The fixture has the advantages of simple structure, improvement of working efficiency, reasonable design, blockage prevention and so on.
Description
Technical field
The invention belongs to technical field of medical treatment mechanical, relate to the anchor clamps of a kind of anchor clamps, particularly a kind of medical needle blade.
Background technology
In medical device industry, medical needle applications is very extensive, as remaining needle, intravenous needle etc.The intravenous needle that uses on transfusion device at present is made up of needle tubing, blade etc.In the time of assembling needle tubing and blade, earlier blade is put well, then needle tubing is loaded onto, and allowed medical personnel puncture for convenience, when making the needle tubing of medical needle, must allow most advanced and sophisticated cutting edge and stand blade keep specific angle.
The apparatus for assembling of the medical needle that occurs on market is to be arranged in the anchor clamps by the cutting edge with needle tubing, then at the cover blade.Still there is the shortcoming that blade is enclosed within the artificial alignment of needs on the needle tubing in this apparatus for assembling.Therefore, need be with the anchor clamps of the location of blade, and do not have this anchor clamps on the market.
In addition,, again needle tubing is blown, keep not having oil-feed in the needle tubing, detect needle tubing simultaneously and whether stop up because the difference of packaging technology particularly assembling in the technology of medical needle automatically, need be placed on needle tubing in the oil and carry out.And general anchor clamps do not possess this anchor clamps that are applicable to the clamping blade are arranged.
Summary of the invention
The objective of the invention is to have above-mentioned shortcoming at the anchor clamps of existing medical needle blade, provide a kind of simple in structure, can detect the anchor clamps that needle tubing stopped up and prevented the medical needle blade of needle tubing oil-feed.
Purpose of the present invention can realize by following technical proposal: a kind of anchor clamps of medical needle blade, it is characterized in that, the body that comprises bar shaped, described body is provided with the jack of several medical needle blades along the direction of bar shaped, the inner orifice below of each jack is provided with the air inlet cavity, the bottom surface of this air inlet cavity is recessed curved surface, is provided with the inlet channel that above-mentioned air inlet cavity is connected in body.
The anchor clamps bar shaped body of this medical needle blade is cuboid, by about two fastenings form.Jack is arranged on the body, and the shape of each jack and blade adapts.After being inserted into blade in the jack, because the inner orifice of jack below has the air inlet cavity, medical needle blade is held in the bottom surface of air inlet cavity, keeps the upright of medical needle blade so that needle tubing is installed.The bottom surface is the situation that the air inlet area after recessed curved surface can prevent medical needle blade and the bottom surface contacts reduces even directly blocks.Inlet channel is connected to gas circuit, by inlet channel the air inlet cavity is blown, and enters from needle tubing from blade and goes out.
In the anchor clamps of above-mentioned medical needle blade, described curved surface is in the shape of the letter V.Curved surface is in the shape of the letter V, simple in structure, easy making process, and also contact area is little, and air inflow is big.
As the another kind of scheme of curved surface, in the anchor clamps of above-mentioned medical needle blade, described curved surface is curved.
In the anchor clamps of above-mentioned medical needle blade, described inlet channel is the straight trough through above-mentioned air inlet cavity.By straight trough the air inlet cavity is communicated with, in process, can together processes, process easy with curved surface.
As the another kind of scheme of inlet channel, in the anchor clamps of above-mentioned medical needle blade, described inlet channel comprises main channel and several subchannels that are connected with the main channel, described each subchannel and above-mentioned corresponding being connected of air inlet cavity.
In the anchor clamps of above-mentioned medical needle blade, the air inlet of described inlet channel is arranged on the bottom surface of body.
In the anchor clamps of above-mentioned medical needle blade, the air inlet of described inlet channel is arranged on the side of body.
All there is its advantage separately bottom surface and side that air inlet is opened in body, can select according to the actual needs.
Compared with prior art, the below that the air inlet cavity of the anchor clamps of this medical needle blade is in jack can make gas entering from top to bottom, the bottom surface of inlet chamber is recessed curved surface can prevent blade and the obstruction of this bottom surface, increase the area of air inlet, by the air blowing of these structures realizations, simple in structure, reasonable in design to needle tubing.
