Abstract
The purpose of this utility model is to propose the punch that a kind of sponge strip for negative pressure drainage item is perforated.The utility model is that the punch of the sponge strip perforation of negative pressure drainage item is made of guide rail, sliding block and perforation platform；The guide rail is fixed on the side of perforation platform, and the sliding block is movably installed on guide rail, and the perforation platform is equipped with the locating slot parallel with guide rail direction and for sponge strip to be clamped in the fixture in locating slot；The guide pin towards locating slot is also equipped on the sliding block.The operation principle of above-mentioned punch is as follows：The sponge strip of well cutting is positioned in locating slot by first choice, is then fixed sponge strip using fixture, then sliding block is made to be moved to drilling platform direction, and guide pin is made to pass completely through sponge strip, finally exits back guide pin, unclamps fixture, completes drilling.The punch of the utility model can easily fix sponge strip, so as to improve the precision and efficiency of sponge strip perforation, meet the needs of currently producing.
Description
Technical field
The utility model belongs to manufacture technology field of medical appliance, and in particular to a kind of sponge strip for negative pressure drainage item
The punch of perforation.
Background technology
Negative-pressure sealed drainage art（Vacuum Sealing Drainage, VSD）, refer to be cured by the WFleischman of Germany
Teacher is original in early 1990s and is used for the technology of the soft tissue surface of a wound, which wraps up more side openings conductions using medical foam
Merging is by drainage area after pipe, then pastes film closing with permeability and be allowed to be isolated from the outside world by drainage area, connects high negative pressure source, is formed
One efficient drainage system.Negative pressure drainage art needs to protect carrier of the traumatic material as drainage.Medical rank polyvinyl alcohol, which has, to be closed
The features such as into convenience, safety and low toxicity, product quality easily controllable, cheap, easy to use.Medical grade polyvinyl alcohol material passes through
Processing is crossed, the products such as film, sponge are made, medical film and shield traumatic material can be used as to use.
The polyvinyl alcohol foam sponge of negative pressure drainage requires have good bio-compatible performance, good mechanical performance and
Machinability and good therapeutic effect.The biocompatibility of sponge is good, soft texture, small for the irritation of the surface of a wound,
Foreign body sensation unobvious；The elasticity of sponge is good, has porous structure, and aperture is big, and when negative pressure drainage will not be flattened by negative pressure, cause to draw
Stream is not smooth, can save a large amount of time to subsequent cutting and poling process, be conducive to improve productivity, reduce contaminated
Risk；Stretch-proof, anti-extrusion, water absorbing capacity are strong, can meet the requirement used.Therefore, medical PVA sponge is in negative pressure
Drainage block technique is applied will be increasingly wider.
In addition, in actual production, the sponge strip piercing process of negative pressure drainage item is crucial production process, due to sponge strip
Soft texture, conventional punch machine perforate when easily wear it is askew, wear out sponge, high rejection rate, and existing punch can only pass through
Manual operation, time-consuming and laborious and production efficiency is low, can not meet current production requirement.
Invention content
The purpose of this utility model is to propose the punch that a kind of sponge strip for negative pressure drainage item is perforated.
The utility model is the punch of the sponge strip perforation of negative pressure drainage item by guide rail, sliding block and perforation platform structure
Into；The guide rail is fixed on the side of perforation platform, and the sliding block is movably installed on guide rail, the perforation platform be equipped with
The parallel locating slot of guide rail direction and for sponge strip to be clamped in the fixture in locating slot；Direction is also equipped on the sliding block
The guide pin of locating slot.
The operation principle of above-mentioned punch is as follows：
The sponge strip of well cutting is positioned in locating slot by first choice, is then fixed sponge strip using fixture, then make sliding block
It is moved to drilling platform direction, guide pin is made to pass completely through sponge strip, finally exit back guide pin, unclamp fixture, complete drilling.
The installation process of drainage tube and sponge strip is as follows：A guide pin is taken to fix drainage tube, is then drilled out from sponge strip
Hole drainage tube is gone through, the side wall with conduction hole side point of drainage tube is made to be located in sponge strip, guide pin of decorporating is completed to wear
Pipe.
Further, to improve the degree of automation, the sliding block is equipped with slider-actuated mechanism, to drive sliding block along guide rail
It is mobile.The slider-actuated mechanism may be used stepper motor and is made of the stepper motor driven idler wheel.
Further, the fixture is platy structure, and the side of fixture is articulated on perforation platform, and opposite side is equipped with handle
Hand.Hand-held handle, rotates down fixture, you can sponge strip is fixed in locating slot using fixture, operation is very easy.
The punch of the utility model can easily fix sponge strip, so as to improve the precision of sponge strip perforation
And efficiency, meet the needs of currently producing.
