Description

Syringe sealing sleeve

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to a syringe seal cover is related to.

Background

The syringe is a medical apparatus commonly used in the medical industry nowadays, and is often used for injecting a liquid medicine into a human body, so that the syringe is required to be in a sterile environment to avoid carrying bacteria into the human body. At present, two methods are generally used for extracting liquid medicine by a syringe, one method is a normal medicine extraction method according to the requirements of textbooks: that is, the index finger and the middle finger of one hand clamp the medicine liquid ampoule bottle, the thumb and the ring finger of the same hand clamp the syringe needle cylinder, and the other hand clamps the syringe piston handle to suck the medicine liquid. The method can ensure that the piston rod of the syringe is not touched by foreign objects and can ensure the sanitation of the syringe, but has the defects of complex action and low working efficiency.

Another method is the commonly used hand-held piston method: namely, the ampoule bottle is held by one hand, the syringe needle cylinder is clamped by the thumb and the forefinger of the other hand, and then the ring finger pulls the piston handle to suck the liquid medicine. The efficiency of the method is high, but the hand is easy to touch the piston pull rod, so that the piston rod is polluted by bacteria, and the bacteria on the piston rod can be pushed into the human body along with the liquid medicine, thereby causing serious consequences. Therefore, in order to effectively avoid bacterial contamination, a syringe sealing protective sleeve is needed to protect the syringe piston rod and other parts from contamination.

Solutions are continuously proposed by the skilled person at present. For example, an "environmental protection and contamination prevention syringe protection cover and syringe" disclosed in chinese patent document, whose publication number is CN205235092U, includes a flexible protection film having elastic openings at both ends. Two elasticity open ends of flexible protection film are the syringe cover head end that is used for being connected with the syringe cylinder and the piston pull rod cover head end that is used for being connected with the piston pull rod respectively, can overlap the piston pull rod in the protective sheath, avoid with human contact, but the shortcoming lies in that the protective sheath both ends all have the elasticity opening, and fixed mode is fixed through the rubber band, and the open end can take place to remove when using, misoperation appears. Meanwhile, the protective sleeve is of a non-sealing structure and has hidden dangers, and the protective sleeve can only be used together with a matched injector, so that the condition limitation is large, and the use cost is high.

SUMMERY OF THE UTILITY MODEL

The utility model relates to an overcome among the prior art problem that the hand contact caused the pollution when user of service uses the syringe, provide a syringe seal cover, can guarantee sealed while protection syringe, the hand does not contact with the syringe pull rod when making user of service use syringe, avoids bacterial contamination.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a syringe seal cover, includes an elastic sealing cover, elastic sealing cover is equipped with one and can connects fixed elasticity opening with syringe cylinder rear end cover, and the syringe cylinder rear end and the pull rod of syringe are wrapped to the main part of elastic sealing cover, are close to elastic opening's elastic sealing cover main part and are equipped with the bulge loop with the grip block looks adaptation of syringe rear end, the bulge loop cladding the grip block. The utility model discloses a syringe, including the elasticity seal cover main part, the elasticity opening both ends are handed when installation to the user, avoid touching the pull rod, fix the elasticity opening on the cylinder, the front end and the syringe cylinder of elasticity seal cover main part closely laminate, the rear end is then with the complete cladding of the pull rod of syringe, when the user inhales the liquid medicine in the use, when the pull rod of syringe is pulled out from the cylinder, the elasticity seal cover can extend thereupon, in the extension of elasticity seal cover in-process, the protruding ring closely laminates the holding piece and provides the resistance, prevent that the seal cover from droing, protection through the seal cover, user's hand only can touch the seal cover, thereby avoid touching the syringe pull rod.

Preferably, the inner diameter of the elastic opening of the elastic sealing sleeve is smaller than the outer diameter of the syringe barrel. When the elastic opening of the sealing sleeve is installed, the elastic opening of the sealing sleeve needs to be sleeved on the syringe of the injector, and as the inner diameter of the elastic opening is smaller than the outer diameter of the syringe, certain elastic force can be generated after the elastic opening is installed, so that the sealing sleeve is tightly attached and fixed on the syringe to play a role in fixing.

Preferably, the elastic opening of the elastic sealing sleeve is provided with an inward convex rubber ring. After the sealing sleeve is installed, the elastic opening of the sealing sleeve is attached to the needle cylinder wall through the elasticity of the rubber ring at the elastic opening end, secondary fixation is carried out, the sealing sleeve can not move in the using process, and the sealing function can be achieved.

Preferably, the elastic sealing sleeve is cylindrical, the closed end of the elastic sealing sleeve is provided with a rear ring matched with the push handle at the rear end of the syringe pull rod, so that the tail end of the elastic sealing sleeve can be tightly attached to the syringe push handle, and the syringe push handle and the rear ring are fixed to prevent the syringe sealing sleeve from sliding and deviating in the using process, thereby playing roles in positioning and fixing.

Preferably, the inner diameter of the elastic sealing sleeve at the front part of the raised ring is larger than that at the rear part of the raised ring. The elastic sealing sleeve has the advantages that the sections of the elastic sealing sleeve are matched with the diameters of the needle cylinder and the pull rod, so that the sealing sleeve is convenient to install, the fit clearance between the sealing sleeve and the injector is small, and the sealing effect is improved.

Preferably, the length of the elastic sealing sleeve at the rear part of the convex ring is matched with the shortest length of the pull rod of the injector exposed out of the needle cylinder. The pull rod is pulled by the syringe when the liquid medicine is sucked, the elastic sealing sleeve is extended along with the pull rod, and after the elastic sealing sleeve is extended, a certain thrust can be provided when the syringe injects the liquid medicine, so that the use of a user is labor-saving when the user injects the liquid medicine.

Preferably, the elastic sealing sleeves have various sizes, correspond to different types of syringes and have wide application range.

Therefore, the utility model discloses following beneficial effect has: (1) the syringe can be protected from bacterial contamination; (2) the structure is simple, and the production cost is low; (3) the operation is convenient, simple and effective.
