The technical scheme is as follows:
in order to solve the technical problem, the utility model adopts the following technical scheme: the utility model provides a novel special syringe of PICC tube sealing, includes cylinder, rubber piston and push-and-pull rod, rubber piston with the push-and-pull rod is connected, rubber piston with the push-and-pull rod sets up in the cylinder, the cylinder is the transparent plastic material, the tip of cylinder is equipped with the connector, the periphery of connector is equipped with the screw thread, be equipped with the sign subsides on the outer wall of cylinder, the sign subsides divide into pulse sign subsides, the flat push sign subsides and stops the sign subsides, the setting of pulse sign subsides is in the middle section of cylinder, the flat push sign subsides set up the end of cylinder, stop the sign subsides and set up at the distance the terminal 1mm department of cylinder.
Will connector and PICC pipe connection, on the connector the screw thread can prevent when the injection PICC pipe from following drop on the connector, the pulse sign subsides are used for reminding medical personnel to be in rubber piston is in push away with impulse in the middle section time pulse in the cylinder the push-and-pull rod injects, the flat mark subsides of pushing away are used for reminding medical personnel to be in rubber piston is in flat push during the end section in the cylinder the push-and-pull rod injects, stop the sign subsides and be used for reminding medical personnel to be in the rubber piston distance stop the injection when the terminal 1mm department of cylinder prevents rubber piston deformation resilience produces the negative pressure.
Furthermore, the junction of cylinder with the connector is the toper, can effectively prevent to inject the back because the elastic deformation of completion in the cylinder leads to producing the negative pressure.
Furthermore, a plurality of convex rings are uniformly arranged at the corresponding positions of the middle section of the inner wall of the needle cylinder and the pulse identification sticker, the convex rings are coaxially arranged with the needle cylinder, the inner diameter of each convex ring is 1mm smaller than that of the needle cylinder, when the push-pull rod is pushed to perform injection, the rubber piston generates resistance when passing through the convex rings, the resistance disappears after passing through the convex rings, and the middle section of the rubber piston in the needle cylinder is in a pulse motion state, so that the pulse type injection effect is ensured.
Further, the volume of the needle cylinder is larger than 10m L, so that the pressure during injection tube sealing is reduced, and the PICC catheter is prevented from being burst due to the fact that the pressure during tube sealing is too high.
(III) the beneficial effects are as follows:
compared with the prior art, the utility model discloses the beneficial effect who produces is:
(1) can carry out the suggestion to medical personnel's seal a tub operation through setting up the sign subsides at the outer wall of cylinder, guarantee the exactness of seal a tub operation, reduce central venous catheter PICC pipe and take place to return the probability of blood stifled pipe.
(2) The middle section in the syringe is provided with the convex ring, so that the pulse type injection effect is further ensured during injection, and the syringe effectively assists medical staff to carry out correct tube sealing operation.
(3) The correct tube sealing effect can be ensured without using tube sealing liquid, and the cost is low.
