Abstract
A dedicated needle provided with a needle cap and used for collecting blood-gas analysis specimens relates to a collecting needle. The dedicated needle for collecting blood-gas analysis specimens is provided with a needle cap which has length longer than that of the dedicated needle by 1 plus or minus 0.2 cm, and is easily inserted and capable of being sealed. When the utility model is used, the needle cap is put into a treatment disk for the standby application before the blood-gas analysis specimens are extracted; and after the arterial blood gas analysis specimens are extracted, the syringe needle should be immediately stuck into the needle cap and sent to a laboratory for the testing. The needle cap of the utility model is easily inserted and capable of being sealed, so that the sticking of the needle tip is facilitated, and the operation can be conducted smoothly; the needle cap has the length longer than that of the dedicated needle by 1 plus or minus 0.2 cm, the sticking to the finger of an operator is hard to happen, and the penetration to allow the entrance of the air is also very difficult; after the blood-gas analysis specimens are collected, the dedicated needle can be immediately isolates from the air, so that the accuracy of the results is ensured, and reliable blood-gas analysis data are correctly and immediately provided for a clinician to ensure the immediate and reasonable treatment of a patient. The dedicated needle is favorable for the clinical widespread application.
Description
Technical field
This utility model relates to a kind of collection syringe needle.
Background technology
Arterial blood gas analysis, because of its result rapidly, accurately, the respiratory function of body and acid-base balance state had describe accurately and be widely used in clinical.Particularly particularly important when critical illness rescues, become one of detection index of clinical necessity.But, obtain blood gas analysis data accurately, except the instrument of precision, how strict control indexes guarantees the blood gas analysis specimen when collect specimen, after collection, can cut off with air immediately, be a very important link.At present after a lot of hospitals extract the blood gas analysis specimen, syringe needle is thrust in the rubber closure of storage blood test tube, because rubber closure can be little for the area of puncture, be difficult for puncture, cause needle point flexible and easily stab phenomenon such as operator's finger, the carrying out smoothly of influence operation makes the blood gas analysis specimen can not be isolated with air immediately, have a strong impact on result's accuracy, thereby also influenced patient's diagnosis and treatment effect.
Therefore, it is isolated with air immediately to design a kind of syringe needle that can make after gathering the blood gas analysis specimen, and easy to operately seems particularly important.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aims to provide a kind ofly can after gathering the blood gas analysis specimen, make syringe needle isolated with air immediately, and safety and sanitation, the easy to operate special-purpose syringe needle of the blood gas analysis collection of specimens that needle cap is arranged.
The implementation of this utility model purpose is, the special-purpose syringe needle of blood gas analysis collection of specimens of needle cap is arranged, and blood gas analysis collection of specimens special needle headband has a needle cap of easily inserting, can seal than special needle head length 1 ± 0.2cm.
When using this utility model, before the extraction blood gas analysis specimen, it is standby that needle cap is put into the treatment dish, after the extraction arterial blood gas analysis standard, immediately syringe needle thrust in the needle cap, send the laboratory chemical examination.
This utility model has following advantage:
1, needle cap is easily inserted, can be sealed, and thrusts so be easy to needle point, and operation can be carried out smoothly;
2, needle cap is than special needle head length 1 ± 0.2cm, and operator's finger is not vulnerable to stab, and also is difficult for penetrating and advances air;
3, the blood gas analysis specimen can be cut off with air after gathering immediately, has guaranteed result's accuracy, reliable blood gas analysis data accurately and timely is provided for the clinician, makes the patient obtain reasonably diagnosis and treatment in time;
4, needle cap before the extraction, is put into the treatment dish with first sterilization of special needle, encapsulation, and after the extraction, syringe needle thrusts immediately, safety and sanitation.
This utility model is worth clinical and is extensive use of.
Description of drawings
Accompanying drawing is this utility model structural front view.
The specific embodiment
With reference to accompanying drawing, the special-purpose syringe needle 1 of blood gas analysis collection of specimens has a needle cap 2 of easily inserting, can seal than special needle head length 1 ± 0.2cm.
Square or the cylinder of needle cap 2 for making with the material of plasticine class conveniently thrusts.Because of disposable 5ml syringe needle head length is 3cm, so the length of side of square is 4 ± 0.5cm, cylindrical height is 4 ± 0.2cm.The length of needle cap is longer than the length of syringe needle, thus when operation easy damaged operator's finger not, also be difficult for penetrating and advance air.
Be made into square or cylinder with plasticine, cork or soft rubber, the length of side of square should be 4 centimeters, and cylindrical height should be 4 centimeters.Because of disposable 5ml syringe needle head length is 3 centimeters, the length of being longer than syringe needle because of the length of needle cap is so easy damaged operator's finger not during operation also is difficult for penetrating and advances air.
When using this utility model, before the extraction blood gas analysis specimen, it is standby that needle cap is put into the treatment dish, after the extraction arterial blood gas analysis specimen, immediately syringe needle thrust in the needle cap, send the laboratory chemical examination.
This utility model needle cap is easily inserted, can be sealed, and thrusts so be easy to needle point, and operation can be carried out smoothly; Needle cap is than special needle head length 1 ± 0.2cm, and operator's finger is not vulnerable to stab, and also is difficult for penetrating and advances air; The blood gas analysis specimen can be cut off with air after gathering immediately, has guaranteed result's accuracy, reliable blood gas analysis data accurately and timely is provided for the clinician, makes the patient obtain reasonably diagnosis and treatment in time.This utility model is worth clinical and is extensive use of.
