[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0029] Medical needles are a type of medical device used in blood collection, infusion and other operations. The main functions of medical needles are as follows: collecting blood samples, infusion and surgery, etc. Medical needles are one of the most important tools in the medical process. They can help doctors and nurses treat and care more efficiently and accurately. There are currently two forms of medical syringe needles: plastic and glass. All-glass syringes are made of glass. They have the advantages of chemical corrosion resistance, strong heat resistance and easy cleaning. They are suitable for the preparation, transportation and storage of drugs and biological preparations. Compared with plastic syringes, the main advantage of all-glass syringes is that they are made of glass. Its high chemical stability can avoid plastic additives that may affect the quality of drugs; it has good heat resistance and can withstand high-temperature disinfection methods; at the same time, during the injection process, this syringe can achieve more accurate control of the dosage of the liquid medicine. All-glass syringes are widely used in the pharmaceutical and biological preparation industries, as well as scientific research. In terms of manufacturing process, cost, cleanliness and recyclability.

[0030] See also Figure 1-Figure 8 As shown, this embodiment provides a medical needle tube disinfection machine, including a shell 1. In the prior art, when disinfecting needle tubes, multiple needle tubes are placed together for immersion disinfection, but the outer walls of multiple needle tubes will collide to cause damage to the needle tubes, and each needle tube carries different harmful components. Mixing together may cause cross infection, resulting in different harmful components contaminating the needle tubes. At the same time, the medicine is mainly placed inside the needle tube. The prior art is not convenient for cleaning the inner wall of the needle tube separately, resulting in poor disinfection effect. Therefore, a cleaner 2 is provided inside the shell 1, and the cleaner 2 includes a cleaning member 25. The cleaning member 25 slides inside the shell 1. Considering that shaking will occur when cleaning the inner wall of the needle tube and affect the cleaning effect, the cleaner 2 also includes a clamping member 26. The clamping member 26 has two groups of symmetrical connecting plates 261, and each group of connecting plates 261 is composed of two connecting plates 261, wherein a third spring 262 is fixedly connected between the two connecting plates 261, wherein one connecting plate 261 is fixedly connected to the bottom of the inner cavity of the shell 1, and the other connecting plate 261 slides inside the shell 1. The clamping member 26 is used to fix the needle tube so that the cleaning member 25 extends into the inner wall of the needle tube for cleaning. Figure 1As shown, by placing the needle tube to be sterilized inside the clamp 26, the rebound force of the clamp 26 clamps and fixes the needle tube, and the end of the cleaning piece 25 is aligned with the inside of the needle tube. As the cleaning piece 25 slides inside the shell 1, the outer wall of the cleaning piece 25 is attached to the inner wall of the needle tube for friction cleaning, which is beneficial for cleaning and sterilizing each needle tube separately, avoiding cross infection when sterilizing multiple needle tubes. At the same time, the inner wall is cleaned, and the cleaning effect is better.

[0031] Considering that the cleaner 2 needs a power source to clean the inner wall of the needle tube, the cleaner 2 includes a motor 21, the outer shell of the motor 21 is fixedly connected to the surface of one end of the shell 1, the output shaft of the motor 21 is fixedly connected to a reverse screw rod 22, a sliding shaft 23 is provided above the reverse screw rod 22, one end of the sliding shaft 23 is fixedly connected to a transmission member 24, one end of the transmission member 24 is fixedly connected to a cleaning member 25, a plurality of sliding blocks 230 are provided inside the sliding shaft 23, the sliding blocks 230 are located in the recess of the reverse screw rod 22, and the sliding blocks 230 are adapted to the reverse screw rod 22, and the transmission member 24 includes There are two symmetrical trays 240, and a first spring 241 is fixedly connected between the two trays 240, one of the trays 240 is fixed at the end of the sliding shaft 23, and the other tray 240 is fixed at the end of the cleaning piece 25. When the power is turned on, the motor 21 is energized, and the reverse screw rod 22 is driven to move by the rotation of the output shaft of the motor 21. The reverse screw rod 22 drives the sliding shaft 23 to move through the sliding block 230, and the sliding shaft 23 drives the transmission member 24 to move. The cleaning piece 25 is driven to move through the transmission member 24, thereby realizing the reciprocating motion and rotation of the cleaning piece 25 on the inner wall of the needle tube.

[0032] Since the sizes of the needle tubes that need to be cleaned are different, it is necessary to adapt to the inner wall of the needle tube when cleaning the needle tube. Therefore, the cleaning piece 25 includes a support shaft 250, and a plurality of second springs 253 are provided on the surface of the support shaft 250. One end of the plurality of second springs 253 is fixedly connected to a plurality of support plates 252, and the surfaces of the plurality of support plates 252 are fixedly connected to a plurality of cleaning blocks 251. The outer wall of the cleaning block 251 is used to fit the inner wall of the needle tube. When cleaning the needle tube to be cleaned, the cleaning piece 25 is placed inside the needle tube, and the elastic force of the second spring 253 inside the cleaning piece 25 makes the surface of the cleaning block 251 expand to fit the inner wall of the needle tube. The cleaning block 251 can clean the inner wall of the needle tube by fitting the surface of the cleaning block 251 to the inner wall of the needle tube.

[0033] Since the glass syringe is in a used state, it needs to be disinfected before it can be used again. Therefore, a shell door 11 is provided on the surface of the shell 1, and a plurality of ultraviolet lamps 110 are provided on the surface of the shell door 11. The ultraviolet sterilization lamp (UV lamp) is actually a low-pressure mercury lamp, which emits ultraviolet rays after being excited by low-pressure mercury vapor (<10-2Pa). Through the irradiation of ultraviolet rays, the DNA (deoxyribonucleic acid) structure of microorganisms is destroyed and changed, so that the bacteria die immediately or cannot reproduce offspring, thereby achieving the purpose of sterilization. One end of the shell 1 is fixedly connected to a spray rack 12, and a plurality of nozzles 120 are evenly distributed on the surface of the spray rack 12. When spraying disinfectant, the nozzle 120 can be connected to a disinfectant source (not shown in the figure) through the water inlet end of the water pump, and the drainage end is connected to the inside of the spray rack 12, so that the disinfectant is introduced into the inside of the spray rack 12, and then sprayed from the plurality of nozzles 120 to the inside of the shell 1 to achieve the disinfection of the syringe.

[0034] In summary, the working principle of this solution is as follows:

[0035] When the medical needle tube needs to be cleaned, the shell door 11 is opened, and the needle tube is placed in the clamping member 26 so that the clamping member 26 fixes the needle tube. Then, the size of the cleaning member 25 is adjusted to fit the inner wall of the needle tube. The power is turned on to energize the motor 21. The reverse screw rod 22 is driven by the output shaft of the motor 21 to rotate, and the sliding shaft 23 is driven by the reverse screw rod 22 to move. The sliding shaft 23 drives the movement of the transmission member 24, so that the transmission member 24 drives the cleaning member 25 to move. After the power is turned on, the nozzle 120 starts to spray the disinfectant and does not cover the needle tube. The inner wall of the needle tube is cleaned and disinfected under the operation of the cleaning member 25. After the cleaning of the inner wall of the needle tube is completed, the ultraviolet irradiation lamp 110 is used to achieve a secondary comprehensive disinfection effect on the cleaned needle tube, and the needle tube and the inside of the sterilizer are dried, thereby improving the disinfection effect, reducing the possibility of contamination of the sterilizer, and improving safety and work efficiency.
