Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a blood oxygen detector. Background Technology

[0002] Blood oxygen saturation refers to the proportion of oxygen-saturated hemoglobin in flowing blood. Currently, the mainstream detection method is an external sensor, which uses light phenomena to measure blood oxygen saturation in real time. The most commonly used method in clinical practice is the finger-type blood oxygen probe, which is worn on the finger and uses red light and near-infrared light as emission sources. The intensity of light transmission through the finger is measured to calculate the hemoglobin concentration and blood oxygen saturation in the blood.

[0003] Existing technologies, such as the utility model patent CN219439129U which discloses a blood oxygen detector, include a signal acquisition device for acquiring blood oxygen signals; a probe with an acquisition cavity and a vent; an air bladder disposed on the inner wall of the acquisition cavity and arranged in a closed loop; the signal acquisition device disposed on the surface of the air bladder; an air pump disposed inside the probe and outside the acquisition cavity; the air pump is connected to both the air bladder and the vent; a pressure detection device disposed on the surface of the air bladder; and a control device disposed inside the probe and outside the acquisition cavity. The control device is connected to both the air pump and the pressure detection device and is used to acquire data collected by the pressure detection device and control the inflation and deflation of the air pump. Because the air bladder has good contractile characteristics, it can change volume in both inflated and deflated states, satisfying the wearing applicability of different sized fingers of infants and adults while reducing wearing discomfort.

[0004] The device is suitable for wearing on fingers of different sizes, including those of infants and adults. However, the inner wall of the collection chamber is inconvenient to clean, and the residue of skin flakes can easily lead to bacterial growth, affecting the safety of use.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0010] The air outlet of the air pump is fixedly connected to the ventilation box, and the ventilation box is connected to the airbag through a pipe passing through the partition plate; the two arc-shaped plates contact each other and form a cylindrical shape.

[0011] Furthermore, the airbag is located inside the arc-shaped plate, which is fixedly mounted on the housing and the mounting cover, respectively.

[0012] Furthermore, an anti-slip sleeve is movably installed on the inner wall of the airbag, and the anti-slip sleeve is divided into an upper anti-slip sleeve and a lower anti-slip sleeve.

[0013] Furthermore, one end of the upper anti-slip sleeve is fixed to the edge of the semi-circular groove on the mounting cover, and the other end is fixedly connected to the sliding block.

[0014] Furthermore, the sliding block is semi-circular and is slidably installed in a semi-circular hole in the partition plate.

[0027] like Figures 1 to 6 As shown, the pulse oximeter of this utility model includes: a housing 1, a mounting cover 2, and a fixing mechanism to prevent it from falling off.

[0028] A partition plate is fixedly installed inside the housing 1, and a semi-circular hole is provided on the partition plate. The housing 1 and the semi-circular groove on the mounting cover 2 form a detection port 4. A positioning rod 6 is symmetrically fixedly installed on the partition plate, and a positioning block 9 aligned with the positioning rod 6 is fixedly installed on the mounting cover 2. The positioning rod 6 is slidably installed in the positioning hole on the positioning block 9. A fixing block 7 is fixedly installed on the partition plate, and a fixing hole is provided on the fixing block 7. A fixing rod 21 is slidably installed in the fixing hole, and the fixing rod 21 is fixedly installed on the mounting cover 2. The mounting cover 2, the fixing block 7, and the fixing rod 21 are provided with aligned threaded holes 20. A fixing bolt 8 is threaded into the threaded hole 20.

[0029] The fixing mechanism includes: an airbag 5, an arc-shaped plate 10, and an air pump 13; the air pump 13 is fixedly installed inside the housing 1, and the air inlet of the air pump 13 passes through the inner wall of the housing 1; the air outlet of the air pump 13 is fixedly connected to a ventilation box 14, and the ventilation box 14 is connected to the airbag 5 through a pipe passing through a partition plate; a filter screen is fixedly installed at the air inlet of the air pump 13 to filter dust in the inhaled air; the two arc-shaped plates 10 contact each other and form a cylindrical shape; the airbag 5 is located inside the arc-shaped plates 10, and the arc-shaped plates 10 are respectively fixedly installed on the... The housing 1 and the mounting cover 2 are described; the position of the arc-shaped plate 10 is fixed to limit the expansion direction of the airbag 5; an anti-slip sleeve 11 is movably installed on the inner wall of the airbag 5, the anti-slip sleeve 11 is divided into an upper anti-slip sleeve and a lower anti-slip sleeve, so that the inner wall of the anti-slip sleeve 11 is easy to clean; one end of the upper anti-slip sleeve is fixed to the edge of the semi-circular groove on the mounting cover 2, and the other end is fixedly connected to the sliding block 12; the sliding block 12 is semi-circular and is slidably installed in the semi-circular hole on the partition plate; the two ends of the lower anti-slip sleeve are respectively fixedly connected to the inner wall of the housing 1 and the partition plate.

[0030] After use, the mounting shell can be removed, which moves the upper anti-slip sleeve and an arc-shaped plate 10 apart, facilitating the cleaning of the inner walls of the upper and lower anti-slip sleeves. This prevents skin residue from causing bacterial growth and improves the safety of use. In the existing technology, the airbag 5 and anti-slip sleeve 11 are used to accommodate the different finger sizes of infants and adults. Skin residue in the anti-slip sleeve 11 can easily lead to bacterial growth, posing a safety hazard to the pulse oximeter during repeated use. Clip-on pulse oximeters can also affect blood flow to the fingers when held for extended periods. Therefore, by dividing the anti-slip sleeve 11 into two parts, located on the mounting cover 2 and the housing 1 respectively, the pulse oximeter can be disassembled, facilitating the cleaning of the inner wall of the anti-slip sleeve 11 and improving the safety of the pulse oximeter during repeated use.

[0032] Working principle:

[0033] After use, by tightening the fixing bolt 8, the bottom of the fixing bolt 8 is disengaged from the threaded hole 20 on the fixing rod 21, and the mounting cover 2 is removed from the housing 1. The mounting cover 2 causes the positioning block 9 to separate from the positioning rod 6, and the upper anti-slip sleeve causes the sliding block 12 to disengage from the semi-circular hole on the partition plate, so that the inner wall of the upper anti-slip sleeve can be directly cleaned. The air in the airbag 5 is discharged by the air pump 13, which makes it easy to adjust the coverage position of the airbag 5, so that there are no obstructions on the inner wall of the lower anti-slip sleeve, which makes it easy to clean the inner wall of the anti-slip sleeve 11 and improves the safety of the pulse oximeter during repeated use.
