Description

Technical Field

[0001] The invention relates to the technical field of monitor verification, in particular to an online verification device for the non-invasive blood pressure part of a multi-parameter monitor. Background Art

[0002] Multi-parameter monitors are essential for some patients. They can monitor a variety of patient parameters in real time, such as ECG signals, heart rate, blood oxygen saturation, blood pressure, respiratory rate, and body temperature. However, due to the need for regular inspections, some patients need to regularly remove their multi-parameter monitors, including the invasive monitoring part of the multi-parameter monitors, which has an impact on the patients.

[0003] Therefore, there are currently online verification devices to solve this problem;

[0004] For example, the Chinese patent with publication number CN210533603U discloses an online calibration system for the non-invasive blood pressure part of a multi-parameter monitor, including a ward and a calibration room, a main airway pipeline is buried in the wall of the ward and the calibration room, a branch airway tube is fixed in the adapter, the free end of the branch airway tube is connected to the non-invasive blood pressure port of the multi-parameter monitor, and the other end extends into the wall and is connected to the main airway pipeline; an airway on-off switch is installed on the branch airway tube, a pressure sensor 1 is installed inside, a pressure sensor 2 is installed in the main airway pipeline, and the detection end of the calibration equipment is connected to the main airway pipeline; The utility model establishes an online calibration system for the non-invasive blood pressure part of the multi-parameter monitor, and can remotely calibrate the multi-parameter monitor one by one by controlling the gas circuit on-off switch, thereby avoiding the removal of the multi-parameter monitor. While ensuring regular calibration, it does not affect the normal use of the patients, bringing great convenience to the patients. The adapter provides buffering protection for the branch trachea. However, in reality, the calibration room is often far away from the ward, and the use of gas circuit pipelines for connection often increases the overall detection time due to the long pipeline, and reduces the detection accuracy, which makes the calibration effect impossible.

DETAILED DESCRIPTION

[0032] Example: See Figures 1 to 7In an embodiment of the present invention, an online calibration device for the non-invasive blood pressure part of a multi-parameter monitor is used to calibrate the non-invasive blood pressure parts of multiple multi-parameter monitors 12 one by one. The multi-parameter monitors 12 are placed in a ward 1.

[0033] Multiple multi-parameter monitors can be placed in each ward 1. When performing online calibration, the device can calibrate them one by one according to the order of the wards 1, and can also calibrate the multi-parameter monitors one by one in each ward 1 according to the order of the multi-parameter monitors;

[0034] The non-invasive blood pressure detection end of the multi-parameter monitor 12 is connected to the three-way pipe 10 by a straight-connecting pipe 11, and the three-way pipe 10 is also connected to a hose 1 and a connecting pipe 9, wherein the other end of the hose 1 is connected to a cuff 13, and the connecting pipe 9 is fixed upward through the partition 2 of the ward 1 and is connected to a sealing joint 8;

[0035] When the multi-parameter monitor is not being calibrated, the connecting tube 9 is in a closed state, thereby ensuring that the non-invasive blood pressure detection end of the multi-parameter monitor 12 can normally monitor the patient's blood pressure;

[0036] The connecting pipe 9 is further configured to be fixed upward through the partition 2 of the ward 1 and connected with the sealing joint 8, so that when the multi-parameter monitor is calibrated, it is only necessary to move the calibrator to the corresponding position and connect the sealing joint;

[0037] The tester 6 can be pre-adjusted to operate in an automatic detection and calibration mode;

[0038] After the calibrator 6 calibrates a multi-parameter monitor each time, it waits for the connection to the next multi-parameter monitor and restarts its detection program, which will not be described in detail here.

[0039] A track assembly 4 is arranged between the ceiling and the partition 2 of the ward 1, and a mobile vehicle 5 is movably arranged on the track assembly 4. The mobile vehicle 5 carries a calibrator 6, and the calibrator 6 has a calibration connector 7. The calibration connector 7 can be connected to the sealing connector 8, so as to calibrate the non-invasive blood pressure part of the multi-parameter monitor 12.

[0040] In order to ensure that the calibration instrument 6 on the mobile vehicle 5 can calibrate multiple multi-parameter monitors 12 in the same ward 1, the track assembly 4 is set as follows: Figure 4 and 5The track assembly 4 includes two main tracks 41 symmetrically erected in the ward 1, the main track 41 is located between the partition 2 and the top plate 3, the main track 41 is divided into multiple sections, and a secondary track 42 is arranged between two adjacent sections. The two secondary tracks 42 are fixed by a fixing rod 3, and the secondary track 42 is also limitedly slidably arranged on a support plate 44, the support plate 44 is perpendicular to the main track 41, and is located at the bottom of the main track 41, and a powered lead screw 45 is rotatably arranged on the support plate 44, and the lead screw 45 is transmission-connected to the secondary track 42.

[0041] It should be noted that the auxiliary rail 42 here is pre-drilled with threads matching the lead screw 45, so it can be connected to the lead screw 45 in transmission. Of course, a nut seat can also be embedded in the auxiliary rail 42 and connected to the lead screw 45 in transmission through the nut seat.

[0042] When the lead screw 45 rotates, it can drive the auxiliary track 42 to move, so that the auxiliary track 42 can move laterally in a certain ward, thereby facilitating the calibration instrument 6 to sequentially calibrate multiple multi-parameter monitors 12 in a certain ward.

[0043] In this embodiment, Figure 1 and 2 A control valve is also provided on the connecting pipe 9. The control valve is arranged near the three-way pipe 10. When the control valve is powered off, the connecting pipe 9 can be blocked. When the inspection joint 7 is connected to the sealing joint 8, the inspection joint 7 can also supply power to the control valve through the wire 15, thereby releasing the blocking of the connecting pipe 9 by the control valve.

[0044] That is to say, when the multi-parameter monitor 12 is not calibrated, the control valve is not energized. At this time, it can block the connecting tube 9, thereby ensuring that the non-invasive blood pressure part of the multi-parameter monitor can monitor the patient's blood pressure normally. When the control valve is energized, the control valve can contact the blockage of the connecting tube 9.

[0045] For details, please refer to Figure 3 , Figure 3 The actual Figure 7AA sectional view, the control valve includes an electromagnetic seat 16, which is powered by a wire 15, and the electromagnetic seat 16 is connected to the inner wall of the connecting pipe 9 by multiple limit strips 17 on all sides, and the limit strips 17 are slidably connected to a slide seat 19 on the upper limit position, and a return spring 20 is also connected between the slide seat 19 and the electromagnetic seat 16, and a retractable elastic sealing slide plate 18 is connected between the outer tops of two adjacent slide seats 19, and the middle part of the elastic sealing slide plate 18 is fixed to the inner wall of the connecting pipe 9, and multiple elastic sealing slide plates 18 are commonly connected to a sealing film; multiple electromagnets are embedded in the electromagnetic seat 16, and magnetic blocks are correspondingly embedded in the slide seat 19.

[0046] Among them, when the electromagnet is powered off, the slide 19 slides to the inner wall of the connecting tube 9 under the action of the return spring 20, and multiple elastic sealing slides 18 and sealing films can seal the connecting tube 9. When the electromagnet is powered on, the magnetic block in the slide 19 is attracted by the electromagnet, thereby driving the slide 19 to move in direction 16 close to the electromagnet. At this time, the elastic sealing slide 18 is bent, thereby releasing the blockage of the connecting tube 9.

[0047] As a preferred embodiment, a sealing gasket is fixed on a surface of one side of the elastic sealing slide plate 18 close to the connecting pipe 9 .

[0048] In this embodiment, Figure 2 The middle part of the mobile vehicle 5 is embedded with the calibration instrument 6, and the calibration end of the calibration instrument 6 is connected with the calibration connector 7 by a hose 2. The bottom of the mobile vehicle 5 is also connected with the calibration connector 7 by a telescopic rod 14. It should be noted that the sealing connector 8 and the calibration connector 7 are both arranged vertically to ensure that the two can be quickly sealed and connected.

[0049] In this embodiment, Figure 6 The test joint 7 comprises a test joint body 71, an upper sealing ring 73 and a ring sleeve 74, wherein the upper end of the test joint body 71 is connected to the test end of the test instrument 6, and an annular inner step groove 72 is provided on the inner side of the lower end of the test joint body 71, and the outer part of the test joint body 71 is fixedly sleeved with an upper sealing ring 73 and a ring sleeve 74 in sequence;

[0050] Four deflection rods 76 are symmetrically hinged in the middle of the verification joint body 71 , and the other ends of the deflection rods 76 are hinged to the power supply head 75 .

[0051] Correspondingly, Figure 7The sealing joint 8 includes a sealing joint body 81, a lower sealing ring 83 and an electrical connector 84, wherein an annular outer step groove 82 corresponding to the inner step groove 72 is opened on the top outer side of the sealing joint body 81, and the outer step groove 82 can be embedded in the inner step groove 72. A lower sealing ring 83 corresponding to the upper sealing ring 73 is fixed to the outside of the sealing joint body 82, and an electrical connector 84 is fixed to the middle of the sealing joint body 82, and the electrical connector 84 supplies power to the control valve through the wire 15.

[0052] In addition, the annular sleeve 74 can wrap the sealing joint 8 , and the bottom of the upper sealing ring 73 is higher than the top of the inner stepped groove 72 .

[0053] When the test joint 7 is sealed and connected to the sealing joint 8, the inner step groove 72 is just sleeved on the outside of the outer step groove 82, the bottom of the upper sealing ring 73 is in close contact with the top of the lower sealing ring 83, and the ring sleeve 74 is sleeved on the outside of the upper sealing ring 73 and the lower sealing ring 83.

[0054] At the same time, the power supply head 75 can contact the power connection head 84. In order to reserve installation errors, four deflection rods 76 are symmetrically hinged in the middle of the calibration joint body 71. The other end of the deflection rod 76 is hinged to the power supply head 75, and the deflection rod 76 has a certain degree of elasticity.
