Description

Remaining needle sleeve head forming machine

Technical field

The utility model belongs to the processing equipment technical field of medical equipment, is specifically related to a kind of remaining needle sleeve head forming machine.

Background technology

Remaining needle is accustomed to being referred to as trochar again; owing to remaining needle both had flexibility good, long be difficult for wearing out vascular wall at the intravenous indwelling time, help reducing the strong point of the painful and protection blood vessel that the patient causes because of repeated localised puncture; have again and be convenient to clinical application, promptly rescue and reduce the particularly characteristics of nursing staff's workload of medical worker, therefore clinical practice in recent years is very extensive.

As shown in the above description, so-called remaining needle is by syringe needle or claims needle body that sleeve pipe is sent into vein, remove syringe needle after, sleeve pipe just is retained in intravenous.The processing request of remaining needle sleeve pipe is very harsh, need to the head of sleeve pipe implement chamfered form good tapered, to avoid burr occurring at head.Because, if there is burr in the head of sleeve pipe, enter in patient's body so after, burr easily causes and the vascular wall friction, causes inflammation of vein etc.Usually adopt isolated plant to the moulding of sleeve pipe head for this reason, the structure of the remaining needle sleeve head forming machine in the prior art is by shown in Figure 5, comprise base 1, be located at the anchor clamps driving mechanism 2 on the base 1, be located at the anchor clamps sliding seat 3 on the anchor clamps driving mechanism 2, be located at the plug anchor clamps 4 on the anchor clamps sliding seat 3, be located at the plug 5 on the plug anchor clamps 4 and be arranged on corresponding by die holder 61 on the support 1 with described plug 5, the tapering builder 6 that mould 62 and heating head 63 constitute, in the time will promptly being processed into taper to the moulding of sleeve pipe head, as long as sleeve pipe is nested with on the plug 5, because plug 5 is to be fixed on the plug anchor clamps 4, be fixed on the anchor clamps sliding seat 3 owing to plug anchor clamps 4 again, also fit on the anchor clamps driving mechanism 2 owing to anchor clamps sliding seat 3 is movably sliding, therefore, gas circuit conduit 21 air inlets when anchor clamps driving mechanism 2, promote mobile cylinder 22 and take anchor clamps sliding seat 3 by mobile cylinder 22 and move to the direction of aforesaid tapering builder 6, make the remaining needle sleeve pipe (illustrating by dotted line among the figure) that is nested with on plug 5 enter mould 62, because mould 62 is by heating head 63 heating, therefore the head by 62 pairs of remaining needle sleeve pipes of the mould under the heated condition is shaped to taper.

The remaining needle sleeve head forming machine of said structure is difficult to ensure Forming Quality and desirable qualification rate to the remaining needle sleeve head moulding time, because being difficult to will to be retained in by the die cavity that is in the mould 62 under hot the burr of head in remaining needle sleeve pipe process after entering mould 62, fully removes remaining needle sleeve head, even removed burr, the tapering effect of its head is also relatively poor, can't be in clinical practice.In order to guarantee clinical result of use, production firm can only maintain strict control over the check pass, under magnifying glass to one of the remaining needle sleeve pipe after the moulding do not dredge, one piece do not carry out desk checking, therefore many, the inefficiency of reviewer that not only drops into, and reviewer's labour intensity is big with leaking.Because qualification rate is low, only be about 50-60% on the other hand, therefore cause serious waste phenomenon, not only cause resources loss, and cause production cost to improve.

In view of this, very be necessary the structure of aforesaid remaining needle sleeve head forming machine is improved, technical scheme described below produces under this background.
