Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to an infusion assisting device for switching liquid paths. Background Technique

[0002] At present, in clinical nursing work, for patients who need to infuse more than two kinds of liquids, disposable Y-shaped double-headed infusion sets are generally used. This kind of infusion set can hang two prepared liquids on the infusion rack at the same time. After the first infusion is completed, the nursing staff can directly switch the infusion line, which reduces the time for secondary drug preparation, reduces the round-trip time of the nursing staff, and at the same time reduces the anxious waiting time of the patient when the liquid needs to be changed.

[0003] However, practice shows that the Y-shaped double-headed infusion set has the following problems in the use process: during the infusion process of the Y-shaped double-headed infusion set, it is necessary for the nursing staff to manually open the switch of the second liquid path and close the first liquid path that has completed the infusion at the same time. However, during the switching process of the two infusion lines, first, if the liquid medicine in the first liquid path has been completely infused, but in the case of a large number of patients and the nursing staff being busy, it is impossible to close the first liquid path in time, then air will enter the inner end of the infusion tube, affecting the health and safety of the patient; second, if the second liquid path fails to be closed in time while the first liquid path is opened, resulting in both liquid paths being opened at the same time, causing incompatibility due to the mixing of two different liquid medicines, affecting the health and safety of the patient; third, if the liquid medicine in the first liquid path has been completely infused, but during the switching process, the first liquid path fails to be closed in time, the liquid medicine in the second liquid path will flow back into the first liquid path, affecting the input of the liquid medicine, and at the same time, it may be mixed with the remaining liquid medicine in the first liquid path, affecting the safety of the patient.

[0004] In the use process of the existing Y-shaped double-headed infusion set, whether the liquid path fails to be switched in time or there are operation errors during the switching process, it may affect the health and safety of the patient. Therefore, it is necessary to invent an infusion assisting device for switching liquid paths to solve the above problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] An infusion assistance device for switching liquid paths, as shown in the attached Figure 1 ~attached Figure 3 figures, includes a snap-fit mounting body 1. The inside of the snap-fit mounting body 1 is throughly provided with a first channel 2 and a second channel 3. A first extrusion structure 4 and a second extrusion structure 5 are respectively installed in the first channel 2 and the second channel 3. A signal sensor 6 is installed above the first extrusion structure 4 in the first channel 2, a first signal sensor 7 is installed below the first extrusion structure 4 in the first channel 2, a second signal sensor 8 is installed below the second extrusion structure 5 in the second channel 3, and an alarm component is installed on the surface of the snap-fit mounting body 1.

[0021] In the present utility model, the first channel 2 and the second channel 3 are used to place the first infusion tube and the second infusion tube of the Y-shaped double-headed infusion set. The first extrusion structure 4 is used to open and close the first infusion tube, and the second extrusion structure 5 is used to open and close the second infusion tube, so that only one of the two infusion tubes is in the open state during operation. The signal sensor 6 is used to detect whether there is liquid medicine flowing through the upper end of the first extrusion structure 4 in the first infusion tube, so as to judge whether the liquid medicine in the first infusion tube has been infused; the first signal sensor 7 is used to detect whether there is liquid medicine flowing through the lower end of the first extrusion structure 4 in the first infusion tube, so as to judge whether the first infusion tube is closed; the second signal sensor 8 is used to detect whether there is liquid medicine flowing through the lower end of the second extrusion structure 5 in the second infusion tube, so as to judge whether the second infusion tube is closed; through the detection results of the signal sensor 6, the first signal sensor 7 and the second signal sensor 8, and in cooperation with the reminder of the alarm component, accurate switching between the first infusion tube and the second infusion tube in the Y-shaped double-headed infusion set is realized, and the function of "either open or closed" for the two infusion tubes is realized, eliminating the occurrence of the situation where the two infusion tubes are infused simultaneously; greatly reducing the number of times that the nursing staff shuttles between the wards during centralized treatment, avoiding the risks brought to the patients due to untimely switching, and at the same time increasing the effective nursing workload of the nursing staff and improving work efficiency.

[0022] As shown in the Figure 1 attachment, it further includes a microcontroller, which is electrically connected to the signal sensor 6, the first signal sensor 7, and the second signal sensor 8, and the microcontroller is electrically connected to the alarm component. The alarm component includes a first sound and light alarm 9, a second sound and light alarm 10, and a third sound and light alarm 11.

[0023] The microcontroller is used to process the data signals transmitted by the signal sensor 6, the first signal sensor 7, and the second signal sensor 8, and at the same time control the first sound and light alarm 9, the second sound and light alarm 10, and the third sound and light alarm 11 to emit sound and light reminders.

[0024] As shown in the Figure 1 attachment, the surface of the snap-on mounting body 1 is fixed with a battery compartment 12, and a power switch 13 is installed on the side end of the snap-on mounting body 1; both the battery compartment 12 and the power switch 13 are electrically connected to the microcontroller.

[0025] As shown in the Figure 2 attachment, both the first extrusion structure 4 and the second extrusion structure 5 include a push switch installed on the surface of the snap-on mounting body 1 and an extrusion block 14 installed in the first channel 2 and the second channel 3 and in sliding contact with the push switch.

[0026] Press the pressing switch once, and the extrusion block 14 extrudes the infusion tubes located in the first channel 2 and the second channel 3, so that the infusion tubes are extruded and closed, and the liquid medicine cannot pass through; press the pressing switch again, and the extrusion block 14 releases the extrusion of the infusion tubes, so that the infusion tubes are unblocked; the structural principles of the above-mentioned pressing switch and the extrusion block 14 matching each other are all prior arts, and will not be elaborated here.

[0027] The signal sensor 6, the first signal sensor 7 and the second signal sensor 8 all include a light generator and a receiver arranged opposite to the light generator.

[0028] When light propagates in a medium, the light intensity will be weakened, and when passing through different media, the reduction value of the light intensity is different. According to this principle, considering the wall material and thickness of the infusion tube, a light intensity critical value is set. When the light emitted by the light generator passes through the infusion tube without liquid medicine, the light intensity value received by the receiver at this time is greater than the light intensity critical value, and a passing signal is sent. When the light emitted by the light generator passes through the infusion tube with liquid medicine, the light intensity value received by the receiver at this time is less than the light intensity critical value, and a blocking signal is sent.

[0029] As shown in the Figure 3 attachment, the snap-on mounting body 1 includes a first half shell 15 and a second half shell 16 that are snap-fitted together. The side end of the first half shell 15 is hinged to the corresponding side end of the second half shell 16. Snap fasteners are installed at the other side ends of the first half shell 15 and the second half shell 16 corresponding to each other, and the two snap fasteners are snap-connected together.

[0030] The structural design of the first half shell 15 and the second half shell 16 realizes the convenient and rapid installation of the snap-on mounting body 1. Open the snap fastener, and the side ends of the first half shell 15 and the second half shell 16 are released from the fixed connection. Then place the first infusion tube and the second infusion tube in the first channel 2 and the second channel 3 respectively. Then snap the two snap fasteners together to realize the fixed connection of the first half shell 15 and the second half shell 16, and complete the installation of the snap-on mounting body 1.

[0031] As shown in the Figure 3 attachment, two semi-circular grooves one are formed through the first half shell 15, and two semi-circular grooves two are formed through the second half shell 16. The semi-circular groove one and the corresponding semi-circular groove two together form the first channel 2 or the second channel 3.

[0032] A button battery is installed in the battery compartment 12.

[0033] During operation, first open the snap fasteners on the first half shell 15 and the second half shell 16, then place the first infusion tube and the second infusion tube in the first channel 2 and the second channel 3 respectively, and then snap the two snap fasteners together to complete the installation of the snap-on mounting body 1.

[0034] Then press the first extrusion structure 4 and the second extrusion structure 5. Press the switch to press the extrusion block 14, so that the liquid paths of the first infusion tube and the second infusion tube are closed. Then turn on the power switch 13. The signal sensor 6 emits a blocking signal, indicating that the liquid medicine in the first infusion tube has normally flowed above the first extrusion structure 4. Then open the first extrusion structure 4, and the liquid medicine in the first infusion tube flows down normally. The first signal sensor 7 emits a blocking signal. At this time, the second extrusion structure 5 remains closed, and the liquid path of the second infusion tube remains closed.

[0035] When the microcontroller receives the blocking signal emitted by the signal sensor 6 and at the same time receives the blocking signal emitted by the first signal sensor 7, at this time, the second signal sensor 8 emits a passing signal, and the alarm component does not emit sound and light reminders.

[0036] When the last liquid medicine in the first infusion tube flows past the first signal sensor 7, the signal sensor 6 emits a passing signal, and the first signal sensor 7 emits a passing signal.

[0037] When the microcontroller receives the passing signal emitted by the signal sensor 6 and at the same time receives the passing signal emitted by the first signal sensor 7, at this time, the second signal sensor 8 emits a passing signal, and controls the first sound and light alarm 9 to emit sound and light reminders, prompting that the liquid medicine in the first infusion tube has been transfused, and reminding the nursing worker to close the first extrusion structure 4 in time.

[0038] Then the nursing worker closes the first extrusion structure 4 and at the same time opens the second extrusion structure 5. The liquid path of the second infusion tube is opened, and the liquid medicine flows down normally. The second signal sensor 8 emits a blocking signal.

[0039] When the microcontroller receives the blocking signal emitted by the second signal sensor 8, it controls the first sound and light alarm 9 to turn off.

[0040] When the last liquid medicine in the second infusion tube flows past the second signal sensor 8, the second signal sensor 8 emits a passing signal.

[0041] When the microcontroller receives the passing signal emitted by the second signal sensor 8, it controls the second sound and light alarm 10 to emit sound and light reminders, reminding the nursing worker that the liquid medicine in the second infusion tube has been transfused and preparing for the tube removal work.

[0042] If the following error situations occur, the alarm component can also emit sound and light reminders in time:

[0043] If the liquid medicine in the first infusion tube has run out, and the second extrusion structure 5 fails to be pressed in time, and the second infusion tube fails to be opened in time, after the waiting time exceeds the set time, the microcontroller controls the first sound and light alarm 9 and the third sound and light alarm 11 to emit sound and light reminders simultaneously, strongly reminding the nursing staff to close the first extrusion structure 4; this solves the problem that the nursing staff fails to close the first infusion tube in time, resulting in air entering the inner end of the infusion tube and affecting the health of the patient.

[0044] If the liquid medicine in the first infusion tube has not run out, and the second extrusion structure 5 is wrongly pressed, causing the second infusion tube to open. At this time, the signal sensor 6 emits a blocking signal, the first signal sensor 7 emits a blocking signal, and the second signal sensor 8 emits a blocking signal. After receiving the signals, the microcontroller controls the third sound and light alarm 11 to emit sound and light reminders; this solves the problem that when both liquid paths are opened simultaneously, the mixing of two different liquid medicines may cause incompatibility and affect the health of the patient.

[0045] If the liquid medicine in the first infusion tube has run out, but after opening the second infusion tube, the first extrusion structure 4 fails to be pressed in time, and the first infusion tube fails to be closed in time, causing the liquid medicine in the second infusion tube to flow back into the first infusion tube. At this time, the second signal sensor 8 emits a blocking signal, and the first signal sensor 7 emits a blocking signal first, and the signal sensor 6 emits a blocking signal later. After receiving the signals, the microcontroller controls the third sound and light alarm 11 to emit sound and light reminders; this solves the problem that when switching, if the first infusion tube fails to be closed in time, the liquid medicine in the second infusion tube will flow back into the first infusion tube, affecting the input of the liquid medicine.
