Description

Technical Field

[0001] The utility model relates to the field of indwelling needles, and in particular to an integrated fixed indwelling needle film. Background Art

[0002] Indwelling needle film is a medical material widely used in intravenous infusion. It is used to isolate bacteria and air, while reducing the stimulation of mechanical friction such as pulling and sliding.

[0003] After sticking the indwelling needle patch on the skin, the patient can wash his hands and face, etc., but the edge of the patch is prone to warping during physical activities. The warped edge of the patch means that the sealing effect is poor, and water can easily enter, which can easily lead to needle port infection. At the same time, when sticking the patch, the transparent tee at the tail of the plastic hose of the indwelling needle is large, and there is less distance under the film when the film is applied. If it is rubbed, it is very easy to cause the film to warp and expose the transparent tee, and air, water, bacteria, etc. can easily enter, affecting the patient's treatment. How to invent an integrated fixed indwelling needle patch to improve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides an integrated fixed indwelling needle film, which aims to improve the problem that the film edge warps during limb movement, resulting in poor sealing effect, and the small distance below the film when the film is applied, which easily causes the film to warp and leak through the transparent three-way, making it easy for air, water, bacteria, etc. to enter.

The extension sheet 112 is located below the diaphragm 111. The sealing fitting assembly 120 includes a sealing adhesive ring 121. The sealing adhesive ring 121 is fixedly installed at the bottom of the diaphragm 111. The sealing adhesive ring 121 is used to increase the adhesiveness to prevent external bacteria from entering and causing infection when the diaphragm 111 is warped. The extension sheet 112 is used to extend the tail of the diaphragm 111 to increase the adhesion area.

[0026] See also Figure 2 and Figure 4The diaphragm assembly 110 further includes an upper side patch 113 and a lower side patch 114, which are symmetrically connected to the two sides of the diaphragm 111. The bottom of the extension piece 112 is arranged in an arc shape, and the extension piece 112 is installed at the bottom of the diaphragm 111. The extension piece 112 is located at the tail of the three-way connection away from the indwelling needle. An adhesive tape 115 is arranged above the surface of the diaphragm 111, and two adhesive tapes 115 are arranged in parallel. The adhesive tape 115 is used to position the indwelling needle and the infusion tube, and there is a certain gap between the upper side patch 113 and the lower side patch 114. There is a certain gap between the upper side patch 113 and the lower side patch 114 and the diaphragm 111 and the extension piece 112. The upper side patch 113 and the lower side patch 114 reduce the original attachment area on both sides of the diaphragm 111, making it more convenient and quick to remove, while reducing adhesion to the patient's skin, making the patient more comfortable.

At this time, the extension piece 112 is located at the tail of the indwelling needle, which increases the area of ​​the tail of the diaphragm 111 to prevent the indwelling needle from leaking. At the same time, the upper side patch 113 and the lower side patch 114 assist the diaphragm 111, and the attached area is small during removal, which is convenient and quick to remove. The sealing adhesive ring 121 increases the sealing effect of the indwelling needle and prevents the entry of air and bacteria caused by warping. The medicine ring 122 is used to disinfect the needle hole to prevent infection.
