3, detect the air pressure in syringe by pressure monitor module, if the syringe internal gas pressure after blood sampling changes, then trigger alarm, reminds the blood in syringe to be polluted.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model syringe.
Fig. 2 is the structural representation of gripping mechanism.
Fig. 3 is the using state schematic diagram of gripping mechanism.
In figure: 1-syringe, 2-piston core bar, 3-flexible pipe, 4-gripping mechanism (the upper card article of 4.1-, 4.2-upper fastener, 4.3-card, 4.4-grab, card article under 4.5-, 4.6-lower fastener), 5-hard connection tube, 6-lever, 7-syringe needle.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, this utility model syringe comprises syringe 1 and piston core bar 2, and syringe 1 front end (in figure right-hand member) has the mouth of pipe, and mouth of pipe place is connected with flexible pipe 3, and piston core bar 2 is placed in syringe 1 from syringe 1 rear end (figure left end).
This syringe also comprises hard connection tube 5 and gripping mechanism 4, and wherein, one end of hard connection tube 5 is connected with another mouth of pipe of flexible pipe 3, and the other end of hard connection tube 5 is connected with syringe needle 7.In this utility model, hard connection tube 5 is fixedly connected with lever 6.As a kind of preferred implementation of the present utility model, lever 6 is trapezoidal block structure, and base on it (short) is connected 5 pipes with hard and is fixedly connected with.Upper base ratio due to trapezoidal block structure is gone to the bottom the length of side, therefore, is conducive to holding and clutches this lever, thus is convenient to medical personnel and stably operates, and avoids appearance operate unstable and puncture the situation of patient's blood vessel.
For the ease of the blood of extraction is isolated from the outside, this utility model is also provided with gripping mechanism 4, and as shown in Figure 2, gripping mechanism 4 comprises card article 4.1 and lower card article 4.5, upper card article 4.1 is provided with the upper fastener 4.2 protruded downwards, and lower card article 4.5 is provided with lower fastener 4.6 protruding upward.In the present embodiment, upper card article 4.1 and lower card article 4.5 are made for elastomeric material, and the left end of upper card article 4.1 is connected with the left end of lower card article 4.5, also can integration system integrally.
The right-hand member of upper card article 4.1 is engaged by buckle with the right-hand member of lower card article 4.5, in the present embodiment, buckle structure comprises the card 4.3 raised up being arranged on card article 4.1 right-hand member place, and be arranged on the grab 4.4 of right-hand member of lower card article 4.5, due to card article 4.1 and lower card article 4.5 for elastomeric material is made, therefore, it is possible to the right-hand member of card article 4.5 right-hand member upwards card article 4.1 is close under being convenient to pull-up, until grab 4.4 is snapped onto on card article 4.3, thus realize upper card article 4.1 and lower card article 4.5 to engage.When upper card article 4.1 engages with lower card article 4.5, upper fastener 4.2 and lower fastener 4.6 are near to linking together.
