Above-mentioned hydrothorax aspirator, the blunt circle of the needle point of described puncture needle, the needle body of close needle point is provided with 1～2 side opening.
Above-mentioned hydrothorax aspirator, 5～10 millimeters of described valve block internal diameters, long 10～20 millimeters of valve body, described spool cylindrical wall length is less than 2～4 millimeters of valve body length, 0.8～1.2 millimeter of disk core through-hole diameter, the via area summation is less than 1/2nd of the disk core area, and the feed tube diameter is less than or equal to 1/2nd of valve block internal diameter.
Above-mentioned hydrothorax aspirator, described liquid storage container are the bag shape, and the liquid storage mouth on its top is communicated with conduit, and its underpart is provided with discharging tube, and pipe is provided with block.
The design that provides according to this utility model, when implementing hydrothorax extraction art for the patient, suction hydrops process can be carried out continuously, saved the complicated process that repeatedly syringe to be separated with conduit and to dock, easy to operate and safe, reliability is high, and can avoid because of operate miss cause curing the originality pneumothorax takes place may.This utility model improves puncture needle, and the blunt circle of needle point is provided with side opening in the needle body end, is convenient to hydrops and enters needle body from different directions, has overcome the puncture needle needle point and has sharply punctured the drawback that visceral pleura and pleura cover pinpoint inclined plane obstruction suction easily.Use this utility model can shorten operating time, reduce the patient suffering.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the partial enlarged view at Fig. 1 needle point position;
Fig. 3 is the front view of spool;
Fig. 4 is the left view of Fig. 3.
The specific embodiment
Referring to Fig. 1, this utility model is communicated with syringe 1, conduit 5 and conduit 6 by a three way cock 2.Conduit 5 one ends connect check valve 3, and an end of conduit 6 connects check valve 4; Two check valves respectively are communicated with puncture needle 10 and liquid storage containers 9 by conduit 7,8.Can select the check valve of different structure for use, but the results showed, used check valve is a preferred version in the present embodiment, and its valve body 3-1,4-1 are cylindric, and spool 3-2,4-2 are as shown in Figure 3, Figure 4.
Operation principle of the present utility model is as follows: during the suction hydrothorax, puncture needle is thrust in the thoracic cavity, the push rod of pulling syringe, spool 3-2, the 4-2 of check valve 3,4 move right under the effect of suction force, the spool 4-2 of check valve 4 blocks feed tube 4-3, and the spool 3-2 of check valve 3 moves to right and opens, and patient's hydrothorax is drawn in the syringe by conduit 7, check valve 3, conduit 5.Pushing syringe push rod then, the spool of check valve 3,4 moves to left under the effect of motive force, the spool 3-2 of check valve 3 closes feed tube 3-3, and the spool 4-2 of check valve 4 moves to left and opens, and the hydrops in the syringe is arranged to liquid storage container 9 by conduit 6, check valve 4, conduit 8.
Check valve adopts medical macromolecular materials to make, and its spool adopts the structure that disk core 17 is inlaid in cylindrical wall 16 middle parts, and the both sides of disk core constitute cavity, and this cavity is used for storing up a small amount of coagulum and the slough tissue of staying from body cavity.The length dimension of cavity should probe into the length of valve body part less than feed tube, can compress feed tube to guarantee the disk core.2～4 through holes 18 of the edge uniform distribution of disk core are three through holes among Fig. 4.The summation of via area is less than 1/2nd of disk core area, guarantees tight the covering on the socket of the disk core no bore portion of central authorities, and guarantees that the disk core has enough big lifting surface area.Cylindrical wall and valve block internal diameter matched in clearance can axially be slided in valve body.
The needle point circle of the used puncture needle of this utility model is blunt, prevents to puncture visceral pleura.Referring to Fig. 4, be provided with 1～2 side opening 15 at position near needle point, avoid causing the suction failure because of visceral pleura covers pinpoint inclined plane.
Liquid storage container 9 is set, and the bottom of liquid storage container is provided with discharging tube 11, and pipe is provided with block 12, behind the liquid storage container full of liquid, opens block liquid is emitted.
Main part of the present utility model: syringe, three way cock, check valve and conduit, the usefulness that also can be used for other Celom liquid loading suction, body cavity flushing, body cavity injection, pneumothorax treatment and make up a prescription.
