Abstract
Description
[0001] This application is a divisional application of application number 202421583053.6. The original application was filed on July 5, 2024, and the original invention was entitled "A Safe Visual Nebulizer for Extracting Medicine". Technical Field
[0002] This utility model relates to the field of medical device technology, specifically to a visual anti-misconnection atomized drug extraction device that can prevent the injection of atomized drugs into the human body. Background Technology
[0003] A syringe is a commonly used medical device consisting of a barrel, piston, and needle. It is used to draw or inject liquids or gases. When the piston is pulled out, the liquid or gas is drawn into the barrel from the needle, and when the piston is pushed in, the liquid or gas is expelled from the barrel.
[0004] Clinically, syringes are commonly used to inject medications into the human body, either through direct subcutaneous injection via skin puncture or intravenous injection via indwelling needles. Nebulization therapy utilizes a nebulizer to disperse medication into tiny droplets or particles, suspending them in a gas that enters the respiratory tract and lungs through respiration, thereby achieving therapeutic effects. A syringe is also required when injecting nebulized medication into the nebulizer; typically, the syringe is first used to draw the nebulized medication from the ampoule and then inject it into the nebulizer.
[0005] In clinical nursing practice, some hospitalized patients require simultaneous injection and nebulizer therapy, a situation commonly seen in respiratory medicine departments. When caring for these patients, medical staff typically prepare the necessary injection and nebulizer medications beforehand and then use a trolley to bring them to the bedside. The problem is that it's difficult to distinguish between syringes used for injections and syringes used for nebulizers. Clinically, there have been instances where medical staff have mistakenly administered nebulizer medications instead of injections due to negligence. Nebulizer medications should never be injected into the human body; incorrect injection can harm the patient and, in severe cases, endanger their life.
[0006] To prevent such errors from occurring, a safe drug extraction device needs to be designed to prevent accidental injection of nebulized medication into the human body. Utility Model Content
[0007] Therefore, the technical problem to be solved by this utility model is to overcome the technical defect that the syringes used for injecting drugs and the syringes used for drawing nebulized drugs in the prior art are basically the same, which will cause serious harm to the health of patients if medical staff accidentally inject nebulized drugs into the patient's body when caring for the patient. Thus, a visual anti-misconnection nebulized drug drawer that can prevent the injection of nebulized drugs into the human body is provided.
[0008] Therefore, this utility model provides a visual anti-misconnection atomizing drug dispenser, comprising:
[0009] The main body for drawing medicine includes a medicine drawing cylinder with one end open and a mounting base disposed at the other end of the medicine drawing cylinder. The mounting base communicates with the inner cavity of the medicine drawing cylinder. A first limiting structure is provided on the mounting base.
[0010] The drug-drawing piston has one end inserted into the inner cavity of the drug-drawing cylinder from the open end of the drug-drawing cylinder, and slides and seals against the inner wall of the drug-drawing cylinder.
[0011] The aspiration needle includes a needle holder that can be detachably connected to the mounting base and a needle body installed at one end of the needle holder; the needle holder is provided with a second limiting structure that can be installed in conjunction with the first limiting structure, and the needle holder can only be connected to the mounting base after the second limiting structure is matched and docked with the first limiting structure.
[0012] Furthermore, the mounting base includes a papillary tube communicating with the inner cavity of the drug extraction cylinder and a first limiting structure formed on the outer peripheral wall of the papillary tube;
[0013] The needle holder has a socket cavity and a second limiting structure formed on the inner peripheral wall of the socket cavity.
[0014] Furthermore, the first limiting structure is a limiting rib; the second limiting structure is a limiting slot, and the limiting rib can be matched and inserted into the limiting slot.
[0015] Furthermore, there are at least two limiting ribs, which are evenly distributed along the outer peripheral wall of the nipple tube; there are at least two limiting slots, which are evenly distributed along the inner peripheral wall of the socket cavity, and their positions are opposite to the positions of the limiting ribs.
[0016] Furthermore, including:
[0017] The main body for drawing medicine includes a medicine-drawing tube that is open at one end;
[0018] The drug-drawing piston has one end inserted into the inner cavity of the drug-drawing cylinder from the open end of the drug-drawing cylinder, and slides and seals against the inner wall of the drug-drawing cylinder.
[0019] The drug extraction needle is integrally formed with the other end of the drug extraction tube.
[0020] Furthermore, the drug-drawing needle has a slender conical structure, and the connection between the drug-drawing needle and the drug-drawing tube forms an arc-shaped transition.
[0021] Furthermore, the drug-drawing needle is made of plastic.
[0022] Furthermore, the tip of the drug-drawing needle is blunt.
[0023] Furthermore, the outer wall of the drug extraction cartridge is provided with colored scale lines.
[0024] Furthermore, an identification label is provided on the outer wall of the drug extraction cartridge.
[0025] The technical solution provided by this utility model has the following advantages:
[0026] This utility model discloses a visual anti-misconnection nebulized drug dispenser, comprising a drug dispensing body, a drug dispensing piston, and a drug dispensing needle. The drug dispensing body includes a drug dispensing cylinder with one open end and a mounting base disposed at the other end of the drug dispensing cylinder, the mounting base communicating with the inner cavity of the drug dispensing cylinder. A first limiting structure is provided on the mounting base. One end of the drug dispensing piston is inserted into the inner cavity of the drug dispensing cylinder from the open end of the drug dispensing cylinder and slides in a sealing contact with the inner wall of the drug dispensing cylinder. The drug dispensing needle includes a needle seat that can be detachably connected to the mounting base and a needle body mounted on one end of the needle seat. A second limiting structure is provided on the needle seat that can be installed in conjunction with the first limiting structure, and the needle seat can only be connected to the mounting base after the second limiting structure matches and mates with the first limiting structure.
[0027] This invention relates to a visually designed, anti-misconnection nebulizer, which, by incorporating a first limiting structure on the mounting base and a second limiting structure on the needle hub, allows medical personnel to easily distinguish it from existing syringes, thus preventing them from using the nebulizer for human injection. Furthermore, the first limiting structure on the mounting base prevents it from connecting with existing indwelling needles, thereby avoiding the use of the nebulizer to inject nebulized medication into the body via an indwelling needle.
[0028] This utility model also provides a visual anti-misconnection atomized drug extractor, including a drug extractor body, a drug extractor piston, and a drug extractor needle; the drug extractor body includes a drug extractor cylinder with one end open; one end of the drug extractor piston is inserted into the inner cavity of the drug extractor cylinder from the open end of the drug extractor cylinder and slides in a sealing contact with the inner wall of the drug extractor cylinder; the drug extractor needle is integrally formed with the other end of the drug extractor cylinder.
[0029] This invention relates to a visually designed, anti-misconnection nebulizer, which integrates the extraction needle and the other end of the extraction cartridge into a single unit. This allows medical personnel to easily distinguish it from existing syringes, preventing them from using the device for human injection. Furthermore, because the extraction needle and the other end of the extraction cartridge are integrally formed, the needle cannot be removed from the cartridge, preventing the device from being connected to existing indwelling needles. This avoids the need for medical personnel to use the device to inject nebulized medication into the body via an indwelling needle. Additionally, the integrally formed extraction needle is made of plastic, making it unsuitable for subcutaneous punctures and thus preventing drug injection. Attached Figure Description

[0040] The present application will now be described in detail with reference to the accompanying drawings and embodiments. Example 1
[0041] This embodiment provides a visual anti-misconnection atomized drug extraction device, such as... Figure 1-4 As shown, the device includes a drug-drawing body 1, a drug-drawing piston 2, and a drug-drawing needle 3. The drug-drawing body 1 includes a drug-drawing cylinder 11 with one open end and a mounting base 12 disposed at the other end of the drug-drawing cylinder 11. The mounting base 12 communicates with the inner cavity of the drug-drawing cylinder 11. A first limiting structure 121 is provided on the mounting base 12. One end of the drug-drawing piston 2 is inserted into the inner cavity of the drug-drawing cylinder 11 from the open end and slides in a sealing contact with the inner wall of the drug-drawing cylinder 11. The drug-drawing needle 3 includes a needle seat 31 that can be detachably connected to the mounting base 12 and a needle body 32 installed at one end of the needle seat 31. A second limiting structure 311 that can be installed in conjunction with the first limiting structure 121 is provided on the needle seat 31, and the needle seat 31 can only be connected to the mounting base 12 after the second limiting structure 311 is matched and docked with the first limiting structure 121.
[0042] This embodiment of the visual anti-misconnection nebulizer extractor, by providing a first limiting structure 121 on the mounting base 12 and a second limiting structure 311 on the needle holder 31, allows medical personnel to easily distinguish it from existing syringes by appearance, thereby preventing medical personnel from using the extractor for human injection. Furthermore, because the first limiting structure 121 is provided on the mounting base 12, it prevents the mounting base 12 from being connected to existing indwelling needles, thus avoiding medical personnel using the extractor to inject drugs into the human body through an indwelling needle.
[0043] In this embodiment of the visual anti-misconnection atomized drug drawer, the mounting base 12 further includes a nipple tube 122 communicating with the inner cavity of the drug drawer 11 and a first limiting structure 121 formed on the outer peripheral wall of the nipple tube 122; the needle seat 31 is provided with a socket cavity 312 and a second limiting structure 311 formed on the inner peripheral wall of the socket cavity 312.
[0044] In this embodiment of the visualized anti-misconnection atomized medicine dispenser, the first limiting structure 121 is a limiting rib; the second limiting structure 311 is a limiting slot, and the limiting rib can be fitted into the limiting slot. In this embodiment, the cross-sectional shape of the limiting rib can be square, circular, semi-circular, triangular, or trapezoidal, etc., and correspondingly, the cross-sectional shape of the limiting slot can also be square, circular, semi-circular, triangular, or trapezoidal, etc.
[0045] In this embodiment of the visualized anti-misconnection atomized drug dispenser, the limiting ribs are further provided in that there are at least two ribs, evenly distributed along the outer peripheral wall of the nipple tube 122; and at least two limiting slots are provided in that they are evenly distributed along the inner peripheral wall of the socket cavity 312, with their positions opposite to the positions of the limiting ribs. In this embodiment, the number of limiting ribs is at least two, but can also be three, four, or five, etc., and correspondingly, the number of limiting slots can also be three, four, or five, etc.
[0046] In this embodiment of the visual anti-misconnection nebulizer, the outer wall of the extraction cylinder 11 is further provided with colored scale lines 111. In this embodiment, by providing colored scale lines 111 on the outer wall of the extraction cylinder 11, the extraction device of this embodiment can be further distinguished from existing syringes, and it is also beneficial for medical personnel to further identify it.

[0048] This embodiment provides a visual anti-misconnection atomized drug extraction device, such as... Figure 5 As shown, it includes a drug-drawing body 1, a drug-drawing piston 2, and a drug-drawing needle 3; the drug-drawing body 1 includes a drug-drawing cylinder 11 with one end open; one end of the drug-drawing piston 2 is inserted into the inner cavity of the drug-drawing cylinder 11 from the open end of the drug-drawing cylinder 11 and slides in a sealing contact with the inner wall of the drug-drawing cylinder 11; the drug-drawing needle 3 is integrally formed with the other end of the drug-drawing cylinder 11.
[0049] This embodiment of the visual anti-misconnection nebulizer drawer, by integrally molding the drawer needle 3 with the other end of the drawer cartridge 11, allows medical personnel to easily distinguish it from existing syringes, thereby preventing them from using the drawer for human injection. Furthermore, because the drawer needle 3 and the other end of the drawer cartridge 11 are integrally molded, the drawer needle 3 cannot be removed from the drawer cartridge 11. This prevents the drawer from being connected to existing indwelling needles, thus avoiding the use of the drawer to inject medication into the body via an indwelling needle.
[0050] In this embodiment of the visualized anti-misconnection atomized drug extractor, the drug extraction needle 3 is a slender conical structure, and an arc-shaped transition 321 is formed at the connection between the drug extraction needle 3 and the drug extraction cylinder 11.

[0052] In this embodiment of the visualized anti-misconnection nebulizer, the tip of the aspiration needle 3 is blunt. In this embodiment, the blunt tip of the aspiration needle 3 prevents it from puncturing human skin, thus further preventing medical personnel from using the aspiration device of this embodiment for human injection.
[0053] In this embodiment of the visual anti-misconnection nebulizer, the outer wall of the extraction cylinder 11 is further provided with colored scale lines 111. In this embodiment, by providing colored scale lines 111 on the outer wall of the extraction cylinder 11, the extraction device of this embodiment can be further distinguished from existing syringes, and it is also beneficial for medical personnel to further identify it.
[0054] In this embodiment of the visual anti-misconnection nebulizer, the drug dispenser further includes an identification label 112 on the outer wall of the drug dispenser cartridge 11. In this embodiment, the identification label 112 is marked with text, graphic symbols, or numbers to identify the purpose of the drug dispenser, or to identify the name of the drug contained inside, usage precautions, etc.
[0055] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this innovative technical solution.
