Abstract
The utility model relates to a medical injury-free injector needle. The needle comprises a needle bed (4) and a tubular needle core (3) which are connected with each other, and is characterized in that an arc bump (2) is arranged at the tail end of the needle core (3); and a liquid outlet (1) is formed at the lateral side of the arc bump (2). The needle is formed by the needle bed and a blunted needle core, so that accidental injury, especially punctured skin, is prevented even in an unarmed or sterile glove wearing state, and the balance pressures of the injector and the connecting pipeline are controlled, so that an operator does need to worry about the fact that skin or finger is punctured in connecting, examining, detaching and other steps, and the connecting pipe is prevented from generating purrs to fulfill the requirement of safe operation of medical staff. The needle can be universally used in urography and other examinations.
Description
Technical field
This utility model relates to a kind of medical not damaged syringe needle.
Background technology
Along with medical skill constantly develops, in conventional diagnosis and treatment activity, especially not only require in the noninvasive test patient is protected to greatest extent, also to carry out self-protection simultaneously to the medical worker.Therefore, adopting equipment such as harmless processing, protection to operate is a kind of important method of medical worker's self-protection.
But the general syringe needle that uses at present is when connecting pipeline; The careless skin puncture of part medical personnel is always arranged, accidentally injure finger; Or even patient's part infectious agent, liquid etc. are carried out iatrogenic infection give the operator, therefore seeking a kind of safe and reliable injection needle becomes pressing for of numerous medical personnel.
The utility model content
Can be even the purpose of this utility model provides a kind of syringe that under free-hand state, uses by the medical not damaged syringe needle of syringe needle accidental injury.
A kind of medical not damaged syringe needle comprises the needle stand and the tubulose nook closing member that are connected, and its special feature is that the end of said nook closing member is provided with an arc convex, has liquid outlet in the side of this arc convex.
Wherein arc convex is round table-like.
The syringe needle of this utility model is made up of needle stand and the nook closing member of justifying blunt processing; Therefore free-hand or can not cause accidental injury wearing under the sterile gloves state; Especially skin is punctured; And the pressure balance in having realized controlling syringe and being connected pipeline; Make the operator in links such as connection, inspection, dismounting, needn't worry to be wounded by stabbing skin, point and avoid connection tube to produce burr phenomena, thereby realized medical personnel's safety operation requirement, the syringe needle of this utility model can be popularized in inspections such as urinary system retrograde urography and use.
Description of drawings
Accompanying drawing 1 is the structural representation of this utility model.
The specific embodiment
As shown in Figure 1, a kind of medical not damaged syringe needle comprises the needle stand that is connected 4 and tubulose nook closing member 3, is provided with an arc convex 2 at the end of nook closing member 3, has liquid outlet 1 in the side of this arc convex 2, and more particularly this arc convex 2 is round table-like.
Because needle stand 4 parts of this utility model syringe needle are identical with existing syringe needle; Therefore the syringe needle of this utility model can be supporting with the syringe of present use; Its method for using and common puncture, the first appearance of pumping needle; The syringe needle of this utility model can be in the inspection of urinary system retrograde urography, a kind of medical apparatus and instruments that uses when being connected with ureteral catheter as syringe.After inspection finishes, after recovery, cleaning, sterilization etc. are handled, can reuse.
