Description
Technical field
The present invention relates to a kind of safety type venous detaining needle.
Background technology
In recent years, the relevant expert points out that the degree of danger that medical worker's occupation is infected depends on the prevalence rate of blood sexually transmitted disease (STD) among the crowd.China is one of hepatitis B state occurred frequently, and the carrier of hepatitis B virus has 1.2 hundred million approximately, and the infection rate of hepatitis C also reaches 1.7%, and the popular of AIDS also got into the quick rise period in China, and therefore, it is dangerous that the medical worker of China is being faced with serious occupational exposure.
Modern medicine proves, cross infection takes place when avoiding to human input media, and venous detaining needle must disposable use, is using later promptly as garbage disposal.Use maximum disposable use venous detaining needles to form at present by flexible pipe, thimble assembly, needle tubing assembly, calparine cap; The existing greatest problem of this remaining needle is after the needle tubing assembly uses; Its syringe needle still is trapped in the outside, with respect to the sharp-pointed degree of syringe needle, be not merely remaining needle rubbish carrying, destroy and make troubles; Because of the thing of stabbing the medical and nursing work personnel accidentally often takes place, this secondary cross infection of pathogenic bacteria just inevitably can occur simultaneously.Practice shows, the damage that the needle stick injuries that dangerous needle set causes obviously causes more than other accidents.Improving the safety of venous detaining needle, has been the problem of paying close attention in the industry.
At present, mostly the design of safety indwelling needle is manual operation rollback needle point to needle tubing on the market, and this design causes needle stick injuries if careless or artificial malice still can be released needle point once more, perhaps reuses, and causes bad harm.
Chinese patent document CN1245077A discloses a kind of multipurpose high-safety needle staying on vein for automatic infusion; Be on the pedestal 31 of draw point 3, to be provided with a pull bar 311, the handle 311a of tie rod end exposes, simultaneously; Pedestal 31 is provided with bayonet socket 312, and sleeve 33 is provided with bayonet socket 332.After puncturing successfully,, make draw point 3 get into sleeve 33 with pedestal 31 through pulling handle 311a; When pedestal 31 arrives sleeves 33 terminal points, bayonet socket 312 engages with bayonet socket 332, at this moment from the root pull bar 311 that sleeve 33 exposes that fractures; Draw point 3 and pedestal 31 are trapped in the sleeve 33, prevent to stab personnel.Though the remaining needle of this structure can engage with bayonet socket 332 through bayonet socket 312 draw point 3 is hidden in the sleeve 33; Its structure more complicated; Must be in the operation from the root pull bar 311 that sleeve 33 exposes that fractures, very inconvenient, also comprise the pull bar 311 of a root fracture in the abandon of cleaning.
Chinese patent document CN1277874A discloses a kind of multipurpose high-safety needle staying on vein for automatic infusion, is button arm 313 is set in draw point portion 31, on protective sleeve, is provided with button hole 325, and spring 328 is compressed in draw point portion 31 front ends.After puncturing successfully, through Pressing fastener arm 313, its hook part 313a and button hole 325 are triped, under the effect of spring 328, draw point portion 31 is by in the accommodation aperture 323 and 326 about the bullet people.Though it is more convenient that this mode is operated,, if do not note slightly in the operation, touch button arm 313 in case push, just might cause about 31 retractions of draw point portion making remaining needle generation misoperation in the accommodation aperture 323 and 326.
Summary of the invention
The objective of the invention is to: the present situation in using to present remaining needle, and existing puncture needle tubing hides the complex structure that protective measure exists, or inconvenient operation, or be prone to cause problem such as maloperation, a kind of new safety type venous detaining needle is provided.
The objective of the invention is to realize like this: a kind of safety type venous detaining needle; Comprise needle tubing sheath, conduit tube component, needle tubing assembly; Wherein, Described conduit tube component comprise inlying catheter, " Y " shape catheter block, metal wedge, batching pig, Great Wall Software's pipe, flexible pipe seat, calparine cap and and the slip clamping plate, described needle tubing assembly comprises puncture needle tubing, needle stand body and cylindrical shell, cylindrical shell is provided with handle; It is characterized in that:
Described needle stand body contains anterior needle stand and rear portion base; They are concentric cylindrical; The diameter of rear portion base is greater than the diameter of anterior needle stand, and the circumferential surface of rear portion base is protruding stupefied to outer lug of two of uniform distribution at least, presents groove between the two protruding stupefied adjacent edges; Each protruding stupefied lower end is provided with a positioning tooth, also is provided with the cage knob of a convexity on one of them protruding stupefied protruding top; Described groove is uniformly distributed in the circumferential surface of rear portion base;
Said barrel front end is provided with spring base, the cylindrical shell front inner wall be provided with the needle stand body in the corresponding convex of each protruding stupefied lower end positioning tooth location stupefied, the stupefied width in described convex location is less than or equal to the recess width of said needle stand body rear portion base circumferential surface; Also be provided with the cage knob locating slot and the cage knob sliding tray that penetrate cylindrical shell on the cylindrical shell; Described cage knob locating slot and cage knob sliding tray are the parallel slot that axially is provided with; Their front end is communicated with each other through the transition breach; Wherein, the cage knob sliding tray extends to barrel tip, and cage knob sliding tray end is provided with the covering storehouse of blocking cage knob; Cage knob is arranged in said parallel slot, and its top exposes to cylindrical shell, and can be hidden in the described covering storehouse; Barrel tip is provided with end plug;
The puncture needle tubing is installed on the anterior needle stand central authorities of needle stand body front end, and the cylinder of said anterior needle stand can pass the spring base of barrel front end;
Spring housing is contained on the cylinder of said anterior needle stand, and an end of spring is positioned at spring base, and the other end is butted on said rear portion base; Or said cage knob is arranged in the cage knob locating slot, and it is stupefied corresponding that the tooth root of said each protruding stupefied lower end positioning tooth and the forward convex of cylindrical shell are located, and spring is compressed, and the needle stand body is limited in barrel front end; Or said cage knob is arranged in the cage knob sliding tray, the forward convex of cylindrical shell location stupefied with institute rear portion base in groove corresponding, spring freely extends, and shifts the needle stand body onto the cylindrical shell rear portion, cage knob is hidden in the covering storehouse.
In the present invention: 3～8 of the circumferential surface uniform distribution of rear portion base are protruding stupefied to outer lug; The length of cage knob sliding tray is equal to or greater than the physical length that needle stand body front portion passes cylindrical shell exposed parts and the addition of puncture needle tubing; The length of cage knob locating slot is equal to or greater than the length of cage knob front end to the rear end.
