Automatic suction syringe for tympanocentesis

Abstract

The invention relates to the technical field of medical equipment, and discloses an automatic suction syringe for tympanocentesis, which comprises a syringe body, a circular groove formed in the syringe body, a syringe tube arranged in the circular groove, a piston rod arranged in the syringe tube, an end head arranged at the bottom end of the piston rod, an anti-skid groove formed in the bottom of the syringe body, a battery is arranged in the syringe body, a miniature electric telescopic rod is arranged below the battery, and a fixing block is arranged at the lower end of the miniature electric telescopic rod. According to the automatic suction syringe for tympanocentesis, by arranging the syringe body, the circular groove and the syringe tube, effusion suction can be conducted by holding the syringe body with a hand, the syringe tube can be replaced at will for repeated use, the sanitary requirement of the disposable syringe is met, and waste of redundant materials is avoided; and by arranging the miniature electric telescopic rod, the fixing block, a clamping block and a clamping groove, the purpose of automatically sucking effusion can be achieved, and the trouble of traditional manual effusion sucking and double-hand operation is avoided.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an automatic aspiration syringe for tympanic membrane puncture. Background technique [0002] Secretory otitis media is a non-suppurative inflammatory disease of the middle ear characterized by fluid accumulation (including serous, mucus, and serous-mucus, but not blood or cerebrospinal fluid) in the middle ear often containing the mastoid cavity, intact tympanic membrane, and hearing loss , also known as effusion otitis media. The middle ear is an air-filled space behind the tympanic membrane. When the effusion is very viscous, it is called "glue ear". Typical symptoms are otalgia, hearing loss, ear fullness, and tinnitus. [0003] There are following problems in prior art: [0004] 1. During the operation of the existing tympanic membrane puncture, the operator needs to fix the syringe with the puncture needle with one hand, and pull the piston rod of the syringe wi...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the deficiencies of the prior art, the present invention provides an automatic aspiration syringe for tympanic membrane puncture, which can achieve the purpose of automatic aspiration of effusion, avoid the trouble of traditional manual aspiration and two-handed operation, and is more convenient and comfortable to use. The injection barrel can be replaced at will for repeated use, and the service life is long, which solves the problem that the traditional tympanic membrane puncture syringe needs to be operated with both hands, and other operations cannot be performed. It can only be assisted by an assistant, and it is used for one-time use. , the problem of increasing the financial burden on medical institutions
