[0027] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0028] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.
[0029] The following description, in conjunction with the accompanying drawings, further illustrates this application:
[0030] like Figures 1 to 8 As shown, this application provides a multifunctional dressing change pack, including a holding box 1 and a drug delivery device 2. The drug delivery device 2 is suitable for being placed in the holding box 1. After sterilization, the drug delivery device 2 is placed in the holding box 1 for sealed packaging, which can save space, reduce the volume of the dressing change pack, and facilitate storage.
[0031] The drug delivery device 2 includes a drug delivery body 21, a catheter 22, and a puncture head 23. The drug delivery body 21 and the puncture head 23 are respectively connected to the two ends of the catheter 22. The drug delivery body 21 is adapted to contain the drug 3. The puncture head 23 has a drug delivery channel. The puncture head 23 can pass through the scab on the surface of a long and narrow wound and penetrate into the unhealed tissue below the scab without damaging the scab as much as possible. Then, the drug delivery body 21 is adapted to deliver the drug 3 to the puncture head 23 through the catheter 22. After receiving the drug 3, the puncture head 23 is adapted to output the drug 3 through the drug delivery channel, realizing the drug delivery operation on the unhealed tissue, effectively protecting the integrity of the wound, and reducing irritation and secondary damage to the wound.
[0032] like Figure 1In the illustrated embodiment, the drug delivery body 21 includes a housing 211, a push rod 212, and a drug capsule 213. The drug capsule 213 is disposed within the housing 211, and one end of the push rod 212 is slidably disposed within the housing 211. The housing 211 is made of a rigid material, while the drug capsule 213 is made of a flexible material and can have a certain degree of elasticity. The housing 211 has elastic compression portions 2111 around the drug capsule 213. The push rod 212 is adapted to slide along the housing 211 and compress the drug capsule 213 to engage with the elastic compression portions 2111, so that the elastic compression portions 2111 protrude outward from the housing 211. The drug capsule 213 is adapted to withstand the pressure from the push rod 212 and / or the elastic compression portions 2111. When pressure is applied to 111, the drug 3 is released into the catheter 22. The purpose of setting the push rod 212 is to increase the pressure on the drug capsule 213, making it easier to release the drug 3 from the drug capsule 213 into the catheter 22. The elastic compression part 2111 takes into account the operational feedback of drug release. Using the push rod 212 to compress the drug capsule 213 may sometimes make it difficult to determine the drug release status. With the presence of the elastic compression part 2111, you can choose to continue pushing the push rod 212 to release the drug, or you can choose to directly squeeze the elastic compression part 2111 to release the drug 3. Both methods can determine the amount of drug 3 released by observing the deformation state of the elastic compression part 2111.
[0033] like Figures 1 to 3 In the embodiment shown, a shaping groove 11 is provided in the container 1. One end of the shaping groove 11 is bent to one side. The catheter 22 is adapted to be placed in the shaping groove 11, and the end of the catheter 22 near the puncture head 23 is bent. Since the depth of the slender wound is limited and the length is generally much greater than the depth, if the medication is to cover as much of the wound area as possible at one time, the puncture head 23 needs to be punctured at an angle. However, oblique puncture is easy to puncture the patient's skin. Therefore, the path of the puncture head 23 after entering the wound must be considered. The shaping groove 11 is provided in the container 1, which can be used to achieve a fixed pre-bending angle for the catheter 22. The catheter 22 guides the puncture head 23 to enter the wound and parallel to the scab on the wound surface, so as to reduce the stimulation of the wound tissue.
[0034] In some embodiments, the shaping groove 11 can bend one end of the puncture head 23 of the catheter 22 by 15°.
[0035] In some embodiments, the catheter 22 is made of medical-grade PP material, and its length can be 10 to 15 cm and its outer diameter can be 1.2 to 2 mm. In particular, a transparent material can be selected to facilitate observation of the flow state of the drug 3 in the catheter 22.
[0036] like Figures 1 to 3In the embodiment shown, a positioning groove 12 is provided inside the container 1. The positioning groove 12 is suitable for accommodating the conduit 22. Before unpacking, the conduit 22 needs to be placed in the positioning groove 12 to reduce the possibility of external force causing the conduit 22 to bend during transportation. The non-bent end of the shaping groove 11 and one end of the positioning groove 12 are connected to each other. By connecting the shaping groove 11 and the positioning groove 12, the space occupied can be reduced and the difficulty of structural forming can be reduced.
[0037] In some embodiments, the length of the catheter 22 is not less than the length of the shaping groove 11 to avoid structural interference between the drug delivery body 21 and the puncture head 23 and the shaping groove 11.
[0038] In some embodiments, the length of the catheter 22 is not less than the length of the positioning groove 12 to avoid structural interference between the drug delivery body 21 and the puncture head 23 and the positioning groove 12.
[0039] like Figures 1 to 3 In the embodiment shown, the container 1 is provided with a fixing groove 13, which is suitable for fixing the drug delivery body 21. Part of the fixing groove 13 is suitable for clamping the shell 211. Before unpacking, the drug delivery body 21 needs to be placed in the fixing groove 13 to reduce the possibility of collision contact during transportation that could cause deformation and damage to the drug delivery body 21. Part of the fixing groove 13 is suitable for forming a shield on both sides of the elastic compression part 2111, thereby reducing the possibility of compression contact during transportation that could cause deformation of the elastic compression part 2111 and thus compress the drug capsule 213, causing damage to the drug capsule 213.
[0040] In some embodiments, to further avoid the problem of drug 3 leakage caused by the elastic compression part 2111 being compressed during transportation, a protective cap can be provided at the puncture head 23 to limit the flow of drug 3 from the puncture head 23, while also protecting the puncture head 23, reducing the probability of the puncture head 23 being damaged by impact, and increasing the hygiene of the puncture head 23.
[0041] In some embodiments, one end of the push rod 212 is threadedly connected to the housing 211 inside the housing 211, and the other end of the push rod 212 is located outside the housing 211. By rotating the other end of the push rod 212, the push rod 212 can be rotated along the thread, thereby enabling the push rod 212 to move stably within the housing 211. At the same time, this design also enables the push rod 212 to overcome the reaction force generated by the deformation of the drug capsule 213. The threaded connection structure can lock the position of the push rod 212, enabling the push rod 212 to achieve stable pressurization of the drug capsule 213 and reduce the difficulty of drug 3 flowing out.
[0042] like Figure 5 and 6In the embodiment shown, the sac 213 is provided with an integrally formed one-way valve structure 2131 near the catheter 22. It is formed directly on the sac 213 during the manufacturing process of the sac 213 and can be a duckbill valve or an umbrella valve.
[0043] In some embodiments, the puncture head 23 is made of a temperature-sensitive material, particularly a medical metal material. The puncture head 23 is adapted to bend at a set temperature. In this application, the sensing temperature of the puncture head 23 is set at 32°C, which is consistent with the temperature of a wound on the human body surface. When the puncture head 23 enters the wound, it can bend to a certain extent under the influence of body temperature, so that the movement of the puncture head 23 after entering the wound can be as parallel as possible to the scab surface, reducing irritation to the wound and improving the effect of medication application.
[0044] like Figure 7 In the embodiment shown, the drug delivery channel includes a plurality of first drug delivery holes 231. The first drug delivery holes 231 are arranged in a circumferential array along the puncture head 23, preferably in an equally spaced array. The first drug delivery holes 231 are inclined away from the catheter 22. The purpose of this design is that the first drug delivery holes 231 can deliver the drug along the exit path of the puncture head 23 as the puncture head 23 is removed from the wound, thereby achieving a larger range and smoother drug delivery coverage area.
[0045] In some embodiments, the included angle between the axis of the first administration port 231 and the puncture head 23 is 45°.
[0046] like Figure 7 In the embodiment shown, the drug delivery channel includes a second drug delivery port 232, which is located at the end of the puncture head 23 away from the catheter 22. The second drug delivery port 232 is opened along the axis of the puncture head 23. The drug delivery from the second drug delivery port 232 is smoother than that from the first drug delivery port 231, but the coverage area is smaller.
[0047] like Figure 8 As shown, the specific usage of this multifunctional dressing pack is as follows: Unpack the dressing pack, remove the catheter 22 from the positioning groove 12, insert the catheter 22 into the shaping groove 11, bend the catheter 22, remove the catheter 22 and the drug delivery body 21 from the shaping groove 11 and the fixing groove 13, remove the protective cap on the puncture head 23, rotate the drug pusher 212 to push the drug pusher 212 further into the shell 211 until the drug 3 seeps out on the puncture head 23, stop rotating, use a cotton ball or other tools to wipe away the drug 3 seeping out on the puncture head 23, insert the puncture head 23 into one end of the long and narrow wound, and push the catheter 22 to move the puncture head 23 along the length of the wound. Stop when the puncture head 23 is close to the other end of the wound, gently press the elastic squeezing part 2111, and gradually pull out the catheter 22 so that the drug 3 can be released along the wound until the puncture head 23 is removed from the wound, thus completing the entire drug delivery process.
[0048] In some embodiments, the container also includes cleaning tools, protective equipment, disinfectant, clamping tools, and bandaging tools, and the container 1 is adapted to hold one or more of the cleaning tools, protective equipment, disinfectant, clamping tools, and bandaging tools.
[0049] In some embodiments, cleaning tools include cotton balls and cotton swabs for cleaning wounds, protective equipment includes disposable gloves for isolating and reducing interference, disinfectants include povidone-iodine for wound disinfection, clamping tools include tweezers and clamps for picking up cotton balls, and bandaging tools include gauze for protecting wounds and reducing infection.
