[0031] In order to better understand the technical solution of the present utility model, the embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0032] It should be clear that the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0034] An automatic infusion bottle changing device, such as Figure 1 As shown, it includes a mounting shell 1, a fixed frame 2, a two-axis movable platform 3, a mobile mounting seat 4, a disinfection mechanism 5, and an infusion needle 6, wherein the fixed frame 2, the two-axis movable platform 3, the mobile mounting seat 4, the disinfection mechanism 5 and the infusion needle 6 are all installed in the mounting shell 1, a plurality of infusion bottles are installed on the fixed frame 2, the mobile mounting seat 4 is arranged on the two-axis movable platform 3, and the disinfection mechanism 5 and the infusion needle 6 are installed on the mobile mounting seat 4. Specifically, in this embodiment, the infusion needle 6 is arranged on the mobile mounting seat 4 and is located on one side of the disinfection mechanism 5. The mobile mounting seat 4 moves the disinfection mechanism 5 to the bottle mouth of the infusion bottle to disinfect the bottle mouth, and then moves the infusion needle 6 to connect the infusion bottle for infusion. In a possible case, a built-in battery is also arranged in the mounting shell 1. The built-in battery adopts a 24V voltage 8AH lithium-ion battery, which can last for 12 hours after power failure.

[0035] like Figure 1-2 As shown, the mounting shell 1 includes a front shell 11 and a rear shell 12, the fixing frame 2 is mounted on the inner side of the rear shell 12, and the two-axis movable platform 3, the disinfection mechanism 5 and the infusion needle 6 are mounted on the inner side of the front shell 11. Specifically, in this embodiment, one side of the front shell 11 and one side of the rear shell 12 are hingedly connected, and the mounting shell 1 can be opened or closed through the side, so as to replace the infusion bottle inside the mounting shell 1 or to repair the device inside the mounting shell 1.

[0036] Furthermore, the mounting shell 1 is provided with an observation window 13. Specifically, in this example, the front housing 11 is provided with an observation window 13 so that the user can observe the use of the infusion bottle inside the mounting shell 1 at any time, and the observation window 13 is made of acrylic transparent plastic.

[0037] like Figure 1 As shown, the fixing frame 2 is provided with a plurality of first card interfaces 21. Specifically, in this example, the first card interface 21 is a U-shaped card interface, and there are three U-shaped card interfaces, which are equidistantly arranged, and play the role of locating the horizontal coordinates of the infusion bottle. When installing the infusion bottle, the neck of the infusion bottle is aligned with the U-shaped card interface and pushed in to complete the installation, and the infusion bottle is installed upside down on the fixing frame 2. The fixing frame 2 is preferably made of plastic. The fixing frame 2 is an infusion bottle holder that can accommodate 3 bottles, which is used to fix the infusion bottle and plays the role of locating the horizontal coordinates of the infusion bottle. The design caliber of the U-shaped buckle also fits the size of the mainstream infusion bottle and has a certain compatibility. When the size difference of the infusion bottle is too large, it can also be quickly compatible with infusion bottles of different sizes by replacing the buckle.

[0038] like Figure 1 As shown, the two-axis movable platform 3 includes a longitudinal moving mechanism 32 and a transverse moving mechanism 31. The longitudinal moving mechanism 32 is installed on the transverse moving mechanism 31, and the longitudinal moving mechanism 32 is controlled by the transverse moving mechanism 31 to move transversely. The mobile mounting seat 4 is on the longitudinal moving mechanism 32, and the longitudinal moving mechanism 32 controls the longitudinal movement of the mobile mounting seat 4. With the cooperation of the longitudinal moving mechanism 32 and the transverse moving mechanism 31, the mobile mounting seat 4 can achieve longitudinal and transverse movement.

[0039] like Figure 1As shown, the transverse moving mechanism 31 includes a transverse fixing frame 311, a transverse motor 312, a steering assembly 313, a transverse lead screw 314 and a transverse slide rail 315. The transverse motor 312 is mounted on the steering assembly 313, the steering assembly 313 is mounted on the transverse fixing frame 311, one end of the transverse lead screw 314 is mounted on the side of the steering assembly 313, the other end of the transverse lead screw 314 is rotatably connected to the transverse fixing frame 311, and the transverse slide rail 315 is mounted on the transverse fixing frame 311 and is located on both sides of the transverse lead screw 314. Specifically, in this example, the longitudinal moving mechanism 32 is mounted on the transverse lead screw 314 and is in sliding contact with the transverse slide rail 315. Two conical teeth (not shown) are arranged inside the steering assembly 313, one of which is mounted on the output end of the transverse motor 312, and the other is mounted on one end of the transverse lead screw 314. The two conical teeth are meshed and the central axes of the two conical teeth are perpendicular to each other.

[0040] like Figure 1 As shown, the longitudinal moving mechanism 32 includes a longitudinal fixing frame 321, a longitudinal motor 322, a longitudinal lead screw 323 and a longitudinal slide rail 324. The longitudinal fixing frame 321 is mounted on the transverse lead screw 314 and the transverse slide rail 315. The longitudinal motor 322 is mounted on the longitudinal fixing frame 321. The longitudinal lead screw 323 is mounted on the output end of the longitudinal motor 322. The longitudinal slide rail 324 is mounted on the longitudinal fixing frame 321 and is located on both sides of the longitudinal lead screw 323. Specifically, in this example, the movable mounting seat 4 is mounted on the longitudinal lead screw 323 and is in sliding contact with the longitudinal slide rail 324. In a possible case, since the sizes of various types of infusion bottles are different, a current detection module needs to be added to the control system connected to the longitudinal motor 322. When it is detected that the current of the longitudinal motor 322 increases to a threshold value, it is considered that the movement of the longitudinal motor 322 is hindered and the infusion needle 6 has contacted the bottle mouth of the infusion bottle.

[0041] like Figure 3As shown, the mobile mounting seat 4 is provided with a disinfection channel 41, a first fixed port 42 and a second fixed port 43, which are used to install the disinfection mechanism 5. The disinfection mechanism 5 includes a disinfectant bottle 51 and a disinfectant sponge 52. One end of the disinfection channel 41 is connected to the disinfectant bottle 51, and one end of the disinfection channel 41 is connected to the disinfectant sponge 52. Specifically, in this example, one end of the disinfection channel 41 is provided with a first fixed port 42, and the other end of the disinfection channel 41 is provided with a second fixed port 43. The first fixed port 42 and the second fixed port 43 are both opened on the mobile mounting seat 4. The openings of the first fixed port 42 and the second fixed port 43 are roughly circular. The disinfection channel 41 is provided in the mobile mounting seat 4, and the first fixed port 42 and the second fixed port 43 are connected to form a communicating vessel. The disinfectant bottle 51 is invertedly installed in the first fixed port 42, and the disinfectant sponge 52 is installed in the second fixed port 43. The disinfectant in the inverted disinfectant bottle 51 flows to the second fixed port 43 through the disinfection channel 41. When the disinfectant level in the second fixed port 43 is lower than the bottle mouth of the disinfectant bottle 51, air enters the disinfectant bottle 51, and the disinfectant bottle 51 automatically releases disinfectant to replenish the second fixed port 43. The disinfectant is absorbed by the disinfectant sponge 52, and then the disinfectant sponge 52 can disinfect the bottle mouth of the infusion bottle. The disinfectant sponge 52 is a porous sponge.

[0042] Furthermore, the disinfection channel 41 is also provided with a branch channel (not shown), and the branch channel is connected to the gas supply element (not shown). Specifically, in the present embodiment, a solenoid valve (not shown) is provided on the branch channel, and nitrogen is stored inside the gas supply element. When the mouth of the infusion bottle needs to be disinfected, the solenoid valve is opened and turned on, and the gas supply element is blown out from the branch channel, and then atomized through the disinfection sponge 52 (porous sponge) through the disinfection channel 41, and the disinfectant mist wets the bottle mouth for disinfection; after disinfection once, the solenoid valve is closed, and after waiting for a few seconds, the solenoid valve is opened again for a second disinfection. The gas supply element is preferably a high-pressure gas cylinder containing nitrogen.

[0043] like Figure 4 As shown, the mobile mounting seat 4 is also provided with a mounting groove 44 for mounting the infusion needle 6, and the mounting groove 44 is provided with a second card interface 45 and a third card interface 46. The mounting groove 44 is arranged on one side of the disinfection channel 41, and the infusion needle 6 is provided with a needle buckle 61, and the needle buckle 61 can be inserted into the second card interface 45, so that the infusion needle 6 is fixed in the mounting groove 44, and the infusion tube 62 connected to the infusion needle 6 is also installed in the mounting groove 44, and a detection element (not shown) is arranged in the third card interface 46. Specifically, in this embodiment, the detection element is a color sensor for detecting whether there is liquid passing through the infusion tube 62, and the infusion tube 62 is a transparent infusion tube.

[0044] The detection principle of the color sensor: when the infusion conditions are stable, the color of the infusion tube 62 is collected and recorded by the color sensor. If the color fluctuation within 5 seconds is less than the set threshold, the current color value is recorded and then compared in real time. As long as the color of the infusion tube 62 does not change, it means that the infusion has been going on; when the subsequent infusion is completed, the liquid level drops and the air reaches this point, due to the different refractive indices or colors of the air and the liquid medicine, the color difference breaks through the fluctuation range and exceeds the set threshold. When the color exceeds the threshold and lasts for 5 seconds, the infusion is considered to be completed.

[0045] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
