Description

Technical Field

[0001] This invention relates to the field of medical device technology, and more specifically, to a medical recombinant collagen repair spray device. Background Technology

[0002] Repairing and caring for damaged skin barriers, superficial wounds after cosmetic procedures, and sensitive skin requires high standards for the safety, restorative properties, and ease of administration of topical preparations. Medical repair sprays with recombinant collagen as the core ingredient have excellent biocompatibility and clear repair effects, making them commonly used products in clinical and daily care. They are usually packaged in spray bottles as storage and atomization delivery carriers.

[0003] Currently, most medical recombinant collagen repair spray devices use spray bottles with press-type spray pumps. When the recombinant collagen is sprayed out, it will remain on the nozzle of the press-type spray pump. After the recombinant collagen dries, it will gradually solidify, causing the nozzle on the press-type spray pump to be blocked. Furthermore, if the recombinant collagen is exposed to the outside for a long time, it may mix with external impurities or breed bacteria. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a medical recombinant collagen repair spray device to solve the problem that recombinant collagen will gradually solidify after drying and may mix with external impurities or breed bacteria.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] A medical recombinant collagen repair spray device includes a spray bottle, a pump body, and a pump head. The pump body is mounted on the top of the spray bottle. The device also includes a sealing mechanism disposed on the surface of the pump head. The sealing mechanism includes a fixed rotating block fixedly connected to the surface of the pump head, a movable rotating block rotatably connected to the surface of the fixed rotating block, a rotating arm fixedly connected to the surface of the movable rotating block, a sealing sheet fixedly connected to the front end of the rotating arm, a rubber sealing gasket fixedly connected to the rear surface of the sealing sheet, a support plate fixedly connected to the upper surface of the movable rotating block, and a first spring fixedly connected between the support plate and the pump head.

[0007] Furthermore, two guide posts are fixedly connected to the top of the press pump head, and a pressing block is slidably sleeved on the surface of the two guide posts. A connecting rod is fixedly connected to the rear surface of the pressing block, and a rotating shaft is rotatably connected to the rear surface of the press pump head. A transmission rocker arm is rotatably connected to the surface of the rotating shaft. A push wheel is rotatably connected to the left end of the transmission rocker arm and the bottom end of the connecting rod. A second spring is fixedly connected to the bottom end of the pressing block, and the bottom end of the second spring is fixedly connected to the top of the press pump body.

[0008] Furthermore, it also includes a spray assembly disposed inside the press pump body. The spray assembly includes a nozzle opened inside the press pump body. A liquid outlet is installed inside the press pump body. The liquid outlet is connected to the rear end of the nozzle. A rotating column is rotatably connected inside the nozzle. Multiple centrifugal dispersing blades are fixedly connected to the surface of the rotating column. A gear is fixedly connected to the left end of the rotating column. A rack is fixedly connected to the upper surface of the press pump body. The rack is inserted into the interior of the press pump head, and the rack meshes with the gear.

[0009] Furthermore, a gas storage sleeve is fixedly fitted onto the surface of the spray bottle, the gas storage sleeve is filled with nitrogen, an annular piston plate is provided inside the gas storage sleeve, the annular piston plate and the gas storage sleeve form a piston assembly, a gas supply pipe is fixedly connected to the inner side wall of the gas storage sleeve, the gas storage sleeve and the spray bottle are connected through the gas supply pipe, a connecting gas pipe is connected to the top of the gas storage sleeve, and a sealing cap is threaded onto the top of the connecting gas pipe.

[0010] Furthermore, an elastic pull rope is fixedly connected to the lower surface of the annular piston plate, and the bottom end of the elastic pull rope is fixedly connected to the inner bottom end of the air storage sleeve and is in a stretched state.

[0011] Furthermore, a sealing ring is fixedly connected inside the outlet end of the gas supply pipe, a support ring is fixedly connected inside the outlet end of the gas supply pipe, a sealing plate is provided between the support ring and the sealing ring, a third spring is fixedly connected between the sealing plate and the support ring, and multiple vent holes are opened on the side of the sealing plate.

[0012] Furthermore, a sealing diaphragm is fixedly connected inside the spray bottle, which divides the inside of the spray bottle into upper and lower spaces. The upper space inside the spray bottle contains lyophilized powder, and the lower space inside the spray bottle contains solvent.

[0013] Furthermore, a cutting blade with a cross-shaped structure is slidably connected inside the spray bottle.

[0014] Furthermore, a suction tube is connected to the bottom end of the pump body, and a return spring is fixedly sleeved on the surface of the suction tube.

[0015] Furthermore, a connecting rod is fixedly connected to the surface of the cutting blade, a magnet is fixedly connected to the top of the connecting rod, and an internally threaded collar is fixedly connected to the top of the spray bottle. The internally threaded collar is located directly above the magnet, and a fixed iron block is inserted into the internal thread of the internally threaded collar. The magnet and the fixed iron block are attracted to each other by magnetic force.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] (1) This solution seals the nozzle by covering the nozzle surface with a sealing sheet and improving the sealing effect with a rubber sealing gasket, thereby preventing the nozzle from being exposed and causing the recombinant collagen to dry and solidify, which would block the nozzle on the press spray pump. It also reduces the probability of the recombinant collagen being exposed to the outside for a long time and mixing with external impurities or growing bacteria, thus improving the effectiveness and safety of the recombinant collagen.

[0018] (2) This solution differs from the traditional method of squeezing out recombinant collagen liquid by using atomizing nozzles with extremely small apertures and high pressure (which generates high pressure shear force that will damage the structure of collagen). Instead, it breaks down and throws out the recombinant collagen liquid by breaking it up, which can maintain the integrity of the collagen structure and further improve the effect of recombinant collagen.

[0019] (3) This solution allows nitrogen from inside the gas storage sleeve to enter the spray bottle. After the recombinant collagen is sprayed out, there is no need for external air to flow in to replenish it, which further reduces the probability of recombinant collagen mixing with external impurities or bacteria growing, and improves the effectiveness and safety of recombinant collagen.

[0020] (4) This solution uses nitrogen to isolate ordinary air from contact with recombinant collagen, which can achieve long-term preservation of the activity of recombinant collagen and improve the effect and safety of recombinant collagen.

[0021] (5) The upper space of the spray bottle in this solution stores the freeze-dried powder of recombinant collagen, which can extend the storage time of recombinant collagen and further improve the effect and safety of recombinant collagen. Attached Figure Description

[0036] 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.

[0037] Please see Figures 1-4A medical recombinant collagen repair spray device includes a spray bottle 1, a press pump body 201, and a press pump head 202. The press pump body 201 is installed on the top of the spray bottle 1. It also includes a sealing mechanism disposed on the surface of the press pump head 202. The sealing mechanism includes a fixed rotating block 311 fixedly connected to the surface of the press pump head 202. A movable rotating block 310 is rotatably connected to the surface of the fixed rotating block 311. A rotating arm 302 is fixedly connected to the surface of the movable rotating block 310. A sealing sheet 301 is fixedly connected to the front end of the rotating arm 302. A rubber sealing gasket is fixedly connected to the rear surface of the sealing sheet 301. A support plate 309 is fixedly connected to the upper surface of the movable rotating block 310. A first spring 308 is fixedly connected between the support plate 309 and the press pump head 202.

[0038] The top end of the press pump head 202 is fixedly connected to two guide posts 312, and a pressing block 304 is slidably sleeved on the surface of the two guide posts 312. A connecting rod 303 is fixedly connected to the rear surface of the pressing block 304. A rotating shaft 307 is rotatably connected to the rear surface of the press pump head 202. A transmission rocker arm 305 is rotatably connected to the surface of the rotating shaft 307. A push wheel 306 is rotatably connected to the left end of the transmission rocker arm 305 and the bottom end of the connecting rod 303. A second spring 313 is fixedly connected to the bottom end of the pressing block 304, and the bottom end of the second spring 313 is fixedly connected to the top end of the press pump body 201.

[0039] By adopting the above technical solution, when using the spray device to spray out recombinant collagen, the user presses the pressing block 304, causing the pressing block 304 to move downwards. At this time, the second spring 313 is in a compressed state. During the downward pressing of the pressing block 304, the connecting rod 303 can be driven to move downwards, thereby pushing the right end of the transmission rocker arm 305 to rotate downwards and the left end to rotate upwards. When the left end rotates upwards, it can pry the two ends of the rotating arm 302 to rotate upwards. At this time, the first spring 308 is in a stretched state, which can cause the sealing plate 301 to rotate upwards until it moves away from the nozzle 315 of the pump head 202. Then, continuing to press the pressing block 304 can cause the pump head 202 to press down, cooperating with the pump body 201 and the suction tube 40. 5. The recombinant collagen inside the spray bottle 1 is sprayed out. When the pump head 202 and the pressing block 304 are released, the second spring 313 can push the pressing block 304 to move upward and return to its original position. At the same time, the first spring 308 can pull the two ends of the rotating arm 302 downward to rotate it downward, so that the sealing plate 301 covers the surface of the nozzle 315 and improves the sealing effect through the rubber sealing gasket. This seals the nozzle 315, preventing the recombinant collagen from drying and solidifying due to the nozzle 315 being exposed, which would cause the nozzle on the pump to be blocked. It also reduces the probability of the recombinant collagen being exposed to the outside for a long time and mixing with external impurities or growing bacteria, thereby improving the effect and safety of the recombinant collagen.

[0040] like Figure 5 and Figure 6 As shown, it also includes a spraying assembly, which is disposed inside the press pump body 201. The spraying assembly includes a nozzle 315 opened inside the press pump body 201. A liquid outlet 316 is installed inside the press pump body 201. The liquid outlet 316 is connected to the rear end of the nozzle 315. A rotating column 319 is rotatably connected inside the nozzle 315. A plurality of centrifugal dispersing blades 314 are fixedly connected to the surface of the rotating column 319. A gear 318 is fixedly connected to the left end of the rotating column 319. A rack 317 is fixedly connected to the upper surface of the press pump body 201. The rack 317 is inserted into the interior of the press pump head 202. The rack 317 meshes with the gear 318.

[0041] By adopting the above technical solution, when the pump head 202 is pressed, the pump head 202 can drive the gear 318 to roll on the surface of the rack 317, thereby driving multiple centrifugal dispersion blades 314 to rotate rapidly. Simultaneously, during the manual downward pressing of the pump head 202, the piston moves down, the pump chamber volume decreases, the internal pressure increases, the inlet valve closes, and the outlet valve opens. The recombinant collagen in the pump chamber is pressurized and sprayed out from the outlet nozzle 316. This is a common method in existing technology and will not be elaborated upon here. When the recombinant collagen is sprayed out, it comes into contact with the high-speed rotating centrifugal dispersion blades 314, and can be dispersed by the high-speed rotation of the centrifugal dispersion blades. The dispersing blades 314 break down the recombinant collagen liquid, ejecting it as droplets from the nozzle 315. This allows the recombinant collagen to be applied to the designated area. Compared to the traditional method of squeezing out the recombinant collagen liquid using atomizing nozzles with extremely small orifices and high pressure, where the high-pressure shearing force can damage the collagen structure, the method of breaking down and ejecting the recombinant collagen liquid disperses it and evenly sprays it as droplets. This avoids the physical shearing damage to the long-chain structure of the protein caused by the high-pressure nozzle, maintains the integrity of the collagen structure, and further improves the effectiveness of the recombinant collagen.

[0042] like Figures 7-10 As shown, a gas storage sleeve 401 is fixedly fitted onto the surface of the spray bottle 1. The gas storage sleeve 401 is filled with nitrogen gas. An annular piston plate 407 is provided inside the gas storage sleeve 401. The annular piston plate 407 and the gas storage sleeve 401 form a piston assembly. A gas supply pipe 404 is fixedly connected to the inner side wall of the gas storage sleeve 401. The gas storage sleeve 401 and the spray bottle 1 are connected through the gas supply pipe 404. A connecting gas pipe 408 is connected to the top of the gas storage sleeve 401. A sealing cap 409 is threaded onto the top of the connecting gas pipe 408. An elastic pull rope 418 is fixedly connected to the lower surface of the annular piston plate 407. The bottom end of the elastic pull rope 418 is fixedly connected to the bottom end of the inside of the gas storage sleeve 401 and is in a stretched state.

[0043] The gas supply pipe 404 has a sealing ring 413 fixedly connected inside the outlet end, a support ring 415 fixedly connected inside the outlet end, a sealing plate 414 between the support ring 415 and the sealing ring 413, a third spring 416 fixedly connected between the sealing plate 414 and the support ring 415, and a plurality of vent holes 417 opened on the side of the sealing plate 414.

[0044] By adopting the above technical solution, before spraying out the recombinant collagen inside the spray bottle 1, the sealing cap 409 is removed from the connecting air tube 408. Then, the recombinant collagen is sprayed out by pressing the pump head 202. During this process, the negative pressure generated by the outflow of recombinant collagen from the spray bottle 1 initially maintains a static balance between the air pressure inside the gas storage sleeve 401 and the tension of the elastic pull rope 418. Therefore, when negative pressure is generated, the static balance is broken. Through the cooperation of the elastic pull rope 418, the nitrogen inside the gas storage sleeve 401 can be forced into the gas delivery tube 404, and the sealing plate 414 is pushed to the right, causing the sealing plate 414 to disengage from the sealing ring 413. On the surface, a pressure difference is formed at both ends of the gas supply pipe 404, which overcomes the elastic force of the third spring 416 to open the gas passage and expose the vent 417, allowing nitrogen to enter the spray bottle 1 from the gas storage sleeve 401 through the vent 417. After the recombinant collagen is sprayed out, the need for external air inflow is reduced, and the internal nitrogen is mainly used to balance the pressure, further reducing the probability of recombinant collagen mixing with external impurities or bacterial growth, thus improving the effectiveness and safety of recombinant collagen. Furthermore, by using nitrogen instead of ordinary air to contact the recombinant collagen, the activity of recombinant collagen can be preserved for a long time, improving the effectiveness and safety of recombinant collagen.

[0045] like Figure 7 and Figure 8 As shown, a sealing diaphragm 402 is fixedly connected inside the spray bottle 1, which divides the interior of the spray bottle 1 into upper and lower spaces. The upper space inside the spray bottle 1 contains freeze-dried powder, and the lower space inside the spray bottle 1 contains solvent. A cutting blade 403 is slidably connected inside the spray bottle 1. The cutting blade 403 has a cross-shaped structure. The bottom end of the press pump body 201 is connected to a suction tube 405, and a return spring is fixedly sleeved on the surface of the suction tube 405.

[0046] The cutting blade 403 is fixedly connected to a connecting rod 406, and a magnet block 410 is fixedly connected to the top end of the connecting rod 406. The top end of the spray bottle 1 is fixedly connected to an internal threaded collar 412, which is located directly above the magnet block 410. A fixed iron block 411 is inserted into the internal thread of the internal threaded collar 412, and the magnet block 410 and the fixed iron block 411 are attracted to each other by magnetic force.

[0047] By adopting the above technical solution, the upper space of the spray bottle 1 stores the freeze-dried powder of recombinant collagen, which can improve the storage time of recombinant collagen and further improve the efficacy and safety of its use. Before using the recombinant collagen, the fixing iron block 411 can be removed from the internal threaded collar 412, releasing the fixation on the magnet block 410. The cutting blade 403 can then move freely. By shaking the spray bottle 1 up and down, the cutting blade 403 can collide and cut the sealing diaphragm 402, breaking the sealing diaphragm 402. This allows the freeze-dried powder and solvent to be mixed together. The return spring can then straighten the suction tube 405, allowing the recombinant collagen to be sprayed out.

[0048] Instructions for use: First, remove the fixing block 411 from the internal threaded collar 412, and the cutting blade 403 can move freely.

[0049] Next, shake the spray bottle 1 up and down. The cutting blade 403 will collide with and cut the sealing diaphragm 402, breaking the sealing diaphragm 402 and mixing the freeze-dried powder and solvent together.

[0050] Next, remove the sealing cap 409 from the connecting air tube 408;

[0051] Next, pressing the press block 304 will cause the sealing plate 301 to rotate upward until it is removed from the nozzle 315 of the press pump head 202;

[0052] Subsequently, continue to press down the pressing block 304. Pressing the pump head 202 can drive the gear 318 to roll on the surface of the rack 317, thereby driving multiple centrifugal dispersing blades 314 to rotate rapidly.

[0053] At the same time, the piston moves down, the pump chamber volume decreases, the internal pressure increases, the inlet valve closes, the outlet valve opens, and the recombinant collagen in the pump chamber is pressurized and sprayed out from the outlet nozzle 316;

[0054] Finally, the recombinant collagen liquid is broken up by the high-speed rotating centrifugal dispersion blades 314 and thrown out of the nozzle 315 in a splashing droplet manner, so that the recombinant collagen can be applied to the designated location.

[0055] Subsequently, by utilizing the spatial changes caused by the liquid outflow, the nitrogen in the gas storage sleeve 401 is automatically replenished into the spray bottle 1 through the piston assembly, achieving full-cycle oxygen-free protection.

[0056] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
