of anti-slip platforms is multiple, and the multiple anti-slip platforms are arranged at equal intervals along the outer periphery of the protective cover.

[0010] The number of anti-slip platforms is 6.

[0011] The anti-slip platform is hemispherical in shape.

[0012] The inner wall of the protective cover is also provided with a positioning groove, and the surface of the handle is provided with corresponding protruding teeth. When the open end of the protective cover covers one end of the handle, the protruding teeth are fitted into the positioning groove.

[0013] The beneficial effects of this utility model are as follows: When the drug delivery device is not in use, the protective cover is used to cover the drug storage chamber to prevent the inside of the drug storage chamber from being subjected to exogenous infection and to ensure the efficacy of medication for patients. When the drug delivery device is in use, the protective cover is provided with an anti-slip platform, which makes it easy for the operator to apply a pulling force to the protective cover and remove it. After the medicine is put into the drug storage chamber, the operator applies a pushing force to the slide cylinder, which slides along the handle cylinder axis. The medicine then enters the patient's cavity through the gap between two adjacent pawls, so that the medicine is accurately delivered to the predetermined position, laying the foundation for improving the efficacy of medication for patients.

[0020] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0021] like Figures 1 to 5 As shown, this utility model provides a handheld surgical drug vaginal accurate feeding device, including a handle 1, a slide 2 and a protective cover 3. The protective cover 3 has an opening at one end, while the handle 1 and the slide 2 are both open at both ends. The open end of the protective cover 3 covers one end of the handle 1, and the other end of the handle 1 serves as a limiting platform 4. One end of the slide 2 is provided with a thrust platform 5, and the other end of the slide 2 is fixedly connected to a surrounding cylinder 6 and a guide cylinder 7, respectively. The surrounding cylinder 6 and the guide cylinder 7 surround each other to form a drug storage chamber 8. The surrounding cylinder 6 is also fixedly connected to one end of a pawl 9. When the slide 2 is fitted into the handle 1, the other end of the pawl 9 abuts against the inner wall surface of the handle 1. The surface of the protective cover 3 is also provided with an anti-slip platform 10.

[0022] By employing the technical solution of this utility model, when the drug delivery device is not in use, the drug storage chamber is covered with a protective cover to prevent exogenous infection inside the drug storage chamber and ensure the efficacy of medication for patients. When the drug delivery device is in use, the protective cover has an anti-slip surface, which makes it easy for the operator to apply a pulling force to remove the cover. After the medicine is placed in the drug storage chamber, the operator applies a pushing force to the slide cylinder, causing the slide cylinder to slide along the handle cylinder axis. The medicine then enters the patient's cavity through the gap between two adjacent pawls, ensuring that the medicine is accurately delivered to the predetermined position, thus laying the foundation for improving the efficacy of medication for patients.

[0023] Specifically, there are multiple pawls 9, which are arranged at equal intervals along the outer circumference of the casing 6. Preferably, there are four pawls 9. The pawls 9 and the casing 6 are used to guide the axial sliding of the slide tube 2 relative to the handle tube 1, preventing leakage of the medication if it does not reach the intended position in the patient's cavity.

[0024] In addition, there are multiple anti-slip platforms 10, which are arranged at equal intervals along the outer periphery of the protective cover 3. Preferably, there are six anti-slip platforms 10. The anti-slip platforms 10 are hemispherical in shape. The protective cover 3 is made of non-metallic material. This makes it easy for the operator to remove the protective cover and facilitates its use.

[0025] In addition, the inner wall of the protective cover 3 is provided with a positioning groove 11, and the surface of the handle 1 is provided with corresponding protruding teeth. When the open end of the protective cover 3 is covered with one end of the handle 1, the protruding teeth are fitted into the positioning groove 11.
