Description

Technical Field

[0001] The present invention relates to the technical field related to medical equipment, and in particular to a heatable blood oximeter. Background Art

[0002] Blood oxygen saturation is the percentage of oxygenated hemoglobin (HbO2) capacity bound to oxygen in the blood to the total bindable hemoglobin capacity, that is, the concentration of blood oxygen in the blood. It is an important physiological parameter of respiratory circulation, and blood oxygen saturation is usually detected by a blood oximeter. The main measurement indicators of a blood oximeter are pulse rate, blood oxygen saturation, and perfusion index. Blood oxygen saturation is one of the important basic data in clinical medicine. Blood oxygen saturation refers to the percentage of O2 capacity bound to the total blood volume to the total bindable O2 capacity. However, when testing patients in winter, due to the low temperature of the patients' hands, it is inconvenient for existing blood oximeters to heat the patients' hands, which affects the detection effect. In addition, due to the large number of bacteria on the hands, cross-infection is prone to occur when testing different patients. In addition, the blood oxygen detection piece of the existing blood oximeter is usually set inside the blood oximeter, which makes it inconvenient to disassemble when damaged.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figure 1-8 The present invention provides a technical solution: a heatable oximeter, such as Figure 1 As shown, a display screen 2 is provided on the top of the detector 1, and a detection cavity 3 and a finger cleaning cavity 4 are respectively provided at the upper and lower ends of the interior of the detector 1, heating pads 6 are provided on both sides of the inner wall of the detection cavity 3, and a temperature detector 7 is provided on the top of the detection cavity 3. By arranging the heating pads 6 at both ends of the inner wall of the detection cavity 3, after the patient's finger is inserted into the detection cavity 3, the patient's detected finger can be heated, thereby improving the blood circulation of the finger, thereby improving the detection accuracy, and the temperature of the patient's finger is detected by the temperature detector 7, so that the temperature of the patient's finger can be guaranteed to be at the optimal detection temperature, and the length of the heating pad 6 can be set to the same length as the detection cavity 3, so that the detected finger can be heated in all directions to avoid the problem of local heating.

[0040] like Figure 1 As shown, a cleaning sponge 5 is provided inside the finger cleaning cavity 4, and the cleaning sponge 5 is annular. Before the test, the finger to be tested can be inserted into the finger cleaning cavity 4, so that the patient's finger can be cleaned by the cleaning sponge 5 in the finger cleaning cavity 4, which helps to improve the detection accuracy. The annular cleaning sponge 5 can be easily disassembled and assembled by pulling, so that it can be replaced after long-term use.

[0041] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, an L-shaped mounting plate 8 is arranged at the lower part of the detection cavity 3, and an arc-shaped groove 9 is provided on the upper surface of the L-shaped mounting plate 8, and a blood oxygen detection piece 10 is provided on the surface of the arc-shaped groove 9, and mounting cavities 11 are provided on both sides of the interior of the L-shaped mounting plate 8, and movable rods 12 are provided through both sides of the L-shaped mounting plate 8, and push plates 13 and movable blocks 14 are fixed at both ends of the movable rod 12, and the movable block 14 is slidably connected to the interior of the mounting cavity 11, and a spring 15 is fixed inside the mounting cavity 11, and the spring 15 is connected to the movable block 14, and limit rods 16 are provided at both ends of the side walls of the L-shaped mounting plate 8, and the limit rods 16 are connected to the movable block 14, and the same When the limit rod 16 is connected to the socket 17, the socket 17 is provided at both ends of the inside of the detector 1, and the socket 17 and the limit rod 16 are both L-shaped. By pressing the push plates 13 at both ends of the L-shaped mounting plate 8, the two sets of movable rods 12 and the movable block 14 are driven to move in the mounting cavity 11 toward one end close to the central axis of the L-shaped mounting plate 8, so that the limit rod 16 can be driven by the movable block 14 to move toward each other in the sockets 17 on both sides of the detector 1, so that the L-shaped mounting plate 8 can be pulled out of the limit rod 16 from the socket 17, and the L-shaped mounting plate 8 and the blood oxygen detection piece 10 can be disassembled, which is convenient for the inspection or replacement of the blood oxygen detection piece 10 when a fault occurs.

[0042] During installation, first align the limit rod 16 with the socket 17, and push the L-shaped mounting plate 8 to drive the limit rod 16 to move into the socket 17, then release the push plate 13, so that the movable block 14 moves to the end away from the central axis of the L-shaped mounting plate 8 under the elastic force of the spring 15, so that the limit rod 16 can be driven by the movable block 14 to move backward inside the socket 17 to engage, and the L-shaped mounting plate 8 and the blood oxygen detection piece 10 can be installed. The structure is simple and easy to disassemble and assemble, which improves convenience during use.

[0043] like Figure 7 and Figure 8 As shown, the liquid injection mechanism 18 is arranged at the rear end of the detector 1, and the liquid injection mechanism 18 includes an alcohol bottle 1801, a balloon pressurizer 1802 and a delivery tube 1803. The alcohol bottle 1801 is arranged at the rear end of the detector 1, and the balloon pressurizer 1802 is arranged on the top of the alcohol bottle 1801, and the delivery tube 1803 is arranged on the bottom of the alcohol bottle 1801. By pressing the balloon pressurizer 1802 on the top of the alcohol bottle 1801, the air is compressed so that the alcohol in the alcohol bottle 1801 is pushed by the air pressure, and the alcohol flows into the liquid guide channel 19 through the delivery tube 1803. A one-way valve is arranged on the outside of the balloon pressurizer 1802 so that after the balloon is released, it can generate negative pressure to inhale air to expand and reset. The balloon pressurizer 1802 and the alcohol bottle 1801 can be threadedly connected to facilitate disassembly and assembly to replenish alcohol in the alcohol bottle 1801.

After alcohol flows into the liquid conducting channel 19, it will flow into the finger cleaning cavity 4 and soak the cleaning sponge 5 in the finger cleaning cavity 4, so as to facilitate the sterilization and disinfection of the patient's fingers, thereby avoiding cross infection.

[0045] like Figure 7 As shown, a sealing plug 20 is provided on the outside of the finger cleaning cavity 4, and the sealing plug 20 is made of rubber. After use, the sealing plug 20 can be used to seal the finger cleaning cavity 4, so that the speed of alcohol evaporation can be reduced, thereby extending its use time.

[0046] like Figure 7 As shown, an anti-lost rope 21 is provided at the bottom of the detector 1, and the anti-lost rope 21 is connected to the sealing plug 20. By providing the anti-lost rope 21, the sealing plug 20 can be hung under the detector 1 during use, thereby preventing the smaller sealing plug 20 from being lost.

[0047] Working principle: When using the heatable oximeter, first insert the patient's finger into the finger cleaning cavity 4 for cleaning, and sterilize the finger with a cleaning sponge 5 moistened with alcohol, then insert the patient's finger into the detection cavity 3, so that the fingertip fits the blood oxygen detection sheet 10 on the surface of the L-shaped mounting plate 8 for detection. At the same time, the heating pads 6 on both sides of the detection cavity 3 can heat the patient's finger to improve the blood circulation of the finger, which is beneficial to the detection accuracy.
