Description

A kind of intravenous needle fin feed mechanism

Technical field

This utility model is related to the technical field of intravenous needle fin assembly equipment in the middle of medical apparatus and instruments, more particularly to a kind of quiet Arteries and veins pin fin feed mechanism.

Background technology

With the raising of social life level, transfusion is more widely used in clinical disease as a kind of important treatment modality In example.Transfusion is to be input into internal heavy dose (single administration is in more than 100ml) injection, infusion process by intravenous drip In by transfusion device adjustment injection drop speed, continue and stably enter vein, with supplement body fluid, electrolyte or provide nutrient Matter.

In medical transfusion industry, disposable transfusion device has obtained wide due to easy to use and safety and sanitation advantages General application.Need not carry out disinfection during transfusion, user only needs to take apart pack and transfusion device and intravenous needle link together i.e. Can.But, unclean transfusion device weakens not only can the drug effect of medicine, more likely cause cross infection, greatly compromise disease The health of people.It can be seen that, it is ensured that the clean tool of transfusion device has very important significance.

Intravenous needle（Also known as modeling pin）It is the important component part of transfusion device, for piercing through patient's vein, and medicinal liquid is imported Intravenouss.Existing intravenous needle includes needle stand, draw point and single blade.For example, Chinese patent【The patent No. ZL200820018844.9；Authorization Notice No. CN201164629Y】A kind of disclosed intravenous needle, with needle body, needle body front end is Pinpoint inclined plane, needle rear end side arrange needle handle, pinpoint inclined plane direction upward when needle handle be located at needle rear end left side.

In prior art, the needle handle of intravenous needle can also adopt dual vane type, for example, Chinese patent【The patent No. ZL200520086804.4；Authorization Notice No. CN2829755Y】Disclosed single use safety intravenous needle, including needle stand, Needle point, blade and needle guard, the blade is located at needle stand both sides.

In order to ensure not to be contaminated, medical apparatus and instruments（This utility model is referred in particular to for assembling or assembling intravenous needle Tab arrangement or equipment）Assembling try not manual participation, manual disadvantage is the upper pathogenic bacteria of easily attachment, Cause product hygienic requirements unqualified；Simultaneously manual assembling speed is relatively low.Medical apparatus and instruments kludge is employed automatically Change control mode carry out automatic assembling, will not polluted product, the sanitary index of product can be made to meet national standard, with higher Practical value.

Medical apparatus and instruments are generally made up of multiple parts, and some parts are to need to be installed according to a certain direction , it is impossible to there is deviation, to ensure that the medical apparatus and instruments being completed meet the requirements.However, be used for by parts carry out feed and The mechanism of transmission usually not arranges the adjusted device of parts, even if some are provided with adjusted device there is also individual parts Towards incorrect phenomenon.If carrying out assembling according to this direction and will result in the requirement that product does not reach setting, product is caused Scrap.

For example, Chinese patent【Patent No. ZL200720113479.5, Authorization Notice No. CN201076644Y】Disclose one The kludge of plastic needle component for medical purpose is planted, it is solved existing modeling pin and is all assembled using manual mode, this assembling Mode inefficiency, easily makes the contaminated problem of plastic needle component.Including one and the joining rotating shaft of motor shaft, in rotating shaft Fixed one rotating disk that can be rotated with rotating shaft, is evenly distributed with several for fixing the folder of workpiece on rotating disk Tool, is provided with three kinds of feed appliances around described rotating disk, that is, mould pin feed appliance, filter cap feed appliance and sheath feed appliance.

Obviously, the device is also not disclosed the structure with regard to adjusting parts installation direction.Modeling pin of the prior art is usual The rail bar transmission being be arranged in parallel using two, although two catch in the middle part of modeling pin are able to ensure that modeling pin is vertically transmitted, but It is that the side pipe for moulding pin is difficult to position, there is side pipe towards transmission direction or dorsad transmission direction two ways, is easily caused a row Modeling pin（That is intravenous needle fin）In exist towards contrary situation.

Other Chinese patent【Patent No. ZL200710070560.4, substantive publication number CN101152586A】Disclose one kind " packaging technology and its kludge of plastic needle component for medical purpose ", modeling pin, filter cap, sheath are individually positioned in respective feed appliance by it Interior, each feed appliance will be put in after accessory permutation therein each delivery track being arranged in an orderly manner around rotating disk arrangement On, by filter paper volume be arranged on when filter disc is punched get off when fairly fall on filter cap delivery track filter cap in filter disc punching On cutting apparatus.Although noise when it operates smoothness, smooth running, works is low, high degree of automation.But, mould the aerofluxuss of pin Mouth position cannot be unified, and cause to need in addition to be corrected it in assembling process, and its packaging efficiency is relatively low.Existing other modelings Pin（Or intravenous needle）Assembling also all there is a problem that similar.
