[0033] Please refer to Figure 1 The present embodiment provides a catheter feeding device 100 for a medical assembly machine, including a feeding assembly 110 and a lifting assembly 120. The feeding assembly 110 includes a support portion 111 and a hopper 112 mounted on the top of the support portion 111, and the hopper 112 is used to install the catheter; a receiving cavity communicating with the outside is opened laterally in the middle of the support portion 111, and the opening direction of the receiving cavity is perpendicular to the extension direction of the hopper 112; the feeding assembly 110 can move relative to the lifting assembly 120 so that the lifting assembly 120 is placed in the receiving cavity, and the lifting assembly 120 can drive the hopper 112 to rise or fall in the vertical direction.

[0034] Specifically, the catheter feeding device 100 for a medical assembly machine consists of two parts: a feeding component 110 and a lifting component 120. The feeding component 110 is used to realize automatic loading of the catheter, while the lifting component 120 is used to adjust the height of the feeding component 110 to facilitate manual filling of the feeding component 110.

[0035] Among them, the feeding assembly 110 includes a support portion 111 and a silo 112. The silo 112 is used to install a conduit. The support portion 111 is a rectangular frame structure, and a receiving cavity is provided in the middle thereof. The receiving cavity has an opening, and the opening is provided on the side of the support portion 111, so that the feeding assembly 110 can place the lifting assembly 120 from the side into the receiving cavity. In order to facilitate the movement of the feeding assembly 110, in one embodiment of the present application, a pulley 1112 is provided at the bottom of the support portion 111, and a handle 1113 is provided on the outer wall of the support portion 111. The operator can adjust the position of the feeding assembly 110 by pulling the handle 1113 and the pulley 1112, and move it to the lifting assembly 120, and use the receiving cavity opened on the side to set the lifting assembly 120 below the support portion 111.

[0036] The existing lifting assembly is usually composed of the tail of the support part placed below the support part. Since a certain guiding distance is required to move the feeding assembly to the position of the lifting assembly and place it below the support part, and since the silo on the top of the feeding assembly needs to be provided with a longer conduit, the guiding distance of the feeding assembly itself is longer, so that the support part needs to be separated from the lifting assembly. The space required for the feeding assembly and the lifting assembly to cooperate is larger, and the space utilization rate is low. In some areas with smaller space, the coordination of the feeding assembly and the lifting assembly is more inconvenient, which reduces the flexibility of use.

[0037] In the present application, the lifting assembly 120 is placed side by side on the support portion 111 instead of being placed at the tail of the feeding assembly 110. This greatly reduces the required coordination space and floor space for the feeding assembly 110 and the lifting assembly 120, and allows them to be flexibly coordinated even in areas with smaller spaces, thereby improving the reliability and flexibility of the catheter feeding device 100 for a medical assembly machine.

[0038] It should be noted that, in one embodiment of the present application, first, Figure 6 As shown, the inner wall of the accommodating cavity is provided with a guide wheel 1111 along the in and out direction of the lifting assembly 120. The guide wheel 1111 is used to abut the outer wall of the lifting assembly 120. The rotation direction of the rolling surface of the guide wheel 1111 is set in the same direction as the in and out direction of the lifting assembly 120.

[0039] Specifically, in order to allow the lifting assembly 120 to be placed more smoothly and quickly from the side of the feeding assembly 110 to the bottom of the support portion 111, the inner wall of the accommodating chamber is further provided with guide wheels 1111. Preferably, the inner walls on opposite sides of the accommodating chamber are provided with guide wheels 1111, and the guide wheels 1111 are arranged along the entry and exit direction of the lifting assembly 120. When the lifting assembly 120 enters the accommodating chamber below the support portion 111, its outer wall can abut against the guide wheels 1111. The relative rolling of the guide wheels 1111 and the outer wall can enable the lifting assembly 120 to enter the accommodating chamber more quickly and smoothly, thereby improving the feeding efficiency of the catheter feeding device 100 for the medical assembly machine.

[0040] Second, the accommodating cavity is set at the center position of the support part 111, the lifting component 120 is set in the accommodating cavity, the projection range of the silo 112 is located at two-thirds of the projection range of the lifting component 120, and the projection direction is the stacking direction of the silo 112 and the support part 111.

[0041] Specifically, to ensure that the lifting assembly 120 can smoothly raise or lower the feeding assembly 110, the accommodating cavity is provided at the center of the support portion 111. This allows for even force on opposite sides of the feeding assembly 110 when the lifting assembly 120 contacts the feeding assembly 110, thereby preventing the feeding assembly 110 from tilting due to uneven force. Furthermore, to prevent the feeding assembly 110 from sliding when the lifting assembly 120 raises or lowers the feeding assembly 110, the projection of the silo 112 is preferably located at two-thirds of the projection of the lifting assembly 120, ensuring sufficient contact area between the lifting assembly 120 and the silo 112.

[0042] Third, if Figure 2 As shown, one end of the silo 112 along the extension direction is connected to the outside, so as to connect the catheter in the silo 112 to the medical assembly machine; a baffle 1121 is provided at the other end of the silo 112, and the baffle 1121 can move along the extension direction of the silo 112.

[0043] Specifically, the silo 112 is used to place the catheter, and one end of the silo 112 along the extension direction of the catheter is connected to the outside to facilitate the connection of the catheter to the medical assembly machine to achieve automatic loading of the catheter; Figure 2 As shown, in order to limit the catheter, a baffle 1121 is provided at one end of the silo 112 away from the medical assembly machine. Since the length of the catheter is not fixed, the baffle 1121 can move along the extension direction of the silo 112 to adapt to the length of the catheter.

[0044] The present application provides a catheter feeding device 100 for a medical assembly machine, comprising a feeding assembly 110 and a lifting assembly 120. The feeding assembly 110 comprises a support portion 111 and a hopper 112 mounted on the top of the support portion 111. The hopper 112 is used to install catheters. A accommodating cavity communicating with the outside is opened laterally in the middle of the support portion 111. The opening direction of the accommodating cavity is perpendicular to the extension direction of the hopper 112. The feeding assembly 110 can move relative to the lifting assembly 120 so that the lifting assembly 120 is placed in the accommodating cavity, and the lifting platform is placed from the side of the hopper 112 to the bottom of the hopper 112 to reduce the footprint of the catheter feeding device. The lifting assembly 120 can drive the hopper 112 to rise or fall in the vertical direction. The above-mentioned catheter feeding device 100 for a medical assembly machine can enable the lifting assembly 120 to be placed from the side of the support portion 111 to the bottom of the hopper 112, thereby reducing the footprint of the catheter feeding device and improving space utilization.

[0045] In one possible embodiment of the present application, a clamping portion is provided on the outer wall of the lifting assembly 120, and a limiting portion adapted to the clamping portion is correspondingly provided in the accommodating cavity. The limiting portion can be clamped and connected with the clamping portion to limit and fix the lifting assembly 120 and the support portion 111.

[0046] Specifically, when the lifting assembly 120 is arranged in the accommodating cavity of the feeding assembly 110, in order to ensure the matching stability of the lifting assembly 120 and the feeding assembly 110 and prevent the feeding group assembly from moving and causing displacement or material slipping during the lifting process, the outer wall of the lifting assembly 120 is also provided with a clamping portion, and correspondingly, a limiting portion adapted to the clamping portion is provided in the accommodating cavity, and the limiting portion can be clamped in the clamping portion, so that the position of the lifting assembly 120 and the support portion 111 is fixed.

[0047] It should be noted that the present application does not impose any restrictions on the specific arrangement of the clamping part and the limiting part. The clamping part can be a groove, and the limiting part can be a protruding structure that matches the shape of the groove. Similarly, the groove can also be a rectangular groove, a circular groove, etc. It is only necessary to ensure that the limiting part and the clamping part are compatible so that the limiting part can be stably clamped in the clamping part.

[0048] For example, please refer to Figure 3 、 Figure 4 and Figure 5 A fixing block 121 is convexly provided on the side of the lifting component 120 facing away from the opening of the accommodating chamber, and a slope structure 1211 is provided on the side of the fixing block 121 facing the outer wall of the lifting component 120; a fixing lock 113 is correspondingly provided in the accommodating chamber, and the fixing lock 113 has a wedge-shaped portion 1131 adapted to the slope structure 1211 of the fixing block 121; the lifting component 120 is arranged in the accommodating chamber, and the wedge-shaped portion 1131 of the fixing lock 113 can be clamped with the fixing block 121 and attached to the slope structure 1211 of the fixing block 121, so that the lifting component 120 and the support portion 111 are limited and fixed.

[0049] Specifically, if Figure 5 As shown, a fixing block 121 is provided on one side of the lifting assembly 120 facing away from the opening of the accommodating cavity, and the fixing block 121 has a slope structure 1211; correspondingly, a fixing lock 113 is provided in the accommodating cavity, and the fixing lock 113 has a wedge-shaped portion 1131. The slope of the wedge-shaped portion 1131 can be fitted with the slope of the fixing block 121, so that the wedge-shaped portion 1131 is fixedly engaged with the fixing block 121, thereby limiting and fixing the lifting assembly 120 and the support portion 111.

[0050] In one embodiment of the present application, Figure 4 As shown, the lifting assembly 120 includes a shell 122 and a motor arranged in the shell 122. The output shaft of the motor extends toward the setting direction of the silo 112. A lifting plate 123 is provided at the end of the output shaft, and the silo 112 is provided on the lifting plate 123.

[0051] Specifically, if Figure 4As shown, the lifting assembly 120 includes a housing 122, within which is disposed a motor, preferably a linear motor or a lead screw motor. The motor's output shaft is provided with a lifting plate 123, which is capable of contacting the bottom of the silo 112. The motor drives the lifting plate 123 in a vertical direction to move the silo 112 vertically.

[0052] Alternatively, as Figure 3 As shown, in order to limit the conduits in the silo 112 and prevent the conduits from falling due to position movement when the silo 112 is lifted or lowered by the lifting assembly 120, sealing plates 130 are provided on opposite sides of the silo 112, and the sealing plates 130 are vertically arranged on the top of the support portion 111 to enclose and form a accommodating cavity; when there are multiple silos 112, multiple silos 112 are arranged side by side on the top of the support portion 111 to facilitate the orderly placement of multiple groups of conduits, so that the conduits can be loaded in an orderly manner; at the same time, when there are multiple silos 112, in order to ensure that each silo 112 can rise or fall stably, multiple lifting plates 123 are also provided accordingly, so that the lifting plates 123 correspond one to one to the silos 112.

[0053] The working principle of the catheter feeding device 100 for the medical assembly machine is as follows:

[0054] First, the feeding assembly 110 is moved to the lifting assembly 120 via the support portion 111. The feeding assembly 110 is then moved so that the lifting assembly 120 is positioned from the side of the support portion 111 into the receiving chamber below the support portion 111. The sidewalls of the lifting assembly 120 can quickly enter the receiving chamber via the guide wheels 1111 on the inner wall of the receiving chamber. After the lifting assembly 120 is placed in the receiving chamber, the fixed lock 113 of the receiving chamber and the fixed block 121 of the lifting assembly 120 are used to limit and fix the lifting assembly 120 and the feeding assembly 110. The lifting assembly 120 can raise or lower the hopper 112 via the motor-driven lifting plate 123, facilitating manual handling of the catheter bin to achieve the supply of catheters.

[0055] The above description is merely an optional embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.

[0056] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
