CN201213969Y - Fixation protection cover of needle tube - Google Patents

Abstract

The utility model discloses a fixed protective sleeve for a needle tube, which mainly comprises a body, wherein an observation window is arranged on the body, and the upper end of the body is provided with a shielding cap. The fixed protective sleeve for the needle tube is characterized in that internal threads which are tallied with the outside diameter of the needle tube are arranged on a joint between the shielding cap and the body. The fixed protective sleeve for the needle tube has a reasonable structure and skillful concept, reduces the radiation to a doctor because the shielding cap is taken as a shield between the doctor and liquid medicine of a needle, effectively increases the direct friction force between the needle tube and the protective sleeve, has the function of fixing the needle tube because the internal threads which are tallied with the outside diameter of the needle tube are arranged on the joint between the shielding cap and the body, shortens the operating time, meets the conditions of external irradiation protection for shortening the irradiated time as possible and arrangement of a shield between a person and a radiation source, reveals the people-oriented spirit, and has promotion value.

Description

Fixed protection sleeve of needle tube

Technical field

This utility model relates to medical container technical field, specifically, relates to a kind of preventer when extracting medical isotope medicament.

Background technology

In the prior art, the producer of production isotope medicament packs active medicament earlier in the cillin bottle, and then the cillin bottle that radiopharmaceutical agent will be housed moves in the cask flask of lead material making, be transported to hospital by manually lifting: after the medical worker opens cask flask then, give service for patients with the medicament that syringe extracts in jar interior cillin bottle.In extraction process, can be subjected to the radiation of doses unavoidably.Adopted needle tube protecting sleeve specially for this reason.But in use, because the structure of this protective jacket is not easy to having an effect of hand, can increase the time of extraction first, unshielded device between hand and syringe needle second, the medicinal liquid of syringe needle still can make the doctor be subjected to radiation.As everyone knows, radiation is divided into two kinds of external exposure and internal radiations to the irradiating human body mode.External exposure is that radiation source discharges particle at human external, photon acts on irradiating human body.And the protection of external exposure can be adopted three basic means usually, i.e. a kind of in three kinds of means or theirs is comprehensive: shorten the irradiated time as far as possible; Increase distance with radioactive source as far as possible; Between people and radiation source, screen is set.The inventor is at the deficiencies in the prior art for this reason, specialized designs have a shielding cap be convenient to the fixed fixed protection sleeve of needle tube of needle tubing.

Summary of the invention

The purpose of this utility model is, provides a kind of and can effectively overcome above-mentioned defective, both has been convenient to extract medicinal liquid, can reduce the needle tube protecting sleeve of doctor's amount of radiation again.

For achieving the above object, this utility model adopts following technical scheme: a kind of fixed protection sleeve of needle tube, mainly form by body, offer hagioscope on the body, the upper end of body is provided with a shielding cap, it is characterized in that: the junction of shielding cap and body offers the female thread that the needle tubing external diameter coincide.

Owing to adopt such scheme, be not difficult to draw as drawing a conclusion: this utility model is rational in infrastructure, be skillfully constructed, this shielding cap is as the screen of doctor between the syringe needle medicinal liquid, and reduced doctor's amount of radiation, the junction of shielding cap and body offers the female thread that the needle tubing external diameter coincide, increased directly frictional force of needle tubing and protective jacket effectively, played fixedly needle tubing ground effect, thereby shortened the operating time, reach shortening the irradiated time as far as possible and the condition of screen being set of external irradiation protection between people and radiation source, embodied the spirit that people-oriented, had promotional value.

Description of drawings

Below in conjunction with drawings and Examples this utility model is described in further detail.

Accompanying drawing is a structural representation of the present utility model.

The specific embodiment

Referring to accompanying drawing, a kind of protecting jacket of medical-isotope needle tube mainly is made up of body 10, offers hagioscope 20 on the body, and the upper end of body 10 is provided with a shielding cap 30.The junction of shielding cap and body offers the female thread 40 that the needle tubing external diameter coincide.Because the effect of covering of this screw thread, make needle tubing be fixed and shortened the doctor and extracted the time of medicinal liquid, and reduced doctor's amount of radiation, reached shortening the irradiated time as far as possible and the condition of screen being set of external irradiation protection between people and radiation source.

Claims (1)

1, a kind of fixed protection sleeve of needle tube mainly is made up of body, offers hagioscope on the body, and the upper end of body is provided with a shielding cap, it is characterized in that: the junction of shielding cap and body offers the female thread that the needle tubing external diameter coincide.
