Description

Technical Field

[0001] This utility model relates to the field of automatic liquid dispensing equipment technology, and in particular to a liquid bag hanger. Background Technology

[0002] The hospital's drug preparation process involves drawing the liquid (such as sodium chloride solution) from the infusion bag into a syringe, injecting the liquid from the syringe into a vial, shaking it to fully mix the liquid and powder in the vial, and then drawing the mixed liquid back into the infusion bag through the syringe.

[0003] Currently, the transportation of infusion bags that have not been prepared for medication in hospitals is mainly done manually by medical staff. Since the demand for intravenous medications in various departments of the hospital is relatively large, manual handling not only consumes a lot of manpower and resources for the hospital, but also increases the risk of harm to the health of nursing staff and contamination of medications. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing drug preparation methods involve manual handling of unprepared infusion bags, which is labor-intensive and resource-intensive, and poses risks to personnel health and drug contamination. This invention provides a bag holder that enables rapid filling and transportation of unprepared infusion bags, reducing drug contamination and the risk to personnel health, and contributing to improved efficiency in automated operations.

[0005] To solve the above-mentioned technical problems, this utility model discloses a liquid bag hanger, comprising: a hanger body extending along a first direction, the hanger body being used to support the liquid tube of the liquid bag; a clamping assembly connected to the hanger body in a movable manner along the first direction, the clamping assembly including a first clamping member and a second clamping member, along a second direction, the first clamping member and the second clamping member being able to move relative to each other along the second direction, the first direction intersecting the second direction; a push-pull portion connected to the clamping assembly; and a direction switching portion disposed on the hanger body, the direction switching portion being connected to the push-pull portion and the clamping assembly respectively, the push-pull portion being able to move forward along the first direction under the action of an external force, through the direction switching portion. The clamping assembly can be switched from a first motion state to a second motion state, or the push-pull part can move in the opposite direction along the first direction under the action of an external force, and the clamping assembly can be switched from the second motion state to the first motion state through the direction switching part; in the first motion state, along the second direction, there is a first distance between the first clamping member and the second clamping member, and the first clamping member and the second clamping member together define a clamping space for clamping the liquid tube of the liquid bag; in the second motion state, along the second direction, there is a second distance between the first clamping member and the second clamping member, and the first clamping member and the second clamping member do not clamp the liquid tube of the liquid bag, and the first distance is less than the second distance.

[0006] By adopting the above technical solution, the liquid bag hanger of this application embodiment can apply an external force (e.g., a push-pull force) along the first direction to the push-pull part, so that the push-pull part drives the clamping assembly to drive the first clamping member and the second clamping member to move in the forward or reverse direction along the first direction.

[0007] For example, when the push-pull unit drives the clamping assembly in the first motion state to move forward in the first direction, the first and second clamping members form a clamping space for the liquid tube of the liquid bag. This means the first and second clamping members of the clamping assembly can clamp and drive the liquid tube of the liquid bag within the clamping space to move forward in the first direction along with the push-pull unit. Furthermore, the liquid tubes of the liquid bags are all supported by the hanger body. When the first and second clamping members of the clamping assembly clamp and drive the liquid tube of the liquid bag to move forward in the first direction, the liquid tube slides along the hanger body, providing reliable accommodating space and support for the liquid tube of the liquid bag, accommodating the parallel mounting of multiple liquid bags. This allows the liquid bag clamped by the first and second clamping members to be removed from one end of the hanger body, facilitating the transport of the removed liquid bag in subsequent processes.

[0008] Alternatively, when the push-pull section drives the clamping assembly in the second motion state to move in the opposite direction in the first direction, the first and second clamping members do not clamp the liquid tube of the liquid bag. This allows the first and second clamping members to reset to the other end of the hanger body, facilitating the placement of a new liquid bag into the hanger body in subsequent processes.

[0009] Furthermore, the liquid bag holder of this application embodiment can switch the movement state of the clamping assembly through the direction switching part, change the movement direction of the first clamping member and the second clamping member, so that the first clamping member and the second clamping member move in opposite directions along the second direction, that is, the distance between the first clamping member and the second clamping member increases (for example, increases to the second distance), the first clamping member and the second clamping member open outwards, and do not clamp the liquid tube of the liquid bag, and the clamping assembly switches from the first movement state to the second movement state;

[0010] Alternatively, the first clamping member and the second clamping member may move toward each other in a second direction, that is, the distance between the first clamping member and the second clamping member is reduced (for example, reduced to a first distance), the first clamping member and the second clamping member clamp inward to clamp the liquid tube of the liquid bag, and the clamping assembly switches from the second movement state to the first movement state.

[0011] Therefore, compared with the existing drug preparation methods that involve manual handling of infusion bags without liquid preparation, the liquid bag rack of this application embodiment, on the one hand, through optimized structural design, allows the operator to hang multiple liquid bags on the rack with only simple pushing and pulling actions; on the other hand, the liquid bag rack of this application embodiment is easy to operate and highly automated. It can automatically hang and pick up liquid bags on the rack with only simple interaction with automated equipment such as robotic arms, without the need for manual operation. It can achieve fast and reliable clamping and release of liquid bags, saving labor costs, improving the efficiency of automated operation, and avoiding drug contamination and harm to personnel health.

[0012] For example, the number of liquid bags hanging on the liquid bag rack is not limited in the embodiments of this application. For example, the number of liquid bags hanging on the liquid bag rack can be one, two, three, four, five, six, seven, eight, nine, ten, fifteen or more.

That is, the annular flange 221 of one side of the liquid tube 220 of the liquid bag 200 is supported by the first support portion 111a, and the annular flange 221 of the other side of the liquid tube 220 is supported by the second support portion 111b, so that the liquid tubes 220 of the ten liquid bags 200 can be supported by the first support portion 111a and the second support portion 111b of the hanger body 110.

[0066] For example, both the first support portion 111a and the second support portion 111b are sheet-like structures, but are not limited thereto. The embodiments of this application do not specifically limit the structure of the first support portion 111a and the second support portion 111b, as long as they can form a receiving space 111c for hanging the liquid bag 200.

[0067] For example, the first direction X (i.e., the length direction of the bracket body 110) is perpendicular to the second direction Y (i.e., the width direction of the bracket body 110), the first direction X is perpendicular to the third direction Z (i.e., the height direction of the bracket body 110), and the third direction Z is perpendicular to the second direction Y. It should be noted that the mutual perpendicularity in this application is not absolute. Approximate perpendicularity due to processing and assembly errors (e.g., an angle of 89.9° between two structural features) is also within the scope of mutual perpendicularity in this application. The definition of mutual perpendicularity will not be repeated below.

[0068] For example, continue to refer to Figure 1 The liquid bag hanger 100 of this application embodiment has two clamping components 120 and a push-pull portion 130. Along the first direction X, the two clamping components 120 are spaced apart on the hanger body 110 to simultaneously clamp the liquid tubes 220 of multiple liquid bags 200, significantly improving the hanging capacity and hanging efficiency of the liquid bag hanger 100. However, this application is not limited to this. It is understood that the more clamping components 120 there are, the more liquid bags 200 the liquid bag hanger 100 can clamp, which further improves operational efficiency. For example, in other possible embodiments, the number of clamping components 120 in this application embodiment can be one, three, four, five, six, or more.

[0069] For ease of explanation, the following description uses one of the two clamping components 120 as an example.

[0070] like Figure 1 As shown, the clamping assembly 120 and the push-pull part 130 are both connected to the hanger body 110 in a movable manner along the first direction X, and the push-pull part 130 is connected to the clamping assembly 120, so that the push-pull part 130 can drive the clamping assembly 120 to move relative to the hanger body 110 in the first direction X in the forward or reverse direction under the action of an external force (such as a push-pull force).

[0071] Specifically, refer to Figure 3 and combined Figure 2The clamping assembly 120 of this application embodiment includes a clamping body 121, a first clamping member 122, and a second clamping member 123. The clamping body 121 is connected to the hanger body 110 in a movable manner along a first direction X. The first clamping member 122 and the second clamping member 123 are both connected to the clamping body 121 in a movable manner along a second direction Y. The push-pull part 130 is connected to the clamping body 121, so that the push-pull part 130 can drive the clamping body 121 to move in the forward or reverse direction of the first direction X under the action of an external force (such as a push-pull force).

[0072] For example, such as Figure 2 and Figure 3 As shown, the first clamping member 122 of this application embodiment includes a first transmission part 122a and a first clamping part 122b, and the second clamping member 123 includes a second transmission part 123a and a second clamping part 123b. The first transmission part 122a and the second transmission part 123a are located on opposite sides of the clamping body 121 along the second direction Y, and both the first transmission part 122a and the second transmission part 123a are connected to the clamping body 121 in a movably movable manner along the second direction Y.

[0073] Along a third direction (such as) Figure 2 (As shown in the Z direction), the first clamping part 122b is connected to the lower end of the first transmission part 122a, and the second clamping part 123b is connected to the lower end of the second transmission part 123a. Both the first clamping part 122b and the second clamping part 123b extend along the first direction X.

[0074] Furthermore, along the second direction Y, the first clamping part 122b and the second clamping part 123b are arranged opposite to each other, so that the first clamping part 122b and the second clamping part 123b can respectively follow the first transmission part 122a and the second transmission part 123a to move towards each other relative to the clamping body 121 along the second direction Y to define a clamping space 120a. The clamping space 120a is used to accommodate the liquid tube 220 of the liquid bag 200 to clamp the liquid tube 220. At this time, the clamping assembly 120 is in a first motion state, and along the second direction Y, there is a first distance W1 between the first clamping part 122b and the second clamping part 123b (see...). Figure 2 ).

[0075] Alternatively, the first clamping part 122b and the second clamping part 123b can respectively follow the first transmission part 122a and the second transmission part 123a to move away from the clamping body 121 along the second direction Y. At this time, there is a second distance W2 between the first clamping part 122b and the second clamping part 123b along the second direction Y, where W2 is greater than W1. Then the clamping assembly 120 is in a second movement state, and the first clamping part 122b and the second clamping part 123b do not clamp the liquid tube 220 of the liquid bag 200.

[0076] For example, the distance between the first clamping portion 122b and the second clamping portion 123b described in the embodiments of this application refers to the distance between the portion of the first clamping portion 122b that does not have the first arc-shaped recess 122f and the corresponding portion of the second clamping portion 123b that does not have the second arc-shaped recess 123f along the second direction Y.

[0077] Therefore, the liquid bag hanger 100 of this application embodiment can apply an external force (e.g., a push-pull force) along the first direction X to the push-pull portion 130, so that the push-pull portion 130 drives the clamping body 121 of the clamping assembly 120 to drive the first clamping member 122 and the second clamping member 123 to move in the forward or reverse direction of the first direction.

[0078] For example, the push-pull portion 130 drives the clamping assembly 120, which is in a first motion state, along a first direction in the positive direction (e.g.) Figure 4A When moving (as shown in the X1 direction), since the first clamping part 122b and the second clamping part 123b form a clamping space 120a that can clamp the liquid tube 220 of the liquid bag 200, the first clamping part 122b and the second clamping part 123b of the clamping assembly 120 can clamp and drive the liquid tube 220 of the liquid bag 200 in the clamping space 120a to move along the first direction X1 with the push-pull part 130.

[0079] Furthermore, since the liquid tubes 220 of the liquid bags 200 hanging on the liquid bag hanger 100 are all supported by the first support portion 111a and the second support portion 111b, the first clamping portion 122b and the second clamping portion 123b can jointly clamp the liquid tubes 220 so that they can slide relative to the first support portion 111a and the second support portion 111b in the first direction X1, so that the liquid tubes 220 of the liquid bags 200 clamped by the first clamping portion 122b and the second clamping portion 123b can extend out from the end of the hanger body 110 (for example, the end 1101 near the suction portion 132 of the push-pull portion 130).

[0080] This results in the liquid bag 200 (see first clamping part 122b and second clamping part 123b) being clamped. Figure 1 The target liquid bag 200a) can be removed from one end 1101 of the hanger body 110, so that the removed liquid bag 200 can be transported in subsequent processes.

[0081] Alternatively, the clamping assembly 120, which is in a second motion state, is driven by the push-pull section 130 to reverse in the first direction (e.g., Figure 4A When moving (as shown in the X2 direction), the first clamping part 122b and the second clamping part 123b do not clamp the liquid tube 220 of the liquid bag 200.

[0082] Furthermore, since the liquid tubes 220 of the liquid bag 200 are both supported by the first support portion 111a and the second support portion 111b, the first clamping portion 122b and the second clamping portion 123b can move in the opposite direction X2 relative to the first support portion 111a, the second support portion 111b and the liquid bag 200 supported by them.

[0083] This allows the first clamping part 122b and the second clamping part 123b to be reset to the other end 1102 of the hanger body 110, making it easier to put the new liquid bag 200 into the hanger body 110 in subsequent processes.

[0084] Continue to refer to Figure 3 and combined Figure 1 For example, the hanger body 110 of this application embodiment has four support portions 112, which are spaced apart along the first direction X. Each pair of adjacent support portions 112 corresponds to one of the aforementioned clamping components 120, and each pair of adjacent support portions 112 is provided with a direction switching portion 140 corresponding to the clamping component 120. That is, the two direction switching portions 140 of this application embodiment correspond to the two clamping components 120. For ease of explanation, the following description uses one of the two direction switching portions 140 as an example.

[0085] Specifically, such as Figure 1 As shown, the direction switching part 140 is threadedly connected to the outer shell 110a of the hanger body 110 and is mounted between the two support parts 112 along the first direction X. Along the third direction Z, the direction switching part 140 is located above the clamping assembly 120 and is connected to the first clamping part 122b and the second clamping part 123b, so that when the clamping assembly 120 moves along the first direction X1 following the push-pull part 130, the clamping assembly 120 can switch from the first movement state to the second movement state.

[0086] Alternatively, when the clamping assembly 120 moves in the opposite direction X2 along the first direction following the push-pull part 130, the clamping assembly 120 switches from the second motion state to the first motion state.

[0087] Therefore, the liquid bag holder 100 of this application embodiment can switch the movement state of the clamping assembly 120 through the direction switching part 140, change the movement direction of the first clamping part 122b and the second clamping part 123b, so that the first clamping part 122b and the second clamping part 123b move in opposite directions along the second direction Y, that is, the distance between the first clamping part 122b and the second clamping part 123b increases (for example, increases to the second distance W2), the first clamping part 122b and the second clamping part 123b open outwards and do not clamp the liquid tube 220 of the liquid bag 200, and the clamping assembly 120 switches from the first movement state to the second movement state;

[0088] Alternatively, the first clamping part 122b and the second clamping part 123b may move toward each other along the second direction Y, that is, the distance between the first clamping part 122b and the second clamping part 123b may be reduced (for example, reduced to a first distance W1), the first clamping part 122b and the second clamping part 123b may clamp inward to clamp the liquid tube 220 of the liquid bag 200, and the clamping assembly 120 may switch from the second movement state to the first movement state.

[0089] In summary, compared with the existing drug preparation methods that involve manual handling of infusion bags without liquid preparation, the liquid bag hanger 100 of this application embodiment, on the one hand, through optimized structural design, allows the operator to hang multiple liquid bags 200 on the liquid bag hanger 100 with only simple pushing and pulling actions; on the other hand, it can automatically hang and pick up the liquid bags 200 on the liquid bag hanger 100 with only simple interaction with automated equipment such as robotic arms, without the need for manual operation by the operator, saving labor costs, improving the efficiency of automated operation, and avoiding drug contamination and harm to personnel health.

[0090] For example, such as Figure 2 As shown, the hanger body 110 of this embodiment further includes a partition 113, which extends along a first direction X and is connected to four support portions 112 respectively. Along a second direction Y, the partition 113 is located between the first clamping member 122 and the second clamping member 123, that is, the partition 113 extends along a third direction Z into the clamping space 120a formed between the first clamping portion 122b and the second clamping portion 123b, to avoid mutual interference between the two liquid tubes 220 of the liquid bag 200 and improve operational clarity.

[0091] For example, such as Figure 3As shown, in this embodiment of the application, the push-pull portion 130 extends along the first direction X. Along the first direction X, one end of the push-pull portion 130 is provided with a push-pull handle 131, and the other end of the push-pull portion 130 is provided with a suction portion 132 adapted to the magnetic suction assembly (not shown in the figure). For example, in other possible embodiments, a robotic arm with a magnetic suction component is connected to a robotic arm. The robotic arm can drive the robotic arm to move until the magnetic suction component engages with the suction portion 132 of the push-pull portion 130. The robotic arm drives the robotic arm to actuate the push-pull portion 130, applying external force to it. This causes the clamping component 120, which is in the first motion state, to move along the first direction X1 with the push-pull portion 130, causing the first clamping portion 122b and the second clamping portion 123b to clamp a liquid bag 200 (e.g., a target liquid bag 200a) and move it out of the hanger body 110 along the first direction X. Then, the direction switching portion 140 switches the clamping component 120 to the second motion state, causing the first clamping portion 122b and the second clamping portion 123b to open outward. Thus, the robotic arm can drive the robotic arm to grasp the target liquid bag 200a, thereby removing a liquid bag near the robotic arm from the liquid bag hanger 100.

[0092] The specific structure of the liquid bag hanger 100 according to the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0093] For ease of explanation, the following description uses a clamping component 120 and a corresponding direction switching part 140 as an example.

[0094] refer to Figure 4A The direction switching part 140 of this application embodiment includes a substrate 141. The substrate 141 is provided with a first groove 142 and a second groove 143. The first groove 142 corresponds to the first clamping member 122, and the second groove 143 corresponds to the second clamping member 123.

[0095] Specifically, such as Figures 4A to 5B As shown, the substrate 141 has a first end face 141a and a second end face 141b, and a first groove 142 and a second groove 143 are both provided on the first end face 141a. The bottom wall 142a of the first groove 142 is provided with a first limiting member 144, which is spaced apart from the side wall 142b of the first groove 142. A first annular groove 145 is formed between the side wall 144a of the first limiting member 144 and the side wall 142b of the first groove 142. A first clamping member 122 is connected to the first annular groove 145 and can move along the first annular groove 145.

[0096] The bottom wall 143a of the second groove 143 is provided with a second limiting member 146. The second limiting member 146 is spaced apart from the side wall 143b of the second groove 143, and a second annular groove 147 is formed between the side wall 146a of the second limiting member 146 and the side wall 143b of the second groove 143. The second clamping member 123 is connected to the second annular groove 147, and the second clamping member 123 can move along the second annular groove 147.

[0097] Continue to refer to Figure 4A and combined Figure 6 The direction switching unit 140 in this embodiment further includes a first linkage member 148 and a second linkage member 149. One end 1481 of the first linkage member 148 is rotatably connected to the substrate 141, and one end 1491 of the second linkage member 149 is rotatably connected to the substrate 141.

[0098] Furthermore, the first linkage 148 is connected to the first clamping member 122 and the push-pull portion 130 respectively, and the second linkage 149 is connected to the second clamping member 123 and the push-pull portion 130 respectively. The push-pull portion 130 can drive the first linkage 148 and the second linkage 149 relative to the substrate 141 along a fourth direction (e.g., ...). Figure 4A (As shown in the R direction) rotate in the forward or reverse direction to drive the first clamping member 122 to move along the first annular groove 145 and the second clamping member 123 to move along the second annular groove 147, so that the clamping assembly 120 switches between the first movement state and the second movement state.

[0099] For example, such as Figure 4A As shown, the first linkage 148 has a strip-shaped first through hole 148a and a strip-shaped second through hole 148b. The first clamping member 122 has a first protrusion 122c. Along the third direction Z, the first protrusion 122c passes through the first through hole 148a and extends into the first annular groove 145, so that the first protrusion 122c is slidably connected with the first through hole 148a and the first annular groove 145 respectively. Furthermore, the push-pull part 130 has a second protrusion 130a. Along the third direction Z, the second protrusion 130a extends into the second through hole 148b and is slidably connected with the second through hole 148b. Thus, the push-pull part 130 can move in the first direction X in either the forward or reverse direction under the action of an external force, so as to drive the second protrusion 130a to slide along the second through hole 148b and drive the first protrusion 122c to slide along the first annular groove 145.

[0100] Furthermore, the second linkage member 149 has a strip-shaped third through hole 149a and a strip-shaped fourth through hole 149b. The second clamping member 123 has a third protrusion 123c. Along the third direction Z, the third protrusion 123c passes through the third through hole 149a and extends into the second annular groove 147, so that the third protrusion 123c is slidably connected with the third through hole 149a and the second annular groove 147 respectively. Additionally, the push-pull part 130 has a fourth protrusion 130b. Along the second direction Y, the fourth protrusion 130b is spaced apart from the second protrusion 130a. Along the third direction Z, the fourth protrusion 130b extends into the fourth through hole 149b and is slidably connected with the fourth through hole 149b. Thus, the push-pull part 130 can move along the first direction X in a positive or negative direction under the action of external force, driving the fourth protrusion 130b to slide along the fourth through hole 149b and causing the third protrusion 123c to slide along the second annular groove 147.

[0101] For example, such as Figure 4A As shown, the liquid bag hanger in this embodiment of the application further includes a hinge post 150. One end 1481 of the first linkage member 148 has a first hinge hole (not shown in the figure), and one end 1491 of the second linkage member 149 has a second hinge hole (not shown in the figure). Along the third direction Z, the hinge post 150 passes through the first hinge hole and the second hinge hole in sequence and is fixed to the substrate 141, so that the first linkage member 148 and the second linkage member 149 are hinged to the substrate 141 together through the hinge post 150, and can rotate relative to the hinge post 150 in the fourth direction R or the positive direction.

[0102] Thus, the movement of the push-pull part 130 is transmitted synchronously to the first linkage 148 and the second linkage 149 through the sliding engagement of the second protrusion 130a with the second through hole 148b of the first linkage 148 and the sliding engagement of the fourth protrusion 130b with the third through hole 149a of the second linkage 149. The movement is also transmitted synchronously to the first clamping member 122 and the second clamping member 123 through the engagement of the first through hole 148a with the first protrusion 122c and the sliding engagement of the third through hole 149a with the third protrusion 123c. This achieves efficient conversion of movement and transmission of force, resulting in a simple structure and sensitive response.

[0103] Exemplary, the embodiments of this application do not specifically limit the structure of the first linkage 148 and the second linkage 149. In the above embodiments, the first through hole 148a, the second through hole 148b, the third through hole 149a, and the fourth through hole 149b are all strip-shaped holes, providing a travel distance for linkage. The extending directions of the first through hole 148a and the second through hole 148b (e.g., Figure 4A As shown in the E1 direction, the extension directions of the third through hole 149a and the fourth through hole 149b are parallel to each other (as shown in the E1 direction). Figure 4AAs shown in the E2 direction, the two through holes are parallel to each other, and along the first direction X, the second through hole 148b is located on the side of the first through hole 148a near the push-pull part 130, and the fourth through hole 149b is located on the side of the third through hole 149a near the push-pull part 130, which can accommodate the movement conversion between the first clamping member 122 and the second clamping member 123 in different directions.

[0104] However, it is not limited to this. For example, the first through hole 148a, the second through hole 148b, the third through hole 149a and the fourth through hole 149b can also be polygonal holes, etc. Alternatively, in other possible embodiments, the first clamping member 122 and the second clamping member 123 may have through holes, and the corresponding first linkage member 148 and the second linkage member 149 may have protrusions that are adapted to the through holes.

[0105] For example, such as Figures 4A to 4D As shown, the included angle α between the first linkage 148 and the second linkage 149 ranges from 0° to 180°, including 0° and 180°. For example, the included angle α is 30°, 45°, 60°, 90°, 120° or 150°, etc.

[0106] For example, such as Figure 5A As shown, the first annular groove 145 and the second annular groove 147 each include a first guide groove 145a, a second guide groove 145b, a third guide groove 145c and a fourth guide groove 145d that are interconnected.

[0107] Specifically, the first guide groove 145a and the third guide groove 145c both extend along the first direction X, and the second guide groove 145b and the fourth guide groove 145d both extend along the second direction Y. Along the second direction Y, the first guide groove 145a and the third guide groove 145c are spaced apart, and along the first direction X, the second guide groove 145b and the fourth guide groove 145d are spaced apart. That is, both the first annular groove 145 and the second annular groove 147 are U-shaped grooves.

[0108] Therefore, as Figure 5A and combined Figure 4A and Figure 4B As shown, when the push-pull part 130 moves along the first direction X1 so that the second protrusion 130a drives the first protrusion 122c to slide along the first guide groove 145a, the clamping assembly 120 is in the first motion state.

[0109] Alternatively, when the push-pull portion 130 moves in the first direction X1 and the fourth protrusion 130b drives the third protrusion 123c to slide along the first guide groove 145a, the clamping assembly 120 is in the first motion state.

[0110] like Figure 5A and combined Figure 4B and Figure 4CAs shown, when the push-pull portion 130 moves along the first direction X1 to cause the second protrusion 130a to drive the first protrusion 122c to slide along the second guide groove 145b, the clamping assembly 120 is in the second motion state.

[0111] Alternatively, when the push-pull portion 130 moves in the first direction X1 and the fourth protrusion 130b drives the third protrusion 123c to slide along the second guide groove 145b, the clamping assembly 120 is in the second motion state.

[0112] like Figure 5A and combined Figure 4C and Figure 4D As shown, when the push-pull part 130 moves in the opposite direction X2 in the first direction so that the second protrusion 130a drives the first protrusion 122c to slide along the third guide groove 145c, the clamping assembly 120 is in the second motion state.

[0113] Alternatively, when the push-pull portion 130 moves in the opposite direction X2 in the first direction, and the fourth protrusion 130b drives the third protrusion 123c to slide along the third guide groove 145c, the clamping assembly 120 is in the second motion state.

[0114] like Figure 5A and combined Figure 4D As shown, when the push-pull part 130 moves in the opposite direction X2 in the first direction so that the second protrusion 130a drives the first protrusion 122c to slide along the fourth guide groove 145d, the clamping assembly 120 is in the second motion state.

[0115] Alternatively, when the push-pull portion 130 moves in the opposite direction X2 in the first direction, and the fourth protrusion 130b drives the third protrusion 123c to slide along the fourth guide groove 145d, the clamping assembly 120 is in the second movement state. Thus, the liquid bag holder 100 of this embodiment can reliably guide the first protrusion 122c and the third protrusion 123c to slide along the first and second annular grooves 145 and 147 respectively, through the first annular groove 145 and the second annular groove 147 with a U-shaped groove, thereby achieving precise switching of the movement direction of the first clamping member 122 and the second clamping member 123 and positioning of the first clamping member 122 and the second clamping member 123, i.e., the first protrusion 122c and the third protrusion 123c. c slides and cycles through the first annular groove 145 and the second annular groove 147 respectively. Through the guiding effect of the annular closed structure of the first annular groove 145 and the second annular groove 147, the first clamping member 122 and the second clamping member 123 of this application embodiment realize continuous cyclic movement between the first direction X and the second direction Y. This structural design effectively improves the movement efficiency and space utilization of the first clamping member 122 and the second clamping member 123, while ensuring the accuracy and reliability of the movement trajectory of the first clamping member 122 and the second clamping member 123.

[0116] Furthermore, driven by the push-pull part 130, the first clamping member 122 and the second clamping member 123 of this application embodiment can respectively follow the annular loop structure of the first annular groove 145 and the second annular groove 147, and jointly clamp the liquid bag 200 and slide relative to the first support part 111a and the second support part 111b in the first direction forward X1 until they open; or the first clamping member 122 and the second clamping member 123 can open and move in the first direction reverse X2 until they are clamped, realizing the cyclic switching of the clamping assembly 120 between the first movement state and the second movement state.

[0117] The embodiments of this application do not specifically limit the structure of the first groove 142 and the second groove 143, as long as the clamping component 120 can switch between the first movement state and the second movement state. For example, in other possible embodiments, the first groove 142 and the second groove 143 can also be polygonal, circular or other shaped slide rails. Correspondingly, the embodiments of this application do not specifically limit the structure of the first protrusion 122c and the third protrusion 123c. For example, the first protrusion 122c and the third protrusion 123c can also be sliders adapted to the slide rails described above.

[0118] refer to Figure 5B and combined Figure 5A In this embodiment of the application, the first guide groove 145a is provided with a first one-way guide part 1451, and the fourth guide groove 145d is provided with a second one-way guide part 1452.

[0119] The first one-way guide portion 1451 is connected to the first guide groove 145a in a movable manner along the second direction Y. The first one-way guide portion 1451 is used to guide the first protrusion 122c or the third protrusion 123c into the second guide groove 145b, and to prevent the first protrusion 122c or the third protrusion 123c from entering the first guide groove 145a from the second guide groove 145b. The second one-way guide portion 1452 is connected to the fourth guide groove 145d in a movable manner along the first direction X. The second one-way guide portion 1452 is used to guide the first protrusion 122c or the third protrusion 123c into the first guide groove 145a, and to prevent the first protrusion 122c or the third protrusion 123c from entering the fourth guide groove 145d from the first guide groove 145a.

[0120] Therefore, in this embodiment of the application, the first unidirectional guide 1451 reliably guides the first protrusion 122c or the third protrusion 123c to move along the first direction X, and after the first unidirectional guide 1451 passes the first unidirectional guide 1451, it blocks the first protrusion 122c or the third protrusion 123c from continuing to move along the first direction X, ensuring that the first protrusion 122c or the third protrusion 123c smoothly disengages from the first guide groove 145a and enters the second guide groove 145b, reducing jamming and improving the reliability and service life of the direction switching part 140.

[0121] Furthermore, in this embodiment, the first protrusion 122c or the third protrusion 123c is reliably guided to move along the second direction Y by the second one-way guide part 1452, and after the first protrusion 122c or the third protrusion 123c passes through the second one-way guide part 1452, the first protrusion 122c or the third protrusion 123c is blocked from continuing to move along the second direction Y, ensuring that the first protrusion 122c or the third protrusion 123c smoothly disengages from the second guide groove 145b and enters the first guide groove 145a, reducing jamming and improving the reliability and service life of the direction switching part 140.

[0122] refer to Figure 5A and Figure 5B In this embodiment, the first one-way guide portion 1451 includes a first blocking portion 1451a and a first elastic reset member 1451b, and the second one-way guide portion 1452 includes a second blocking portion 1452a and a second elastic reset member 1452b. Exemplarily, the first blocking portion 1451a and the second blocking portion 1452a are sliders, and the first elastic reset member 1451b and the second elastic reset member 1452b are springs.

[0123] Specifically, such as Figure 5A and Figure 5B As shown, the second end face 141b of the substrate 141 is provided with a first fixing groove 1411, a second fixing groove 1412 and a third fixing groove 1413. The first fixing groove 1411 corresponds to the first blocking part 1451a.

[0124] The first blocking part 1451a is provided in the first guide groove 145a and is connected to the first guide groove 145a in a movable manner along the second direction Y. Along the first direction X, the first blocking part 1451a has a first guide slope 1451c on the side facing the first protrusion 122c. The first guide slope 1451c is used to guide the first protrusion 122c or the third protrusion 123c to move along the first direction X. The first blocking part 1451a has a first blocking surface 1451d on the side facing away from the push-pull part 130. The first blocking surface 1451d is used to prevent the first protrusion 122c or the third protrusion 123c from entering the first guide groove 145a from the second guide groove 145b.

[0125] In other words, during the movement of the first protrusion 122c along the first guide groove 145a, when the first protrusion 122c moves to abut against the first guide slope 1451c of the first blocking part 1451a, the first protrusion 122c can continue to move along the first guide groove 145a along the first guide slope 1451c and squeeze the first blocking part 1451a to make the first blocking part 1451a retract along the second direction Y.

[0126] Furthermore, since the first elastic reset member 1451b is elastically connected to the first blocking portion 1451a, the first elastic reset member 1451b can apply an elastic force to the first blocking portion 1451a, causing the first blocking portion 1451a to move along the second direction Y toward the first guide groove 145a. That is, when the first guide slope 1451c of the first blocking portion 1451a is not subjected to pressure from the first protrusion 122c, the first blocking portion 1451a can extend into the first guide groove 145a along the second direction Y under the action of the elastic force of the first elastic reset member 1451b.

[0127] Therefore, as Figure 5A As shown, when the first protrusion 122c extends outward in the first guide groove 145a along the first direction (e.g.) Figure 5A When moving (as shown in the X1 direction), the first protrusion 122c can press the first guide slope 1451c of the first blocking part 1451a, causing the first blocking part 1451a to retract along the second direction Y, and continue to pass through the first blocking part 1451a outward along the first direction X1 under the drive of the push-pull part 130; at this time, when the first clamping member 122 (or the second clamping member 123) continues to be driven by the push-pull part 130, the first blocking part 1451a extends into the first guide groove due to the pressure applied by the first blocking part 1451a without being squeezed. Within 145a, the first blocking surface 1451d blocks the first protrusion 122c (or the third protrusion 123c) from returning to the first guide groove 145a. The first protrusion 122c continues to move under the drive of the push-pull part 130 and enters the second guide groove 145b. That is, the movement direction of the first clamping member 122 (or the second clamping member 123) changes from moving along the first direction X to moving along the second direction Y, so that the first clamping member 122 and the second clamping member 123 open along the second direction Y, and the clamping assembly 120 switches from the first movement state to the second movement state.

[0128] For example, along the first direction X, the distance D1 between the first blocking surface 1451d of the first blocking portion 1451a and the side wall of the first guide groove 145a and the distance D2 between the two side walls of the second guide groove 145b are equal.

[0129] For example, such as Figure 5BAs shown, the first fixing groove 1411 extends along the second direction Y, and along the second direction Y, the two ends of the first fixing groove 1411 are respectively connected to two adjacent first guide grooves 145a in the first groove 142 and the second groove 143. The first elastic reset member 1451b and the two first blocking parts 1451a are both accommodated in the first fixing groove 1411, and the first elastic reset member 1451b is disposed between the two first blocking parts 1451a so that the two first blocking parts 1451a are elastically connected along the second direction Y.

[0130] Similarly, as Figure 5A As shown, the second blocking part 1452a is disposed in the second guide groove 145b and is connected to the second guide groove 145b in a movable manner along the first direction X. Along the second direction Y, the second blocking part 1452a has a second guide slope 1452c on the side facing the first protrusion 122c. The second guide slope 1452c is used to guide the first protrusion 122c or the third protrusion 123c to move along the second direction Y. The second blocking part 1452a has a second blocking surface 1452d on the side facing away from the third guide groove 145c. The second blocking surface 1452d is used to prevent the first protrusion 122c or the third protrusion 123c from entering the fourth guide groove 145d from the first guide groove 145a.

[0131] In other words, during the movement of the first protrusion 122c (or the third protrusion 123c) along the fourth guide groove 145d, when the first protrusion 122c moves to abut against the second guide slope 1452c of the second blocking part 1452a, the first protrusion 122c can continue to move along the fourth guide groove 145d along the second guide slope 1452c and squeeze the second blocking part 1452a to make the second blocking part 1452a retract along the first direction X.

[0132] Furthermore, since the second elastic reset member 1452b is elastically connected to the second blocking portion 1452a, the second elastic reset member 1452b can apply an elastic force to the second blocking portion 1452a, causing the second blocking portion 1452a to move along the first direction X toward the fourth guide groove 145d. That is, when the second guide slope 1452c of the second blocking portion 1452a is not subjected to pressure from the first protrusion 122c, the second blocking portion 1452a can extend into the fourth guide groove 145d along the first direction X under the action of the elastic force of the second elastic reset member 1452b.

[0133] Therefore, as Figure 5A As shown, when the first protrusion 122c moves inward along the second direction in the fourth guide groove 145d (as shown in the figure), Figure 5AWhen moving (as shown in the Y1 direction), the first protrusion 122c can squeeze the second guide slope 1452c of the second blocking part 1452a, causing the second blocking part 1452a to retract along the first direction X, and continue to pass through the second blocking part 1452a inward along the second direction Y1 under the drive of the push-pull part 130; at this time, when the first clamping member 122 (or the second clamping member 123) continues to be driven outward along the first direction X1 by the push-pull part 130, since the second blocking part 1452a is not squeezed The pressure applied by the pressure causes the second blocking part 1452a to extend into the fourth guide groove 145d. The first protrusion 122c continues to move under the drive of the push-pull part 130 and enters the first guide groove 145a. That is, the movement direction of the first clamping member 122 (or the second clamping member 123) changes from moving along the second direction Y to moving along the first direction X, so that the first clamping member 122 and the second clamping member 123 move outward along the first direction X, and the clamping assembly 120 switches from the second movement state to the first movement state.

[0134] For example, along the second direction Y, the distance D3 between the second blocking surface 1452d of the second blocking portion 1452a and the side wall of the second guide groove 145b is equal to the distance D4 between the two side walls of the first guide groove 145a.

[0135] For example, such as Figure 5B As shown, the second fixing groove 1412 and the third fixing groove 1413 are connected to the two fourth guide grooves 145d in a one-to-one correspondence. Both the second fixing groove 1412 and the third fixing groove 1413 extend along the first direction X, and both the second fixing groove 1412 and the third fixing groove 1413 accommodate a second blocking part 1452a and a second elastic reset member 1452b. The second elastic reset member 1452b is disposed at the second blocking part 1452a and the second fixing groove 1412 along the second direction Y. Between the side wall 1412a of the second blocking portion 1452a and the side wall 1412a of the second fixing groove 1412, so that the second blocking portion 1452a and the side wall 1412a of the second fixing groove 1412 are elastically connected along the first direction X; and between the side wall 1413a of the second blocking portion 1452a and the side wall 1413a of the third fixing groove 1413, so that the second blocking portion 1452a and the side wall 1413a of the third fixing groove 1413 are elastically connected along the first direction X.

[0136] The specific structure of the blocking part is not limited in the embodiments of this application. In the above embodiments, the first blocking part 1451a is slidably connected to the corresponding first guide groove 145a and the first fixing groove 1411, and the second blocking part 1452a is slidably connected to the corresponding second guide groove 145b, the second fixing groove 1412 and the third fixing groove 1413. However, it is not limited to this. For example, the first blocking part 1451a and the corresponding first guide groove 145a and the first fixing groove 1411 can also be connected by a lead screw or by a slider and a guide rail working together.

[0137] Furthermore, the orientation of the guide slope of the blocking part is not limited in the embodiments of this application. In the above embodiments, the first guide slope 1451c of the two first blocking parts 1451a is disposed opposite to the suction part 132 of the push-pull part 130 along the first direction X, and the second guide slope 1452c of the two second blocking parts 1452a is disposed opposite to each other along the second direction Y. However, it is not limited to this. For example, the first guide slope 1451c of the two first blocking parts 1451a is disposed opposite to the suction part 132 of the push-pull part 130 along the first direction X, and the second guide slope 1452c of the two second blocking parts 1452a is disposed opposite to each other along the second direction Y.

[0138] For example, such as Figure 5B As shown, the bottom walls of the first fixing groove 1411, the second fixing groove 1412, and the third fixing groove 1413 are all provided with bosses 1414. In this embodiment, by connecting the stop block 1415 to the bosses 1414, the first blocking part 1451a and the corresponding first elastic reset member 1451b are fixed in the first fixing groove 1411, and the two second blocking parts 1452a and the corresponding second elastic reset members 1452b are fixed in the second fixing groove 1412 and the third fixing groove 1413. The stop block 1415 is threadedly connected to the bosses 1414. However, this is not limited to this. In this embodiment, the fixing method of the blocking part and the elastic reset member is not limited. For example, in other possible embodiments, the blocking part and the elastic reset member can also be snapped into the corresponding groove.

[0139] refer to Figure 6 The clamping assembly 120 in this embodiment further includes a first optical axis 124 and a second optical axis 125. The clamping body 121 further includes a first bearing 121a, a second bearing 121b, a third optical axis 121c, and a fourth optical axis 121d. The first transmission part 122a includes a third bearing (not shown in the figure) adapted to the third optical axis 121c and a fourth bearing (not shown in the figure) adapted to the fourth optical axis 121d. The second transmission part 123a includes a fifth bearing (not shown in the figure) adapted to the third optical axis 121c and a sixth bearing (not shown in the figure) adapted to the fourth optical axis 121d.

[0140] Specifically, such as Figure 6 As shown, the first optical axis 124 and the second optical axis 125 are spaced apart along the second direction Y and are respectively connected to the first leg 112a and the second leg 112b of the support part 112 of the bracket body 110. The first optical axis 124 and the second optical axis 125 both extend along the first direction X. The first bearing 121a and the second bearing 121b correspond one-to-one with the first optical axis 124 and the second optical axis 125. That is, the first bearing 121a is sleeved on the first optical axis 124 and slidably connected to the first optical axis 124, and the second bearing 121b is sleeved on the second optical axis 125 and slidably connected to the second optical axis 125. Through the sliding cooperation between the bearing and the optical axis, the clamping body 121 moves smoothly and without deviation relative to the bracket body 110 along the first direction X, thereby enhancing the stability of the movement.

[0141] The third optical axis 121c and the fourth optical axis 121d are spaced apart along the first direction X on the clamping body 121, and both the third optical axis 121c and the fourth optical axis 121d extend along the second direction Y. The third and fourth bearings of the first transmission part 122a are respectively sleeved on the third optical axis 121c and the fourth optical axis 121d, and are slidably connected to the third optical axis 121c and the fourth optical axis 121d. The fifth and sixth bearings of the second transmission part 123a are respectively sleeved on the third optical axis 121c and the fourth optical axis 121d, and are slidably connected to the third optical axis 121c and the fourth optical axis 121d, so that the first transmission part 122a and the second transmission part 123a can slide along the third optical axis 121c and the fourth optical axis 121d through the sliding cooperation of the bearings and the optical axis, thereby realizing the flexible opening and closing of the first clamping member 122 and the second clamping member 123 in the second direction Y. And, exemplarily, as Figure 6 As shown, the first transmission part 122a and the second transmission part 123a are symmetrically arranged on opposite sides of the clamping body 121 along the second direction Y, making the clamping assembly 120 of this application embodiment compact in structure and reliable in movement.

[0142] The structure of the clamping component 120 is not limited in this application embodiment. It can be specifically set according to the actual situation, as long as the first clamping member 122 and the second clamping member 123 can be connected to the clamping body 121 in a movable manner along the second direction Y. In other possible implementations, for example, the first clamping member 122 and the second clamping member 123 can also be connected to the clamping body 121 by means of a slider and a slide rail.

[0143] For example, such as Figure 6As shown, the first clamping part 122b includes a plurality of first arc-shaped recesses 122f, and the second clamping part 123b includes a plurality of second arc-shaped recesses 123f. Along the first direction X, the plurality of first arc-shaped recesses 122f are spaced apart, and the plurality of second arc-shaped recesses 123f are spaced apart. Furthermore, along the second direction Y, each first arc-shaped recess 122f is positioned opposite to a corresponding second arc-shaped recess 123f, so that when the clamping assembly 120 is in the first moving state, each first arc-shaped recess 122f can form an elliptical clamping space 120a with the corresponding second arc-shaped recess 123f. Each elliptical clamping space 120a is used to clamp two liquid tubes 220 of a liquid bag 200. Along the second direction Y, a separating part 113 is provided between each first arc-shaped recess 122f and the corresponding second arc-shaped recess 123f to separate the two liquid tubes 220 in an elliptical clamping space 120a (see [reference]). Figure 2 This is to avoid mutual interference between the two liquid tubes 220 of the liquid bag 200 and improve the clarity of operation.

[0144] For example, such as Figure 6 As shown, the push-pull part 130 of this application embodiment has a fork 133, which includes a first end 133a and a second end 133b. Along the first direction X, the first end 133a and the second end 133b of the fork 133 are respectively connected to the first protrusion 122c of the first clamping member 122 and the third protrusion 123c of the second clamping member 123, so as to realize the balanced transmission of the push-pull action to the clamping body 121, ensuring that the operator operates the push-pull part 130 to drive the clamping body 121 to move along the first direction X with less effort and synchronous movement, thereby enhancing the movement stability of the clamping body 121.

[0145] like Figure 3 and Figure 4A As shown, the liquid bag holder 100 in this embodiment of the application also includes a positioning part 160. The substrate 141 has a limiting hole 1416 extending along the first direction X. Along the third direction Z, the positioning part 160 passes through the limiting hole 1416 and is connected to the fork piece 133. By cooperating with the limiting hole 1416 on the substrate 141, the positioning part 160 restricts the movement stroke of the push-pull part 130 along the first direction X, and at the same time prevents the push-pull part 130 from deflecting, thereby improving the stability of the push-pull operation.

[0146] For example, such as Figure 3As shown, the push-pull part 130 of this application embodiment also includes a connecting rod 134. Along the first direction X, the connecting rod 134 is located between the push-pull handle 131 and the suction part 132 and is connected to the positioning part 160 of one clamping component 120 and the fork 133 of the other clamping component 120, respectively. This allows for convenient manual operation via the push-pull handle 131, and with the cooperation of the suction part 132 and the magnetic suction component, the positioning part 160 and the fork 133 between the two clamping components 120 are connected via the connecting rod 134. In addition to meeting the requirement of setting multiple clamping components 120 to improve the hanging capacity and efficiency of the liquid bag hanger 100 of this application embodiment, it can also enhance the overall rigidity of the push-pull part 130 and facilitate the transmission of operating force, making operation more convenient and labor-saving.

[0147] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
