[0026] 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.
[0027] like Figure 1 , 2, 3, 4, 5, and 6 show an embodiment of a drug crushing and feeding device for neonates provided by the present invention, which comprises a main shell 1 of a size that is convenient for an operator to hold with one hand, a crushing chamber 2 for placing and processing tablets is arranged in the main shell 1, one side of the crushing chamber 2 is open, and a cover body 3 is detachably arranged at the opening to close or open the crushing chamber 2; a resistance module 4 and a crushing module 5 are respectively arranged on opposite sides of the crushing chamber 2, the resistance module 4 comprises a resistance member 41 and an excitation member 42, the excitation member 42 is arranged at the rear of the resistance member 41, the resistance member 41 is located in the crushing chamber 2, the excitation member 42 passes out from the main shell 1 to the outside for the operator to operate, and when the operator presses the excitation member 42 from the outside, the resistance member 41 is driven to approach the opposite side. The crushing module 5 comprises a grinding plate 51 and a sliding block 52. The grinding plate 51 is located in the crushing chamber 2 and can move left and right relative to the resistance member 41. The sliding block 52 is linked with the grinding plate 51, and the sliding block 52 passes out from the main shell 1 to the outside for the operator to operate. When the operator pushes the sliding block 52 from the outside to slide back and forth, the grinding plate 51 is simultaneously driven to reciprocate in the crushing chamber 2. When in use, the tablets are placed in the crushing chamber 2 and covered with the cover body 3. The operator holds the main shell 1 with one hand and presses the excitation member 42 with the fingers on one side to make the resistance member 41 press the tablet against the grinding plate 51 on the opposite side. The fingers on the other side push the sliding block 52 to slide back and forth, thereby driving the grinding plate 51 to reciprocate to grind and crush the tablets.
[0028] The present invention is implemented as follows Figure 1 , 2 As shown in 6, the main shell 1 is set to a size that can be held by an adult's palm. The doctor (doctor or nurse) holds the main shell 1 with one hand, places the tablet A to be crushed into the crushing chamber 2, and then covers the cover 3 to close the crushing chamber 2, thereby forming a closed environment that is not in contact with the outside world, making the entire grinding and crushing process cleaner and more hygienic. When holding the main shell 1, the doctor adjusts the trigger member 42 to a position where a finger D other than the thumb C can press, and the sliding block 52 corresponds to the thumb C. The trigger member 42 is pressed by a finger D to make the resistance member 41 push the tablet against the grinding plate 51 on the opposite side, and then the thumb C pushes the sliding block 52 to slide back and forth, thereby driving the grinding plate 51 to do reciprocating motion to grind and crush the tablet A. The entire process of pressing the trigger member 42 can be achieved by the doctor holding the main shell 1 tightly, which is relatively easy; and the thumb C, as the most flexible finger, can operate the sliding block 52 while the other four fingers cooperate with the palm to stabilize the main shell 1. After the tablet A is crushed, the doctor opens the cover 3 to pour out the crushed powder, which can be brewed and dissolved for feeding to the newborn; the remaining uncrushed medicine A can be limited by the doctor operating the resistance member 41 when pouring out the powder, so that the medicine A will not be poured out.
[0029] Preferably, the cover 3 is made of a transparent material. The doctor can then visually observe the pulverization of the drug A while pulverizing the drug A. The doctor can stop grinding and take out the powder when the pulverized drug powder is sufficient based on experience. The drug A is then stored separately for the next pulverization and administration.
[0030] As a preference, a flexible pad B (such as Figure 5 As shown), when the doctor holds the main shell 1, the pad B can better fit the palm and cooperate with each finger to better hold the device.
[0031] As an improved specific implementation method, the cover body 3 includes a base plate 31 and an annular inner wall 32, the annular inner wall 32 is placed on the base plate 31, and a circle of external threads is arranged on the outer side of the annular inner wall 32, and the inner side of the annular inner wall 32 and the base plate 31 form a transfer chamber 33 for holding ground medicinal powder; the opening of the crushing chamber 2 extends outward to form an annular outer wall 21, and the inner diameter of the annular outer wall 21 is larger than the inner diameter of the opening to form a step 22, and a circle of internal threads is arranged on the inner side of the annular outer wall 21, and when the cover body 3 is installed with the main shell 1, the external threads and internal threads of the annular inner wall 32 and the annular outer wall 21 are screwed together and locked, the annular inner wall 32 abuts against the step 22, and the transfer chamber 33 corresponds to the space of the crushing chamber 2.
[0032] like Figure 3 As shown, the cover 3 is configured to have a transfer cavity 33. After the pulverization is completed, the device can be turned over so that the cover 3 faces downward, and the powder falls into the transfer cavity 33 of the cover 3. The doctor can shake or pat the main shell 1 to make the powder fall fully into the transfer cavity 33 to prevent some powder from sticking to the drug A and not falling easily. Figure 1 , 2 As shown, due to the different structural designs, directions and modes of activities of the conflict module 4 and the crushing module 5, the crushing chamber 2 is not a traditional cylindrical space; in order for the powder to fully fall to the cover body 3 for transfer, the transfer chamber 33 still relies on the structure of the bottom plate 31 and the annular inner wall 32 to form a cylindrical space, and the outer and inner threads of the annular inner wall 32 and the annular outer wall 21 are screwed together, so that the cover body 3 and the main shell 1 form a good structural installation and locking, and the opening size of the transfer chamber 33 on the cover body 3 is larger than the crushing chamber 2, and the annular inner wall 32 is against the step 22, forming a barrier around the opening of the crushing chamber 2, so that when the powder is turned over to the transfer chamber 33, the powder can fall from the crushing chamber 2 to the transfer chamber 33. Preferably, a rubber ring can be added to the screwing position of the annular inner wall 32 or the annular outer wall 21 to improve the sealing performance.
[0033] As an improved specific embodiment, it also includes a sub-shell 6, in which a mixing chamber 61 for placing and brewing medicine powder is arranged. The mixing chamber 61 has an upper medicine inlet 62 and a lower side medicine outlet 63. The mixing chamber 61 is made of a transparent material and is provided with a scale 64. The medicine outlet 63 is detachably provided with a plug body 60 for closing or opening. The medicine inlet 62 and the cover body 3 are detachably installed to be closed or opened. The medicine inlet 62 is provided with a sub-mounting wall 65, and a circle of internal threads is arranged on the inner side of the sub-mounting wall 65. When the cover body 3 and the sub-shell 6 are installed, the external threads and internal threads of the annular inner wall 32 and the sub-mounting wall 65 are screwed together and locked, and the transfer chamber 33 corresponds to the mixing chamber 61 in space.
[0034] like Figure 4 As shown, the auxiliary housing 6 is provided to further provide the function of brewing medicine after the medicine powder is transferred by the transfer chamber 33. The medicine powder transferred by the transfer chamber 33 can be poured into the mixing chamber 61, which is provided with a scale 64. A sufficient amount of water can be poured in advance, and then the medicine powder is poured in. The outer and inner threads of the annular inner wall 32 and the auxiliary mounting wall 65 are screwed together, so that the cover body 3 and the auxiliary housing 6 form a good structural installation and locking. As a preferred embodiment, a rubber ring can be added to the screwing position of the annular inner wall 32 or the auxiliary mounting wall 65 to improve the sealing performance. The medicine powder can be dissolved by fully shaking the auxiliary housing 6, and then the plug 60 of the medicine outlet 63 can be removed to pour out the medicine, or the medicine can be sucked by inserting it into the tube, and then the medicine can be fed to the newborn through the tube.
[0035] As an improved specific implementation, the abutment member 41 is a horizontally arranged flexible sheet, and the trigger member 42 includes push posts 421 arranged at the rear of both sides of the flexible sheet, connecting rods 422 connected to the rear ends of the push posts 421 on both sides, and push rods 423 connected to the rear of the connecting rods 422; the push posts 421 and the push rods 423 are both axially movable and arranged in the slide holes 11 of their respective main housings 1, and a return spring 424 is sleeved on the push posts 421, and the return springs 424 respectively abut against the main housing 1 The inner wall 12 and the connecting rod 422 are structurally limited, the inner end of the push column 421 penetrates into the crushing chamber 2 and is connected to the flexible sheet, and the outer end of the push rod 423 penetrates out of the main shell 1 for the operator to operate; when the operator presses the push rod 423, the flexible sheet presses the tablet against the grinding plate 51 on the opposite side, the flexible sheet deforms to limit the surface of the tablet, and the reset spring 424 is compressed by the connecting rod 422 to store force; when the operator releases the pressure, the reset spring 424 drives the excitation member 42 to reset.
[0036] like Figure 1 , 2 As shown, in the specific implementation, the flexible sheet can better adapt to the shape of the tablet A and prevent the displacement of the tablet A during the continuous resistance process; the flexible sheet can be made of plastic, rubber or other medically deformable materials as needed. Figure 2In the state, the cross-section of tablet A is circular. When the flexible sheet is pressed against tablet A, the push pins 421 on both sides will be further pushed forward by the doctor's thrust, thereby causing the flexible sheet to bend forward and deform, thereby increasing the contact area between the flexible sheet and tablet A. This can provide better stability for the interference limit of tablet A, and tablet A is not prone to left-right displacement when being ground by the left-right reciprocating motion of the grinding plate 51.
[0037] Secondly, if the tablets to be processed are tablets with more special shapes, or tablets that have been ground before, their shapes will be diverse. In this case, when the flexible sheet contacts such tablets, it can fit according to their shapes, and then find a stable position during the active grinding of the grinding plate 51 to form a stable contact state, thereby ensuring orderly grinding and crushing of the tablets.
[0038] On the third aspect, when the tablet is nearly ground, the flexible sheet can rely on its easily deformable property to adhere to the shape of the grinding plate 51 and resist to stabilize the tablet.
[0039] The movement of the flexible sheet is realized by the excitation member 42 connected at the rear, specifically the push posts 421 on both sides, which provide structural strength on both sides of the flexible sheet, and after the middle of the flexible sheet contacts the tablet, the push posts 421 on both sides continue to move to provide the flexible sheet deformation and the matching state of the limiting tablet. The push posts 421 on both sides are connected by a connecting rod 422 and are synchronously driven by a push rod 423 at the rear, and the symmetrical structure provides stability for the movement. The flexible sheet can store force when it contacts the tablet through the setting of a reset spring 424. After the doctor releases the force, the reset spring 424 can reset the flexible sheet and keep the structure in an orderly reset state, which is convenient for pouring out the powder or taking out the tablets. The crushing chamber 2 maintains the maximum space state when not in use, which is convenient for putting in the tablets. In addition, Figure 1 , 2 The structure and size shown are one embodiment of the resistance member 41 and the excitation member 42. According to the different sizes of the tablets to be crushed and the different degrees of crushing, the length and width specifications of the resistance member 41, the feed amount of the excitation member 42, the elastic force of the return spring 424 and other parameters can be further flexibly designed to achieve the desired drug processing effect.
[0040] As an improved specific implementation method, an outer arc-shaped slide groove 13 and an inner arc-shaped slide groove 14 are provided on the main shell 1, and the sliding block 52 can be slidably set in the outer arc-shaped slide groove 13, and the outer side of the sliding block 52 is exposed from the outer side of the main shell 1 for the operator to operate, and the grinding plate 51 can be slidably set in the inner arc-shaped slide groove 14, and the inner side of the grinding plate 51 is located in the crushing chamber 2 to grind the tablets.
[0041] like Figure 1 , 2As shown, by means of the setting of the outer arc-shaped slide groove 13 and the inner arc-shaped slide groove 14, an arc-shaped sliding track is provided for the sliding block 52 and the grinding plate 51, thereby realizing the arc-shaped reciprocating motion trajectory of the two. Through the reciprocating motion under the arc-shaped trajectory, the doctor can push the sliding block 52 back and forth, and the grinding plate 51 can reciprocate in the grinding chamber 2 to realize tablet grinding.
[0042] As an improved specific implementation method, an arcuate inner rack 521 is arranged on the inner side of the sliding block 52, an arcuate outer rack 511 is arranged on the outer side of the grinding plate 51, and a transmission gear 15 is also rotatably arranged in the main shell 1. The arcuate inner rack 521, the transmission gear 15, and the arcuate outer rack 511 are meshed in sequence for transmission.
[0043] like Figure 1 , 2 As shown, the sliding block 52 and the grinding plate 51 are partially adapted to the shapes of the outer arc groove 13 and the inner arc groove 14 to realize arc sliding. The arc inner rack 521 and the arc outer rack 511 are further arranged by relying on the arc structure of the two. The racks are arranged by relying on the transmission gear 15 to realize a stable meshing transmission structure, which can effectively convert the reciprocating motion of the sliding block 52 into the reciprocating motion of the grinding plate 51.
[0044] As an improved specific implementation, the sliding block 52 includes a first arc-shaped sliding block 522 and a push block 523 which are connected to each other. The first arc-shaped sliding block 522 is located in the outer arc-shaped sliding groove 13 for sliding, and the push block 523 is located outside the main shell 1 for the operator to operate.
[0045] like Figure 1 , 2 As shown, the first arc-shaped slider 522 is designed to be an arc-shaped structure that is fully compatible with the outer arc-shaped slide groove 13. The two cooperate to achieve a stable and smooth sliding state. The first arc-shaped slider 522 and the push block 523 can be connected by a connecting block. The push block 523 extends to the outside of the main housing 1, and the connecting block slides in the hole structure opened on the main housing 1; the reciprocating limit position of the first arc-shaped slider 522 and the push block 523 can be limited by the depth of the two sides of the outer arc-shaped slide groove 13 matching the two sides of the first arc-shaped slider 522 to reach the conflict, or by the left and right limit position conflict of the connecting block when the hole structure slides. During reciprocating activity, the push block 523 can be designed to completely cover the hole structure, thereby preventing foreign matter from falling into the hole structure.
[0046] As an improved specific implementation, the grinding plate 51 includes a second arc-shaped slider 512 and a tooth plate 513 connected to each other, the second arc-shaped slider 512 is located in the inner arc-shaped slide groove 14 for sliding, and the tooth plate 513 is located in the grinding chamber 2 for grinding the tablets, and the inner surface of the tooth plate 513 has continuous grinding teeth.
[0047] like Figure 1 , 2 As shown, the second arc-shaped slider 512 is designed to be an arc-shaped structure that is fully compatible with the inner arc-shaped slide groove 14. The two cooperate to achieve a stable and smooth sliding state. The second arc-shaped slider 512 and the tooth plate 513 can be connected by a connecting block. The tooth plate 513 extends into the crushing chamber 2, and the connecting block slides in the hole structure opened on the main shell 1; the reciprocating limit position of the second arc-shaped slider 512 and the tooth plate 513 can be limited by the depth of the two sides of the inner arc-shaped slide groove 14 and the two sides of the second arc-shaped slider 512 reaching the conflict, or by the left and right limit position conflict of the connecting block when the hole structure slides, or by the conflict position of the two sides of the crushing chamber 2 when the tooth plate 513 slides. When reciprocating, the tooth plate 513 can be designed to completely cover the hole structure, so as to prevent the powder from falling into the hole structure. As an optimization, the teeth of the tooth plate 513 can be set in a variety of specifications, for example, as a basic classification, they can be divided into coarse teeth, medium teeth, and fine teeth. The doctor can disassemble the upper cover plate corresponding to the grinding plate 51 of the main shell 1 and replace it according to actual needs, so as to control the fineness of the grinding of the tablets to meet different needs. Figure 1 , 2 The inner tooth surface of the tooth plate 513 shown is set to an arc shape, so as to perform smooth grinding and crushing in the reciprocating arc motion. According to special needs, its inner tooth surface can also be set to a specific shape such as a flat surface, a wavy surface, etc., to achieve grinding and crushing effects of different degrees of fineness.
[0048] As an improved specific implementation method, a plurality of transmission gears 15 are provided, and the plurality of transmission gears 15 are meshingly arranged in the main shell 1 and transmit the arcuate inner rack 521 and the arcuate outer rack 511, and the plurality of transmission gears 15 extend the transmission space so that the arrangement position of the sliding block 52 and the arrangement position of the grinding plate 51 are offset, so that the sliding block 52 and the excitation member 42 form an arrangement angle relative to the center of the main shell 1.
[0049] like Figure 1 , 2 As shown in FIG. 6 , through the sequential meshing transmission of multiple transmission gears 15, the arrangement position of the sliding block 52 meshed with the multiple transmission gears 15 and the arrangement position of the grinding plate 51 are extended, so that the arrangement positions of the two are offset. The most practical effect is that the original excitation member 42, that is, the push rod 423 and the grinding plate 51 are on the same axis, and the offset sliding block 52 leaves the axis, so that it forms an angle with the excitation member 42. Figure 6After the angle is formed, the sliding block 52 and the triggering member 42 are in a position that is more convenient for human hand holding and operation, that is, the doctor can press the triggering member 42 with one hand, such as the ring finger, and the thumb C is just at the position of the sliding block 52, which can facilitate the sliding operation of the sliding block 52; the arrangement method of forming an angle can be operated by both the left and right hands, and only needs to be held on different sides of the main shell 1. Whether it is operated by the left or right hand, the palm can be supported by the aforementioned pad B or the cover 3 on the opposite side.
[0050] The above are only preferred embodiments of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
