[0041] This embodiment provides a liquid bottle puncture device, such as Figure 1 As shown. The liquid bottle piercing device 1 comprises:

[0042] Rack 10;

[0043] The puncture device seat 20 is fixedly connected to the frame 10 and is used for the puncture liquid bottle 50;

[0044] A support assembly 30, the support assembly 30 is slidably connected to the frame 10, and the support assembly 30 is used to fix the bottle mouth of the liquid bottle 50;

[0045] The pressing assembly 40 is slidably connected to the frame 10 , and is used to abut against the bottom of the liquid bottle 50 and slide toward the puncture device seat 20 .

[0046] The frame 10 provides the overall support structure of the device, ensuring the stability and symmetry of each component; the puncture device seat 20 is fixed on the frame 10, and is specifically used to perform the puncture operation on the liquid bottle 50; during operation, the bracket assembly 30 is slidably connected to the frame 10, and can be flexibly adjusted to adapt to liquid bottles 50 of different specifications to ensure that the bottle mouth can be firmly fixed; the pressing assembly 40 is also slidably connected to the frame 10, so that it moves downward during operation to abut the bottom of the liquid bottle 50; when the pressing assembly 40 moves downward, it will apply pressure to stably position the liquid bottle 50 under the fixation of the bracket assembly 30; then, the pressing assembly 40 continues to slide downward, directly pushing the liquid bottle 50 to the puncture device seat 20 to complete the puncture operation.

[0047] The frame 10 provides overall support to ensure the stability and symmetry of each part. The puncture holder 20 is fixedly connected to the frame 10 and is specifically used for puncturing the liquid bottle 50. The bracket assembly 30 is slidably connected to the frame 10, flexibly adapting to the needs of liquid bottles of different specifications, effectively fixing the mouth of the liquid bottle, and avoiding the deflection phenomenon during the puncture process. At the same time, the sliding design of the pressing assembly 40 enables it to move downward accurately and abut the bottom of the liquid bottle to ensure that the bottle is stably positioned with the support of the bracket assembly 30. The liquid bottle puncture device 1 not only improves the accuracy of puncture, but also significantly enhances the compatibility of the device and the ease of operation.

[0048] In some embodiments, Figure 1 The frame 10 is provided with a guide rail 11 , the support assembly 30 and the pressing assembly 40 are respectively slidably connected with the guide rail 11 , and the puncture device seat 20 is arranged at the end of the guide rail 11 .

[0049] When the pressing assembly 40 is controlled, it moves upward or downward along the guide rail 11; when moving upward, the liquid bottle is placed and fixed on the bracket through the bracket assembly 30, and the bottle mouth of the liquid bottle 50 is accurately positioned through the bracket, thereby ensuring the stability of the liquid bottle 50 during the puncture process. In this process, the sliding connection design of the bracket assembly 30 and the pressing assembly 40 ensures the stability of the operation and avoids tilting or deviation.

[0050] In some embodiments, Figure 2 The puncture device seat 20 includes a base 21 and a puncture needle 22 , wherein the base 21 is fixedly connected to the frame 10 , and the puncture needle 22 is fixedly connected to the base 21 .

[0051] In some embodiments, Figure 3 The support assembly 30 includes a supporting member 31 and an elastic clip 32 , wherein the elastic clip 32 is engaged with the supporting member 31 ; the supporting member 31 is provided with a first through hole 311 , and the bottle mouth of the liquid bottle 50 is passed through the first through hole 311 .

[0052] The supporting member 31 provides a stable supporting platform so that the liquid bottle 50 can be securely fixed; and the elastic clip 32 can adapt to the bottle mouths of liquid bottles of different diameters through a chimeric connection to ensure that the bottle mouth is accurately positioned in the first through hole 311.

[0053] Specifically, when the elastic clip 32 fixes the liquid bottle 50, it can apply an appropriate clamping force to the bottle mouth through its elastic characteristics to prevent the bottle mouth from moving or tilting during the puncture process; this not only improves the accuracy of the puncture, but also reduces the risk of liquid bottle breakage due to improper operation.

[0054] In some embodiments, Figure 3 The elastic clip 32 includes a connecting portion 321 and a clamping portion 322, the connecting portion 321 and the clamping portion 322 are connected in a "human" shape; grooves 312 are provided on both sides of the supporting member 31, the connecting portion 321 and the grooves 312 are engaged and connected; the clamping portion 322 is used to elastically clamp the bottle mouth of the liquid bottle 50.

[0055] The elastic clip 32 is composed of a connecting portion 321 and a clamping portion 322, which are connected in a "human" shape, so that the clamping portion 322 has good elasticity. When the device is working, the clamping portion 322 automatically clamps the bottle mouth of the liquid bottle 50 through elastic action to ensure the stability of the liquid bottle during the puncture process. The connecting portion 321 is engaged with the groove 312 of the supporting member 31, providing additional support and positioning to prevent the liquid bottle from deflecting or tilting during the clamping process.

[0056] In some embodiments, Figure 4 , 5 The pressing assembly 40 includes a base plate 41, a fixing member 42, an elastic member 43 and a cover plate 45; the fixing member 42 is movably connected to the base plate 41, the cover plate 45 closes the base plate 41, one end of the elastic member 43 is connected to the fixing member 42, and the other end is connected to the cover plate 45.

[0057] The base plate 41 is fixed on the frame 10 to provide support and fixing points for the pressing assembly 40; the fixing member 42 is movably connected to the base plate 41 and is used to fix the position of the liquid bottle 50 during the puncture process. The elastic member 43 connects the fixing member 42 and the cover plate 45 to provide elastic force, so that the cover plate 45 and the base plate 41 can be pressed downward to abut the bottom of the liquid bottle 50 when subjected to the force of the fixing member 42. The cover plate 45 closes the base plate 41 and together with the base plate 41, forms the top structure of the pressing assembly 40. By controlling the movement of the pressing assembly 40 along the guide rail 11, the liquid bottle 50 can be stably fixed and punctured, thereby improving the efficiency and consistency of the puncture operation.

[0058] In some embodiments, Figure 4 , 5 The substrate 41 is provided with a second through hole 411 , and the fixing member 42 is movably disposed in the second through hole 411 .

[0059] In some embodiments, Figure 4 , 5 The pressing assembly 40 includes a pressure sensor 45 , which is disposed between the cover plate 44 and the elastic member 43 , and is used to detect and receive the pressure of the elastic member 43 .

[0060] The pressing assembly 40 further includes a pressure sensor 45, which is located between the cover plate 44 and the elastic member 43. It is used to detect and receive the pressure exerted on the elastic member 43. In this way, the pressure sensor 45 can monitor the pressure applied by the pressing assembly 40 to the liquid bottle 50 to ensure the stability and safety of the puncture process. This helps to determine whether the puncture force is appropriate and whether the liquid bottle is firmly fixed on the pressing assembly. Through the feedback of the pressure sensor 45, the puncture process can be optimized and the puncture efficiency and accuracy can be improved.

[0061] In some embodiments, Figure 3 , 4 , 5. The support assembly 30 further includes a first push connector 33, and the first push connector 33 is fixedly connected to the supporting member 31;

[0062] The pressing assembly 40 further includes a second pushing connecting member 46, and the second pushing connecting member 46 is fixedly connected to the base plate 41;

[0063] The first pushing connector 33 and the second pushing connector 46 are slidably connected to the guide rail 11 respectively.

[0064] The first push connector 33 is fixedly connected to the support member 31 in the bracket assembly 30. When the bracket assembly 30 moves along the guide rail 11, the first push connector 33 provides the necessary driving force so that the bracket assembly can slide smoothly along the guide rail.

[0065] The second pushing connecting member 46 is fixedly connected to the base plate 41 in the pressing assembly 40. The second pushing connecting member 46 provides a driving force for the pressing assembly 40, ensuring that the pressing assembly 40 can accurately move along the guide rail.

[0066] The guide rail 11 is a track for the support assembly 30 and the pressing assembly 40 to move. The first push connector 33 and the second push connector 46 are slidably connected to the guide rail 11 to ensure that the support assembly 30 and the pressing assembly 40 maintain linear motion when moving on the guide rail 11, thereby accurately controlling the positioning and puncture of the liquid bottle.

[0067] This embodiment provides a liquid bottle puncturing method, which uses the above-mentioned liquid bottle puncturing device 1 to perform liquid bottle puncturing, including the following steps:

[0068] The pressing assembly 40 is controlled to move upward along the guide rail 11 to install the liquid bottle 50 on the bracket assembly 30. The liquid bottle 50 is automatically fixed in the center under the action of the elastic clip 32.

[0069] The pressing assembly 40 is controlled to move downward along the guide rail 11 to abut against the liquid bottle 50, and the fixing member 42 contacts and fixes the liquid bottle 50. The fixing member 42 is stressed, and the pressure is transmitted to the pressure sensor 45 through the elastic member 43 to determine whether the liquid bottle 50 is fixed stably; the puncture device seat 20 is installed below the guide rail 11;

[0070] The pressing assembly 40, the liquid bottle 50 and the support assembly 30 move downward as a whole to complete the puncture of the liquid bottle.

[0071] The pressing assembly 40 moves upward along the guide rail 11 under control to install the liquid bottle 50 on the bracket assembly 30. In this process, the liquid bottle 50 is automatically fixed in the center under the action of the elastic clip 32 to ensure that the position of the liquid bottle is accurate.

[0072] The pressing assembly 40 is controlled to move downward along the guide rail 11, and contacts and fixes the liquid bottle 50. The fixing member 42 applies pressure after contacting the liquid bottle, and the pressure is transmitted to the pressure sensor 45 through the elastic member 43. The pressure sensor 45 detects and determines whether the liquid bottle is firmly fixed to ensure the safety and stability of the puncture process.

[0073] The puncture device seat 20 is installed below the guide rail 11 to prepare for the next puncture operation.

[0074] The pressing assembly 40, the liquid bottle 50 and the support assembly 30 as a whole move downward along the guide rail 11 to complete the puncture operation of the liquid bottle. This step enables the puncture needle to penetrate the liquid bottle and prepare for subsequent drug injection.

[0075] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
