Abstract

The embodiment of the invention provides a liquid storage device and coating liquid smearing equipment, and relates to medical instruments. The liquid storage device comprises a liquid carrying container, a liquid supply container, a floating piece and a plugging piece. The liquid supply container and the liquid carrying container share a side wall, and the shared side wall is provided with a liquid supply channel. The plugging piece is located in the liquid supply container. The floating piece is located in the liquid carrying container, connected with the plugging piece and used for driving the plugging piece to move along with changes of the liquid level of first liquid. Liquid needing to be loaded is divided into two parts to be contained in the liquid carrying container and the liquid supply container, and the liquid in the liquid carrying container is the first liquid used for immersing balloon catheters. The liquid in the liquid supply container is the second liquid. When the liquid level of the first liquid is lower than the preset position, the liquid supply channel is opened, the second liquid is converged into the first liquid through the liquid supply channel, and the liquid level of the first liquid rises to the preset position. Therefore, the liquid in the liquid carrying container is kept at a determined position, and the consistency of the coating coverage rate of the surfaces of the balloon catheters is ensured.

Description

technical field

[0001] The invention relates to the technical field of medical devices, in particular to a liquid storage device and coating liquid coating equipment. Background technique

[0002] Interventional therapy is an emerging discipline that has developed rapidly in recent years and integrates imaging diagnosis and clinical treatment. It has now become the three pillar clinical disciplines alongside traditional internal medicine and surgery. It can treat local lesions under the guidance and monitoring of imaging equipment such as digital subtraction angiography, CT, ultrasound and magnetic resonance. A commonly used interventional treatment scheme is to use a balloon catheter to insert the lesion in the patient's body for dilation treatment.

[0003] In order to facilitate the treatment and reduce the patient's discomfort, the surface of the balloon catheter is usually coated with a coating solution to form a coating. Usually, the production method of forming a co...

[0048] The embodiment of the present invention provides a coating liquid coating equipment, the coating liquid coating equipment includes a liquid storage device 100 and a manipulator, the liquid storage device 100 can be used to load hydrophilic coating liquid or other coating liquid for coating Therapeutic coating fluid on the surface of the balloon catheter. The manipulator is used to grab the balloon catheter to be coated and dip it into the coating liquid in the liquid storage device 100 according to the program setting.

[0049] Wherein, the liquid storage device 100 includes a liquid carrying container 1 , a liquid supply container 3 , a floating element 4 and a blocking element 5 . One end of the liquid-carrying container 1 is provided with an inlet 11 for the balloon catheter to pass through. The liquid supply container 3 and the liquid carrier container 1 have a common side wall 20 , and the common side wall 20 is provided with a liquid supply channel 21 . The liqu...

[0067] Please refer to Figure 5 with Image 6 , the embodiment of the present invention provides a liquid storage device 100, its basic structure and principle and the technical effects produced are basically the same as those of the first embodiment. The corresponding content in the embodiment. Compared with the first embodiment, the differences of this embodiment are:

[0068] In this embodiment, an installation body 23 extends outward from one end of the common side wall 20 close to the inlet 11 , and the rotating member is rotatably disposed on the installation body 23 .

[0069] Specifically, the top end of the common side wall 20 extends upwards in the vertical direction to form a mounting body 23 , and the receiving cavity 22 is disposed in the mounting body 23 , and the rotating body 62 is rotatably disposed in the receiving cavity 22 . Therefore, the connecting piece 6 is entirely located outside the entire container, which can completely prevent the liquid from f...
