Description
Technical Field
The utility model belongs to the field of medical equipment, relate to the connecting device who shifts the medicine to among the needleless injector ampoule particularly.
Background
With the continuous improvement of living standard of people, the application of the needleless injector is more and more extensive in the life of people, and the common medicine suction connecting device of the needleless injector has some problems, such as the fact that a stainless steel needle tube of a puncture medicine bottle is exposed outside, an operator is stabbed, the needle tube is broken and other adverse factors, and the demand of people on the medicine suction connecting device can not be met gradually. The foreign reports show that the number of medical staff stabbed by needles or medical sharp instruments reaches 80 million and nurses stab 80 to 100 million times each year among 440 million medical staff in the United states; the situation in China is not optimistic: the increasing number of cases of infection due to unsafe injections causes a direct economic loss, and 87.5% of nurses experience sharp-needle puncture. It also causes more serious harm to the health of the patient.
The medicine shifts connecting device is the appurtenance when cooperation needleless injection system injects, and the end of puncturing and screw thread medicine bottle rely on screw thread self revolving force to link to each other, and the other end relies on material self-lubricating property to link to each other with needleless injection system ampoule, makes the medicine shift to in the ampoule through pulling the piston in the ampoule. Fundamentally has solved traditional medicine and has shifted connecting device's acupuncture risk, syringe fracture and handle the environmental problem that medical waste such as disposable syringe brought to have cross infection, a great deal of advantage such as convenient, high-efficient.
The existing needleless injector medicine transfer connecting devices on the market are all stainless steel needle tubes exposed outside, so that potential safety hazards exist. The drug transfer connection device of part of the products is inconvenient to operate, and the operation and experience of a user are affected.
SUMMERY OF THE UTILITY MODEL
The utility model provides a medicine shifts connecting device, medicine shift connecting device at first puncture end and screw medicine bottle swivelling joint, and the needle tubing passes through the rotatory distance puncture medicine bottle of screw thread during swivelling joint, and rotatory to the end, the completion medicine shifts connecting device and is connected with the medicine bottle, has guaranteed user's safe instrument of using.
The technical scheme of the utility model is specifically implemented as follows:
the utility model discloses a medicine shifts connecting device, needle file (1) including connecting gradually, plastics puncture needle tubing (2), UV glues (3), plastics puncture needle tubing (2) are located the guide way bottom of needle file (1), spacing arch has been set for in the needle file guide way, plastics puncture needle tubing is connected with the needle file is glued with UV, UV glues the solidification back and is enough to this guarantee drawing power of going on between plastics needle tubing and the needle file with the spacing protruding formation of needle file, establish the needle file block on needle file (1), ampoule (5) nozzle end links to each other with needle file (1) open end, ampoule (5) and the laminating of spacing arch of ampoule (1-3). The needle seat cover cap is opened, the needle seat and the ampoule bottle of the needleless injector are in self-lubricating sealing connection by virtue of the material performance of the needle seat, and good operation hand feeling is kept.
Compared with the prior art, the utility model has the advantages of it is following:
1. most of the existing medicine transferring and connecting devices in the market are stainless steel needle tubes exposed outside, so that potential safety hazards exist; the plastic puncture needle tube is positioned at the bottom of the guide groove of the needle base, and the needle tip of the needle tube is not higher than the needle base after being fixed by the UV glue, so that puncture injury is effectively prevented;
2. most of the prior ampoule bottles of needleless injectors are connected with the medicine transfer connecting device in a rotating way, which causes troubles for users. And the utility model discloses a medicine shifts connecting device, needle file and needleless injector ampoule rely on needle file material self-lubricating property to carry out sealing connection, convenient to use, easy operation is felt well, and the reliability is high, better service doctor, patient safety are used instrument.

Detailed Description
The technical solution of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1-3, a drug transfer attachment device is designed. The disposable ampoule puncture needle comprises a plastic puncture needle tube (2), a needle seat (1), UV glue (3), a positioning end (2-1) of the plastic puncture needle tube, a needle seat cap (1-1), a UV glue limiting protrusion (1-2) of the needle seat, an ampoule bottle limiting protrusion (1-3) and a medicine bottle positioning inclined plane (1-4).
As shown in fig. 1, the screw-type medicine bottle (4) enables the puncturing end of the plastic puncturing needle tube (2) to be aligned with the central point of the bottle stopper of the screw-type medicine bottle (4) through the needle seat medicine bottle positioning inclined plane (1-4), so that the rigidity of the plastic puncturing needle tube (2) is ensured; the screw-mouth medicine bottle (4) or the needle seat (1) is rotated, the plastic puncture needle tube (2) punctures the bottle stopper of the screw-mouth medicine bottle (4) by means of the self-rotating force of the screw thread, and the puncture is completed by screwing; as shown in fig. 3, the needle base cap (1-1) is opened, the nozzle end of the ampoule bottle (5) is connected with the opening end of the needle base (1), a certain force is applied to enable the ampoule bottle (5) to move forwards until the ampoule bottle is attached to the ampoule bottle limiting protrusion (1-3), the core rod of the ampoule bottle (5) is pulled to enable the medicine to be drawn into the ampoule bottle (5) from the medicine bottle (4) through the medicine transfer connecting device, and medicine transfer is completed.
