[0016] 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.

[0017] Example: See Figure 1-Figure 4 The utility model provides a spontaneous breathing detector, comprising a chest strap 1, a measuring tape 2 and a pressure sensor 7. The head end of the chest strap 1 is fixedly connected to the head end of the measuring tape 2, a ring belt 3 is fixedly connected to the chest strap 1, the tail end of the measuring tape 2 passes through the ring belt 3, and the tail end of the measuring tape 2 is connected to the tail end of the chest strap 1 through a nylon buckle 4.

[0018] The head end of the measuring tape 2 is its zero scale point. With the loop 3 as a reference, the length of the tail end of the measuring tape 2 passing through the loop 3 can be determined, thereby determining the actual length of the circle formed by the chest strap 1 and the measuring tape 2. The subject exhales the air in the body, and wears the chest strap 1 and the measuring tape 2 in a circle on the chest, recording the length of the tail end of the measuring tape 2 passing through the loop 3 before breathing, and then releases the Velcro 4 between the measuring tape 2 and the chest strap 1. After inhaling, the tail end of the measuring tape 2 passes through the loop 3 again, and the chest strap 1 and the measuring tape 2 are tightened, and the length of the tail end of the measuring tape 2 passing through the loop 3 after inhalation is recorded. The difference between the lengths before and after breathing is the degree of chest expansion.

[0019] The chest strap 1 is movably sleeved with a sliding member 5, the rear side wall of the sliding member 5 is fixedly connected to a base 6, the rear side wall of the base 6 is fixedly connected to a pressure sensor 7, and the upper side wall of the base 6 is fixedly connected to a digital display 8 electrically connected to the pressure sensor 7. A power module electrically connected to the pressure sensor 7 and the digital display 8 is fixedly provided in the base 6, and the side wall of the base 6 is fixedly provided with a charging interface electrically connected to the power module, and the output end of the pressure sensor 7 is electrically connected to the input end of the digital display 8. The pressure sensor 7 is a micro resistive strain pressure sensor, and the power module is a lithium battery.

[0020] The pressure sensor 7 is attached to the chest of the test subject. When the test subject breathes, each breath will produce pressure on the pressure sensor 7. The pressure sensor 7 outputs the pressure change it detects as a voltage change signal and transmits it to the digital display 8. The digital display 8 counts according to each voltage change signal, with 1 minute as the unit time. By observing the digital changes on the digital display 8 within 1 minute, the number of breaths of the test subject within 1 minute can be obtained.

[0021] On the basis of the above-mentioned embodiment, in this embodiment, the sliding member 5 is provided with a through hole 501 for allowing the chest strap 1 to pass through, and an inverted V-shaped surface 502 is formed on the sliding member 5 and in the through hole 501, and the inverted V-shaped surface 502 is located on the rear side of the chest strap 1, and two inclined blocks 9 that are slidably abutted against the front side wall of the chest strap 1 are provided in the through hole 501, and the inclined surfaces of the two inclined blocks 9 are respectively slidably abutted against the two inclined surfaces of the inverted V-shaped surface 502, and a spring 10 is fixed between the two inclined blocks 9, and the two ends of the spring 10 are respectively welded to the two inclined blocks 9, and a push block 11 is integrally formed on the opposite end surfaces of the two inclined blocks 9 and located outside the sliding member 5.

[0022] In this embodiment, the spring 10 is in a compressed state, and the spring 10 pushes the two inclined blocks 9 apart, so that the inclined blocks 9 are tightly fitted to the chest strap 1 and the inverted V-shaped surface 502. The friction generated by the inclined blocks 9, the chest strap 1 and the inverted V-shaped surface 502 allows the slider 5 to be fixed on the chest strap 1. When both hands squeeze the two push blocks 11 at the same time, the two inclined blocks 9 can be separated from the chest strap 1 along the inverted V-shaped surface 502, so that the slider 5 can move on the chest strap 1, which facilitates the adjustment of the position of the slider 5, so that the pressure sensor 7 remains in proper fit with the chest of the test subject.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
