Description

Technical Field

[0001] The invention relates to the technical field of medicine crushing, in particular to a medicine crushing device for critical care. Background Art

[0002] Western medicine includes organic chemicals, inorganic chemicals and biological products. Most Western medicine is basically taken in solid form. Critical care refers to the use of various advanced medical technologies to provide concentrated and intensive treatment and care for all types of critically ill patients admitted to ensure the patient's quality of life as much as possible.

[0003] Generally, when patients are given drug treatment, they are required to swallow the drugs to ensure that the drugs have a therapeutic effect in the patient's body. However, for patients in critical care, most of them are in a state of dysphagia or blurred consciousness. At this time, the patients cannot swallow the tablets by themselves, so they need to crush the drugs into powder, dissolve the drugs in water, pour the medicine into the patient's mouth, or inject them into the patient. The traditional way of crushing the drugs is that medical staff use local materials and use infusion bottles and other items to grind and crush the tablets. This method is time-consuming and labor-intensive. Now there is a device specifically used for crushing drugs. By mechanically squeezing the drugs in the form of a pestle, the drug refinement work is completed. However, this method is relatively simple. In actual use, some particles still exist in the refined drugs, which need to be further crushed by nurses. Especially when a large number of tablets need to be crushed, it is very easy to waste drugs. Therefore, the existing drug crushing device is still inconvenient in actual use, and there is still room for improvement in ensuring the quality of drug refinement and reducing the repetitive work of nurses.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] For example, see Figures 1 to 9 The present invention provides a critical care medicine crushing device, including a bracket 1, the inner wall of the bracket 1 is fixedly connected to a body 2 and a fixed cylinder 3, the inner wall of the fixed cylinder 3 is rotatably connected to a rotating frame 4, the surface of the rotating frame 4 is fixedly connected to an abrasive cylinder 5, and the surface of the fixed cylinder 3 is provided with two openings adapted to the abrasive cylinder 5.

[0020] An abrasive block 6 is arranged below the main body 2 , an auxiliary plate 7 is arranged inside the abrasive block 6 , and a knocking rod 8 is arranged inside the abrasive cylinder 5 .

[0021] The medicine crushing device further comprises a medicine crushing component, an auxiliary component and a knocking component. The medicine crushing component is arranged in the main body 2 , the auxiliary component is transmission-connected with the medicine crushing component, and the knocking component is arranged in the abrasive cylinder 5 .

[0022] In this embodiment, in the intensive care unit, if it is necessary to crush the medicine, the nurse can put the medicine into the abrasive cylinder 5 in the fixed cylinder 3, and then drive the medicine crushing component to operate. The medicine crushing component causes the medicine grinding block 6 to reciprocate and move vertically back and forth at the same time, so as to efficiently crush the medicine and make the medicine be ground into powder evenly without causing waste. In the crushing process, the medicine crushing component synchronously drives the auxiliary component to operate, so that the auxiliary plate 7 follows the vertical displacement of the medicine grinding block 6 and moves vertically back and forth in the medicine grinding block 6, so that in the process of the medicine grinding block 6 crushing, the medicine grinding block is knocked in the medicine grinding block 6. By tapping, the medicine powder on the surface of the medicine grinding block 6 can be shaken off when it is separated from the medicine, which is convenient for the subsequent collection of medicine powder and avoids the waste of medicine. After the medicine is crushed, the rotating frame 4 can be rotated, and the rotating frame 4 can simultaneously drive the abrasive cylinder 5 to rotate, so that the medicine powder inside the abrasive cylinder 5 is synchronously driven until the abrasive cylinder 5 corresponds to the opening below the fixed cylinder 3. At this time, the medicine falls out from here and the nurse can collect it. In this process, the knocking component can be operated synchronously, so that the knocking rod 8 can shake quickly, thereby causing the abrasive cylinder 5 to vibrate, which is convenient for the collection of medicine powder without the need for manual tapping by the nurse.

[0023] It is worth noting that, during the rotation of the rotating frame 4, when the abrasive cylinder 5 is offset from the opening above the fixed cylinder 3, the abrasive cylinder 5 is blocked by the inner wall of the fixed cylinder 3, and the drug powder will not leak.

[0024] See also Figure 1 The medicine crushing component includes two driving shafts 9, and the shaft arms of the two driving shafts 9 are fixedly connected with a rocker assembly 34. The surface of the rocker assembly 34 is provided with anti-skid patterns. Through the setting of the rocker assembly 34, the nurse can easily control the rotation of the driving shaft 9. By providing the anti-skid patterns, the nurse can avoid slipping, which is further convenient for use.

[0025] See also Figures 1 to 8 The two driving shafts 9 are both rotatably connected to the inner wall of the main body 2, the shaft arms of the two driving shafts 9 are fixedly connected with the rotating rod 10, the inner walls of the two rotating rods 10 are rotatably connected with the main shaft 11, the inner wall of the main body 2 is slidably connected with two limit rods 13 through the sliding assembly 12, the rod arms of the two limit rods 13 are fixedly connected with the rectangular frame 14, the inner walls of the two rectangular frames 14 are slidably connected with the shaft arms of the main shaft 11, the bottom surfaces of the two rectangular frames 14 are jointly fixedly connected with a displacement plate 15, the bottom surface of the displacement plate 15 is fixedly connected with two displacement plates 2 16, the inner walls of the two displacement plates 2 16 are slidably connected with rack rows 17, the bottom surface of the displacement plate 15 is rotatably connected with a shaft body 18, the end of the shaft body 18 is fixedly connected with a gear 19, and the teeth of the gear 19 are respectively meshed with the teeth of the two rack rows 17.

[0026] The inner wall of the main body 2 is provided with two oblique grooves 20, and the groove walls of the two oblique grooves 20 are slidably connected with guide rods 21, and the ends of the two guide rods 21 are respectively fixedly connected to the surfaces of the two rack rows 17, and the surface of the gear 19 is fixedly connected with a sleeve 22, which passes through the main body 2, and the end of the sleeve 22 is fixedly connected to the top surface of the grinding block 6.

[0027] In this embodiment, the driving shaft 9 can be rotated to make the rotating rod 10 rotate synchronously, that is, one end of the rotating rod 10 is displaced in a circle around the driving shaft 9. During this process, the driving shaft 9 on the other side is driven to rotate synchronously. At this time, the two rotating rods 10 keep synchronous movement. At this time, driven by the rotating rod 10, the main shaft 11 is displaced in a circle around the driving shaft 9. The limiting rod 13 can only be displaced in the vertical direction through the limiting component 12. That is, the torque connected to the limiting rod 13 is The rectangular frame 14 can only be displaced in the vertical direction. In this way, when the main shaft 11 is displaced in a circular trajectory with the driving shaft 9 as the axis, the rectangular frame 14 will be pushed to move back and forth in the vertical direction through the inner wall of the rectangular frame 14. During this displacement process, the main shaft 11 will slide back and forth along the inner wall of the rectangular frame 14. At the same time, the limit rod 13 will be displaced synchronously during this displacement process. During the vertical reciprocating displacement of the rectangular frame 14, the displacement plate 15 will also be synchronously displaced vertically reciprocatingly, thereby through the transmission of the displacement plate 15, The two displacement plates 16 are vertically reciprocated, so that the gear 19 and the two rack rows 17 can be synchronously moved downward through the transmission of the shaft 18. Taking a single rack row 17 as an example, during the process of synchronously moving downward with the gear 19, it will also drive the guide rod 21 to move downward, that is, the guide rod 21 slides along the groove wall of the oblique groove 20. Therefore, under the limit of the oblique groove 20, the rack row 17 can slide along the surface of the displacement plate 16 during the process of moving downward, and the other rack row 17 can be moved downward. Similarly, while the two rack rows 17 are moving downward synchronously with the gear 19, the two rack rows 17 will also move in the horizontal direction. Since the horizontal position of the gear 19 remains unchanged, the horizontal movement of the two rack rows 17 during this process can cause the gear 19 to rotate back and forth while being vertically reciprocated. At this time, through the transmission of the sleeve 22, the grinding block 6 can be driven to reciprocate while performing vertical reciprocating movement.

[0028] In this way, the movement of the grinding block 6 can be used to efficiently and fully crush the medicine in the abrasive barrel 5 until the medicine powder is formed, thereby reducing the subsequent labor intensity required of nurses while ensuring the quality of the medicine powder forming.

[0029] It is worth noting that, by symmetrically arranging the driving shafts 9, when in use, the nurse can drive the medicine grinding block 6 to move by rotating the driving shaft 9 on either side, which makes the use more convenient.

[0030] See also Figures 1 to 8The auxiliary components include a rotating drum 23, which is fixedly connected to the shaft wall of the shaft body 18. A continuous groove 24 is provided on the side wall of the rotating drum 23. A transmission rod group 25 is slidably connected to the groove wall of the continuous groove 24. A through hole for displacement of the transmission rod group 25 is provided on the surface of the displacement plate 15. The transmission rod group 25 is slidably connected to the two displacement plates 16. An auxiliary rod 26 is fixedly connected to the surface of the transmission rod group 25. The auxiliary rod 26 is slidably connected to the inner wall of the displacement plate 15. The inner walls of the shaft body 18, the gear 19 and the grinding block 6 are all provided with through holes for the auxiliary rod 26 to pass through. The end of the auxiliary rod 26 is fixedly connected to the top surface of the auxiliary plate 7.

[0031] In this embodiment, during the reciprocating rotation of the above-mentioned gear 19, the shaft body 18 is synchronously driven to reciprocate and rotate, so that through the transmission of the shaft body 18, the rotating drum 23 is synchronously reciprocated, that is, the continuous groove 24 on the rotating drum 23 is made to perform a circular motion. At this time, since the transmission rod group 25 follows the synchronous downward movement, it will be driven by the continuous groove 24 to perform a vertical reciprocating displacement relative to the shaft body 18, so that through the relative reciprocating displacement of the transmission rod group 25, the auxiliary rod 26 is synchronously driven to move, that is, through the transmission of the auxiliary rod 26, the auxiliary plate 7 follows the grinding block 6 to perform a vertical movement while performing a vertical reciprocating displacement in the grinding block 6.

[0032] In this way, during the process of the medicine grinding block 6 crushing the medicine, the medicine grinding block 6 can be tapped from the inside to shake off the medicine powder on its surface, thereby facilitating the nurses' collection of the medicine powder and further reducing the labor intensity required by the nurses, while also avoiding the waste of medicines. At the same time, compared with the knocking method mentioned in some traditional methods, this method is better because it is produced from the inside of the medicine grinding block 6.

[0033] Embodiment 2, based on the above embodiment: See also Figure 2 and Fig. 9 The knocking component includes a motor 27, which is fixedly connected to the inner wall of the abrasive cylinder 5. The output end of the motor 27 is fixedly connected to a knocking gear 28. The inner wall of the abrasive cylinder 5 is fixedly connected to a knocking limit rod 29. The rod arm of the knocking limit rod 29 is slidably connected to a tooth block 30. The teeth of the tooth block 30 are meshed with the teeth of the knocking gear 28. The knocking rod 8 is fixedly connected to the surface of the tooth block 30. The rod arm of the knocking limit rod 29 is provided with a spring 31, and the end of the spring 31 is fixedly connected to the surface of the tooth block 30.

[0034] In this embodiment, when the nurse rotates the rotating frame 4 to collect the drug powder, the motor 27 can also be started to rotate the knocking gear 28, so that the tooth block 30 slides along the rod arm of the knocking limit rod 29, and the spring 31 is stretched synchronously. When the teeth of the tooth block 30 are disengaged from the teeth of the knocking gear 28, the elastic action of the spring 31 will make the tooth block 30 mesh with the teeth of the knocking gear 28 again. This can be repeated, and the tooth block 30 can be shaken rapidly under the continuous drive of the motor 27, so that the knocking rod 8 can be shaken rapidly through the transmission of the tooth block 30, so that the abrasive barrel 5 can be continuously vibrated, thereby facilitating the collection of drug powder. There is no need for the nurse to manually tap the device, which is further convenient for the nurse to use.

[0035] Embodiment 3, based on the above embodiment: See also Figure 2 A magnet group 1 32 is embedded in the inner wall of the fixed cylinder 3 , and a magnet group 2 33 corresponding to the magnet group 1 32 is embedded in the inner wall of the rotating frame 4 .

[0036] In this embodiment, by setting the magnet group 1 32 and the magnet group 2 33, during the process of crushing the medicine, there will be no relative rotation between the fixed cylinder 3 and the rotating frame 4, and the medicine crushing process is stable. If the medicine powder needs to be taken out, the magnetic force can be overcome manually.

[0037] See also Figure 1 A splash-proof transparent ring 35 is fixedly connected to the surface of the fixed cylinder 3. The size of the splash-proof transparent ring 35 is adapted to the size of the grinding block 6. The setting of the splash-proof transparent ring 35 can ensure that no splashing occurs during the crushing process of the medicine, thereby ensuring that the medicine is not wasted.

[0038] See also Figure 1 The inner wall of the bracket 1 is fixedly connected with a placement rack 36, and a placement opening is provided on the surface of the placement rack 36. Through the arrangement of the placement rack 36 and the placement opening provided thereon, when in use, the nurse can place the disposable cup on the placement opening. When collecting the medicine powder, the powder falls directly into the disposable cup, which is convenient for the nurse to take and can be directly given to the patient orally by flushing with water.

[0039] Working principle: When the critical care medicine crushing device is used, in the intensive care unit, if medicines need to be crushed, the nurse can put the medicines into the abrasive cylinder 5 in the fixed cylinder 3, and then rotate any one of the rocker assemblies 34, so that the medicine grinding block 6 reciprocates and moves vertically back and forth at the same time, so as to efficiently crush the medicines and grind the medicines into powder evenly without causing waste. In the crushing process, the auxiliary plate 7 is synchronously driven to move, so that the auxiliary plate 7 follows the vertical displacement of the medicine grinding block 6 and moves vertically back and forth in the medicine grinding block 6, so that in the process of crushing the medicine grinding block 6, the medicine grinding block is crushed in the medicine grinding block 6. The knocking and tapping can shake off the drug powder contaminated on the surface of the grinding block 6 when it is separated from the drug, which is convenient for the subsequent collection of drug powder and avoids the waste of drugs. After the drug is crushed, the nurse can rotate the rotating frame 4 so that the drug powder inside the abrasive cylinder 5 is driven synchronously until the abrasive cylinder 5 corresponds to the opening below the fixed cylinder 3. At this time, the drug falls out from here and the nurse can collect it. During this process, the motor 27 can be started to make the knocking rod 8 shake quickly, so that the abrasive cylinder 5 vibrates, which is convenient for the collection of drug powder. There is no need for the nurse to manually tap, which further avoids drug waste and is convenient for the nurse to use.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
