Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an intelligent instrument for oxygen inhalation monitoring. Background Art

[0002] Oxygen inhalation device is a medical device used to provide additional oxygen, usually used to treat respiratory diseases or other conditions with low blood oxygen saturation. It is mainly composed of a pressure gauge, a pressure reducing valve and a safety valve, a flow meter, a flow control valve, and a humidification bottle. High-pressure oxygen is reduced in pressure through the pressure reducing valve, and the original high-pressure oxygen is changed into low-pressure oxygen. It then enters the humidification bottle through the flow meter. After humidification, it is output from the output port at a constant flow value for the patient to inhale oxygen. The flow value is adjusted by the flow controller.

[0003] Currently, the recording of oxygen usage time relies on an oxygen usage record sheet hung by the bed, where the nurse fills in the start and end time of oxygen usage. Oxygen inhalation is charged based on the usage time (hours) in the hospitalization fee. In the event of an accidental detachment of the intermediate oxygen tube, patients and their families may question the billing and even cause disputes. A more accurate oxygen usage monitoring and timing method is needed clinically. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: an intelligent instrument for oxygen inhalation monitoring, comprising a flow meter 1, a pressure gauge 2, a humidification bottle 3, a high-pressure oxygen input end 4, a flow control valve 5 and a low-pressure oxygen output end 6, the end of the low-pressure oxygen output end 6 is connected with a measuring tube 7, an oxygen flow sensor 8 is installed on the measuring tube 7, a mounting plate 9 is fixedly connected to the top of the oxygen flow sensor 8, a timing controller 10 is fixedly connected to the top of the mounting plate 9, the timing controller 10 is connected to the oxygen flow sensor 8 signal, an oxygen absorption tube 11 is arranged at the end of the measuring tube 7, and an anti-falling mechanism is arranged on the oxygen absorption tube 11.

[0024] The timing controller 10 is also connected to the central control system signal of the nurse station, so that the nurse can monitor the patient's oxygen inhalation in real time, and can promptly alarm and notify the nurse when the patient has abnormal oxygen deprivation. When using this instrument, the high-pressure oxygen input end 4 is first connected to the oxygen outlet at the bedside, and the oxygen inhalation tube 11 is connected to the patient's mouth and nose, and the oxygen inhalation tube 11 is more firmly installed through the anti-falling mechanism, and then the oxygen inhalation tube 11 is connected to the measuring tube 7, and then the measuring tube 7 is connected to the low-pressure oxygen output end 6, and the flow control valve 5 is adjusted to make the oxygen output from the low-pressure oxygen output end 6, and the oxygen is inhaled into the lungs of the patient through the measuring tube 7 and the oxygen inhalation tube 11. During the oxygen inhalation process, the oxygen flow sensor 8 monitors the oxygen flow in the measuring tube 7 in real time, and the timing controller 10 synchronously performs timing. If the oxygen flow measured by the oxygen flow sensor 8 is lower than the set threshold value, it means that an abnormal situation has occurred. At the same time, the timing controller 10 stops timing, and after returning to normal, it will restart timing, so that the patient's oxygen inhalation time and specific oxygen inhalation amount can be accurately grasped.

[0025] Furthermore, a transparent cover 12 is movably connected to the top of the mounting plate 9 , and the transparent cover 12 covers the outside of the timing controller 10 .

[0026] See also Figure 1 , Figure 2 After setting the parameter values ​​of the timing controller 10 during use, the transparent cover 12 is clamped on the mounting plate 9 to cover the timing controller 10 to prevent irrelevant personnel from tampering with the set parameters.

[0027] Furthermore, a buzzer 13 is fixedly connected to the top of the mounting plate 9 , and the buzzer 13 is signal-connected to the timing controller 10 .

[0028] See also Figure 2 When the oxygen flow rate measured by the oxygen flow sensor 8 is lower than the set threshold, the timing controller 10 controls the buzzer 13 to alarm after receiving the signal to remind personnel to pay attention.

[0029] Furthermore, the anti-falling mechanism includes two connecting belts 14 slidably connected to the outer wall of the oxygen absorption tube 11, a fixing belt 15 is arranged between the two connecting belts 14, one end of the fixing belt 15 is fixedly connected to one of the connecting belts 14, and a connecting piece is arranged between the other end and the other connecting belt 14.

[0030] See also Figure 3 When in use, first insert the tube at the mouth and nose of the oxygen tube 11 into the patient's nostrils, then pass the oxygen tube 11 around the patient's two ears and hang it in front of the patient's chest, then tighten the oxygen tube 11 to fix it on the patient's face, then move the two connecting belts 14 to be respectively placed at the patient's two ears, then pass the fixing belt 15 behind the patient's head, and connect the fixing belt 15 and the connecting belt 14 together through the connecting piece, which can prevent some patients from not cooperating with oxygen inhalation when they are unconscious, causing the oxygen tube 11 to fall off abnormally.

[0031] Furthermore, the connecting piece includes a locking cylinder 16 fixedly connected to the end of the fixing belt 15, a steel nail 17 is fixedly connected to the connecting belt 14, the steel nail 17 slides inside the locking cylinder 16, the interior of the locking cylinder 16 is configured with a device groove 18, the end wall of the device groove 18 is fixedly connected to a spring 19, the other end of the spring 19 is fixedly connected to an iron ring 20, the iron ring 20 slides outside the steel nail 17, and two steel balls 21 are arranged inside the device groove 18, and the steel balls 21 are located on the side of the iron ring 20 away from the spring 19.

[0032] See also Figure 3 , Figure 4When in use, first insert the steel nail 17 into the device groove 18 in the locking cylinder 16, and then the iron ring 20 moves to the side close to the steel nail 17 under the elastic force of the spring 19, and drives the steel ball 21 to move until the steel ball 21 clamps and fixes the steel nail 17. When disassembling, the nurse can hold a strong magnet against the end of the locking cylinder 16 away from the steel nail 17. Under the action of magnetic attraction, the iron ring 20 moves toward the strong magnet and compresses the spring 19. At this time, the steel ball 21 loses its restriction and can roll in the device groove 18, thereby sliding the steel nail 17 out of the locking cylinder 16. This can prevent irrelevant personnel from removing the oxygen tube 11 at will, and can also prevent the oxygen tube 11 from falling off when the patient struggles.

[0033] Furthermore, one end of the device groove 18 away from the spring 19 is configured to be arc-shaped.

[0034] See also Figure 4 , the moving range of the steel ball 21 can be limited so that it clamps the steel nail 17.

[0035] Furthermore, a groove 22 is configured on the outside of the steel nail 17 at a position corresponding to the steel ball 21 .

[0036] See also Figure 4 When the steel ball 21 moves to a certain position under the push of the iron ring 20, the steel ball 21 is stuck in the groove 22 outside the steel nail 17. In this way, even if the steel nail 17 is pulled back and forth, the steel nail 17 will not slip out of the locking tube 16, and can be clamped more tightly.

[0037] Furthermore, the connecting belt 14 is made of a relatively soft material.

[0038] See also Figure 3 In this way, when the connecting belt 14 is pulled, no pain will be generated at the position where the skin of the ear is in contact with the connecting belt 14.

[0039] Working principle: When the intelligent instrument for oxygen inhalation monitoring is used, the high-pressure oxygen input terminal 4 is first connected to the oxygen outlet at the head of the bed, and then the tube at the mouth and nose of the oxygen inhalation tube 11 is inserted into the patient's nostrils, and the oxygen inhalation tube 11 is passed around the two ears of the patient and hung in front of the patient's chest, and then the oxygen inhalation tube 11 is tightened to fix it on the patient's face, and then the two connecting belts 14 are moved so that they are respectively placed at the two ears of the patient, and then the fixing belt 15 is passed around the back of the patient's head, and the steel nail 17 is inserted into the device groove 18 in the locking cylinder 16, and then the iron ring 20 moves to the side close to the steel nail 17 under the elastic force of the spring 19, and drives the steel ball 21 to move until the steel ball 21 is stuck in the groove 22 outside the steel nail 17, and the ends of the fixing belt 15 and the connecting belt 14 are connected together.

[0040] Then connect the oxygen inhalation tube 11 with the measuring tube 7, and then connect the measuring tube 7 to the low-pressure oxygen output end 6, adjust the flow control valve 5, so that oxygen is output from the low-pressure oxygen output end 6, and is inhaled into the lungs of the patient through the measuring tube 7 and the oxygen inhalation tube 11. During the oxygen inhalation process, the oxygen flow sensor 8 monitors the oxygen flow in the measuring tube 7 in real time, and the timing controller 10 performs timing synchronously. If the oxygen flow measured by the oxygen flow sensor 8 is lower than the set threshold, it means that an abnormal situation has occurred. The oxygen flow sensor 8 transmits a signal to the timing controller 10, and the timing controller 10 stops timing and controls the buzzer 13 to sound an alarm, or transmits a signal to the central control system of the nurse station and sounds an alarm. After returning to normal, the timing is restarted. In this way, the patient's oxygen inhalation time and the specific oxygen inhalation amount can be accurately grasped.

At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.
