Description

Technical Field

[0001] The utility model relates to the technical field of medical monitoring, in particular to a portable sleep breathing monitoring device. Background Art

[0002] Sleep quality is very important for physical and mental health. High-quality sleep can make people feel energetic and happy, while low-quality sleep may lead to fatigue, inattention, emotional problems, etc. Sleep apnea monitoring is a test method used to evaluate sleep quality and breathing conditions. It can monitor indicators such as breathing rate, blood oxygen saturation, heart rate during sleep, and help identify problems such as sleep breathing disorders.

[0003] Patent No. CN201921641644.3 proposes a portable respiratory monitor that can centrally monitor respiratory monitoring data such as human respiratory rate, respiratory pressure, temperature of exhaled gas, blood oxygen composition of exhaled gas, etc. At the same time, it can monitor the snoring of the human body during sleep through a snoring sensor. It can be used for human health monitoring and also for human sleep quality monitoring.

[0004] However, when monitoring sleep quality, it is necessary to stick a variety of sensors on the body. The connecting wires on the sensors cannot be arbitrarily changed in length according to the height, weight and size of different people. Patients are prone to entanglement when sleeping. The nasal catheter is fixed to the nose with tape, which is troublesome to remove and is easy to loosen when the patient turns over in sleep, which will make the detection data inaccurate.

DETAILED DESCRIPTION

[0026] 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.

[0027] See also Figures 1 to 6 In an embodiment of the utility model, a portable sleep breathing monitoring device includes a base plate 1 and a wire collection mechanism 5.

[0028] A monitoring host 2 is installed on one side of the top of the base plate 1 . The monitoring host 2 is a prior art product of a portable sleep breathing monitoring device, and its specific structure is not described in detail. A plurality of sensor interfaces 3 are provided on the monitoring host 2 .

[0029] There are multiple wire-taking mechanisms 5 on the base plate 1, and the wire-taking mechanisms 5 include a rotating shaft 51, a wire-taking reel 52 and a locking assembly. The rotating shaft 51 is rotatably mounted on the base plate 1 and its bottom end passes through the bottom of the base plate 1 and is provided with an adjusting button 53. The wire-taking reel 52 is located at the top of the base plate 1 and is coaxially connected to the rotating shaft 51. The locking assembly is used to limit the unidirectional rotation of the rotating shaft 51.

[0030] Furthermore, the locking assembly includes a ratchet 7, a pawl 8, a release button 9 and a tension spring 10. The release button 9 is rotatably installed at the bottom of the base plate 1 and its top end passes through the top of the base plate 1 and is connected to the pawl 8. The ratchet 7 is coaxially installed on the rotating shaft 51. A tension spring 10 is connected between the pawl 8 and the base plate 1 so that the pawl 8 abuts against the edge of the ratchet 7.

[0031] The adjusting button 53 is turned, and the adjusting button 53 drives the take-up drum 52 to rotate, so that the connecting line is wound onto the take-up drum 52, and the pawl 8 abuts against the edge of the ratchet 7 so that the ratchet 7 can only rotate in one direction, but cannot be reversed, so that the connecting line will not fall out after being taken up. By turning the release button 9, the pawl 8 can be driven to rotate away from the ratchet 7, and the tension spring 10 is stretched. At this time, the connecting line is pulled out to a suitable length, and then the release button 9 is released, and the stretched tension spring 10 is restored, so that the pawl 8 abuts against the ratchet 7 again, and the connecting line cannot be pulled out at this time.

[0032] Preferably, a protective shell 6 is slidably mounted on the other side of the top of the bottom plate 1, and the protective shell 6 can be moved close to or away from the monitoring host 2 to cover or open the wire-receiving mechanism 5, and magnets 4 are provided on the side of the monitoring host 2 and the protective shell 6 close to each other, which is beneficial to protect the wire-receiving mechanism 5 and the connecting wire.

[0033] Preferably, a strap bracket is provided at the bottom of the base plate 1, which is conducive to fixing the device on the patient's body through the strap.

[0034] Preferably, a plurality of wire clamping grooves 11 and winding rods 12 are respectively provided on the top of the base plate 1 so as to wind the connecting wires in an orderly manner.

[0035] Furthermore, it also includes a nasal catheter fixing mechanism 13, which includes a bracket 131 and a fixing strip 133. The fixing strip 133 is respectively provided with brackets 131 at both ends, and a Velcro strap 132 is connected between the two brackets 131. The monitoring host 2 is connected to a connecting tube 14, and the other end of the connecting tube 14 is connected to a nasal catheter 15, which is installed on the fixing strip 133.

[0036] Preferably, each bracket 131 is provided with a fixing frame, and the two ends of the fixing bar 133 are respectively slidably inserted into the two fixing frames. The fixing bar 133 is linearly and evenly provided with a plurality of slots, and the fixing frame is slidably provided with a pin, which can be inserted into the slot.

[0037] The bracket 131 and the fixing strip 133 are fixed to the patient's head by the Velcro strap 132, and the nasal catheter 15 is inserted into the nasal cavity. By adjusting the position of the pin on the different slots of the fixing strip 133, the fixing range of the fixing head 133 can be changed to adapt to the head sizes of different people. At the same time, the nasal catheter 15 is effectively fixed to the patient's head. Even if the patient turns over, the nasal catheter 15 is not easy to fall off.

[0038] The working principle of the utility model is:

[0039] The device is fixed to the patient's body with a strap through the strap bracket, the protective shell 6 is opened, and the sensor is connected to the sensor interface 3 of the monitoring host 2 through the connecting wire. The connecting wire is fixed to the wire clamping groove 11 and then wound onto the wire reel 52 of the wire reel mechanism 5. The winding is stopped after the connecting wire length on the patient's body surface is appropriate. The sensor is set on the patient's body surface, the protective shell 6 is closed, and the connecting wire length on the patient's body surface is appropriate, so that when the patient turns over during sleep, the wires will not be entangled or disconnected from the monitoring host 2 due to the excessive length of the connecting wire, resulting in confusion of monitoring data. When the monitoring is completed, unplug the sensor connected to the sensor interface of the monitoring host 2 3, move the connecting line out of the wire clamping slot 11, turn the adjusting button 53, and the adjusting button 53 rotates to drive the wire take-up reel 52 to rotate, so that the connecting line is quickly received in the wire take-up reel 52, and the pawl 8 abuts against the edge of the ratchet 7 so that the ratchet 7 can only rotate in one direction but not reverse, so that the connecting line will not fall out after being taken up. When the device is to be used again, the release button 9 is turned to drive the pawl 8 to rotate away from the ratchet 7, and the tension spring 10 is stretched. At this time, the connecting line is pulled out to a suitable length, and then the release button 9 is released, and the stretched tension spring 10 is restored, so that the pawl 8 abuts against the ratchet 7 again, and the connecting line cannot be pulled out at this time.

[0040] The utility model can quickly reel in the wire, and can freely change the length of the sensor connection wire according to different heights, weights and body shapes of different people, thus avoiding the entanglement of wires, and can quickly fix the nasal catheter 15 on the patient's face, and the nasal catheter 15 is not easy to loosen when the patient turns over.
