Description
Technical Field
The utility model relates to the technical field of medical auxiliary equipment, concretely relates to prevent stabbing easy confined blood gas needle.
Background
The blood gas needle is used for collecting human blood and detecting, and in the blood collection process, after a nurse collects blood to a patient by using blood gas, a needle head is usually pricked into a rubber plug, and then the needle head is taken down and a seat cap is screwed on to completely seal the needle tube. In the process, the rubber plug for fixing the needle point is easy to fall off, so that medical staff are stabbed by the needle head, and certain pathogenic bacteria possibly exist in the needle head due to the fact that blood of a patient is contained in the needle head, so that the medical staff are exposed occupationally and infected with the pathogenic bacteria, and the life safety of the medical staff can be threatened.
Meanwhile, the process of taking down the needle head before blood is sent for inspection after blood collection and then using the conical head cover to seal the injector is complex to operate and cannot be finished at one time, so that the contact between air and blood can be caused.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve above-mentioned problem, designed one kind and prevented stabbing easy confined blood gas needle, conveniently closed the needle point and hide after the blood sampling, prevented to stab medical personnel, avoided causing the infection to can avoid blood and the air contact in the syringe.
The utility model discloses an overcome the not enough of prior art, the technical scheme of adoption is: a puncture-proof blood-gas needle easy to close is mainly composed of a needle point, a needle cylinder, an end cover and a push rod, wherein groove slideways are arranged outside the needle cylinder and the end cover, the needle cylinder and the end cover are connected with a sleeve through the groove slideways, a sealing plug is embedded at one end of the sleeve close to the needle point, a limiting mechanism used for fixing the sleeve is arranged at the other end of the sleeve, and the needle point penetrates through the sealing plug;
the groove slides are separable at the junction of the barrel and the end cap.
The groove slideway is made of PVC or PP materials.
Stop gear is by calorie post and recess slide interact fixed position, and the pointer on card post upper portion connects the stem perpendicularly, the stem bottom is soft rubber layer, soft rubber layer and recess slide interference match.
The length of the groove slideway is the same as the distance from the sealing plug to the wrapping needle.
The syringe and the sleeve are both made of transparent materials.
The technical effect who produces is owing to adopted above-mentioned technical scheme, the beneficial effects of the utility model are that:
1. when blood is drawn for the patient, the clamping column is screwed down to be perpendicular to the needle cylinder, so that the core column is matched with the groove slideway, and the sleeve cannot move back and forth under the limitation of the clamping column. The needle tip is inserted into the artery of the patient to withdraw the patient's blood.
2. After the bloodletting finishes, the post will block is screwed on, stem and recess slide phase separation this moment, the sleeve loses the restriction of blocking the post, move the sleeve forward along the recess slide on the cylinder, it can wrap up the needle point to send telescopic front end, the card post just moves to in the recess of screw end cover department this moment, then it is perpendicular with the cylinder to spin down card post pointer, recess looks adaptation in stem and the end cover, can unscrew the syringe needle simultaneously when rotating the sleeve, convenient operation, avoid medical staff at the blood sampling, the blood of chemical examination or take place the acupuncture when destroying the hemostix and hinder, guarantee medical personnel's life safety, prevent that the occupation from exposing.
3. The syringe and the cylinder are made of transparent materials. The blood sampling amount of the blood gas needle is convenient to observe.

FIG. 1 is a side view of a blood gas needle of the present invention;
fig. 2 is a schematic structural view of the clamp column in the blood gas needle of the present invention.
In the figure, 1, a needle tip; 2. a sealing plug; 3. a sleeve; 4. a needle cylinder; 5. a push rod; 6. clamping the column; 7. a groove slideway; 8. an end cap; 9. a stem; 10. a rubber layer; 11. a pointer.
Detailed Description
In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand and understand, the present invention is further explained by combining with the specific drawings.
As shown in fig. 1 and 2, the puncture-proof blood-gas needle easy to close comprises a needle point 1, a needle cylinder 4, a push rod 5, a sleeve 3, a sealing plug 2, a clamping column 6, a piston and a core rod which are arranged in the needle cylinder 4, wherein the sealing plug 2 is embedded in one end of the sleeve 3 close to the needle point 1, the sealing plug 2 is made of an elastic material such as silica gel, and the sealing plug 2 is embedded in the sleeve 3. The needle point 1 penetrates through the sealing plug 2, the groove slideways 7 are arranged on the needle cylinder 4 and the end cover 8, the end cover 8 is preferably a threaded end cover, two groove slideways 7 can be symmetrically arranged on the outer wall surface of the needle cylinder, and three to four groove slideways can also be uniformly distributed on the outer wall surface of the needle cylinder at intervals; the sleeve 3 slides relative to the needle cylinder 4 through the groove slideway 7, so that the sealing plug 2 wraps the needle point 1 to form a seal, and the air is prevented from entering the needle point 1. The other end of the sleeve 3 is provided with a limiting mechanism for fixing the sleeve 3. Stop gear is by calorie post 6 and 7 interact fixed positions of recess slide, and stem 9 is connected perpendicularly to pointer 11 on calorie post 6 upper portion, 9 bottom of stem is soft rubber layer 10, soft rubber layer 10 and 7 interference fit of recess slide. The sleeve 3 is restricted from moving back and forth when drawing blood for a patient. The needle tip 1 is inserted into an artery of a patient so that blood of the patient can be extracted.
After the blood drawing is finished, the pointer 11 is rotated, the soft rubber layer 10 leaves the groove slide way 7, the sleeve 3 loses the limitation of the clamping column 6 at the moment, the sleeve 3 is moved along the groove slide way 7 until the front end of the sealing plug 2 can exceed the front end of the needle point 1 and stop, the needle point 1 is sealed by the sealing plug 2 at the moment, the clamping column 6 just moves to the groove slide way 7 on the end cover 8 at the moment, and the clamping column 6 is in interference fit with the groove slide way 7 in the end cover 8.
Subsequently, the needle point 1 and the end cover 8 can be taken down from the needle cylinder 4 by rotating the sleeve 3, and when the needle point 1 is pulled down, the whole needle point 1 is positioned in the sleeve 3, so that a nurse is not easy to be punctured, and the risk of cross infection of the nurse is reduced.
It is to be understood that the disclosed embodiments are merely exemplary of the invention, and are not intended to limit the invention to the precise embodiments disclosed. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without making creative efforts belong to the protection scope of the present invention.
