However, the drawings are only for reference and explanation, and are not intended to be used for the present invention. limit. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. As shown in FIG. 1, it is a preferred embodiment of the negative pressure suction air pressure measuring device of the present invention. The negative pressure suction air force measuring device is applied to the snoring system, and is mainly used for measuring patient suction. The gas pressure value at the time of gas.囫, Figure 2 and Figure 3, the negative pressure suction air pressure measuring device 1 〇 (B 3 gas pipe!, a spring 2 placed in the gas pipe i, and a 嗖 indicator placed in the gas pipe i 3. The gas pipe is transparent, comprising: a pipe body 11, and a cover 13 for being sleeved at one end of the pipe body u, defining a gas flow path U1, and a first opening for making the gas two-two: 112, and the cover 13 defines a gas-cut phase end of the first two-pipe body and the door gas flow passage 111 communicates with the outside, and is connected to the patient y mask through a gas-cutting tube (not shown). Thereby, the gas outside the 201106922 air pressure measuring device 100 flows into the gas flow path 111 from the second opening 131, and flows out to the gas cutting pipe or the three-way pipe through the first opening 112. The first pipe portion 110 of the pipe body 11 is outside. The second tube portion 113 is disposed adjacent to the first opening 112. The second tube portion 113 defines a through hole 114 communicating with the gas flow path ηι and located between the first and second openings 112 and 131. The design of the hole 114 'when the patient is exhaling, most of the gas flowing into the gas flow path 111 through the first opening H2 can pass through The hole 114 is discharged to the outside, and a very small portion of the gas is discharged to the outside through the second opening 13 1. Further, the first pipe portion 11 defines an inner surface 115 of the gas flow path 111 which is provided adjacent to the first opening 112. The first card slot ι16, and the second tube portion 113 defines an inner surface 117 of the through hole 114 is provided with a second card slot 118, and the negative pressure suction air force measuring device 1 〇〇 further includes a card in the first card slot a first flap 4' of 116 and a second flap 5 stuck to the second slot 118, the first and second flaps 4, 5 are respectively made of paper for gas circulation, by 1. The design of the second striker 4, 5 can block the body fluid accompanying the gas flow when the patient exhales the gas, so as to prevent the patient's body fluid from flowing out through the second opening 131 or the through hole 114 to the caregiver. The spring 2 is a metal. a compression spring of the material, which is disposed in the gas flow passage iu and includes a fixed end 2 and a free end 22 at the opposite end of the fixed end 21, and the fixed end 21 of the spring 2 is used to engage the inner surface of the first tube portion 11 On a ring-shaped positioning member U9, the free end 22 of the spring 2 is adjacent to the second opening 131 and is in the form of a disc The indicator member 3 is connected, and the free end 22 is sleeved on the convex portion 31 of the indicator member 3.

Due to the blocking of the pressure receiving surface 32 of the fingering of the 201106922, most of the gas is applied to the pressure receiving surface 32. Pulling up the indicator 3 to move toward the first opening 112 and compressing the spring 2' while a small portion of the gas flows through the gap between the outer circumference of the indicator 3 and the inner surface 115 of the first tube portion, and The first opening 112 flows. In step 73, the viewing indicator 3 knows the magnitude of the measured pressure value corresponding to the position of a scale 120 on the gas pipe. The caregiver can view the position of the indication portion 33 of the indication member 3 corresponding to a measured pressure value in the scale unit 12A from the tube body of the gas delivery tube, and the magnitude of the pressure value is obtained through the scale unit 120. Furthermore, by the position of one of the color marking areas 121, 122 123 corresponding to the indicating portion 33, it can be quickly and surely determined whether the inspiratory pressure of the patient during inhalation is sufficient, and when the indicating portion 33 corresponds to the color indicating area 123 At the time, it means that the patient has sufficient inspiratory pressure and has the ability to breathe spontaneously. At this time, the caregiver can take the patient out of the respiratory system. If the indication portion 33 corresponds to the color indication area ΐ2ι, 122, it means that the patient still has to rely on the respiratory system to maintain the breathing operation. When the patient exhales, the caregiver can move the finger 6 away from the through hole to discharge part of the gas hole, and the indicator 3 can quickly return to the cover body by the gas of another part and the return elastic force of the spring 2. 13" Abutment I" position. It should be noted that the negative pressure suction air pressure measuring device 1〇〇 of the air pipe i can also be designed as shown in Fig. 7 only the first block 4, or As shown in Fig. 8, the second flap 5' can also be used to block the effect of the body fluid accompanying the gas flow when the patient exhales the gas, and is not disclosed in the first embodiment. The manner of the flaps 4, 5 is limited. 10 201106922 In summary, the negative pressure suction air pressure measuring device in the present embodiment can save manufacturing man-hours and reduce manufacturing due to simple design and small size. The cost, and by the indication portion 33 of the indicator member 3 corresponding to the position of the scale unit 120 on the gas pipe! and the position of the position of the color indication regions 121, 122, 123, enables the caregiver to quickly and surely know that the patient is sucking Gas pressure during gas, so it is true The above is the object of the present invention. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the scope of the patent application and the description of the invention are generally BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a preferred embodiment of a vacuum suction force measuring device of the present invention; FIG. 2 is a view of a preferred embodiment of the present invention.
