[0033] In the embodiments of this application, such as Figs. 1 to 3 As shown, the infusion device includes an infusion tubing 1 and a detection component 2; wherein,
[0034] The infusion tubing 1 includes a first tubing section 11, a second tubing section 12, and a three-way valve A13. The three-way valve A13 has three ports: a first port A, a second port A, and a third port A. The three-way valve A13 is equipped with a switch A that can switch the connection between the second port A or the third port A and the first port A. The outlet end of the first tubing section 11 is connected to the second port A, and the inlet end of the second tubing section 12 is connected to the first port A. (See [reference]). Fig. 1 ;
[0035] The detection assembly 2 comprises a liquid setting device 21, a detection device 22 and a three-way valve B 23. The three-way valve B 23 has three interfaces, i.e. a first interface B, a second interface B and a third interface B. The three-way valve B 23 is provided with a switching switch B capable of switching the second interface B or the third interface B to be in communication with the first interface B. The first interface B is in communication with the third interface A. The liquid setting device 21 is in communication with the second interface B. The liquid setting device 21 is capable of drawing out the drug liquid or drug-blood mixed liquid in the second pipe segment 12. The detection device 22 is in communication with the third interface B. The detection device 22 is capable of drawing the blood of the patient through the second pipe segment 12 and performing detection.
[0036] The infusion device can be used as an infusion device during the infusion process of the patient. In order to ensure that there is no air in the first pipe segment 11 and the second pipe segment 12, the medical staff needs to make the drug liquid fill the first pipe segment 11 and the second pipe segment 12 before infusion.
[0037] The liquid setting device 21 in the infusion device is capable of drawing out the drug liquid and drug-blood mixed liquid (liquid mixed by drug liquid and blood) in the second pipe segment 12, so that the blood of the patient fills the second pipe segment 12. Then the blood in the second pipe segment 12 is drawn by the detection device 22 and detection of blood-borne diseases is performed. In this way, the detection result can be obtained conveniently and quickly, and the medical staff can avoid occupational exposure to the greatest extent in the subsequent treatment or nursing operation. In addition, for the occupational exposure that has occurred, corresponding blocking measures can be taken more quickly, so as to reduce the risk of infection of the medical staff.
[0038] It is worth noting that when the drug liquid, drug-blood mixed liquid and blood in the second pipe segment 12 need to be drawn, the medical staff can adjust the position of the switching switch A so that the first interface A is in communication with the third interface A. At this time, the first interface A and the second interface A are in a disconnected state, so as to avoid that the drug liquid in the first pipe segment 11 is drawn into the liquid setting device 21 or the detection device 22.
[0039] During the infusion process, the position of the switching switch A can be adjusted again so that the first interface A is in communication with the second interface A, and the first interface A and the third interface A are in a disconnected state, so as to ensure that the infusion can be carried out normally.
[0040] Preferably, the first interface B and the third interface A are detachably connected.
[0041] The detection device 22 can be used to detect the blood of the patient during the first infusion. During the subsequent infusion process (after the detection result is obtained), the detection device 22 can not be used any more. The medical staff can take the unused detection device 22 from the third interface A, so as to reduce the use cost.
[0042] In some embodiments, the liquid setting device 21 comprises a storage bag 211 and a first suction pump 212. Referring to FIG. 2, the storage bag 211 is connected to the first suction pump 212.Fig. 2 ; wherein,
[0043] The liquid inlet of the storage bag 211 is communicated with the second interface B through the first suction pump 212, and the storage bag 211 can store the drug liquid and the drug-blood mixed liquid in the second pipe segment 12, so as to ensure that all the drug liquid in the second pipe segment 12 is extracted without affecting the detection result.
[0044] It should be noted that when the liquid placing device 21 extracts all the drug liquid and the drug-blood mixed liquid in the second pipe segment 12, the blood of the patient will fill the second pipe segment 12, and the detection device 22 can extract the pure blood in the second pipe segment 12, which has not contacted with the drug liquid, so as to ensure the accuracy of the detection to the greatest extent.
[0045] In some embodiments, the detection device 22 described above comprises a container 221 and a second suction pump 222; wherein,
[0046] The container 221 is provided with a partition plate 2211, which divides the cavity in the container 221 into a dilution cavity 2212 and a detection cavity 2213. In the embodiment, the detection cavity 2213 and the dilution cavity 2212 are arranged in an upper and lower manner, that is, in the initial state, the dilution cavity 2212 is located at the lower part of the detection cavity 2213, as shown in Fig. 3 The dilution cavity 2212 is provided with a dilution liquid, and the dilution cavity 2212 is communicated with the third interface B through the second suction pump 222. After the blood of the patient is extracted into the dilution cavity 2212 by the second suction pump 222, the blood is mixed with the dilution liquid, and the dilution of the blood is completed in the dilution cavity 2212.
[0047] The partition plate 2211 is provided with a through hole, and the dilution cavity 2212 and the detection cavity 2213 are communicated through the through hole. The detection cavity 2213 is provided with antigen antibodies for detecting viruses. After the dilution of the blood is completed, the medical staff can overturn the container 221 to change the positions of the detection cavity 2213 and the dilution cavity 2212. The diluted blood can enter the detection cavity 2213 through the through hole to combine with the antigen antibodies, so as to achieve the detection effect.
[0048] Of course, a visual window 2214 in communication with the detection cavity 2213 is arranged on the side wall of the accommodating container 221, and the visual window 2214 is closed by a transparent sealing plate to prevent the diluted blood from flowing out of the visual window 2214; the medical staff can observe the detection result through the visual window 2214. Preferably, the above-mentioned detection cavity 2213 includes a plurality of independent detection zones, and the plurality of detection zones are arranged along the length direction of the accommodating container 221; in the embodiment, the number of detection zones is four, and the four detection zones are AIDS zone, syphilis zone, hepatitis A zone and hepatitis B zone respectively, and corresponding antigens and antibodies are arranged in the four detection zones; the number of the through holes is the same as the number of the detection zones, and all the detection zones are in communication with the dilution cavity 2212 through the through holes. The above-mentioned arrangement can realize the detection of multiple blood-borne diseases, so as to improve the detection efficiency.
[0049] In some embodiments, the detection assembly 2 further includes a protective shell 24, and the liquid placement device 21, the detection device 22 and the three-way valve B 23 are arranged in the protective shell 24 to protect the liquid placement device 21, the detection device 22 and the three-way valve B 23. Preferably, a transparent observation window 241 is arranged on the protective shell 24, so that the medical staff can check the detection result through the observation window 241 and the above-mentioned visual window 2214.
[0050] In addition, the arrangement of the protective shell 24 can also avoid the situation that the blood of the patient leaks from the liquid placement device 21, the detection device 22 or the three-way valve B 23 to contact the medical staff or drop in the surrounding environment, so as to improve the safety of the infusion device during use.
[0051] In some embodiments, a rotary motor 242 is arranged in the protective shell 24, the action end of the rotary motor 242 is connected with the detection device 22, and the axis of the action end of the rotary motor 242 is parallel to the length direction of the detection device accommodating container 22. By operating the rotary motor 242, the accommodating container 221 can be flipped around the rotation axis of the rotary motor 242, so that the positions of the detection cavity 2213 and the dilution cavity 2212 are changed, so as to make the use of the infusion device more convenient.
[0052] In some embodiments, the operation ends of the first suction pump 212, the second suction pump 222 and the rotary motor 242 are arranged on the outer surface of the protective shell 24, and the medical staff can control the actions of the first suction pump 212, the second suction pump 222 and the rotary motor 242 by pressing the operation ends on the outer surface of the protective shell 24, so as to further improve the convenience of the infusion device during use.
[0053] It should be noted that the first suction pump 212 and the second suction pump 222 are both micro pumps.
[0054] In some embodiments, the first interface B and the second interface B are both provided with a one-way valve to avoid the backflow of the drug liquid or the drug blood mixture in the liquid placement device 21 into the body of the patient or into the detection device 22 to affect the detection result.
