[0032] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0033] Please refer to Figures 1-4 The present application provides the following technical solutions: a pressurized atomization device, comprising an elastic braided hose 1 connected to a spray head and a peristaltic pump 2 for increasing the pressure of the liquid in the elastic braided hose 1. The increase in the pressure of the liquid in the elastic braided hose 1 by the peristaltic pump 2 does not exceed 2.07 MPa, and the pressure resistance value of the elastic braided hose 1 does not exceed 2.07 MPa.

[0034] As an optional implementation of the utility model, by reducing the pressure resistance value of the elastic braided hose 1 and the output pressure of the peristaltic pump 2, the pressurized liquid is output to the spray head at a pressure not exceeding 2.07MPa, so that the pressure of the spray formed by the liquid in the spray head is reduced compared with the existing pressurized atomization equipment, and the patient is not easily injured by aerosol penetrating the tumor during treatment, therefore, this pressure is more suitable for the treatment of conventional tumors, and the safety is higher, and the requirement for the consumables of the elastic braided hose 1 as the infusion tube is also lower, avoiding the waste caused by using higher cost consumables during conventional treatment, therefore, it is also beneficial to reduce the cost of consumables.

[0035] Through the above structure, a pressurized atomization equipment more suitable for general conventional tumor atomization treatment is formed, which is safer and has lower requirements for consumables compared with directly using the existing high-pressure atomization treatment method, which is beneficial to save costs.

[0036] Specifically, the liquid pressure in the elastic braided hose 1 is increased by the peristaltic pump 2 not more than 2MPa, and the pressure resistance value of the elastic braided hose 1 is not more than 2MPa.

[0037] As an optional implementation of the utility model, the liquid pressure not more than 2MPa is more safe compared with the liquid output pressure of 2.07MPa.

[0038] Specifically, the liquid pressure in the elastic braided hose 1 is increased by the peristaltic pump 2 not less than 1.38MPa, and the pressure resistance value of the elastic braided hose 1 is not less than 1.38MPa.

[0039] As an optional implementation of the utility model, when the liquid output pressure is less than 1.38MPa, the formed atomization aerosol effect is very low, and more liquid medicine is required to complete the treatment, and even so, it is difficult to meet the treatment requirements of the lightest tumor, therefore, only when the liquid output pressure reaches 1.38MPa and above can the conditions for pressurized atomization treatment in the body cavity be met.

[0040] As shown in Figure 1 , it also includes a rack 3 for installing the peristaltic pump 2, and the rack 3 is provided with a pipe clamp 36 for clamping the elastic braided hose 1.

[0041] As an optional implementation of the utility model, the pipe clamp 36 is used to detachably fix the two ends of the elastic braided hose 1 on the peristaltic pump 2, so as to avoid the influence of the falling state of the elastic braided hose 1 on the liquidity of the liquid.

[0042] As shown in Figures 2-3 , the peristaltic pump 2 includes:

[0043] A pump head 21 is provided with a plurality of rollers 22, and the pump head 21 is rotationally connected to the frame 3;

[0044] A pump cover 23 comprises a fixed cover 231 and a sliding cover 232, the fixed cover 231 is fixedly connected to the frame 3, and the sliding cover 232 is slidingly connected to the frame 3;

[0045] The elastic braided hose 1 is placed between the rollers 22 through the sliding of the sliding cover 232, and the pump head 21 is connected with a motor 24 at an end away from the rollers 22.

[0046] As an optional embodiment of the utility model, when the motor 24 operates, the pump head 21 is driven to rotate, so that the elastic braided hose 1 between the sliding cover 232 and the rollers 22 is extruded by the rollers 22, and the liquid in the infusion bag is pressurized and delivered to the spray head at the other end.

[0047] As shown in Figure 4 , the sliding cover 232 is located above the fixed cover 231, and the frame 3 is provided with a limiting groove 31 for slidingly installing the sliding cover 232.

[0048] As an optional embodiment of the utility model, the sliding cover 232 slides up and down in the limiting groove 31, so that the pump cover 23 is opened and closed, so as to install or take out the elastic braided hose 1.

[0049] As shown in Figures 2-4 , the sliding cover 232 is rotationally connected with an L-shaped pull rod 25, the frame 3 is provided with a waist-shaped hole 32, one end of the pull rod 25 is fixedly connected with a roller 26 after penetrating through the waist-shaped hole 32, the pull rod 25 is connected at an eccentric position of the roller 26, and the roller 26 is movably connected to a groove 33 at the rear end of the waist-shaped hole 32 in the frame 3, the inner walls of the upper and lower sides of the groove 33 match the outer diameter of the roller 26, so that the pull rod 25 slides up and down in the waist-shaped hole 32 when rotating, thereby driving the sliding cover 232 to move.

[0050] As an optional embodiment of the utility model, when the elastic braided hose 1 needs to be put in or taken out, the pull rod 25 is rotated, and the roller 26 rolls in the groove 33, and since the pull rod 25 is blocked by the waist-shaped hole 32, the pull rod 25 installed at the eccentric position of the roller 26 can only move up and down in the waist-shaped hole 32, thereby driving the sliding cover 232 to move up and down. The advantage of this way of opening the sliding cover 232 is that the medical staff can more conveniently open and close.

[0051] Further, the skilled in the art can also set the fastening mechanism for preventing the free rotation of the dial lever 25 in the sliding cover 232, for example, the buckle, when the dial lever 25 is rotated to the position, the fastening mechanism automatically clamps the dial lever 25, thereby preventing the sliding cover 232 from being opened due to the stress caused by the extrusion of the roller 22 on the elastic braided hose 1 in the peristaltic pump 2.

[0052] As shown in Figure 2 The elastic braided hose 1 is provided with two clamps 11 which can be installed on both sides of the fixed cover 231.

[0053] As an optional embodiment of the utility model, the two clamps 11 make the distance between the elastic braided hoses 1 a fixed value, and are fixedly connected with the braided hose, so that the elastic braided hose 1 installed on the peristaltic pump 2 cannot be moved due to the rotation of the pump head 21, and the corresponding sliding cover 232 can also be provided with a groove corresponding to the clamp 11 to make the installation of the clamp 11 more firm and stable.

[0054] As shown in Figure 1 The bottom of the rack 3 is provided with a plurality of universal wheels 34 with brake function, which facilitates the movement of the peristaltic pump 2 by medical staff.

[0055] As shown in Figure 1 The rack 3 is also provided with a display 37 with an operation interface, and the display 37 is electrically connected with the motor 24.

[0056] As shown in Figure 1 The rack 3 is provided with a hanger 35 for hooking the infusion bag, which facilitates the mounting of the infusion bag.

[0057] The working principle and use process of the utility model are as follows: the clamp 11 is installed between the roller 22 and the sliding cover 232, the dial lever 25 is rotated to make the sliding cover 232 descend and fix the elastic braided hose 1, after the two ends of the elastic braided hose 1 are connected with the spray head and the infusion bag, the peristaltic pump 2 is started, and the patient can be treated for body cavity nebulization. During treatment, the pressurized liquid is output to the patient's body at a pressure of 1.38-2.07 MPa, and the aerosol is not easy to penetrate the tumor, so that the patient is not injured in the non-diseased part, therefore, this pressure is more suitable for the treatment of conventional tumors, and the safety is higher, and the requirement for the consumables of the elastic braided hose 1 is also lower, avoiding the waste caused by the use of higher-cost consumables during conventional treatment.

[0058] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application, shall be included within the scope of the present application.
