Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to an auxiliary device for medical and pharmaceutical use. Background Technology

[0002] With the development of medical technology, medication administration aids are playing an increasingly important role in disease treatment and health management. These devices aim to improve the convenience and accuracy of medication use, reduce the waste of medical resources, and enhance treatment outcomes. Although existing medical devices largely meet basic medical needs, some limitations still exist in certain specific medication administration scenarios.

[0003] Currently, many medication administration aids on the market rely heavily on manual operation, especially for the application of ointments. Healthcare professionals typically need to manually squeeze the ointment tube to apply the medication to the patient's skin. This method is not only inefficient but also makes it difficult to ensure consistent and accurate drug dosage.

[0004] The main drawback of existing technologies lies in their reliance on manual operation, which not only limits processing speed but also affects the uniformity of drug distribution. Manually squeezing out ointment often makes it difficult to ensure consistent dosage each time, leading to drug waste and uncertainty in treatment efficacy. Furthermore, manually applying medication is difficult to achieve uniform coverage, which may affect drug penetration and absorption, thus impacting treatment effectiveness. Summary of the Invention

[0005] The main objective of this invention is to provide a medical and pharmaceutical auxiliary device that can effectively solve the problems of existing devices that require medical staff to manually squeeze in the medicine, making it impossible to squeeze out the medicine from the ointment tube, resulting in waste due to incomplete manual squeezing, and the need for manual application, which leads to uneven application and affects the efficacy of the medicine.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A medical and pharmaceutical auxiliary device includes an anti-slip handle, the lower end of which is fixedly connected to a device housing. The rear part of the inner cavity of the device housing is provided with a drug dispensing structure communicating with its rear end. The front part of the inner cavity of the device housing and the lower end of the device housing are jointly provided with a coating structure. An auxiliary wheel is rotatably connected to the rear part of the lower end of the device housing.

[0009] Preferably, the shielding assembly includes a symmetrically arranged groove at the rear of the inner cavity of the device housing and two baffles slidably connected to the inner surface of the groove. Each of the two baffles has a limiting hole symmetrically arranged at the opposite ends. Each of the opposite ends of the inner surface of the groove is symmetrically fixedly connected to a limiting post that is slidably connected to the inner surface of the adjacent limiting hole. Each of the opposite ends of the two baffles is symmetrically fixedly connected to a compression spring sleeved on the outer surface of the limiting post.

[0010] Preferably, the auxiliary fixing component includes a clamping plate and symmetrically opened limiting grooves on the inner surface of the equipment housing. The upper and lower ends of the clamping plate are linearly distributed and fixedly connected with a plurality of limiting wheels that are slidably connected to the inner surface of the adjacent limiting grooves. The end of the clamping plate near the inner wall of the equipment housing on the same side is symmetrically fixedly connected with a compression spring two that is fixedly connected to the inner wall of the equipment housing. The end of the clamping plate near the connecting seat is symmetrically opened with L-shaped drive grooves that are connected by narrow slots.

[0011] Preferably, the extrusion assembly includes two rollers slidably connected to the inner surfaces of the two L-shaped drive grooves on both sides. Each of the two rollers is fixedly connected to a sliding shaft at one end close to the other. The outer surfaces of the two sliding shafts are slidably connected to a roller. The two sliding shafts are fixedly connected to a tension spring at one end close to the other. The outer surfaces of the two rollers are respectively engaged with the inner side of the extrusion drive assembly on the same side. Each of the vertical portions of the two L-shaped drive grooves on both sides away from the sliding shafts is fixedly connected to a spring plate that is flush with the horizontal portion.

[0012] Preferably, the extrusion drive assembly includes an H-shaped slider slidably connected to the inner surfaces of two L-shaped drive slots on the same side and a winding disc rotatably connected to the front of the inner cavity of the clamping plate. The upper and lower slots of the H-shaped slider are slidably connected to the outer surfaces of the rollers on the same side. The front and rear ends of the H-shaped slider are fixedly connected to a cable wound on the outer surface of the winding disc. A bevel gear set is driven to the lower part of the central shaft of the winding disc. The inner surfaces of the input sides of the spring plates on both sides are slidably connected to a drive shaft rotatably connected to the inner cavity of the equipment housing. The right end of the L-shaped drive slot is fixedly connected to a drive motor fixedly connected to the right end of the equipment housing. The drive shaft is driven to the coating structure.

[0013] Preferably, the coating structure includes a guide groove opened at the lower front of the device housing, rollers are symmetrically rotatably connected to the inner surface of the guide groove, and auxiliary plates are fixedly connected to the lower part of the device housing located behind the rollers. A connecting pipe communicating with the connecting seat is opened at the upper part of the inner cavity of the guide groove.

[0014] Preferably, the outer surface of the roller has a plurality of grooves linearly distributed thereon.

[0015] Preferably, a plurality of embedded teeth located inside the groove and in close contact with its inner surface are fixedly connected to the side of the auxiliary plate near the roller, and a rubber plate is fixedly connected to the side of the auxiliary plate away from the embedded teeth.

[0016] Preferably, the two groove center shafts are connected by a drive belt, and the groove located at the rear is connected to the drive shaft by a drive belt.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This invention seals the ointment from the external environment through the shielding component, reducing contamination of the drug by the external environment. At the same time, the connection seat and the shielding component work together to fix the drug, and the extrusion drive component and the extrusion component squeeze the drug out of the ointment tube. Simultaneously, the extrusion drive component and the transmission of the application structure drive the application structure to evenly apply the ointment delivered by the connection seat to the patient's skin. This reduces the number of operation steps for medical staff, improves the uniformity of application, reduces drug residue in the ointment tube, and improves utilization efficiency.

[0019] 2. This invention uses a drive motor to pull an H-shaped slider through a cable, which slides in the horizontal part of an L-shaped drive groove. This, in turn, causes the extrusion assembly to slide in the horizontal part of the L-shaped drive groove. The upper and lower rollers extrude the medicine from the ointment tube. At the same time, the L-shaped drive groove guides the upper and lower extrusion assemblies to maintain a minimum distance, ensuring efficient extrusion of the medicine from the ointment tube, reducing ointment residue, improving drug utilization efficiency, and reducing waste. Furthermore, the cooperation between the sliding shaft and the rollers allows for the use of ointments stored at different widths, thus expanding the applicability of the device.

[0020] 3. This invention guides the ointment into the guide channel through a connecting tube, and then into the groove through extrusion. The ointment is carried out through the groove, and at the same time, the embedded teeth scrape the ointment out of the groove so that it falls onto the patient's skin. The rubber plate spreads the ointment evenly on the patient's skin surface, improving the uniformity of drug distribution, thereby improving absorption efficiency, reducing skin contact between medical staff and patients, and reducing the risk of cross-infection.

[0034] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0035] Example 1, as Figure 1 and Figure 2 As shown, a medical and pharmaceutical auxiliary device includes an anti-slip handle 1, a device housing 2 fixedly connected to the lower end of the anti-slip handle 1, a drug squeezing structure 3 connected to the rear end of the inner cavity of the device housing 2, a coating structure 4 jointly provided at the front of the inner cavity of the device housing 2 and the lower end of the device housing 2, and an auxiliary wheel 5 rotatably connected to the rear of the lower end of the device housing 2.

[0036] Specifically, for fixing and extruding the ointment, please refer to... Figure 3 The extrusion structure 3 includes a connecting seat 37 located at the front of the inner cavity of the equipment housing 2, a shielding component 31 connected to the rear end of the inner cavity of the equipment housing 2, auxiliary fixing components 32 symmetrically arranged on the left and right sides of the inner cavity of the equipment housing 2, a compression drive component 34 jointly arranged by the two auxiliary fixing components 32 and the bottom wall of the inner cavity of the equipment housing 2, and compression components 33 symmetrically distributed and installed on the inner side of the compression drive component 34 jointly arranged on the inner surface of the two auxiliary fixing components 32, a battery compartment 35 opened at the right end of the equipment housing 2, and buttons 36 symmetrically arranged at the front and back of the upper end of the anti-slip handle 1.

[0037] The ointment pushes open the shielding component 31 and enters the inner cavity of the equipment housing 2. Its outlet is located inside the connecting seat 37. The connecting seat 37 contains a rubber ring, which can achieve the effect of sealing and slightly restricting the movement of the ointment.

[0038] Meanwhile, the auxiliary fixing components 32 on both sides can restrict the movement of the ointment, and together with the squeezing component 33, squeeze out the drug and send it into the application structure 4 through the connecting seat 37 for application. In addition, the shielding component 31 can prevent external air from entering and reduce contamination of the drug.

[0039] It should be noted that the battery compartment 35 is a conventional battery mounting structure used to install lithium batteries to provide power to the extrusion drive assembly 34. Meanwhile, the button 36 on the anti-slip handle 1 is a conventional on / off switch. Pressing it turns on the circuit and releasing it turns off the power. It is used to control the operation of the extrusion drive assembly 34. Its control method and installation method are mature technologies in conventional technology, and will not be shown or described in detail in this invention.

[0040] Furthermore, to achieve sealing of the area where the ointment is placed, refer to... Figure 4The shielding component 31 includes a sliding groove 315 symmetrically opened at the rear of the inner cavity of the equipment housing 2 and two baffles 311 slidably connected to the inner surface of the sliding groove 315. Limiting holes 312 are symmetrically opened at the ends of the two baffles 311 that are far apart from each other. Limiting posts 314 that are slidably connected to the inner surface of the adjacent limiting holes 312 are fixedly connected at the ends of the inner surface of the sliding groove 315 that are far apart from each other. Compression springs 313 sleeved on the outer surface of the limiting posts 314 are fixedly connected at the ends of the two baffles 311 that are far apart from each other.

[0041] The baffle 311 can slide in the slide groove 315. When the external ointment is pushed inward, the limiting post 314 retracts into the limiting hole 312. At this time, the compression spring 313 is compressed, and the baffle 311 slides into the slide groove 315. The two baffles 311 separate. After the medicine is pushed to the bottom and enters the connecting seat 37, the medical staff's hand is withdrawn. The baffle 311 is reset under the action of the compression spring 313, sealing the inner cavity of the equipment shell 2 with the external environment and reducing the contamination of the medicine.

[0042] Furthermore, to achieve fixation of the ointment, see [reference needed]. Figure 5 The auxiliary fixing component 32 includes a clamping plate 321 and limiting grooves 324 symmetrically opened on the inner surface of the equipment housing 2. Several limiting wheels 322 that are slidably connected to the inner surface of the adjacent limiting grooves 324 are linearly distributed and fixed at the upper and lower ends of the clamping plate 321. A compression spring 323 that is fixedly connected to the inner wall of the equipment housing 2 is symmetrically fixed at the end of the clamping plate 321 near the inner wall of the equipment housing 2. An L-shaped drive groove 325 that is symmetrically opened on the upper and lower ends of the clamping plate 321 near the connecting seat 37 and communicated through a narrow groove is provided.

[0043] When the drug enters, the clamps 321 on both sides will move away from each other until the drug reaches the bottom. At this time, the clamps 321 will be tightly attached to both sides of the drug under the action of the compression spring 323. With the help of the connecting seat 37, they will be fixed in the inner cavity of the equipment housing 2 to prevent positional displacement when the squeezing component 33 is in action.

[0044] In summary, during the operation of this embodiment, the shielding component 31 seals the ointment from the external environment, reducing contamination of the drug by the external environment. At the same time, the connecting seat 37 and the shielding component 31 work together to fix the drug. The squeezing drive component 34 and the squeezing component 33 squeeze the drug out of the ointment tube. Simultaneously, the squeezing drive component 34 and the application structure 4 drive the application structure 4 to operate, so that the ointment delivered by the connecting seat 37 is evenly applied to the patient's skin. This reduces the number of steps required by medical staff, improves the uniformity of application, reduces drug residue in the ointment tube, and improves utilization efficiency.

[0045] In Example 2, based on Example 1, the drive motor 343 drives the cable 342 to pull the H-shaped slider 341 to slide in the horizontal part of the L-shaped drive groove 325. This causes the extrusion assembly 33 to slide in the horizontal part of the L-shaped drive groove 325. The upper and lower rollers 331 squeeze out the medicine from the ointment tube. At the same time, the guiding effect of the L-shaped drive groove 325 ensures that the upper and lower extrusion assemblies 33 are at the minimum distance, ensuring the extrusion efficiency of the medicine in the ointment tube, reducing the ointment residue inside, improving the utilization efficiency of the medicine, reducing waste, and the cooperation between the sliding shaft 332 and the rollers 331 can adapt to the use of ointments with different widths, thus improving the applicability of the device.

[0046] Specifically, to achieve the extrusion of the ointment, see [link / reference]. Figure 6 , Figure 7 , Figure 8 and Figure 9 The extrusion assembly 33 includes two rollers 333 that are slidably connected to the inner surfaces of the L-shaped drive grooves 325 on both sides. Each of the two rollers 333 has a sliding shaft 332 fixedly connected to one end of each roller. The outer surfaces of the two sliding shafts 332 are slidably connected to a roller 331. The two sliding shafts 332 have a tension spring 335 fixedly connected to one end of each roller. The outer surfaces of the two rollers 333 are respectively engaged with the inner side of the extrusion drive assembly 34 on the same side. The vertical part of the L-shaped drive grooves 325 on both sides away from the sliding shafts 332 is fixedly connected to a spring plate 334 that is flush with the horizontal part.

[0047] To avoid affecting the entry of the ointment, in the initial state, the roller 333 is in the vertical part of the L-shaped drive groove 325. At this time, under the action of the spring plate 334, the roller 333 is inside the extrusion drive assembly 34. However, the contact between the extrusion drive assembly 34 and the roller 333 is not completely closed. When the medicine enters, it will push the roller 331 and the sliding shaft 332 to drive the roller 333 to slide along the vertical part of the L-shaped drive groove 325 towards the spring plate 334. At this time, the spring plate 334 is compressed, and the roller 333 enters the vertical part of the L-shaped drive groove 325, which will not block the entry of the ointment tube.

[0048] Meanwhile, in order to accommodate ointment tubes of different sizes and to adapt to the changes in the spacing between the two clamping plates 321, the sliding shaft 332 can slide on the inner surface of the roller 331. At the same time, a tension spring 335 is connected between the two sliding shafts 332 to ensure that they can maintain the tendency to move towards the minimum spacing. When the spacing between the clamping plates 321 changes, the spacing between the sliding shafts 332 increases, and the tension spring 335 is stretched, thereby accommodating the use of ointment tubes of different sizes.

[0049] Furthermore, to enable the extrusion assembly 33 to slide within the L-shaped drive groove 325, refer to... Figure 7 , Figure 8 and Figure 10 The extrusion drive assembly 34 includes an H-shaped slider 341 that is slidably connected to the inner surfaces of two L-shaped drive grooves 325 on the same side, and a winding disc 346 that is rotatably connected to the front of the inner cavity of the clamping plate 321. The upper and lower slots of the H-shaped slider 341 are slidably connected to the outer surfaces of the rollers 333 on the same side. The front and rear ends of the H-shaped slider 341 are fixedly connected to a cable 342 wound on the outer surface of the winding disc 346. The lower part of the central shaft of the winding disc 346 is driven by a bevel gear set 344. The inner surfaces of the input sides of the spring plates 334 on both sides are slidably connected to a drive shaft 345 that is rotatably connected to the inner cavity of the equipment housing 2. The right end of the L-shaped drive groove 325 is fixedly connected to a drive motor 343 that is fixedly connected to the right end of the equipment housing 2. The drive shaft 345 is driven by the coating structure 4.

[0050] The power source for the drive motor 343 is the battery installed in the battery compartment 35. The button 36 can control the forward and reverse rotation of the drive motor 343. Under this premise, the forward rotation of the drive motor 343 can drive the drive shaft 345 to rotate, thereby driving the winding disc 346 to rotate through the bevel gear set 344. When the winding disc 346 rotates, it will drive the cable 342 to move on its surface, thereby pulling the H-shaped slider 341 to slide along the horizontal part of the L-shaped drive groove 325. When sliding, the roller 333 will enter the horizontal part of the L-shaped drive groove 325. At this time, due to the limitation of the L-shaped drive groove 325, the roller 333 cannot move up and down, but can only move horizontally, thereby squeezing the ointment tube to squeeze the ointment from the connecting seat 37 into the application structure 4.

[0051] In Example 3, based on Example 2, the ointment is guided into the guide channel 41 through the connecting tube 44, and then into the groove 421 through the squeezing action. The ointment is carried out through the groove 421, and at the same time, the embedded teeth 431 scrape the ointment in the groove 421 so that it falls onto the patient's skin. The rubber plate 432 spreads the ointment evenly on the patient's skin surface, improving the uniformity of drug distribution, thereby improving the absorption efficiency, reducing the skin contact between medical staff and patients, and reducing the risk of cross-infection.

[0052] Specifically, to achieve the purpose of applying the ointment to the patient's skin, see [link to relevant documentation]. Figure 11 and Figure 12 The coating structure 4 includes a guide groove 41 at the lower front of the equipment housing 2. Rollers 42 are symmetrically rotatably connected to the inner surface of the guide groove 41. Auxiliary plates 43 are fixedly connected to the lower part of the equipment housing 2 located behind the rollers 42. A connecting pipe 44 communicating with the connecting seat 37 is provided in the upper part of the inner cavity of the guide groove 41. Several grooves 421 are linearly distributed on the outer surface of the rollers 42. The central shafts of two grooves 421 are connected by a transmission belt. The groove 421 located at the rear is connected to the drive shaft 345 by a transmission belt.

[0053] Furthermore, in order to scrape the drug out of the groove 421, a number of inserting teeth 431 located inside the groove 421 and in close contact with its inner surface are fixedly connected to the side of the auxiliary plate 43 near the roller 42, and a rubber plate 432 is fixedly connected to the side of the auxiliary plate 43 away from the inserting teeth 431.

[0054] The ointment in the connector 37 can enter the guide groove 41 through the connecting pipe 44. The ointment in the guide groove 41 gradually accumulates and is pressed into the groove 421. Although the ointment in the groove 421 can adhere to the skin, it will not completely detach. Therefore, it needs to be scraped out by the embedded teeth 431. After the ointment detaches from the groove 421, it will fall onto the patient's skin and be smoothed by the rubber plate 432, so that it is evenly spread on the patient's skin surface, achieving uniform application.

[0055] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
