Description

Technical Field

[0001] The utility model relates to the field of medicine dispensing needles and provides a medicine dispensing needle for a medicine dispensing robot. Background Art

[0002] In the medical industry, the design and use of dispensers are particularly important to ensure the safe, accurate and efficient dispensing of liquid medicine. In particular, with the continuous advancement of intelligent medical technology, automated dispensing robots have become a key part of the modern medical process. Such robots can quickly and contaminant-free complete the dispensing of liquid medicine, while ensuring the safety of operation.

[0003] As the core component of a disposable dispensing device, the dispensing needle plays a vital role in the entire dispensing process. Its main functions include puncturing the stopper of the medicine bottle, aspirating and injecting the medicine, and balancing the pressure in the medicine bottle. This dispensing needle is specially designed to be used with an intelligent dispensing robot, thus achieving a high degree of automation in the dispensing process.

[0004] Traditional steel needle puncture devices for infusion sets have significant defects in the use scenarios of intelligent medicine dispensing robots. These defects not only affect the efficiency and safety of the medicine dispensing process, but also limit the further application of intelligent medicine dispensing robots in the medical field.

[0005] First of all, the position design of the liquid channel and air channel of the traditional steel needle puncture for infusion sets (including the inner needle and the outer needle, the inner needle is the gas channel, and the outer needle is the liquid channel) is not suitable for intelligent dispensing robots. In the working scene of the dispensing robot, the needle tip is usually facing downward, which requires that the position of the liquid channel and the air channel must be able to adapt to this specific usage posture. However, the liquid channel of the steel needle puncture for the infusion set is located in the outer layer, and the air channel is located in the inner layer. This design can easily cause liquid to flow out of the air channel when the needle tip is facing downward, thereby clogging the air filter, making it impossible for the gas in the medicine bottle to be discharged normally, forming positive pressure, and seriously affecting the normal progress of clinical infusion.

[0006] Secondly, the traditional steel needle puncture for infusion sets lacks the bracket and positioning hole for installation with the intelligent dispensing robot. This makes it impossible to stably and accurately install the steel needle puncture for infusion sets on the dispensing robot, thus affecting the accuracy and safety of the dispensing process.

[0007] In addition, conventional steel needle puncture devices for infusion sets do not have a dedicated handle design, which may cause operators to encounter difficulties during installation and removal, further reducing the efficiency of the dispensing process. Utility Model Content

[0008] The purpose of the utility model is to improve the traditional steel needle puncture device for infusion sets so that it can be used in the use scenario of the medicine dispensing robot. Specifically, in the use scenario of the medicine dispensing robot, the needle tip is facing downward. At this time, the liquid channel of the steel needle puncture device for infusion sets (the inner needle is the gas channel and the outer needle is the liquid channel) is on the top and the air channel is on the bottom. However, due to design reasons, the liquid may mistakenly enter the part that should be the gas channel and flow out from there. This will cause the liquid to block the air filter, which in turn prevents the gas in the medicine bottle from being discharged normally, forming a positive pressure in the bottle, and ultimately affecting the normal progress of clinical infusion.

[0009] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] A medicine dispensing needle for a medicine dispensing robot, comprising a main body lower part, a main body upper part arranged on the main body lower part, a filter element installation position and an outer needle arranged on the main body upper part, an inner steel needle arranged inside the outer needle, and a gap between the inner steel needle and the outer needle forming an air passage,

[0011] The tip of the inner steel needle extends outside the outer needle, and a liquid outlet is arranged on the tip of the needle. A side hole is arranged near the tip of the outer needle.

[0012] The side hole serves as an air inlet of an air passage, and the air passage is connected to an air outlet.

[0013] In the above technical solution, a filter element installation position is provided at the air outlet, a filter element is installed on the filter element installation position, and a filter membrane is provided inside the filter element.

[0014] In the above technical solution, a bracket is also arranged on the upper part of the main body.

[0015] In the above technical solution, a positioning hole is provided on the bracket.

[0016] In the above technical solution, a handle is also provided on the lower part of the main body.

[0017] In the above technical solution, the outer needle is made of plastic or stainless steel.

[0018] In the above technical solution, a liquid inlet is arranged on the lower part of the main body, the liquid inlet is communicated with the liquid inlet channel in the lower part of the main body, and the liquid inlet channel is communicated with the inner steel needle.

[0019] Because the utility model adopts the above technical means, it has the following beneficial effects:

[0020] The "dispensing needle" described in this patent has made comprehensive improvements to the defects described in the background technology. First, the liquid channel of the dispensing needle is designed in the inner layer, and the air channel is designed in the outer layer. This design fully adapts to the use scenario of the intelligent dispensing robot with the needle tip facing downward, avoiding the problem of liquid flowing out of the air channel. Secondly, the dispensing needle is equipped with a bracket and positioning holes that are installed in conjunction with the intelligent dispensing robot, ensuring that the dispensing needle can be stably and accurately installed on the robot. Finally, the dispensing needle is also provided with a special handle to facilitate installation and disassembly by the operator.

[0021] This patent effectively solves the defects of traditional steel needle puncture devices for infusion sets in the use scenarios of intelligent medicine dispensing robots by improving the position design of liquid channels and air channels, adding matching brackets and positioning holes, and setting up special handles, providing strong support for the widespread application of intelligent medicine dispensing robots in the medical field.

DETAILED DESCRIPTION

[0026] The following is a detailed description of the embodiments of the present invention. Although the present invention will be described and illustrated in conjunction with some specific implementations, it should be noted that the present invention is not limited to these implementations. On the contrary, modifications or equivalent replacements made to the present invention should be included in the scope of the claims of the present invention.

[0027] In addition, in order to better illustrate the present invention, numerous specific details are given in the following specific embodiments. Those skilled in the art will understand that the present invention can also be implemented without these specific details.

[0028] The utility model provides a dispensing needle for a dispensing robot, comprising a main body lower part, a main body upper part arranged on the main body lower part, a filter element installation position and an outer needle arranged on the main body upper part, an inner steel needle arranged inside the outer needle, and a gap between the inner steel needle and the outer needle forming an air channel.

[0029] The tip of the inner steel needle extends outside the outer needle, and a liquid outlet is arranged on the tip of the needle. A side hole is arranged near the tip of the outer needle.

[0030] The side hole serves as an air inlet of an air passage, and the air passage is connected to an air outlet.

[0031] In the above technical solution, a filter element installation position is provided at the air outlet, a filter element is installed on the filter element installation position, and a filter membrane is provided inside the filter element.

[0032] In the above technical solution, a bracket is also arranged on the upper part of the main body.

[0033] In the above technical solution, a positioning hole is provided on the bracket.

[0034] In the above technical solution, a handle is also provided on the lower part of the main body.

[0035] In the above technical solution, the outer needle is made of plastic or stainless steel.

[0036] In the above technical solution, a liquid inlet is arranged on the lower part of the main body, the liquid inlet is communicated with the liquid inlet channel in the lower part of the main body, and the liquid inlet channel is communicated with the inner steel needle.

[0037] Because the utility model adopts the above technical solution, it has the following outstanding substantive features and significant progress:

[0038] 1. Gas and liquid channel design: The dispensing needle adopts the structure of inner liquid channel and outer gas channel. This design ensures the effective separation of liquid and gas during the dispensing process, preventing liquid blockage and abnormal gas discharge.

[0039] 2. Special bracket and handle: The dispensing needle is equipped with a bracket and positioning hole that matches the intelligent dispensing robot, as well as a special handle. These designs enable the dispensing needle to be quickly and accurately installed on the dispensing robot, improving the efficiency and safety of dispensing.

[0040] 3. Double steel needle and plastic steel needle design: The dispensing needle provides two options: double steel needle and plastic steel needle to adapt to different production conditions and bottle stopper puncture requirements. The double steel needle is made of stainless steel, while the plastic steel needle is made of plastic injection molding. The two are different in the outer material of the air channel.

[0041] As the prior art that is relatively close to the present invention, a steel needle puncture device for an infusion set is provided. In order to allow those skilled in the art to better understand the difference between the steel needle puncture device for an infusion set in the prior art and the present application and to highlight the creativity of the present application, the following detailed description is made for this purpose:

[0042] Although the steel needle puncture device for infusion sets has certain similarities with the dispensing needle in structure, such as both have basic components such as puncture needle tip, liquid channel, air channel and air filter, there are significant differences in their functions and design details.

[0043] First, in terms of the design of the liquid channel, the traditional steel needle puncture for infusion sets usually sets the liquid channel on the outer layer so that the liquid can flow out of the medicine bottle. The dispensing needle adopts the opposite design, placing the liquid channel on the inner layer to ensure that the liquid can flow smoothly into the medicine bottle. This design difference directly affects the application effect of the dispensing needle in the intelligent dispensing robot.

[0044] Secondly, the design of the air channel is also an important difference between the two. The air channel of the steel needle puncture for the infusion set is usually located in the inner layer, while the air channel of the dispensing needle is set in the outer layer. This design difference enables the dispensing needle to better adapt to the working needs of the intelligent dispensing robot and effectively balance the pressure in the liquid medicine bottle.

[0045] In addition, the function of the air filter is also different between the two needle types. The air filter of the steel needle puncture for the infusion set is mainly used to filter out particles and bacteria in the air entering the medicine bottle, while the air filter of the dispensing needle is more focused on isolating the air inside and outside the bottle to prevent external particles and bacteria from entering the medicine bottle. This difference in function reflects the special needs of the two needle types in different application scenarios.

[0046] In addition to the above differences in structure and function, the dispensing needle also has some unique design features, such as positioning bracket, positioning hole and special handle, etc. These design features make it easier to install the dispensing needle on the intelligent dispensing robot and ensure the accuracy and stability of the dispensing process.

[0047] It is worth noting that double steel needles and plastic steel needles are the two main types of dispensing needles. They differ in material selection, with the outer layer of the air channel of the double steel needle using a stainless steel needle tube, while the plastic steel needle uses a plastic injection molded part. This difference in material selection is intended to adapt to different production conditions and puncture requirements.

[0048] In summary, although the steel needle puncture device for infusion sets has certain similarities with the dispensing needle in structure, it cannot be directly applied to the intelligent dispensing robot due to the design differences in liquid channels, air channels and air filters, as well as the lack of special design features such as positioning brackets, positioning holes and special handles. Therefore, it is particularly important to develop a dispensing needle designed specifically for intelligent dispensing robots.
