Abstract
Description
Technical Field
[0001] The utility model patent relates to the field of medical device technology, in particular to a patch that is convenient for the use of liquid medicine. Background Art
[0002] Existing drug patches are mostly applied on demand and at a fixed time by pre-setting liquid capsules, solid preparations or drug storage structures under the waterproof top layer. Drugs can also be directly combined with the permeable layer to form drug patches. Most of these products are produced on a molding production line, that is, the drug loading step has been completed before leaving the factory. For some traditional or new liquid drugs that have not been developed for timed and fixed-quantity application, it takes a certain period of time to pair such products for clinical use, and the product launch is delayed. The traditional one-time liquid addition operation of the clinical application requires a dedicated person to supervise the timed tearing, which is inconvenient, and this type of application can only be operated in one direction. After the liquid is added, the drug action time depends on the permeation rate of the permeable layer, and the duration of action cannot be adjusted independently; the drug needs to be torn off after the application time ends, and the secondary application requires a new patch, which increases the consumption of medical consumables. Therefore, a timed and quantitative device for conveniently adding liquid drugs is needed to meet the needs of rapid conversion of timed and quantitative application of liquid drugs or multiple intermittent applications.

[0021] The orthographic projection of the permeable layer 2 is smaller than the orthographic projection of the waterproof top layer 1. The edge of the waterproof top layer 1 extends downward to close the edge side of the permeable layer 2 to achieve circumferential seepage prevention of the application body. The waterproof top layer is covered with an adhesive layer, which is a pressure-sensitive adhesive layer. The orthographic projection area of the permeable layer is less than 85% of the orthographic projection area of the waterproof top layer.
[0022] When in use, tear off the release paper, align the permeable layer with the active area and adhere the dressing body to the skin surface; after the adhesion is completed, add the liquid medicine into the storage device according to the amount, and control the flow rate and input start and stop of the liquid medicine through the flow rate regulator to achieve the application effect of timed, quantitative and controllable drug flow rate; for the first use of different liquid medicines, the dispersion rate and action time in the permeable layer can be tested by the flow rate regulator for self-adjustment before use.
[0023] The catheter 4 is partially exposed from the dressing body, and the waterproof top layer 1 is provided with an opening 11 for the catheter 4 to penetrate the permeable layer 2, so as to facilitate the input of the liquid medicine in the catheter. The end of the catheter 4 communicating with the permeable layer 2 is the liquid outlet end, and the liquid outlet end is embedded in the permeable layer 2 to facilitate the rapid dispersion of the liquid medicine in the permeable layer. The liquid outlet end is also connected to a T-shaped branch pipe 421 or a Y-shaped branch pipe 422 to ensure the multi-directional dispersion of the liquid medicine. Such branches can be pre-buried before the permeable layer and the waterproof top layer are bonded. When used, the finished product can be selected according to the requirements of the action site, or the liquid outlet end is connected to a hose needle. Such catheters are packaged separately from the dressing body and shipped from the factory. When used, the hose needle can be embedded in the permeable layer, and the catheter and the waterproof top layer can be fixed twice with medical tape to avoid displacement of the hose needle and reduce the foreign body sensation of the catheter. It is suitable for application to sensitive parts or the bending parts of the action joints. The hose needle can be an intravenous indwelling needle.
[0024] Furthermore, the liquid outlet end is a C-shaped tube embedded in the permeable layer, and a plurality of through holes connecting the tube cavity and the permeable layer are distributed on the tube wall of the C-shaped tube.
[0025] The flow rate regulator 5 is a Robert clamp or a medical water stop clamp, which uses common consumables to reduce the difficulty of medical operation and production costs.
[0026] Furthermore, the permeable layer may be medical gel or medical cotton yarn with permeability.
[0027] One embodiment of the storage device of the utility model is a liquid medicine box 31, the bottom of the liquid medicine box 31 is glued to the upper surface of the waterproof top layer 1, the liquid filling port 300 is located at the top of the liquid medicine box 31, and a box cover 311 is screwed on the liquid filling port 300. The inner cavity of the liquid medicine box 31 includes a liquid filling cavity 301 and a liquid outlet pipeline 302 arranged in sequence from top to bottom, one end of the liquid outlet pipeline 302 is connected to the bottom of the liquid filling cavity 300, and the other end is connected to the liquid outlet, the liquid outlet is located on the outer wall of the liquid medicine box 31, and the catheter 4 is connected to the liquid outlet by plugging. The liquid outlet is provided with an elastic sealing ring 312, and the outer diameter of the catheter 4 is interference fit with the inner diameter of the elastic sealing ring 312 to achieve a sealed plug-in connection between the catheter 4 and the liquid outlet.
[0028] Furthermore, the cross-section of the lower portion of the liquid adding chamber is in the shape of a funnel that is larger at the top and smaller at the bottom.
[0029] Furthermore, the medicine liquid box can be made into a transparent or opaque medicine liquid box according to the storage requirements of liquid medicines; the inner wall of the medicine liquid box is printed with scale marks.
[0030] Another embodiment of the storage device of the utility model is a soft medicine bag 32, which is adhered to the upper surface of the waterproof top layer 1, and the liquid filling port 300 is located on the upper surface of the soft medicine bag 32. The upper surface of the soft medicine bag 32 is integrally connected with a soft plug 321 for sealing the liquid filling port 300, and the liquid filling or sealing operation is achieved by plugging and pulling out the soft plug 321.
[0031] The lower part of the soft medicine bag is integrally connected with a catheter that is connected to the hollow inner cavity of the soft medicine bag. The soft medicine bag is made of a soft elastic shrink material, such as medical silicone or medical rubber. The soft medicine bag is convenient for guiding the outflow of liquid medicine on various inclined surfaces, and can be deformed by external pressure to promote the release of retained liquid medicine into the catheter, thereby avoiding the phenomenon that the liquid medicine retained in the inner cavity of the storage device cannot enter the catheter due to being applied to the inclined surface.
