Abstract
The present invention relates to a safety retention needle. It includes a catheter seat and a safety protection shell. On the safety protection shell a guiding groove is set. It is characterized by that on the outer wall of external end portion of the described catheter seat a projection is set, and on the wall surface of front end of the described safety protection shell a fastening hole is set, and said fastening hole can be matched with said projection. Besides, said invention also provides the concrete structure of said safety protection shell.
Description
Technical field
The present invention relates to a kind of disposable medical apparatus and instruments, relate in particular to the safe type retention needle of uses such as being used for human body artery and vein transfusion (blood), pressure measurement.
Background technology
Remaining needle generally comprises puncture needle and the inlying catheter that is enclosed within on the puncture needle, is to utilize inlying catheter to carry out artery and vein infusion medicinal liquid to the patient.Therefore remaining needle has the vascular puncture of minimizing number of times, reduces intravenous extravasation, and little to blood vessel irritation, helps advantages such as clinical application and urgent rescue.
But existing remaining needle needle tubing assembly is the state that is in outside being exposed to after puncture finishes and extracts, so medical personnel are injured by accidental needle sticks easily in cleaning, destruction when discarding remaining needle needle tubing assembly.
The pollution that causes because of the puncture of the mistake of sharp needles in the medical apparatus and instruments, infect and become social problem.So preventing the means of contingent such as mistake puncture grade is one of content of paying close attention to of industry always.
The applicant number is 03141566.0 in Chinese patent application, and the applying date is to disclose the structure of a kind of denomination of invention for " a kind of safety venous transfusion remaining needle with the wing " in 11 days July in 2003, is characterized in: be provided with a safeguard protection shell.Referring to Fig. 1 (a)～(b); this safeguard protection shell is a tubular shell 1; its length is greater than the length of described puncture needle assembly 2; and be provided with one for puncture needle wings 21 roots localized locked grooves 11 on the shell face of this safeguard protection shell rear end, and one links to each other with this locked groove and extends to the guiding conduit of its end along described safeguard protection shell length direction.Wherein: the front end 13 of described safeguard protection shell can be plugged in the draw-in groove 31 that described catheter block 3 ends and this safeguard protection shell front end 13 be equipped with; The root of described puncture needle wings 21 can move in the guiding conduit 11 of described safeguard protection shell, until entering locked groove 12.
The safeguard protection shell of above-mentioned remaining needle by being provided with makes puncture needle enter the safeguard protection shell when withdrawing from from indwelling casing tube, makes puncture needle obtain shielding, therefore, prevents that fundamentally medical personnel are punctured the generation that acupuncture injures the incident of catching.
Yet, because above-mentioned safeguard protection shell 1 is plugged in the catheter block end draw-in groove 31, this connected mode lacks effective lock function on the one hand, make puncture needle assembly 2 from indwelling casing tube, withdraw from and exist the hidden danger that comes off when entering the safeguard protection shell, and the security performance that influence is used; On the other hand, often have relatively high expectations with the matching degree of the draw-in groove 31 of catheter block in the end 13 of safeguard protection shell, thereby reduced the versatility of safeguard protection shell.
Summary of the invention
The object of the present invention is to provide that a kind of safety in utilization is good, the safe type retention needle of highly versatile.
A kind of safe type retention needle provided by the present invention; comprise catheter block and safeguard protection shell; this safeguard protection shell is provided with the guiding conduit; it is characterized in that: on the outer wall of the outer end of described catheter block, be provided with a projection, and on the wall of the front end of described safeguard protection shell, be provided with the button hole that interlocks and join with this projection.
In above-mentioned safe type retention needle, the oblique shape locating flange that guiding conduit one side of safeguard protection shell rear end is provided with, being positioned at this flange guiding conduit afterwards is locked groove.
In above-mentioned safety venous transfusion remaining needle, on guiding conduit one side of safeguard protection shell rear end, be provided with one with the projection of described guiding conduit dislocation, be provided with a sagging groove at this guiding conduit opposite side.
Adopted above-mentioned technical solution; after puncture needle uses; its tip portion is protected effectively by the safeguard protection shell; realize that safety abandons; and make the safety of using be improved by the projection that increases and the lock function of button hole, improved the versatility of safeguard protection shell simultaneously.

The specific embodiment
As shown in Figure 2; a kind of safe type retention needle provided by the present invention; comprise catheter block 3 ' and safeguard protection shell 1 '; the safeguard protection shell is provided with the guiding conduit; be characterized in: on the outer wall of the outer end of catheter block 3 ', be provided with a projection 32, and on the wall of the front end of described safeguard protection shell, be provided with the button hole 12 that interlocks and join with this projection 32.
The structure of safeguard protection shell can for: shown in Fig. 2 (a), the oblique shape locating flange 14 that guiding conduit 11 ' one side of safeguard protection shell 1 ' rear end is provided with, the guiding conduit that is positioned at after this flange 14 is a locked groove 12 '.
The structure of safeguard protection shell also can for: shown in Fig. 2 (b), at safeguard protection shell 1 " the guiding conduit 11 of rear end " be provided with on the side one with described guiding conduit 11 " projection 14 of dislocation ", be provided with a sagging groove 15 at this guiding conduit opposite side.
Above embodiment is only for the usefulness that the present invention is described, but not limitation of the present invention, person skilled in the relevant technique, under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong within the category of the present invention, should be limited by each claim.
