Description

Negative pressure drainage ball

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a negative pressure drainage ball.

Background

The negative pressure drainage ball is made of silicon rubber materials, the outer surface of the negative pressure drainage ball is very smooth and clean, obvious mechanical impurities, foreign matters and kinks do not exist, the transparency of the product can ensure that people can observe substances in the catheter to a certain degree, the wall of the catheter is uniform and soft, and the negative pressure drainage ball does not have the defects of air holes, fine gaps and the like, and is widely used for clinical negative pressure drainage and drainage liquid storage at present.

The negative pressure drainage ball is used as an external container connected with a drainage catheter inserted into the body, can conduct light negative pressure drainage, and can drain liquid out of a body position through repeated extrusion.

Among the prior art, negative pressure drainage ball often lacks effectual anti-reflux measure, still need pull down the drainage ball during suction drainage tube, causes the bloodstain to splash, and some negative pressure drainage balls go out the liquid hole and the business turn over air hole is a hole, and medical personnel need adopt pressing mode to extrude the hydrops, if improper when opening causes inside hydrops splash with strength, have polluted environment and infect medical personnel's risk.

Disclosure of Invention

The utility model mainly aims to provide a negative pressure drainage ball, which solves the problems in the prior art.

In order to achieve the purpose, the utility model adopts the technical scheme that:

the negative pressure drainage ball comprises a ball body, a plug head, a backflow prevention diaphragm joint, a backflow prevention clamp, a joint and a cap, and comprises a liquid inlet end and a liquid outlet end;

further, the feed liquor end contains the chock plug and prevents the diaphragm joint that flows backwards, prevents that the diaphragm joint that flows backwards and installs the inlet on the inside chock plug of spheroid, effectively prevents the backward flow of drainage liquid.

Furthermore, the choke plug contains tee bend and exhaust hole, all is equipped with the block on exhaust hole and the tee bend, drainage apparatus such as drainage tube are connected to one end, and suction devices such as syringe can be connected to the other end lift off the block, and the nurse suction is convenient.

Further, the spheroid is the silica gel material, and the spheroid surface is provided with the scale that shows capacity, but by the fast recovery original state after the extrusion deformation, the spheroid lower extreme is equipped with the leakage fluid dram, afterbody erection joint, connects liquid collecting devices such as the connectable collection liquid bag.

Furthermore, a liquid outlet at the lower end of the ball body is provided with a flow stopping clamp. And closing the flow stopping clamp, pressing the ball body to discharge air from the exhaust port, screwing the cap of the exhaust port, and extruding the ball body to form negative pressure to suck the effusion out of the patient.

The utility model has the advantages that:

1. three pass band block on the chock plug, the inside anti-backflow diaphragm joint of chock plug, when needing the suction, can directly unscrew the block, connect the syringe, the nurse suction is convenient, need not anxious hydrops backward flow.

2. In use closes and ends the class clamp, twists the block cap on the joint, can not carry liquid collecting device such as drainage bag, and is small, convenient to carry, and the early recovery of the postoperative of being convenient for is taken exercise, reduces medical personnel's work load, shortens average time in hospital.

When discharging the hydrops in the drainage ball, connect album of liquid devices such as liquid bag on connecting, unscrew the block cap on the exhaust hole, make inside and outside atmospheric pressure balanced, the volume of record hydrops opens and ends the flow clamp, need not extrude the drainage ball, and inside hydrops will be discharged the collection liquid bag thereupon. Some drainage ball exhaust holes and liquid discharge holes are the same hole, and the accumulated liquid can be discharged only by extruding the drainage ball, so that the drainage ball can splash. The utility model effectively solves the problem of drainage effusion splashing.

Detailed Description

In order to make the technical means, objectives and functions of the present invention easy to understand, the present invention will be further described with reference to the following embodiments.

As shown in figure 1, the negative pressure drainage ball of the utility model comprises a ball body 1, a plug 2, a backflow prevention diaphragm joint 3, a backflow prevention clamp 4, a joint 6 and caps (51, 52 and 53), wherein the ball body 1 is made of elastic materials, a hollow internal space is formed inside the ball body 1, and the plug 2 and the ball body 1 are hermetically installed. The cap 51 on the plug 2 is opened, the ball 1 is pressed to deform, the air in the inner space is discharged, the cap 51 is closed, the pressure applied on the ball 1 is removed, negative pressure is formed inside the ball 1 in a deformation and recovery state, and then negative pressure drainage can be performed on accumulated liquid.

When the hydrops in spheroid 1 reachs a quantitative, can open block 51 once more and make inside and outside atmospheric pressure balanced, unscrew block 53, connect album liquid devices such as liquid bag of 6 connections, 1 external surface of spheroid is equipped with the capacity scale, records the volume of hydrops, opens and ends the clamp 4 that flows, need not the extrusion and can make inside hydrops discharge to album liquid bag in, need not worry the splash problem that takes place when the drainage ball just can discharge the hydrops. After the hydrops is discharged, close and stop the clamp 4, lift the album of liquid bag off, screw on block 53, press spheroid 1 discharge inside air once more, screw on block 51, carry out the negative pressure drainage to the hydrops once more.

Three pass band block 52 on the cock 2, cock 2 internally mounted prevent the diaphragm joint 3 that flows backwards, prevent that the diaphragm joint 3 that flows backwards installs on the inside cock 2 of spheroid 1, effectively prevent the backward flow of drainage liquid. When suction is needed, the cap 52 can be directly unscrewed and connected with a syringe, so that a nurse can conveniently suck and does not need to worry about the backflow of accumulated liquid.

In use, close and only press from both sides 4, twist block 53 on the joint 6, can not carry liquid collecting device such as drainage bag, small, convenient to carry, the early recovery exercise of postoperative of being convenient for reduces medical personnel's work load, shortens average time of being in hospital.

The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the present invention, but that various changes and modifications may be made without departing from the spirit and scope of the utility model, which is defined by the appended claims and their equivalents.
