Description

Technical Field

[0001] The utility model relates to the technical field of medical infusion, and particularly relates to a medical infusion tube. Background Art

[0002] Intravenous infusion is a treatment method that uses atmospheric pressure to input medicinal liquid into a patient's body. The vein is connected to a medicine bottle through an infusion tube, so that the medicinal liquid in the medicine bottle flows into the human body along the infusion tube, thereby achieving the treatment purpose.

[0003] During the infusion process, if the flow rate of the medicinal liquid is too fast, it will bring an uncomfortable feeling to the patient. Therefore, usually when a patient is receiving infusion, the flow rate of the medicinal liquid is adjusted to a relatively slow drip state, thereby avoiding the uncomfortable feeling during the infusion process. However, this will also result in a too long infusion time, especially when multiple bottles of medicinal liquid need to be input at one time.

[0004] During the infusion process, since the infusion tube is connected to the patient's vein blood vessel, when the patient needs to get up and move or go to the toilet, the infusion tube and the medicine bottle need to be moved together, and the medicine bottle also needs to be held high above a certain height to avoid blood backflow. The prior art has also designed various medicine infusion racks for the above problems, which can be pushed to move the medicine infusion rack, thereby driving the infusion tube and the medicine to move together. However, in reality, it is often another person who helps the patient hold the medicine bottle high and walks with the patient. This is not only very troublesome, but also the person holding the medicine bottle is very tired. Content of the Utility Model

[0005] To solve the above problems, that is, the problem that a patient receiving infusion needs to move the infusion tube and the medicine bottle together when walking, the utility model provides a medical infusion tube, which includes an upper tube and a lower tube. The upper tube and the lower tube are arranged in a plug-in manner. An insertion needle is arranged at the top end of the upper tube, and a Murphy's dropper and a flow regulator I are also installed on the upper tube; an infusion needle is arranged at the bottom end of the lower tube, and a flow regulator II is also installed on the lower tube.

[0006] A further setting of the utility model is that: an insertion interface is arranged below the flow regulator I, and the bottom end of the upper tube penetrates through the insertion interface; a plug connector adapted to the insertion interface is arranged at the top end of the lower tube, the lower tube is communicated with the plug connector, and a communication hole adapted to the upper tube is arranged on the plug connector.

[0007] A further setting of the utility model is that: the plug connector is made of elastic rubber.

[0008] A further arrangement of the present utility model is that: an exhaust pipe is further provided between the plug connector and the second flow regulator, the exhaust pipe is communicatively connected to the lower pipe, a plug cap is provided at one end of the exhaust pipe departing from the lower pipe, and one end of the exhaust pipe departing from the lower pipe is higher than the plug interface.

[0009] The beneficial effects of the present utility model are as follows:

[0010] Through the cooperation of the plug interface and the plug connector, the purpose of disassembling the lower pipe from the upper pipe can be achieved. By the first flow regulator, the purpose of controlling the opening degree of the upper pipe can be achieved, and by the second flow regulator, the purpose of controlling the opening degree of the lower pipe can be achieved. Furthermore, when the upper pipe and the lower pipe are disassembled, the first flow regulator can be used to block the upper pipe to prevent the liquid medicine from flowing out, and the first flow regulator can be used to block the lower pipe to prevent the liquid medicine in the lower pipe from flowing out and blood from returning. At the same time, it can also prevent air from entering the lower pipe. Further, when the patient needs to get up and walk or go to the toilet, the connection between the upper pipe and the lower pipe can be temporarily cut off first, making the movement more convenient. After coming back, the upper pipe and the lower pipe can be quickly connected together to continue the infusion, and the operation is simple and convenient. Description of the Drawings

[0015] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0016] The present utility model provides a medical infusion tube, which includes an upper pipe 1 and a lower pipe 2. The upper pipe 1 and the lower pipe 2 are inserted and connected. The top end of the upper pipe 1 is communicatively connected with an infusion needle 11, and the infusion needle 11 is used to insert into the medicine bottle to connect the medicine bottle with the upper pipe 1. A Murphy's dropper 12 and a first flow regulator 13 are also installed on the upper pipe 1. The Murphy's dropper 12 can play the roles of displaying the drip rate and exhausting air, and the first flow regulator 13 can be used to control the opening degree of the upper pipe 1, that is, to control the flow rate of the liquid medicine in the upper pipe 1.

[0017] The bottom end of the lower tube 2 is connected to an infusion needle 21, which is used to pierce into the vein of a patient to achieve the effect of infusing medicine into the vein. A second flow regulator 22 is also installed on the lower tube 2, and the second flow regulator 22 is used to control the opening degree of the lower tube 2.

[0018] Below the first flow regulator 13, there is a cylindrical socket 14. The socket 14 is fixedly connected to the bottom end of the first flow regulator 13. The bottom end of the upper tube 1 passes through the socket 14. The top end of the lower tube 2 is fixedly connected to a plug connector 23. The plug connector 23 is adapted to the socket 14. A communication hole 231 adapted to the upper tube 1 is formed in the plug connector 23. The lower tube 2 is communicated with the communication hole 231. The upper tube 1 can be coaxially inserted into the communication hole 231. In this way, not only can the purpose of connecting the upper tube 1 and the lower tube 2 be achieved, but also the positioning function can be realized.

[0019] The plug connector 23 is made of elastic rubber. In this way, when it is inserted into the socket 14 and when the upper tube 1 is inserted into the communication hole 231, the connection can be more stable, and at the same time, the sealing performance can be enhanced.

[0020] An exhaust pipe 24 is also provided between the plug connector 23 and the second flow regulator 22. One end of the exhaust pipe 24 is communicated with the lower tube 2 through a tee. A plug 241 is detachably installed at the end of the exhaust pipe 24 away from the lower tube 2, and the end of the exhaust pipe 24 away from the lower tube 2 is also set higher than the socket 14.

[0021] During use: First, adjust the first flow regulator 13 and the second flow regulator 22 to make the opening degrees of the upper tube 1 and the lower tube 2 zero, that is, the liquid medicine cannot flow in the upper tube 1 and the lower tube 2. Then, pull out the plug connector 23 from the socket 14. At this time, the infusion is interrupted, and the patient can move only with the lower tube 2, making the movement more convenient.

[0022] Secondly, when it is necessary to continue the infusion, insert the plug connector 23 back into the socket 14, then remove the plug 241, and open the first flow regulator 13. At this time, the liquid medicine will flow downward, first filling the pipeline between the exhaust pipe 24 and the flow regulator, and then the liquid medicine will flow into the exhaust pipe 24. When the liquid medicine flows out from the end of the exhaust pipe 24 away from the lower tube 2, immediately cover the plug 241 back to achieve the purpose of discharging the air in the pipeline between the first flow regulator 13 and the second flow regulator 22 through the exhaust pipe 24.

[0023] It should be noted that if there are still air bubbles remaining on the inner wall of the pipeline after exhausting through the exhaust pipe 24, the upper tube 1 or the lower tube 2 can be flicked to drive the air bubbles attached to the inner wall into the Murphy's dropper 12.

[0024] Finally, open the second flow regulator 22 to make the liquid medicine in the lower tube 2 flow, and the infusion can be resumed.

[0025] In summary, through the cooperation of the insertion interface 14 and the insertion joint 23, the present utility model can achieve the purpose of disassembling the lower tube 2 from the upper tube 1. By means of the flow regulator I 13, the purpose of controlling the opening degree of the upper tube 1 can be achieved, and by means of the flow regulator II 22, the purpose of controlling the opening degree of the lower tube 2 can be achieved. Furthermore, when the upper tube 1 and the lower tube 2 are disassembled, the flow regulator I 13 can be used to block the upper tube 1 to prevent the liquid medicine from flowing out, and the flow regulator II 13 can be used to block the lower tube 2 to prevent the liquid medicine in the lower tube 2 from flowing out and blood from returning. At the same time, it can also prevent air from entering the lower tube 2. Further, when the patient needs to get up and move around or go to the toilet, the connection between the upper tube 1 and the lower tube 2 can be temporarily cut off first to make the movement more convenient. After coming back, the upper tube 1 and the lower tube 2 can be quickly connected together to continue the infusion, and the operation is simple and convenient.
