Abstract
The utility model discloses an automatic closed blood taking device, which mainly comprises a blood taking syringe needle [1] and a collected syringe needle [3] which is communicated with the blood taking syringe needle [1] through a flexible pipe [2], wherein the collected syringe needle [3] is fixed on a piston [4]. The utility model is characterized in that an air chamber [5] is arranged on the piston [4], a floating ball [6] is arranged in the piston [4], and the air chamber [5] is communicated with an exhaust pipe [7]. The utility model has the advantages that when blood taking and sampling reach a certain setting quantity, the automatic closed blood taking device can be automatically closed, and blood samples are stopped collecting. The automatic closed blood taking device is safe and reliable to use, which is simple and convenient.
Description
Technical field
This utility model belongs to the blood collection device that uses in a kind of medical inspection, and definite saying is a kind of automatic sealing blood-taking device.
Background technology
For medical treatment and other professional blood biochemical check tests, need sample of blood, drawn, generally be to adopt the mode of syringe pump to come sample of blood, drawn, because the reciprocating motion of the plunger of syringe sometimes causes blood constituent destroyed, What is more, and the generation maloperation makes air be injected into by in picker's body, causes very abominable accident and influence.In order to address this problem, the device that once adopted vacuum to gather, but because the restriction of equipment, after the storage of long period, vacuum descends or disappears, can't the vacuum sample of blood, drawn and cause.Designer of the present utility model has done research in earnest, has proposed goal of the invention of the present utility model.
Summary of the invention
Goal of the invention of the present utility model is in order to overcome defective and not enough the putting forward that exists in the present blood sample collection.A kind of automatic sealing blood-taking device promptly is provided.
Technical solution of the present utility model is to realize like this, should seal blood-taking device automatically, mainly has a blood collection needles [1], the collection syringe needle [3] that is communicated with blood collection needles [1] by flexible pipe [2], collecting syringe needle [3] is fixed on the plug [4], it is characterized in that having an air chamber [5] on the plug [4], have a ball float [6] in it, this air chamber [6] is communicated with by exhaustor [7].
Beneficial technical effects of the present utility model is: when blood drawing, when sampling the setting quantity that reaches certain, this device can seal automatically, stops sample of blood, drawn, and is safe and reliable, simple and convenient.The vacuum that the vacuum harvester neither can occur disappears and can't gather, and also can not take place because the problem of the excessive collection that misoperation causes.Its advantage is conspicuous.
Description of drawings
Accompanying drawing 1 is a structural profile schematic views of the present utility model, and accompanying drawing 2 is A enlarged drawings of accompanying drawing 1.Sequence number in the accompanying drawings is described as: 1, blood collection needles, 2, flexible pipe, 3, collect syringe needle, 4, plug, 5, air chamber, 6, ball float, 7, exhaustor, 8, test tube.
The specific embodiment
Below in conjunction with the embodiment that provides in the accompanying drawing, structure of the present utility model and use are elaborated.With reference to accompanying drawing, this device mainly has a blood collection needles [1], the collection syringe needle [3] that is communicated with blood collection needles [1] by flexible pipe [2], collecting syringe needle [3] is fixed on the plug [4], it is characterized in that having an air chamber [5] on the plug [4], have a ball float [6] in it, this air chamber [6] is communicated with by exhaustor [7].Ball float and air chamber are as shown in Figure 2, the ball float design has certain quality, when normal collection blood under the effect of human vein pressure during aerofluxus, ball float is because the gravity of self, the right moves near the position of exhaustor to dotted line in accompanying drawing 2, the air in the system can not all block exhaustor, so can successfully be discharged; Continue to increase and expired test tube when the blood storage of gathering, then under the buoyancy of blood, ball float floats, and the position of the double dot dash line to the accompanying drawing 2 with the exhaustor sealing, stops to gather, and test tube is properly preserved get final product.
