Description

Technical Field

[0001] This application relates to the technical field of medical devices, and in particular to a trolley and infusion slide rail. Background Technology

[0002] As an important component of medical equipment, infusion slides play a crucial role in medical settings such as wards, operating rooms, and infusion rooms. Infusion slides make infusion operations more convenient, allowing for flexible adjustment of the infusion position according to the patient's actual needs, and greatly improving the quality and efficiency of medical services.

[0003] Common infusion slides are U-shaped and installed close to the ceiling. When an infusion is needed, a trolley moves along the arc of the slide, moving the infusion rod at the bottom of the trolley to the appropriate position. Existing trolleys usually consist of pulleys and metal hooks. However, since the top of the infusion rod is also composed of hooks, the way the hooks at the top of the infusion rod are connected to the metal hooks on the trolley can easily detach during movement. This can not only interrupt the infusion process and affect the patient's treatment, but may also damage the infusion equipment, increasing medical risks and costs. Utility Model Content

[0004] To reduce the probability of the infusion push rod falling off the slide rail when moving, this application provides a trolley.

[0005] The present application provides a trolley with the following technical solution: it includes a lifting ring, a bracket and two sets of pulleys. The two sets of pulleys are symmetrically arranged on one side of the lifting ring. The side of the lifting ring away from the pulleys is used for the hook at the top of the infusion rod to be suspended. The pulleys are connected to the lifting ring through the bracket. The lifting ring and the bracket are integrally formed.

[0006] By adopting the above technical solutions, the design of the lifting ring reduces the probability of the infusion rod falling off the slide rail when moving, thereby reducing the risk of interruption during infusion, lowering medical costs, and improving the safety and efficiency of medical services. At the same time, the one-piece molded lifting ring and bracket not only reduce the number of assembly steps and parts, lowering production costs, but also avoids the problem of loose connections that may be caused by insecure assembly, making the overall structure of the trolley more stable.

[0007] Preferably, the bracket is a trapezoidal bracket, the short side of the trapezoidal bracket and the lifting ring are integrally formed, and two sets of pulleys are symmetrically arranged at both ends of the long side of the trapezoidal bracket. The pulleys are rotatably connected to the trapezoidal bracket through a connector.

[0008] By adopting the above technical solution, the trapezoidal bracket makes the installation of the pulley block more stable, and the trapezoidal structure can better withstand the force generated when the trolley moves on the track.

[0009] Preferably, the bracket consists of two arc-shaped connecting rods, which are symmetrically arranged on one side of the lifting ring. The two arc-shaped connecting rods correspond one-to-one with the two sets of pulleys. One end of the arc-shaped connecting rod is integrally formed with the lifting ring, and the other end of the arc-shaped connecting rod is connected to the pulleys through a connector.

[0010] By adopting the above technical solution, the distance between the two pulley groups is increased and there is no connection between the two pulley groups, which makes the trolley move more smoothly and flexibly, reduces the jamming caused by track bending, improves the convenience and efficiency of infusion operation, and at the same time reduces the probability of wear between the trolley and the track, extending the service life of the trolley and the track.

[0011] Preferably, the lifting ring includes a main lifting ring and an auxiliary lifting ring, the main lifting ring and the auxiliary lifting ring are closable and connected, and two sets of pulleys are symmetrically arranged on one side of the main lifting ring.

[0012] Since in practical applications, there is a possibility that some infusion poles may also have a hanging ring at the top, by adopting the above technical solution, the main hanging ring and the auxiliary hanging ring can be opened and closed, so that the trolley can be adapted to different infusion poles, which facilitates the hanging and removal of the hook at the top of the infusion pole and improves the utilization rate of the trolley of this application in medical settings.

[0013] Preferably, one end of the main lifting ring and the auxiliary lifting ring are hinged together, the other end of the main lifting ring is provided with a magnetic plate, and the other end of the auxiliary lifting ring is provided with an iron plate, the magnetic plate being used to attract the iron plate.

[0014] By adopting the above technical solution, in actual use, medical staff can easily open the auxiliary ring, put the hook or ring at the top of the infusion rod into the main ring, and then use the magnetic and iron plates to close the auxiliary ring, ensuring that the infusion rod is stably suspended on the ring.

[0015] Preferably, each group of pulleys includes two pulleys, each group of pulleys corresponds to one of the connecting members, the two pulleys of each group are respectively located at both ends of the connecting member, the connecting member passes through the pulleys to make the pulleys and the bracket rotatably connected, and the opposite end faces of the two pulleys of each group have a convex ring extending coaxially, the convex ring is embedded in the bracket and the convex ring and the bracket are rotatably connected.

[0016] By adopting the above technical solution, a stepped shape is formed between the pulley and the convex ring, which has a certain load-bearing capacity, improves the overall structural strength of the trolley, and further enables the trolley to move smoothly on the track.

[0017] Preferably, the connector includes a rivet and a rivet head, and a bushing extends from the bracket for the rivet to pass through. The rivet passes sequentially through one of the pulleys, the convex ring and the bushing in the same group, and the rivet head passes through another pulley and the convex ring in the same group and then is inserted and connected to the rivet.

[0018] By adopting the above technical solution, this connection method makes the rotation between the pulley and the bracket more flexible, while also ensuring the stability of the connection.

[0019] In addition, this application also provides an infusion slide rail.

[0020] The present application provides an infusion slide rail, which adopts the following technical solution: it includes a track body, which is used to guide and limit the sliding of the trolley as described above. The track body is provided with an infusion slide groove for the pulley group to be embedded. The infusion slide groove is opened around the circumference of the track body, and the support portion is embedded in the infusion slide groove.

[0021] By adopting the above technical solution and through the design of the infusion chute, a stable guiding and limiting function is provided for the infusion trolley, which can better cooperate with the use of the infusion trolley, allowing the trolley to move smoothly on the track, thereby improving the safety and efficiency of infusion operation.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. It reduces the probability of the infusion push rod falling off the slide rail when moving, thereby reducing the risk of interruption in the infusion process, lowering medical costs, and improving the safety and efficiency of medical services; 2. The one-piece molded lifting ring and bracket not only reduce the number of assembly steps and parts, thus lowering production costs, but also avoids loose connections that may result from insecure assembly, making the overall structure of the trolley more stable. 3. The increased spacing between the two pulley blocks and the absence of a connection between them make the trolley move more smoothly and flexibly, reducing jamming caused by track curvature and improving the convenience and efficiency of infusion operations.

Detailed Implementation

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] Example 1 refer to Figure 1 and Figure 2 This application discloses a trolley, including a hanging ring 110, a bracket, and two sets of pulleys. The two sets of pulleys are symmetrically arranged on one side of the hanging ring 110. The side of the hanging ring 110 away from the pulleys is used for suspending the hook at the top of the infusion rod. The pulleys are connected to the hanging ring 110 through the bracket. The hanging ring 110 and the bracket are integrally formed. The arrangement of the hanging ring 110 reduces the probability of the infusion rod falling off the slide rail when moving, reducing the risk of interruption during infusion, reducing medical costs, and improving the safety and efficiency of medical services. At the same time, the integrally formed hanging ring 110 and bracket not only reduce the number of assembly steps and parts, reducing production costs, but also avoid the problem of loose connection caused by weak assembly, making the overall structure of the trolley more stable.

[0027] Specifically, each pulley group includes two pulleys 140, and the support is a trapezoidal support 132. The short side of the trapezoidal support 132 and the lifting ring 110 are integrally formed. The two pulley groups are symmetrically arranged at both ends of the long side of the trapezoidal support 132 via connectors 120. There are two connectors 120, and each connector 120 corresponds to one pulley group. The connector 120 includes a rivet 121 and a rivet head 122. A bushing 133 for the rivet 121 to pass through extends from the trapezoidal support 132. Correspondingly, there are two bushings 133, and the axis of the bushings 133 is parallel to the axis of the lifting ring 110. The two pulleys 140 of each group are located at both ends of the bushing 133. A convex ring 141 extends coaxially from the end face of the trolley. The convex ring 141 is embedded in the bushing 133, and the convex ring 141 and the bushing 133 are rotatably connected. A step is formed between the pulley 140 and the convex ring 141, which has a certain load-bearing capacity and improves the overall structural strength of the trolley. At the same time, the rotatable connection between the convex ring 141 and the bushing 133 realizes the rotatable connection between the pulley 140 and the trapezoidal bracket 132. The rivet 121 passes through one pulley 140, the convex ring 141 and the bushing 133 in the same group in sequence. The rivet head 122 passes through another pulley 140 and the convex ring 141 in the same group and is inserted and connected to the rivet 121, so that the trolley can move smoothly on the track and also ensure the stability of the connection.

[0028] The implementation principle of this embodiment 1 is as follows: by designing the integrally formed lifting ring 110 and trapezoidal bracket 132, the production cost is reduced, the structural stability is improved, the probability of the infusion top rod falling off the slide rail when moving is reduced, the risk of interruption in the infusion process is reduced, medical costs are reduced, and the safety and efficiency of medical services are improved.

[0029] Example 2 refer to Figure 3 and Figure 4 The difference between this embodiment and the above embodiment is that the support consists of two arc-shaped connecting rods 131, which are symmetrically arranged on one side of the lifting ring 110. The two arc-shaped connecting rods 131 correspond one-to-one with the two sets of pulleys. One end of the arc-shaped connecting rod 131 is integrally formed with the lifting ring 110, while the bushing 133 is located at the end of the arc-shaped connecting rod 131 away from the lifting ring 110. The inner arc surfaces of the two arc-shaped connecting rods 131 are arranged opposite each other. This arrangement increases the distance between the two pulleys and eliminates the connection between the two pulleys, making the trolley move more smoothly and flexibly, reducing the jamming caused by track bending, and reducing the probability of wear between the trolley and the track, thus extending the service life of the trolley and the track.

[0030] The implementation principle of this embodiment 2 is as follows: using an arc-shaped connecting rod 131 as a support makes the movement of the trolley on the track more flexible, better adaptable to different track shapes, reduces jamming caused by track bending, and improves the convenience and efficiency of infusion operation.

[0031] Example 3 refer to Figure 5 Since in practical applications, there is a possibility that some infusion poles may also have a hanging ring at the top, the difference between this embodiment and the above embodiment is that the hanging ring 110 includes a main hanging ring 111 and a secondary hanging ring 112. The main hanging ring 111 and the secondary hanging ring 112 are connected in an openable and closable manner. Two sets of pulleys are symmetrically arranged on one side of the main hanging ring 111. One end of the main hanging ring 111 is hinged to the secondary hanging ring 112. The other end of the main hanging ring 111 is provided with a magnetic suction piece 113, and the other end of the secondary hanging ring 112 is provided with an iron piece 114. The magnetic suction piece 113 is used to attract the iron piece 114.

[0032] The implementation principle of this embodiment 3 is as follows: The openable and closable design of the main ring 111 and the auxiliary ring 112 facilitates the hanging and removal of the hook at the top of the infusion rod. In actual use, medical staff can easily open the auxiliary ring 112, put the hook at the top of the infusion rod into the main ring 111, and then use the adsorption effect of the magnetic plate 113 and the iron plate 114 to close the auxiliary ring 112, ensuring that the infusion rod is stably suspended on the ring 110.

[0033] Example 4 refer to Figure 6 and Figure 7 This application discloses an infusion slide rail, including a track body 150. The track body 150 is used to guide and limit the sliding of the trolley in the above embodiment. An infusion slide groove 151 for the pulley assembly to be embedded is provided on the track body 150. The infusion slide groove 151 is opened around the circumference of the track body 150. The support part is embedded in the infusion slide groove 151. The design of the infusion slide groove 151 enables the pulley assembly to be stably embedded in the track body 150, ensuring the movement direction and stability of the trolley on the track.

[0034] The implementation principle of this embodiment 4 is as follows: The slide rail of this embodiment provides stable guidance and limiting function for the infusion trolley through the design of the infusion chute 151, so that the trolley can move smoothly on the track, better cooperate with the use of the infusion trolley, and improve the safety and efficiency of infusion operation.

[0035] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
