Definitions
- the present invention relates to a drug injector, and more particularly, to a drug injector which can be detached at its tip and does not fall off even under high pressure as an injector for local administration used in the medical field and the like.
- Cartridge-mounted injectors and syringe-type injectors are conventionally known as injectors for local administration used in the medical field and the like.
- Cartridge-mounted devices are often used to administer local anesthetics, mainly in the dental field.
- Disposable syringe-type syringes are often used with emphasis on hygiene.They are used for filling containers for bioadhesives during surgical operations in medicine, and containers for periodontal diseases are known in dentistry. ing.
- a method for injecting a drug into a periodontal pocket in order to eliminate periodontal pathogens that proliferated in the periodontal pocket has been disclosed in Japanese Patent Application Laid-Open No.
- the injector disclosed in Japanese Unexamined Patent Publication No. Hei 4-1-17959 determines a nozzle at a position apart from the tip of the nozzle by a length corresponding to the depth of the periodontal pocket, which is a criterion for determining whether or not to inject a drug.
- This is an injector with a marking for use.
- the nozzle is provided at the tip of the syringe body at a predetermined angle with respect to the axis.In use, the injector nozzle is inserted into the periodontal pocket, and the tip is placed at the bottom of the pocket. By observing the judging mark coming out of the pocket while in contact, the drug can be injected. If it is necessary to inject the medicine, the medicine can be injected from the nozzle by pressing the plunger as it is.
- an injector in which a nozzle mounting portion inclined at a predetermined angle is provided at the tip of the syringe body so that a plurality of nozzles having different diameters, Zs, or lengths can be mounted.
- Utility model registration No. 03354544 Utility model registration No. 03354544.
- the nozzle is tapered into a nozzle mounting portion formed in a tape shape, and when a highly viscous material is injected, the nozzle is moved from the nozzle mounting portion during use. It may fall off.
- the tilt angle of the nozzle is specified by the syringe body, if you want to change the angle depending on the injection site, you must replace the syringe body, and it is impossible to respond to the actual angle change is there.
- the present invention has been made in view of the above circumstances, and it is possible to use a nozzle having an appropriate size and angle according to an injection site. By replacing the nozzle, it is possible to prevent infection and use a medicine without waste.
- the purpose is to provide a drug injector. Disclosure of the invention
- the present inventors have conducted intensive studies to solve the above-mentioned problems, and Have completed the present invention by conceiving that a nozzle inclined at a predetermined angle with respect to the base end side may be employed. That is, the present invention provides a barrel provided with a nozzle mounting portion at a tip thereof, a plunger provided at a tip thereof with a gasket capable of sliding the inner wall of the barrel in a liquid-tight manner, and a plunger inserted from the rear end of the barrel.
- the part includes a detachable nozzle
- the nozzle includes a base-side mounting part provided with means for mounting to the nozzle mounting part, and a discharge part that is bent at a predetermined angle from the mounting part and extends. It is a vessel.
- the nozzle mounting portion and the barrel nozzle mounting portion are formed so as to be luer-lockable.
- the nozzle mounting portion is provided on the distal tip that fits into the bore of the nozzle and on the outside of the distal tip.
- a concentric female screw is used, and the female screw is screwed with a male screw provided at the base end of the nozzle.
- the female screw may be formed integrally with the barrel, or may be rotatably provided on the outer wall of the barrel.
- a nozzle including a base-side mounting portion provided with a mounting means to the distal end of the barrel and a discharge portion bent at a predetermined angle from the mounting portion can be applied to a normal syringe.
- FIG. 1 is a longitudinal sectional view showing one embodiment of the present invention.
- FIG. 2 is a longitudinal sectional view showing another embodiment of the present invention. BEST MODE FOR CARRYING OUT THE INVENTION
- FIG. 1 is a longitudinal sectional view showing one embodiment of the present invention
- FIG. 2 is a longitudinal sectional view showing another embodiment.
- the liquid injector according to the present invention, a barrel 1 having a nozzle mounting portion 11 at the tip, It comprises a plunger 2 having a gasket 21 at the tip and a detachable nozzle 3 at a nozzle mounting part 1 1.
- the nozzle 3 is attached to the barrel 1 at a predetermined angle from the mounting part 3 1. It consists of a discharge section 32 that is bent and extends.
- the barrel 1 is a cylindrical container made of a synthetic resin such as polypropylene, polyethylene, or cyclic polyolefin, and has a flange 12 at the base end for hooking a finger during the injection operation, and a nozzle 3 at the tip.
- Nozzle mounting part 11 is provided.
- the nozzle mounting portion 11 is usually provided with a distal tip 1 11 1 which is mounted and fitted in the bore 3 12 of the mounting portion 3 1 of the nozzle 3, and a male screw which will be described later provided at the base end of the nozzle 3. It consists of female screw 1 1 2 that is screwed into 3 1 1.
- the female screw 1 12 is a hood-shaped member provided concentrically outside the tip 111 and may be formed integrally with the barrel 1 as shown in FIG. 1, but as shown in FIG. Thus, the outer wall of the barrel 1 may be rotatably provided so that the direction of the nozzle 3 can be freely changed.
- the tip 111 is normally provided so as to protrude more toward the tip than the female screw 112 as shown in FIGS.
- the plunger 2 is an extrusion member provided with a gasket 21 at the tip of the plunger rod 22, and is inserted from the rear end of the barrel 1.
- the plunger rod 22 is a rod-shaped member formed of a synthetic resin such as polypropylene, polyethylene, polycarbonate, polystyrene, or ABS resin, and has a head 221 at the tip.
- the gasket 21 is a closing member generally formed of a rubber-based material such as butyl rubber or isoprene rubber, and is attached to the head 22 1 of the plunger rod 22 and along the inserted inner wall of the barrel 2. And can slide in a liquid-tight manner.
- the nozzle 3 is a hollow member formed of the same synthetic resin as that of the barrel 1, and has a mounting portion 31 provided with a mounting means for mounting the barrel 1 to the nozzle mounting portion 11, and a predetermined angle bent from the mounting portion 31. And a discharge portion 32 extending. Attachment means to the nozzle attachment part 11 is provided at the base end of the attachment part 31. Normally, male threads 3 1 1 which are coupling means corresponding to female threads 1 12 of the barrel 1 are adopted. .
- the male screw 3 1 1 is usually provided with two axially symmetrical threads (referred to as double-threaded screw; it can be screwed with the female screw 1 1 2 of the K barrel 1).
- the dimensions and the bending angle of the discharge part 32 are determined according to the state of the injection site of the patient.
- the dimension of 32 is 3 to 20 mm, and the bending angle is usually 0 ° to 90 °.
- the entire nozzle 3 may be formed by one shot. However, in order to improve the dimensional accuracy of the discharge portion 32, the entire portion may be formed by insert molding after forming the discharge portion 32.
- the mounting portion 31 and the discharge portion 32 may be formed separately and then bonded together (in this case, the mounting portion 31 must be bent at a predetermined angle at its tip).
- the drug injector according to the present invention is provided as a prefilled syringe having a shape in which the barrel 1 is filled with a drug in advance and the nozzle attachment portion 11 at the tip is closed with a cap (not shown). It is also possible. Industrial applicability
- the drug injector of the present description it is possible to select a nozzle having an appropriate size and a bent angle according to the state of the injection site of the patient during use.
- the nozzle can be replaced when it is reused, infection from the nozzle portion can be prevented.
