[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1: Please see Figures 1-5 This invention discloses a pressure-free indwelling needle fixation film, which is applied to the film body 1 of a traditional indwelling needle fixation film, such as... Figure 1 As shown, its main body is a cover cylinder 2 that can be placed on the membrane body 1; In this embodiment, a wing ring 3 is fixedly installed on the side of the bottom of the cover cylinder 2. The bottom of the wing ring 3 is provided with an adhesive ring 4. The adhesive ring 4 is used to stick to the membrane body 1, so that the cover cylinder 2 can be fixed on the membrane body 1, providing a basis for subsequent pressure hemostasis. like Figure 2 As shown, a pressure plate 6 is installed inside the cap cylinder 2, moving up and down. An annular airbag 5 is located between the pressure plate 6 and the inner top wall of the cap cylinder 2, and is connected to an inflation mechanism through a connecting pipe 7 at its top. The inflation mechanism inflates the annular airbag 5, and the expansion of the annular airbag 5 allows the pressure plate 6 to apply controlled pressure downward to the puncture point, thereby achieving pressure hemostasis after needle removal without manual pressure, reducing the operational burden on medical staff and improving the consistency of hemostasis effect. In this invention, the top surface of the cap 2 and the pressure plate 6 are both made of transparent material. Since the annular airbag 5 has an annular structure and no obstruction at the center, it is easy to observe whether there is bleeding at the puncture point, which makes it easier to judge the hemostasis effect and decide whether to continue to maintain pressure.

[0021] The present invention also provides an inflation mechanism, specifically including a hose 8, an air cylinder 9, and a movable plug 10, such as... Figure 5As shown, one end of the hose 8 is connected with the connecting pipe 7, and the other end is communicated with the air cylinder 9, and the moving plug 10 is movably arranged in the air cylinder 9, so that by controlling the movement of the moving plug 10, the annular air bag 5 can be inflated through the hose 8 and the connecting pipe 7 to realize pressure hemostasis or pressure relief; In the embodiment, a screw groove is formed on the moving plug 10, and a screw rod 11 is screwed in the screw groove, the screw rod 11 is rotatably installed on the air cylinder 9, and one end of the screw rod 11 located outside the air cylinder 9 is fixedly connected with a knob 12, and in addition, a limiting insertion slot is formed on the moving plug 10, and a limiting insertion rod is movably inserted in the limiting insertion slot, and the limiting insertion rod is fixedly installed on the inner wall of the air cylinder 9; By rotating the screw rod 11 through the knob 12, the moving plug 10 can be driven to move by the screw rod 11, and the limiting insertion rod plays a limiting role to limit the rotation of the moving plug 10 so that it can only translate. In the embodiment, the mode of driving by the screw rod 11 can accurately control the gas injection / gas extraction amount.

[0022] Embodiment two: Please refer to Figure 4 On the basis of embodiment one, in the embodiment, a side cylinder 13 is further fixedly installed on the side of the cover cylinder 2, and a piston 14 is movably arranged in the side cylinder 13, like Figure 4 The bottom of the side cylinder 13 is provided with an insertion pipe 17, and the membrane body 1 is provided with a pipe sleeve 18 for inserting the insertion pipe 17, and the pipe sleeve 18 is communicated with a plurality of micro air grooves 19 formed on the bottom surface of the membrane body 1, and the plurality of micro air grooves 19 are radially formed on the bottom surface of the membrane body 1 to ensure uniform passage of gas and avoid local blockage; the diameter and number of the micro air grooves 19 can be set according to the specific size of the membrane body 1, and the diameter is preferably 0.2-0.4mm.

[0023] In use, the insertion pipe 17 is inserted into the pipe sleeve 18, and then the piston 14 is controlled to move upwards, at this time, the side cylinder 13 can extract the air between the membrane body 1 and the skin through the insertion pipe 17, the pipe sleeve 18 and the micro air grooves 19, so that the membrane body 1 is more closely attached to the skin, the fixing effect is improved, the attachment stability is enhanced, the risk of membrane displacement is reduced, and the tedious operation of manual repeated pressing is also avoided. In specific use, the membrane body 1 is preliminarily pasted, then the insertion pipe 17 is inserted into the pipe sleeve 18, and then the cover cylinder 2 is fixed on the membrane body 1 by using the pasting ring 4, and then the side cylinder 13 can be operated to extract air as needed to achieve close attachment.

[0024] The diameter of the central groove of the annular air bag 5 is preferably capable of covering the indwelling needle, so as to avoid interference of the annular air bag 5 on the indwelling needle, or the cover cylinder 2 can be removed after air extraction.

[0025] In the present application, as Figure 4As shown, the top surface of the piston 14 is connected with the top surface of the pressing plate 6 through the U-shaped rod 15, and the side cylinder 13 and the cover cylinder 2 are provided with a rod groove 16 for moving the U-shaped rod 15 up and down, so that when the pressing plate 6 moves, the piston 14 can be synchronously driven to move; In this way, when it is needed to control the piston 14 to move up, the air in the annular air bag 5 is first extracted by the air cylinder 9, so that the annular air bag 5 is deflated, and the pressing plate 6 and the piston 14 move up; When it is needed to pressurize and stop bleeding next, the annular air bag 5 is inflated by the air cylinder 9, so that the pressing plate 6 is pushed to downwardly exert pressure on the puncture point to achieve the purpose of stopping bleeding; When the air is inflated, the gas in the side cylinder 13 can be directly filled into the membrane body 1 and the skin through the cannula 17, so that the membrane body 1 is partially inflated, and the indwelling needle is conveniently taken out; Alternatively, a one-way air inlet valve can be arranged in the cannula 17, and a one-way air outlet valve 20 is installed on the outer wall of the side cylinder 13, so that the side cylinder 13 can only realize air extraction but cannot realize re-inflation, thereby avoiding unintended backflow and always stably maintaining the adhesion of the membrane body 1.

[0026] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
