Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dispensing equipment, in particular to a needle medicine self-feeding device and an automatic needle medicine extraction equipment. BACKGROUND

[0002] The preparation of needle medicine is an indispensable link in medicine production, hospital pharmacy and clinical treatment. The traditional dispensing equipment has many shortcomings in the process of dispensing and liquid extraction of medicine bottles, especially in the automatic processing of medicine bottles. At present, most of the dispensing equipment mainly relies on manual operation in the process of dispensing medicine bottles. The operator needs to manually put the medicine bottles into the dispensing machine one by one. This way not only is inefficient, but also can cause the medicine bottles to be placed inaccurately due to human factors, thereby affecting the subsequent liquid extraction and preparation process. In addition, manual dispensing also increases the frequency of contact between the operator and the medicine bottles, which may adversely affect the hygiene of the medicine bottles.

[0003] In order to solve the problem of low efficiency of manual dispensing, some dispensing equipment uses a jig module to place multiple medicine bottles before putting them into the dispensing machine for liquid extraction. However, this jig module placement method also has obvious defects. First, the use of jig modules increases the complexity and cost of the equipment, and additional devices are needed to achieve the placement and fixation of the medicine bottles. Second, the medicine bottles placed by the jig module often need to be accurately positioned and adjusted when put into the dispensing machine, otherwise the medicine bottles may be jammed or cannot enter the next process correctly. In addition, the use of jig modules also limits the types and sizes of medicine bottles. Different specifications of medicine bottles may need different jig modules to adapt, which further increases the use cost and operation complexity of the equipment.

[0004] For example, the hospital ampoule dispensing machine disclosed in the Chinese utility model patent with publication number CN221797014U realizes the innovative technology of cutting the neck of the ampoule bottle and breaking the head of the ampoule bottle, and has compact structure and small space occupation. However, in this scheme, the turntable assembly is used to clamp and convey the ampoule bottle to the subsequent station for breaking and liquid extraction. The dispensing process of the ampoule bottle still needs to be manually dispensed by the operator. For example, the dispensing device disclosed in the Chinese utility model patent with publication number CN222517314U and the intelligent preparation device for tumor chemotherapy medicine disclosed in the Chinese invention patent with publication number CN119771228A also need to use manual means to put different specifications of medicine bottles into the fixed slots on the rotating disc, and then the liquid extraction can be carried out.

[0005] The automatic dispensing system disclosed by the Chinese utility model patent with the publication number CN222828829U is provided with a medicine bottle warehouse for storing medicine bottles, but the unloading of the medicine bottles and the transfer between different components need to rely on the transfer and action of the mechanical arm, the precision requirement and the equipment cost are relatively high, and the operation steps and the debugging process are troublesome. The intravenous liquid dispensing robot disclosed by the Chinese invention patent with the publication number CN112263479A utilizes multi-batch medicine jigs and automatic processing to realize efficient and accurate liquid dispensing and a safe working environment. However, in the scheme, whether it is the ampoule bottle medicine application assembly or the medicine feeder assembly and the powder medicine application assembly, the jigs module form is used for medicine application, and the corresponding medicine bottle positions are placed and fixed by using the module form to facilitate subsequent processing actions. The placement of the medicine bottles on the jig module also needs to rely on manual or conventional mechanical equipment simulating manual operation, which also increases the labor cost or the use cost.

[0006] Secondly, the existing equipment has poor adaptability when cutting the bottle opening. The hospital ampoule medicine dispensing machine disclosed by the Chinese utility model patent with the publication number CN221797014U has a fixed knife wheel position, and the cutting of medicine bottles of different specifications can only be adaptively adjusted by relying on the movement of the attached base, so the adaptability is poor. When breaking the bottle opening after cutting, the existing hospital ampoule medicine dispensing machine disclosed by the Chinese invention patent with the publication number CN105329827A and the Chinese utility model patent with the publication number CN221797014U both use a single movable breaking lever or an L-shaped breaking seat to move and push the bottle opening, and there is no subsequent operation and processing for the pushed bottle opening part, which is left to fall naturally, which is not conducive to collection and has a probability of causing fragments at the breaking point to fall into the bottle.

[0007] In summary, the existing dispensing equipment has low manual operation efficiency, complex module placement operation, high cost, poor applicability and other problems in the medicine bottle unloading and liquid extraction link, which seriously affects the automation degree and overall performance of the dispensing equipment, and urgently needs to be solved through technical innovation.

Detailed Implementation

[0061] 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.

[0062] like Figure 1 , 2 As shown in Embodiment 1, a self-feeding device for injectable drugs includes a support 1, a lower housing 2 fixedly mounted on the support 1, a feeding channel 3 on the lower housing 2, and a vial release assembly 4 on the side wall of the feeding channel 3. The vial release assembly 4 is driven by a drive mechanism 5 fixedly mounted inside the lower housing 2. Driven by the drive mechanism 5, the vial release assembly 4 can release vials entering the feeding channel 3 one by one, allowing the vials to exit one by one from the feeding channel 3. A vial compartment 6 is detachably mounted on the lower housing 2, and the outlet of the vial compartment 6 corresponds to the feeding channel 3, allowing vials to enter the feeding channel 3 from the vial compartment 6. The feeding channel 3 provides a guiding channel for the movement and feeding of vials. The vial compartment 6 is used to hold vials. In this embodiment, the vial compartment 6 is open, making it easy to observe the number of vials in the vial compartment 6 and to add vials into the vial compartment 6. The medicine bottle compartment 6 has an opening on one side corresponding to the feeding channel 3. Medicine bottles are placed in the medicine bottle compartment 6 in an arranged and stacked manner. The medicine bottle compartment 6 is set at an angle, so that the medicine bottles arranged and stacked in the medicine bottle compartment 6 can slide down the bottom surface of the inclined medicine bottle compartment 6 under the action of gravity, enter the feeding channel 3 through the opening on one side of the medicine bottle compartment 6, and slide down through the feeding channel 3 to achieve automatic feeding.

[0063] Embodiment 2, a self-supply device for injection medicine, based on embodiment 1, as shown in Figure 2 The arc-shaped flow guide surface 62 and the guide inclined surface 63 are respectively arranged on the two sides of the opening of the medicine bottle bin 6, and are used to guide the medicine bottles to smoothly enter the lower flow channel 3 from the medicine bottle bin 6. In this embodiment, the arc-shaped flow guide surface 62 and the guide inclined surface 63 are asymmetrically arranged on the two sides of the lower flow direction of the medicine bottle bin 6, thereby playing a guiding role when the medicine bottles slide along the inclined inner wall of the medicine bottle bin 6, facilitating the movement of the medicine bottles, avoiding the accumulation of the medicine bottles at the opening of the medicine bottle bin 6, causing the problem of poor feeding.

[0064] In addition, in this embodiment, as shown in Figure 2 , 3 The lower shell 2 includes a triangular base body 21 fixedly connected to the support 1 by bolts, and the triangular base body 21 is provided with a receiving shell 22 on the inclined surface thereof, and the lower flow channel 3 is formed in the receiving shell 22, and the receiving shell 22 is provided with a flared mouth 23 for cooperating with the medicine bottle bin 6. The bottom plate of the medicine bottle bin 6 is attached to the inclined surface of the triangular base body 21, and the outer walls of the positions where the arc-shaped flow guide surface 62 and the guide inclined surface 63 of the medicine bottle bin 6 are located correspond to the two side walls of the flared mouth 23, respectively, and the flared mouth 23 and the inclined surface of the triangular base body 21 jointly bear the medicine bottle bin 6 filled with medicine bottles. The lower flow channel 3 includes a U-shaped flow channel part 31 cooperating with the flared mouth 23, the U-shaped flow channel part 31 is in communication with a lower flow pipe 32 arranged on the lower side of the inclined surface of the triangular base body 21, and the lower flow pipe 32 is vertically arranged or inclined, which is beneficial to the feeding.

[0065] As a further specific embodiment, as shown in Figure 2 , 3As shown in FIG. 4, the medicine bottle releasing assembly 4 comprises a blocking plate 41 and a pushing plate 42 which are horizontally slidably arranged on the lower shell 2 and connected with the driving mechanism 5. The lower shell 2 is provided with openings corresponding to the blocking plate 41 and the pushing plate 42. The blocking plate 41 and the pushing plate 42 can be driven by the driving mechanism 5 to reciprocally slide in the lower flow channel 3. In this embodiment, the blocking plate 41 is horizontally arranged between the trumpet mouth 23 and the U-shaped flow channel 31 and can be used to close or open the communication between the trumpet mouth 23 and the U-shaped flow channel 31. The pushing plate 42 is horizontally arranged at the middle connecting part of the U-shaped flow channel 31. Further, the pushing plate 42 is provided with a receiving groove I 43 for accommodating a single medicine bottle. The medicine bottles entering the U-shaped flow channel 31 are sequentially slid into the receiving groove I 43. When the pushing plate 42 moves horizontally, the medicine bottles in the receiving groove I 43 are moved horizontally to the other side of the U-shaped flow channel 31. The other side of the U-shaped flow channel 31 is provided with an opening which is in communication with the lower flow pipe 32. When the medicine bottles are pushed by the pushing plate 42 to the other side of the U-shaped flow channel 31, the medicine bottles automatically slide downward, twist and fall into the lower flow pipe 32 under the action of gravity. The structure of the other side of the U-shaped flow channel 31 provides a space for the twisted medicine bottles to fall. When the pushing plate 42 moves horizontally, the pushing plate 42 itself closes the one side of the U-shaped flow channel 31 to prevent other medicine bottles from falling, thereby realizing the sequential feeding.

[0066] In addition, the lower shell 2 is provided with a positioning pin I 24 and the medicine bottle bin 6 is provided with a locking hole for the positioning pin I 24. When the medicine bottle bin 6 needs to be replaced, the positioning pin I 24 and the locking hole are used to lock or release the position of the medicine bottle bin 6.

[0067] As an optional solution, the upper cover of the medicine bottle bin 6 is provided with an opening. The medicine bottles can be directly and manually put into the medicine bottle bin 6 in batches without removing the medicine bottle bin 6. Figure 7 As shown in FIG. 6, the arc-shaped flow guide surface 62 is separately arranged on the additional shell 65. The additional shell 65 is provided with a plug-in column 66 and the receiving shell 22 is provided with a through hole for the plug-in column 66. In actual use, the additional shell 65 is attached to the medicine bottle bin 6 and the guide inclined surface 63 is located on both sides of the opening of the medicine bottle bin 6. Then, the plug-in column 66 is inserted into the through hole of the receiving shell 22 to realize stable connection. Finally, the position of the medicine bottle bin 6 is locked by the positioning pin I 24. In this embodiment, different sizes of the additional shell 65 are provided to meet the smooth feeding of different sizes of medicine bottles. When different sizes of medicine bottles need to be accommodated, the additional shell 65 of different sizes is replaced to meet the feeding and guiding requirements of different sizes of medicine bottles.

[0068] As a further optional implementation, as shown in Figure 6 The upper end of the feeding pipe 32 is a conical pipe body 321, and the lower end of the conical pipe body 321 is a circular pipe 322. The conical pipe body 321 can guide the medicine bottle falling into it, and the circular pipe 322 can limit the falling path and posture of the medicine bottle to some extent, so that the medicine bottle can fall in a centered and vertical posture. In this embodiment, the upper end of the conical pipe body 321 is hingedly arranged on one side below the inclined surface of the triangular base 21, so that the feeding pipe 32 can be folded as a whole to provide space for convenient debugging and maintenance. The triangular base 21 is provided with a positioning pin II 323 matched with the other side of the upper end of the conical pipe body 321, and the positioning pin II 323 is used to lock the position of the feeding pipe 32.

[0087] Embodiment 6, a kind of automatic extraction equipment of injection medicine, different from embodiment 5, as the second optional cutting member 104 floating arrangement scheme, as shown in Figure 16 、 17As shown in FIGS. 18, in the embodiment, the opening and closing end of the second opening and closing cylinder 103 is provided with a floating support mechanism 106, and the floating support mechanism 106 is connected with the cutting member 104. The floating support mechanism 106 comprises a floating block 1061, and the opening and closing end of the second opening and closing cylinder 103 is provided with a support shell 1062, and the floating block 1061 is movably arranged in the support shell 1062. The support shell 1062 provides a support connection basis for the floating block 1061. The spring II 1063 is arranged between the outer side of the floating block 1061 and the support shell 1062. The floating block 1061 can move horizontally relative to the opening and closing direction of the second opening and closing cylinder 103, so that the floating block 1061 has floating capability in the horizontal direction. In addition, the floating block 1061 is provided with a knife seat 1064 which can slide vertically, and the cutting member 104 is arranged at the lower end of the knife seat 1064. The knife seat 1064 is slidably connected with the floating block 1061, so as to realize floating support of the cutting member 104 in the vertical direction. The cutting member 104 can be adaptively matched with the bottle neck in the vertical direction and the horizontal direction.

[0088] Specifically, in the embodiment, the floating block 1061 is provided with a protruding block 1068 on both sides, and the support shell 1062 is horizontally and symmetrically provided with a sliding groove matched with the protruding block 1068, so as to realize sliding guidance of the floating block 1061. The floating block 1061 is provided with a through hole, and the knife seat 1064 is arranged in the through hole. The both ends of the knife seat 1064 are threadedly connected with anti-dropping caps 1067, so as to prevent the knife seat 1064 from being dropped out of the through hole when sliding vertically. The cutting member 104 is fixed at the lower end of the knife seat 1064 through the anti-dropping caps 1067. Thus, the knife seat 1064 is slid in the through hole to realize floating in the vertical direction. In addition, a flat cutting surface 1069 is arranged between the knife seat 1064 and the through hole, so as to realize rotation limitation through cooperation of the flat cutting surface 1069 between the two, to avoid relative rotation between the knife seat 1064 and the through hole, and to avoid rotation of the cutting member 104, thereby affecting the cutting effect.

When the cutting member 104 contacts the bottle neck, the floating block 1061 can float in the horizontal direction, and the spring II 1063 can buffer the floating block 1061 in the radial direction, so as to avoid the pre-tightening force being too large to cause the cutting member 104 to directly press on the bottle neck and cause the medicine bottle to break, and the pre-tightening force exerted on the cutting member 104 can maintain the cutting contact force between the cutting member 104 and the bottle neck. In addition, due to the floating connection form of the knife seat 1064 which can slide vertically, the cutting member 104 can move along the arc of the bottle neck to the place where the radius of the bottle neck is the smallest when it fits the bottle neck, so as to better fit the outer wall of the bottle neck, limit the cutting route, maintain stable cutting, adapt to bottle necks of different specifications and shapes, improve the cutting effect and adaptability, and effectively solve the poor adaptability of the existing device.

When it is necessary to adjust the elasticity of the spring II 1063, the knob I 1065 is rotated, the end of the knob I 1065 moves along the axis of the knob I 1065, so as to compress or relax the spring II 1063, thereby changing the pre-tightening force of the spring II 1063 on the floating block 1061, and adjusting the cutting force of the cutting member 104 connected with the floating block 1061 contacting the bottle neck. Further, in order to prevent the pre-tightening force from changing due to loosening of the knob I 1065 after long-term use after adjustment, a check screw 1066 is arranged on the support shell 1062 and cooperates with the knob I 1065, and the end of the check screw 1066 abuts against the knob I 1065, so as to limit the position of the knob I 1065 after adjustment.
