[0002] The dripper is the Murphy's dropper, also known as the drip pot, which is an important part of the infusion tube. The dripper is the penultimate structure of the disposable infusion set. It has the function of displaying the dripping rate and the first exhaust. It can also be used for emergency addition of drugs. The traditional dripper is made of PVC as the raw material. High-performance polyolefin thermoplastic elastomer is considered to be a safer and higher-performance material for making Murphy's dropper. However, the current dripper still has the following shortcomings:

[0003] For example, the patent document with application number 02120080233.2 discloses a drip bucket for an infusion set. The drip bucket for an infusion set increases the size of the drug-adding rubber plug, expands the area of ​​the drug injection port, reduces the possibility of self-injury caused by improper operation of medical staff during the drug-adding process, and improves the safety of the drug-adding operation. However, it does not have a defoaming structure, and certain bubbles will be generated during the infusion process, causing certain dangers.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a drip bucket for reducing bubbles is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] like Figures 1 to 4 As shown, a bubble-reducing drip bucket comprises a drip bucket tube body 1 and a defoaming component 3, a sealing fixing ring 2 is installed on the upper surface of the drip bucket tube body 1, and the drip bucket tube body 1 is an integrally formed PVC plastic structure, the defoaming component 3 is arranged inside the drip bucket tube body 1, and the defoaming component 3 comprises a fixing rod 301, a drip drainage groove 302, a sealing ring 303, a defoaming rod 304, a defoaming protrusion 305 and a filter mesh plate 306, the fixing rod 301 is arranged on the lower surface of the sealing fixing ring 2, and a drip drainage groove 302 is opened inside the fixing rod 301, a sealing ring 303 is arranged on the upper end of the fixing rod 301, and the upper surface of the sealing ring 303 is connected to the lower surface of the sealing fixing ring 2, a defoaming rod 304 is installed on the lower end surface of the fixing rod 301, and a defoaming protrusion 305 is arranged on the outer surface of the defoaming rod 304, and a filter mesh plate 306 is installed at the lower end of the drip bucket tube body 1.

[0024] The specific operation is as follows. When in use, during the infusion process, the liquid passes through the mounting tube 4 connected to the infusion tube, and then passes through the sealing fixing ring 2 to enter the drip drainage groove 302 inside the fixing rod 301, and falls into the drip bucket tube body 1 under the guidance of the drip drainage groove 302. Since the output end of the drip drainage groove 302 is at a lower position inside the drip bucket tube body 1, splashing of the liquid when dripping can be avoided, and the generation of bubbles can be reduced. At the same time, the liquid will be filtered by the filter mesh plate 306 to filter out the bubbles in the liquid. If there are too many bubbles in the liquid inside the drip bucket tube body 1, the drip bucket tube body 1 will be squeezed to drive the bubbles in the liquid to contact with the defoaming protrusion 305 on the surface of the defoaming rod 304 to puncture it.

[0025] Please refer to Figure 3 , the sealing fixed ring 2 is installed with a mounting tube 4, and a dosing component 5 for convenient dosing is arranged on the surface of the mounting tube 4, the dosing component 5 includes a dosing tube 501, a cross-opening membrane 502 and a supporting ring 503, and the dosing tube 501 is arranged on the left surface of the mounting tube 4, the inner side of the input end of the dosing tube 501 is connected with a cross-opening membrane 502, and the outer surface of the upper end of the dosing tube 501 is installed with a supporting ring 503, the dosing component 5 also includes a snap-on cover 504 and an elastic sealing ring 505, and the outer side of the input end of the dosing tube 501 is snap-connected with the snap-on cover 504, and the lower end of the inner surface of the snap-on cover 504 is provided with an elastic sealing ring 505;

[0026] The specific operation is as follows. When in use, the snap-on cover 504 is removed. Since the surface of the cross-opening membrane 502 is provided with an opening, the dosing needle can be inserted into the dosing tube 501 without applying force. After the dosing needle is taken out, due to the elastic effect of the cross-opening membrane 502, its opening will quickly rebound and recover to prevent external impurities from entering the dosing tube 501. After the dosing is completed, the snap-on cover 504 is snap-connected with the upper end of the dosing tube 501, so that the snap-on cover 504 further seals the dosing tube 501, and the elastic sealing ring 505 can improve the sealing performance of the snap-on cover 504.

[0027] Please refer to Figure 1 to Figure 2 , an elastic sealing pad 6 is connected to the inner surface of the mounting tube 4, and the elastic sealing pad 6 extends upward to the top of the mounting tube 4, a thermoplastic polyolefin protective layer 7 is provided on the outer surface of the drip bucket tube body 1, and the thermoplastic polyolefin protective layer 7 is a soft elastic structure, a connecting tube 8 is installed at the bottom of the drip bucket tube body 1, and a sealing tube sleeve 9 is provided on the outside of the connecting tube 8, an exhaust pipe 10 is connected to the right side of the upper surface of the sealing fixing ring 2, and a sealing cover 11 is threadedly connected to the outer surface of the output end of the exhaust pipe 10;

[0028] The specific operation is as follows. When in use, the infusion tube is connected to the upper and lower sides of the drip bucket tube body 1 respectively through the installation tube 4 and the connecting tube 8. The elastic sealing gasket 6 and the sealing tube sleeve 9 can improve the tightness and sealing of the connection. The thermoplastic polyolefin protective layer 7 can improve the wear resistance of the drip bucket tube body 1. Open the sealing cover 11 and discharge the excess gas through the exhaust pipe 10.

[0029] In summary, if Figures 1 to 4 As shown, when the bubble-reducing drip bucket is used, first, the infusion tube is connected to the upper and lower sides of the drip bucket tube body 1 through the installation tube 4 and the connecting tube 8 respectively. The elastic sealing pad 6 and the sealing tube sleeve 9 can improve the tightness and sealing of the connection. During the infusion process, the liquid passes through the installation tube 4 connected to the infusion tube, and then passes through the sealing fixing ring 2 to enter the drip drainage groove 302 inside the fixing rod 301, and is guided by the drip drainage groove 302 to fall into the drip bucket tube body 1. Since the output end of the drip drainage groove 302 is at a lower position inside the drip bucket tube body 1, splashing of the liquid can be avoided when it drips, and the generation of bubbles can be reduced. At the same time, the liquid will be filtered by the filter mesh plate 306 to filter the bubbles in the liquid. If there are too many bubbles in the liquid inside the drip bucket tube body 1, the drip bucket tube body 1 is squeezed to drive the bubbles in the liquid to contact with the defoaming rod The defoaming protrusion 305 on the surface of 304 contacts and punctures it. When it is necessary to add medicine, the snap-on cover 504 is removed. Since the surface of the cross-opening membrane 502 is provided with an opening, the dosing needle can be inserted into the dosing tube 501 without applying force. After the dosing needle is taken out, due to the elastic effect of the cross-opening membrane 502, its opening will rebound and recover quickly to prevent external impurities from entering the dosing tube 501. After the dosing is completed, the snap-on cover 504 is snap-connected with the upper end of the dosing tube 501 through the snap-on connection, so that the snap-on cover 504 further seals the dosing tube 501, and the elastic sealing ring 505 can improve the sealing performance of the snap-on cover 504. During the use of the device, the thermoplastic polyolefin protective layer 7 can improve the wear resistance of the drip bucket tube body 1, open the sealing cover 11, and discharge the excess gas through the exhaust pipe 10.
