Embodiment 1

[0020] Example 1, see figure 1 , a pre-filled catheter flusher, comprising an outer casing 1, a piston 2 sealed and movably connected in the outer casing, and a core rod 3 that is connected to the piston and protrudes from one end of the piston. The other end of the outer casing is provided with a liquid outlet 4 and an inner thread sleeve 5 sleeved on the outside of the liquid outlet. A cap 6 for closing the liquid outlet is detachably connected to the liquid outlet. A normal saline storage cavity 8 is formed between the jacket, the piston and the liquid outlet. The physiological saline is stored in the physiological saline storage cavity. The cap includes a threaded pipe segment 61 and a gripping means 62 arranged in sequence. The threaded pipe section 61 is sleeved on the liquid outlet. The outer threaded pipe section is threadedly connected in the inner threaded sleeve to close the liquid outlet.

[0021] When rinsing, remove the cap, connect the outlet nozzle to the ...

Embodiment 2

[0023] Embodiment two, the difference with embodiment one is:

[0024] see figure 2 and image 3 , the cap is also provided with a sealing film 63 . The cap seals off the spout by sealing against the port of the spout with a sealing membrane. The grasping means are also tubular structures. The inner space of the grasping means constitutes an air hole 64 on the outer surface of the cap which communicates with the surface of the side of the sealing membrane away from the liquid outlet, so that the membrane is exposed in opening. Under the action of the pressure difference between the inside and outside of the physiological saline storage cavity, the sealing film is recessed toward the inside of the liquid outlet to close the port of the liquid outlet. The core rod and the outer casing are fixed together by the positioning structure 7 .

[0025] The positioning structure 7 includes a drive rod mounting hole 71 extending along the axial direction of the core rod and passing ...

Abstract

The invention relates to a pre-filling type catheter flusher. The pre-filling type catheter flusher comprises an outer sleeve, a piston and a core rod, wherein the piston is sealed and movably connected in the outer sleeve, and the core rod is connected to the piston and extends from one end of the piston. A liquid outlet nozzle is arranged at the other end of the outer sleeve, a liquid outlet nozzle is detachably connected with a cap for sealing the liquid outlet nozzle, a normal saline storage cavity is formed between the outer sleeve, the piston and the liquid outlet nozzle, and normal saline is stored in the normal saline storage cavity. According to the pre-filling type catheter flusher, the problems of long consumed time and large waste due to the fact that an existing injector performs the current extraction of normal saline for flushing are solved.

Description

technical field [0001] The invention relates to medical equipment, in particular to a cleaning device, a pre-filled catheter washer and a method for assembling and outputting the pre-filled catheter washer. Background technique [0002] In order to prevent the incompatibility of different drugs and the irritation of local blood vessels caused by the residual drug in the catheter when different drugs are injected through the same catheter, the catheter needs to be flushed. The existing method of flushing the catheter is realized by opening the whole pack of physiological saline, then withdrawing part of it through a syringe, and then injecting the physiological saline into the catheter. Therefore, the existing method of flushing the catheter by using a syringe to remove the physiological saline has the following deficiencies: the physiological saline needs to be drawn before the flushing can be performed, so the flushing operation requires a long time; since the amount of phy...
