The mounting tube 2 is used for mounting various valves. The above-mentioned basic operation flow for breathing the leather bag, not specifically not being described in detail, installation methods and detail structure of spare parts such as duckbill valve 4, expiratory valve 5, relief valve 3 are also not described in detail, are prior art.

The treatment piece 6 has been add in the breathing leather bag in this scheme, presses sacculus 1 back, and oxygen passes through air passage one 5a and air passage two 6b, and under the effect of oxygen, the treatment medicine in the casing 6a gets into the piece of ventilating along the air current to the effect respiratory track makes asthma symptom obtain alleviating fast, and the piece of ventilating plays the effect of the conduction of ventilating here. The scheme utilizes the extrusion power to send therapeutic drugs into the respiratory tract of a patient, simulates the mouth inhalation operation of the patient through a reverse injection mode, realizes a non-venous treatment mode, greatly improves the treatment safety, reduces the visceral load of a human body, and reduces adverse reactions. Meanwhile, the oxygen power is sufficient due to the external force injection mode, the medicine moves rapidly, and compared with active inhalation, the medicine can directly reach the respiratory tract rapidly and takes effect rapidly. In addition, the basic function of the breathing leather bag is fully utilized, oxygen is supplied to the patient, the patient is helped to quickly recover normal breathing, and the concept is novel and ingenious.

In particular, the vent is a mask. When the ventilation piece is a mask, the mask is in inserted connection or tight fit with the shell 6a and can be detached at any time. The respiration leather bag in the scheme has two functions of oxygen supply and treatment, and the oxygen supply function is not described any more and is a basic function.

As shown in fig. 9, the present embodiment is different from the embodiment in that the puncturing structure includes a through hole 6c opened on the housing 6a, the through hole 6c penetrates to the capsule 7, and the outer end of the through hole 6c is blocked by a stud 9. In this solution, the piercing is performed by an external tool by unscrewing the stud 9, piercing the capsule 7 with a sharp object, and then resetting the stud 9, which reduces the complexity of the treatment member 6 and simplifies the structure.

EXAMPLE III

As shown in fig. 10 to 12, the respiration bag comprises a balloon 1, a mounting tube 2, a safety valve 3, a duckbill valve 4, an exhalation valve 5 and an air vent, wherein one end of the mounting tube 2 is connected to one end of the balloon 1, the safety valve 3, the duckbill valve 4 and the exhalation valve 5 are connected to the mounting tube 2, a first air passage 5a is arranged in the exhalation valve 5, a second treatment piece 12 is further included, a treatment medicine is arranged in the second treatment piece 12, when the one-way valve flap 4a of the duckbill valve 4 is opened, the second treatment piece 12 is broken, the treatment medicine leaks from the second treatment piece 12 and enters the first air passage 5a, and the first air passage 5a is communicated with the air vent. In the scheme, the second treatment piece 12 replaces the first treatment piece. When the sacculus 1 is squeezed, the oxygen acts on the duckbill valve 4 to open the one-way valve clack 4a, the one-way valve clack 4a is opened to move outwards, the process can touch the second treatment piece 12, the second treatment piece 12 is broken under the action of impulsive force to form a leakage channel, the treatment medicine leaks from the leakage channel to enter the first air channel 5a and then enters the air passing piece, and finally enters the respiratory tract of the human body to play a role. The second therapeutic piece 12 is extruded by the aid of impulsive force generated when the one-way valve clack 4a is opened, so that medicine in the therapeutic piece can flow out, the existing structure is fully utilized, and the novel therapeutic piece is ingenious in structural design and simple in structure. The ventilation piece can be a mask or a trachea cannula and the like, and the ventilation piece and the trachea cannula are directly connected with a breather valve, which is not described in detail and is the prior art.

Specifically, the second therapeutic member 12 includes a circular capsule 12a with a cavity inside, the capsule 12a has a protrusion 12b protruding outwards and having a cavity inside, the protrusion 12b is separated from the capsule 12a by a diaphragm 12c, and the protrusion 12b is provided with a flow hole 12b 1. The therapeutic drug is filled in the capsule body 12a, the therapeutic drug is preferably powder, the therapeutic drug does not fill the inner cavity of the capsule body 12a, and a small part of gap is reserved for the action of the impact force. When the one-way valve flap 4a presses the capsule body 12a, the pressing force breaks the diaphragm 12c, the therapeutic drug enters the convex body 12b and finally flows out of the flow hole 12b1, and the convex body 12b is arranged downwards generally, so that the therapeutic drug can flow out smoothly. The setting of convex body 12b plays the transition effect, can prevent that treatment medicine from directly spilling from diaphragm 12c breach, can lead to the velocity of flow fast like this, and the medicine is extravagant, has the excessive risk of using medicine simultaneously. After the diaphragm 12c is broken, the medicine enters the convex body 12b, the therapeutic medicine flows out through the flow hole 12b1 with smaller aperture, the flow rate is limited, the medicine waste is reduced, and the structural design is ingenious. Membrane 12c has a wall thickness less than the wall thickness of bladder 12 a. This dimensioning allows the one-way flap 4a to break the membrane 12c smoothly when it presses against the capsule 12 a. The second treatment member 12 is made of nylon, and the thickness of the diaphragm 12c is not more than 0.5 mm. This dimensioning enables the impact force of the check valve flap 4a to smoothly blow away the diaphragm 12 c. An annular embedded groove 5c is formed in the inner end inner wall of the expiratory valve 5, and a part of the bag body 12a is embedded into the embedded groove 5 c. The second therapeutic piece 12 is disposable, and the capsule body 12a is clamped into the embedded groove 5c during installation.
