Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically a saline pressurization device for a suction-type plasma electrode. Background Technology

[0002] In medical and nursing practice, the importance of saline bags as the foundation of irrigation and aspiration tools is self-evident. However, with the rapid development of medical technology, especially the widespread application of high-tech medical equipment such as irrigation-aspiration plasma ablation electrodes, the limitations of traditional saline bags are becoming increasingly apparent. Among these, the most prominent problem is the low irrigation and aspiration efficiency caused by insufficient pressure, which directly affects the working efficiency of irrigation-aspiration plasma ablation electrodes.

[0003] When the saline solution in the bag decreases or is affected by changes in external pressure, the flow rate slows down or even stops. This not only prolongs the patient's procedure time but may also affect the ablation effect of the plasma ablation electrode due to poor flushing and aspiration, thus impacting the overall treatment outcome. To maintain flushing and aspiration efficiency, medical staff have to frequently adjust the height of the IV stand or manually apply pressure, which not only increases their workload but may also pose safety hazards due to improper operation.

[0004] When traditional flushing ablation electrodes are in operation, the pressurization device uses an infusion stand to hang a saline bag and uses the pressure difference between high and low pressure to pressurize and deliver saline. This method will result in delayed water output and low efficiency. After more than half of the saline is consumed, the pressure will drop sharply, resulting in insufficient flushing pressure. Utility Model Content

[0005] To address the above problems, this invention provides a saline pressurization device for a flushing-type plasma electrode, which solves problems such as delayed water output, low efficiency, and insufficient pressure.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A saline pressurization device for a flushing-type plasma electrode includes a pressurization chamber, one side of which is hinged to one side of a panel; a pressurization plate is provided on the lower part of the panel via an elastic device; a placement cavity for placing a saline bag is provided inside the pressurization chamber, and the pressurization plate is used to apply pressure to the saline bag placed in the placement cavity; a through hole is provided on the placement cavity.

[0008] As a further improvement to the above technical solution, a long slot is provided on one side of the pressurization chamber, and a rotating shaft is rotatably provided at one end of the pressurization plate, the rotating shaft being slidably disposed in the long slot; the long slot is located below the hinge point between the pressurization chamber and the panel, and the long slot is arranged in a vertical direction.

[0009] As a further improvement to the above technical solution, the elastic device includes a leaf spring, the two ends of which are respectively hinged to a pressure plate and a panel.

[0010] As a further improvement to the above technical solution, the leaf spring includes a first leaf spring and a second leaf spring. The pressure plate and the panel are both provided with reinforcing ribs.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the embodiments. The description in this part is only exemplary and explanatory, and should not be used to limit the protection scope of this utility model in any way. Example

[0023] like Figure 1-7 As shown, a saline pressurization device for a flushing-type plasma electrode includes a pressurization chamber 3, one side of which is hinged to one side of a panel 4; a pressurization plate 2 is provided on the lower part of the panel 4 through an elastic device; a placement cavity for placing a saline bag 6 is provided inside the pressurization chamber 3, and the pressurization plate 2 is used to apply pressure to the saline bag 6 placed in the placement cavity; a through hole is provided on the placement cavity.

[0024] A rotating shaft 51 is provided on one side of the panel 4. A through hole 32 for mounting the rotating shaft 51 is provided on the side wall of the pressurization chamber 3. The rotating shaft 51 is rotatably disposed in the through hole 32. Retaining rings are provided at both ends of the rotating shaft 51 to limit the axial displacement of the rotating shaft 51. A rotating shaft 51 is also provided on one side of the pressure plate 2. The rotating shaft 51 of the pressure plate 2 is disposed in the elongated slot 31. Retaining rings are provided at both ends of the rotating shaft 51 of the pressure plate 2. The retaining rings are shaft retaining rings in the prior art.

[0025] As a preferred embodiment of the above, a long slot 31 is provided on one side of the pressurization chamber 3, and a rotating shaft 51 is rotatably provided on one end of the pressurization plate 2. The rotating shaft 51 is slidably disposed in the long slot 31. The long slot 31 is located below the hinge point between the pressurization chamber 3 and the panel 4, and the long slot 31 is arranged in a vertical direction.

[0026] As a preferred embodiment of the above, the elastic device includes a leaf spring 1, the two ends of which are hinged to the pressure plate 2 and the panel 4, respectively.

[0027] like Figure 6 As shown, a first groove 42 for installing the first reinforcing rib 41 is provided on the lower side of the panel 4. In this embodiment, three first reinforcing ribs 41 are provided to facilitate the installation of the leaf spring 1. The first reinforcing rib 41 is fixed to the panel 4 by one or more of welding, bolting, and bonding. A first hinge seat 43 is provided in the middle of the first reinforcing rib 41. Figure 7As shown, a second groove 22 for installing the second reinforcing rib 21 is also provided on the pressure plate 2, and the position and number of the second grooves 22 on the pressure plate 2 correspond to the position and number of the first grooves 42 on the panel 4. A second hinge seat 23 is also provided on the second reinforcing rib 21 provided in the second groove 22 of the pressure plate 2, wherein the position of the second hinge seat 23 on the second reinforcing rib 21 is located at both ends of the second reinforcing rib 21, as shown. Figure 7 As shown, the second reinforcing rib 21 located in the middle and the second hinge seats 23 located on the second reinforcing ribs 21 on both sides are located at different ends of the second reinforcing rib 21.

[0028] Leaf spring 1 includes a first leaf spring 11 and a second leaf spring 12, wherein the first leaf spring 11 is disposed on the middle first reinforcing rib 41 and the second reinforcing rib 21, and the second leaf spring 12 is disposed on the first reinforcing rib 41 and the second reinforcing rib 21 on both sides; as shown Figure 2-4 As shown, the first leaf spring 11, the second leaf spring 12 and the pressure plate 2 form a triangular structure in side view. After the panel 4 is closed, due to the obstruction of the pressure plate 2 by the saline bag 6 placed in the pressure chamber 3, the leaf spring 1 will deform and thus apply pressure to the saline bag 6 through the pressure plate 2, so that the saline can flow out smoothly.

[0029] Specifically, the leaf spring 1 is the pressure source of the pressurization device. By applying force to the panel 4, it is fastened together with the pressurization chamber 3. At this time, the leaf spring 1 can output a certain pressure to the pressurization plate 2, so that the saline bag 6 can be kept in a high-pressure state.

[0030] As a preferred embodiment of the above, the leaf spring 1 includes a first leaf spring 11 and a second leaf spring 12. The pressure plate 2 and the panel 4 are both provided with reinforcing ribs. A first hinge seat 43 is provided in the middle of the reinforcing rib of the panel 4, and a second hinge seat 23 is provided at both ends of the reinforcing rib of the pressure plate 2. One end of the first leaf spring 11 and the second leaf spring 12 are hinged to the first hinge seat 43, and the other end of the first leaf spring 11 and the second leaf spring 12 are hinged to the second hinge seat 23.

[0031] As a preferred embodiment of the above, a latch is provided on the side wall of the pressurization chamber 3, and the latch is located on the other side of the hinge between the pressurization chamber 3 and the panel 4; a locking tongue is provided on the reinforcing rib provided in the middle of the panel 4.

[0032] Specifically, in this embodiment, the pressurization chamber 3 can be manufactured from lightweight materials such as injection molding and carbon fiber, and consists of the pressurization chamber 3 and a latch installed at the end of the pressurization chamber 3, as detailed below. Figure 5As shown, a pipeline passage hole is provided below the latch for the infusion tube to pass through. The latch can be an existing beetle rebound device, which, together with the locking tongue provided on the first reinforcing rib 41 in the middle of the panel 4, can lock the panel 4. The main structure is made of plastic or carbon fiber, which not only ensures the load-bearing capacity and stability of the product, but also achieves the goal of lightweighting. For easy carrying, a handle can be provided on the outer side of the pressurization chamber 3. The lifting is fixed to the pressurization chamber 3 by bolts. It can be used with an infusion stand or placed on a workbench.

[0033] In this embodiment, the pressure plate 2 and the pressure chamber 3 are connected by a rotating shaft 51, wherein the rotating shaft 51 can slide up and down within the elongated slot 31 of the pressure chamber 3, while the pressure plate 2 can rotate around the rotating shaft 51. Figure 2 As shown, when the pressure plate 2 is in its maximum open / closed state, the panel 4 is perpendicular to the bottom surface of the pressure chamber 3, facilitating the replacement of the saline bag 6. As can be seen from the partially closed state, the pressure plate 2 applies pressure from back to front, thus completely draining the fluid from the bag. When the pressure plate 2 is in its minimum open / closed state, both the panel 4 and the pressure plate 2 are parallel to the bottom surface of the pressure chamber 3, at which point the saline bag 6 has been completely drained of fluid. See details... Figures 2 to 3 As shown.
