Problems solved by technology

However, the device requires the needle point of the infusion set to be directly inserted into the mouth of the bottle during use, and it is easy to pollute the needle point due to incomplete disinfection of the bottle mouth, and even insert it into the patient's body again to cause infection of the patient.
If it is necessary to disinfect the bottle mouth with alcohol or iodophor before inserting the needle tip, multiple steps before infusion will be added, which will make the infusion process more complicated and increase the workload of medical staff.

Embodiment 1

[0033] For medical staff, in the dispensing room or injection room, the operating space is often limited, and even in a narrow space with dense crowds, the frequent release of a small amount of toxic and harmful gases and liquids in small doses will also cause long-term toxicity, causing certain harm to medical staff. Therefore, the present invention provides a device for collecting injection residual liquid, which can collect the gas and liquid discharged from the needle tip or liquid outlet of the infusion set before injection, so as to reduce the discharged air and liquid droplets with toxic particles in the medicine Dispersed into the air, after being inhaled by healthy people, it will cause damage to the basic tissues of healthy people, such as bone marrow and digestive system.

[0034] The collection device according to the present invention comprises a joint 200 joint. The joint is provided with a first channel 210 and a second channel 220 . The first channel 210 is us...

Embodiment 2

[0048] This embodiment is a further improvement to Embodiment 1, and repeated content will not be repeated.

[0049] An infusion set comprising the residual liquid collection device described in Embodiment 1.

[0050] Preferably, the infusion set at least includes an infusion tube and a residual liquid collecting device, and the residual liquid collecting device is connected to the liquid outlet end of the infusion tube through the first channel 210 of the first shape. Use the auxiliary infusion set for pre-injection venting. Preferably, the infusion set further includes an infusion needle. The residual liquid collecting device is connected with the liquid outlet port of the infusion needle through the first channel 210 in the second shape, so as to assist the infusion set with the infusion needle to perform degassing and drainage before injection. Preferably, the first channel 210 is provided with a fitting sealing cover. When the needle tip or the infusion tube is separat...

Abstract

The invention relates to a device for collecting injection residual liquid and an infusion set provided with the device. The liquid to be injected into the patient starts from the infusion bottle and goes to the indwelling needle or the needle tip through the infusion channel of the infusion tube. The device for collecting the residual injection night includes a joint and a first accommodating cavity. Wherein, the joint includes a first channel, which is used to communicate with the infusion channel of the infusion tube to collect gas and a small amount of liquid in the infusion channel; the second channel is communicated with the first channel and can control whether the joint is in communication with the external atmospheric environment; The third channel is in communication with the first channel and the second channel, and is used for connecting the first accommodating cavity. When the infusion channel is connected to the first channel, and the liquid in the infusion channel is close to the first channel, the gas and part of the liquid in the infusion channel enter into the first channel based on the rebound of the first accommodating cavity in the squeezed state. inside, so that the infusion channel is filled with medicinal liquid as much as possible.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for collecting injection residual liquid and an infusion set with the device. Background technique [0002] Chemotherapy is a common method for the treatment of tumors at present, using chemical drugs to kill cancer cells to achieve the purpose of treatment. Regardless of the route of administration, chemotherapy drugs circulate throughout most organs and tissues throughout the body. Chemotherapy drugs are mainly cytotoxic drugs, which spread throughout the body not only kill cancer cells but also damage normal cells in the body. Therefore, chemotherapy patients often experience side effects such as nausea, diarrhea, leukopenia and thrombocytopenia, and hair loss. Not only that, during the preparation of chemotherapy drugs, aerosols containing toxic particles can be formed into the human body through the skin and respiratory tract, causing serious damage to the ...
