Embodiment Construction

[0065] The technical means adopted by the present invention to achieve the predetermined purpose of the invention are further described below with reference to the accompanying drawings and the preferred embodiments of the present invention.

[0066] like Figure 1 to Figure 3 As shown, a preferred embodiment of the metered syringe of the present invention is disclosed, and the metered syringe includes a needle cover set 10, an injection sleeve set 20, an injection push rod set 30 and a metered ring 40.

[0067] like image 3 and Figure 5 As shown, the needle cover set 10 includes a medicine bottle cover 11 and a needle cover 12, one end of the medicine bottle cover 11 has a combined end 111, and the other end has a hollow engaging end 112, so The combined end portion 111 is used for assembling and fixing the bottle end of the medicine bottle 50. An end plate portion with a perforation is formed at the end of the combined end portion 111, and an accommodating groove is for...

Abstract

The invention relates to a counting syringe, which includes a needle set, an injection sleeve set, an injection push rod set and a counting ring. The needle set is used to assemble a medicine bottle, and the injection sleeve set is set on the medicine bottle The outer side is detachably assembled with the needle set, and the injection push rod set is set in the injection sleeve set with its rod body socketed with the counting ring. After each time the counting syringe is filled with a medicine bottle and injected, the needle can be The set and the medicine bottle are disassembled and discarded, and the combination of the injection sleeve set, the injection push rod set and the counting ring can be reused, and the thread groove between the counting ring and the rod body is matched with the interference thread protrusion, and the counting The ratchet groove of the ring is combined with the snap button in the injection sleeve group, so that when the injection push rod group is pulled backward each time the medicine bottle is disassembled, the number of repeated uses is automatically counted. When the preset number of uses is reached, the counting ring It can no longer be rotated, and the injection push rod group cannot be pulled back for use, which avoids excessive repeated use of the counting syringe and ensures safe use.

Description

technical field [0001] The present invention relates to a syringe, in particular to a metered syringe that can be used repeatedly and can remind users to discard it after a certain number of uses. Background technique [0002] When the existing general syringe is used, because all its components are in contact with the drug, based on the safety of injection, all the components of the entire syringe need to be discarded after the syringe is used, so the cost of the syringe for the patient is high. If not, it causes a heavy burden on the treatment, and the amount of waste of the used syringe is too large. [0003] In order to solve the problem that the entire injection must be completely discarded after the existing syringe is used, the applicant of the present invention has previously proposed a syringe that can be partially reused. The syringe mainly utilizes the reusable structure of its main body of the syringe, and only makes the medicine container and needle containing ...
