Description

Technical Field

[0001] The present invention belongs to the field of instruments and relates to breathing bags. This application is a divisional application of the patent application with application number 2020114638691, filed on December 14, 2020, and the invention name is "Breathing Bag". Background Art

[0002] Asthma is a heterogeneous disease. This chronic inflammation is associated with airway hyperresponsiveness, often manifesting as widespread and variable reversible expiratory airflow limitation, leading to recurrent episodes of wheezing, shortness of breath, chest tightness, and / or coughing, which vary in intensity over time. Asthma attacks often occur and worsen at night and / or in the early morning. When asthma attacks are mild, patients can use inhaled medications such as Seretide and Symbicort to control their asthma. However, when the condition is severe and the patient is unconscious during an attack, they are unable to take medications on their own. The current treatment for these conditions is direct intravenous administration of medication. While effective, long-term intravenous administration can damage blood vessels, causing hardening and weakening of the vessel walls, leading to a range of vascular diseases. Furthermore, because it is administered so rapidly, the body absorbs too much medication at once, which inevitably increases visceral burden and significantly amplifies adverse drug reactions.

[0003] In order to solve the above problems, this application is proposed. Summary of the Invention

[0004] The purpose of the present invention is to address the above-mentioned problems existing in the prior art and provide a breathing bag. The breathing bag can adopt a non-intravenous injection treatment method when the patient's condition is serious, improve the treatment safety, reduce the burden on the human viscera, and reduce adverse reactions, thereby solving the problems of poor treatment safety and high burden on the human viscera of the existing intravenous injection treatment of asthma.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A breathing bag, comprising a balloon, a mounting tube, a safety valve, a duckbill valve, an exhalation valve and a ventilator, wherein one end of the mounting tube is connected to one end of the balloon, the safety valve, the duckbill valve and the exhalation valve are connected to the mounting tube, the exhalation valve has an air passage 1 therein, and is characterized in that it also comprises a treatment piece 1, the treatment piece 1 comprises a shell, the shell has an air passage 2 therein, one end of the air passage 2 is an inlet, and the other end is an outlet, the inlet of the air passage 2 is communicated with the air passage 1, the outlet of the air passage 2 is communicated with the ventilator, the shell also has therapeutic drugs, and when the duckbill valve is opened, the therapeutic drugs can be discharged from the outlet along the air flow into the ventilator.

[0007] The breathing bag is a commonly used tool in the medical respiratory field. Generally speaking, its purpose is to provide artificial ventilation and oxygen supply to patients who have no artificial airway, no spontaneous breathing, or weak and irregular breathing, and severe ventilation problems. The traditional structure generally consists of a mask, a duckbill valve, a balloon, an oxygen storage valve, an oxygen storage bag and an oxygen catheter. The mask is connected to the exhalation valve, the oxygen storage bag is connected to the balloon, and the oxygen catheter is connected to the balloon and the oxygen source. Before operation, the breathing bag components must be inspected. The airway must be opened and foreign objects in the mouth removed. The mask is then placed over the patient's mouth and nose. The middle, ring, and pinky fingers of one hand are placed on the patient's lower jaw to hold the patient's mouth open. The index finger and thumb are placed on the mask (in a CE position), pressing tightly to prevent air leaks. The right hand squeezes the bag. After the bag is squeezed, oxygen enters the duckbill valve through the mounting tube. The one-way valve flap of the duckbill valve expands, allowing oxygen to continue into the exhalation valve's air passage 1, then into the mask, and finally into the patient's body to achieve oxygen supply. The exhalation valve has a deflation flap, which abuts against the exhalation valve with a gap between them. When the patient's mouth closes or air passage 1 becomes blocked, oxygen can directly reverse direction to open the deflation flap, achieving rapid deflation. The mounting tube is used to install various valves. The above is the basic operating procedure for the breathing bag, and the details are not detailed here. The installation methods and detailed structures of components such as the duckbill valve, exhalation valve, and safety valve are also not described here, as they are all prior art.

[0008] In this solution, a treatment component 1 is added to the breathing bag. After pressing the bag, oxygen passes through the air passage 1 and the air passage 2. Under the action of oxygen, the therapeutic drug in the shell follows the air flow into the ventilation component, thereby acting on the respiratory tract and quickly relieving asthma symptoms. Here, the ventilation component plays the role of ventilation conduction. This solution uses extrusion power to deliver therapeutic drugs into the patient's respiratory tract, and simulates the patient's inhalation operation through reverse injection, realizing a non-intravenous treatment method, greatly improving the safety of treatment, reducing the burden on the human body's internal organs, and reducing adverse reactions. At the same time, this external force injection method has sufficient oxygen power and rapid drug movement. Compared with active inhalation, it can make the drug quickly reach the respiratory tract and take effect quickly. In addition, it also makes full use of the basic function of the breathing bag to supply oxygen to the patient and help him quickly resume normal breathing. The concept is novel and ingenious.

[0009] In the above-mentioned breathing bag, the ventilation piece is a mask.

[0010] When the ventilator is a mask, the mask and housing are plugged or tightly fitted and can be removed at any time. In this solution, the respiratory bag serves both oxygen supply and therapeutic purposes. The oxygen supply function is not discussed in detail, as it is a basic function. During treatment, the patient's mouth is opened, the mask is placed over the patient's face until it is airtight, and the balloon is squeezed. The therapeutic drug, driven by oxygen, is transported through the mask to the patient's mouth and ultimately to the respiratory area, completing the treatment. This solution allows for rapid treatment, eliminating the need for additional procedures.

[0011] In the above-mentioned breathing bag, the ventilation piece is a tracheal tube, the inner end of the tracheal tube extends into the patient's respiratory tract, and the outer end of the tracheal tube is connected to the second outlet of the air passage.

[0012] In this scheme, the endotracheal tube is directly inserted into the patient's respiratory tract. During treatment, the outer end of the endotracheal tube is connected to the second outlet of the airway (usually a tight fit), and then the balloon is pressed. The therapeutic drug can directly enter the respiratory tract through the endotracheal tube, which can prevent the therapeutic drug from acting on irrelevant parts such as the mouth, so that the therapeutic drug can fully exert its effect and reduce the loss of therapeutic drugs. It has strong targeting, and since other parts do not come into contact with the therapeutic drug, there are no side effects and strong safety performance.

[0013] In the above-mentioned breathing bag, from the inside to the outside in the mounting tube are the duckbill valve, the exhalation valve and the treatment piece 1.

[0014] Oxygen opens the duckbill valve, passes through gas passage 1 in the exhalation valve, and then through gas passage 2 in treatment element 1. With this arrangement, if the patient's mouth is closed or the passage is blocked, the therapeutic drug is far from the deflation flap, so oxygen is discharged directly through the deflation flap of the exhalation valve, without passing through the therapeutic drug and being carried out through the deflation flap. Conversely, if treatment element 1 is placed between the duckbill valve and the exhalation valve, if the patient's mouth is closed or the passage is blocked, oxygen may pass through the therapeutic drug and be carried out through the deflation flap, posing a risk of drug waste and leakage.

[0015] In the above-mentioned breathing bag, the shell includes a left shell and a right shell, both of which are semi-cylindrical and can be interlocked. The left shell is provided with a first branch channel, and the right shell is provided with a second branch channel. The first branch channel and the second branch channel constitute the second air passage.

[0016] The split structure of the shell facilitates the replacement of therapeutic drugs.

[0017] In the above-mentioned breathing bag, one end of the left shell and the right shell has an external thread, and the air passage one has an internal thread.

[0018] After the shell is assembled, one end of the shell is screwed into the expiration channel 2 to achieve the connection between the exhalation valve and the shell, thereby achieving unobstructed flow between the exhalation channel 1 and the exhalation channel 2.

[0019] In the above-mentioned breathing bag, the inner wall of the left shell has a plurality of buckling parts, and the inner wall of the right shell has a plurality of corresponding buckling grooves.

[0020] The detachable connection between the left shell and the right shell is achieved by providing the fastening portion and the fastening groove. In practice, there are many other alternatives.

[0021] In the above-mentioned breathing bag, the snap-fitting part includes a cylindrical connecting column and a spherical snap-fitting ball, the snap-fitting groove is spherical, one end of the connecting column is connected to the left shell body, and the other end of the connecting column is connected to the snap-fitting ball, the diameter of the snap-fitting groove is smaller than that of the snap-fitting ball, and the snap-fitting ball can enter the snap-fitting groove.

[0022] The structure is to realize that the snap ball enters the snap groove by extrusion deformation, and after being squeezed in, the snap ball resets to realize the connection between the left shell and the right shell. When separating the left shell and the right shell, the two are pried apart to deform the snap ball and disengage it from the snap groove.

[0023] In the above-mentioned breathing bag, the therapeutic drug is stored in a capsule, and the capsule is fixed in the second air passage. There is a flow gap between the capsule and the second air passage, and the therapeutic drug can flow out after the capsule is punctured.

[0024] When the medication in the capsule is depleted, the shell can be opened and replaced. Puncturing the capsule creates a leak, allowing air to flow through the hole and carry away the medication. This built-in capsule design allows for immediate use, offering a clever and convenient design.

[0025] In the above-mentioned breathing bag, the therapeutic drug is in the form of powder.

[0026] Powders do not flow freely like liquids. Powders are light in weight and can flow quickly into the respiratory tract with the airflow, making the effect quick and effective.

[0027] In the above-mentioned breathing bag, the treatment part also includes a fixing structure, which includes a T-shaped connecting frame, the bottom end of the connecting frame is fixedly connected to the inner wall of the shell, and there is an O-ring on both ends of the connecting frame. The two ends of the capsule are respectively extended into the two O-rings to achieve axial fixation.

[0028] The inner diameter of the O-ring is smaller than the maximum outer diameter of the capsule. Therefore, when the two ends of the capsule are inserted into the two O-rings, the two ends of the capsule can be restricted, thereby preventing the capsule from axial movement and preventing it from being affected by puncture operations and airflow movement. The fixing structure has a stable fixing effect on the capsule.

[0029] In the above-mentioned breathing bag, the treatment component 1 further includes a puncture structure, which includes a through hole opened on the shell, the through hole penetrates to the capsule, and the outer end of the through hole is blocked by a stud.

[0030] In this solution, puncture is required by an external tool, which is to unscrew the screw and use a sharp object to puncture the capsule, and then reset the screw. This solution reduces the complexity of the treatment part and simplifies the structure.

[0031] In the above-mentioned breathing bag, the treatment part 1 also includes a puncture structure, which includes a through-mounting hole opened on the shell, the through-mounting hole passes through the capsule, and a needle is connected to the through-mounting hole. The inner end of the needle is a sharp end, and the outer end of the needle is a pressing end. The puncture structure also includes a spring sleeved outside the needle.

[0032] In this solution, the treatment piece has a puncture structure. You only need to operate the pressing end to make the sharp end puncture the capsule. After releasing your hand, it will automatically reset through the spring. The puncture structure of this solution makes the capsule puncture operation convenient and has strong operational stability. It can avoid the occurrence of slippage and puncture. At the same time, it can puncture both sides of the capsule more smoothly and fully, so that the therapeutic drug can flow out fully.

[0033] In the above-mentioned breathing bag, the inner wall of the through-mounting hole has a blocking edge, one end of the spring is fixedly connected to the blocking edge, and the other end of the spring is fixedly connected to the pressing end.

[0034] The needle is connected to the through-mounting hole through a spring. One end of the spring is fixed to the retaining edge, and the other end of the spring is fixed to the pressing end. This can be achieved by spot welding, tight fit, etc.

[0035] A breathing bag comprises a balloon, a mounting tube, a safety valve, a duckbill valve, an exhalation valve and a ventilator, wherein one end of the mounting tube is connected to one end of the balloon, the safety valve, the duckbill valve and the exhalation valve are connected to the mounting tube, the exhalation valve has an air passage 1 therein, and is characterized in that it also comprises a treatment component 2, wherein the treatment component 2 has therapeutic drugs therein, and when the one-way valve flap of the duckbill valve is opened, the treatment component 2 breaks open and the therapeutic drugs leak out of the treatment component 2 into the air passage 1, and the air passage 1 is communicated with the ventilator.

[0036] In this solution, treatment component 2 replaces treatment component 1. When the balloon is squeezed, oxygen acts on the duckbill valve to open the one-way valve flap. The one-way valve flap opens by moving outward, touching treatment component 2 during the process. Under the action of the impact, treatment component 2 breaks open, forming a leakage channel. The therapeutic drug leaks out of the leakage channel into the air channel 1, then into the ventilation component, and finally into the human respiratory tract to take effect. This solution uses the impact of the one-way valve flap opening to squeeze treatment component 2, allowing the drug inside the treatment component to flow out. It fully utilizes the existing structure, has a clever structural design, and a simple structure. The ventilation component can be a mask or an endotracheal tube, etc., both of which are directly connected to the breathing valve. The details are not described in detail, as it is existing technology.

[0037] In the above-mentioned breathing bag, the second treatment element includes a circular ring-shaped bag body with a hollow interior, the bag body has a convex body protruding outward and with a hollow interior, the convex body is separated from the bag body by a diaphragm, and a flow hole is opened on the convex body.

[0038] The therapeutic drug is filled in the capsule. The therapeutic drug is preferably in powder form and the internal cavity of the capsule is not filled with the therapeutic drug. A small amount of space is left to facilitate the impact of the impact. When the one-way valve disc squeezes the capsule, the squeezing force breaks the diaphragm, and the therapeutic drug enters the convex body and finally flows out from the flow hole. The convex body is generally set downward to facilitate the smooth flow of the therapeutic drug. The setting of the convex body plays a transitional role, which can prevent the therapeutic drug from leaking directly from the rupture of the diaphragm, which will result in a fast flow rate, drug waste, and the risk of overdose. When the diaphragm is broken, the drug enters the convex body and flows out through the flow hole with a smaller aperture, limiting the flow rate and reducing drug waste. The structural design is ingenious.

[0039] In the above-mentioned breathing bag, the wall thickness of the diaphragm is smaller than the wall thickness of the bag body.

[0040] This size design enables the one-way valve disc to successfully break through the diaphragm when squeezing the sac.

[0041] In the above-mentioned breathing bag, the second treatment member is made of nylon, and the thickness of the diaphragm does not exceed 0.5 mm.

[0042] This size design enables the impact force of the one-way valve disc to smoothly break open the diaphragm.

[0043] In the above-mentioned breathing bag, a circular embedded groove is provided on the inner wall of the inner end of the exhalation valve, and a part of the bag body is embedded in the embedded groove.

[0044] The second treatment component is disposable and can be installed by simply snapping the capsule into the embedded groove.

[0045] Compared with the existing technology, this breathing bag has the following advantages:

[0046] 1. This breathing bag uses extrusion power to deliver therapeutic drugs into the patient's respiratory tract, and simulates the patient's oral inhalation operation through reverse injection, realizing non-intravenous treatment, greatly improving treatment safety, reducing the burden on the human body's internal organs, and reducing adverse reactions.

[0047] 2. This breathing bag has sufficient oxygen power through external force injection, and the drug moves quickly. Compared with active inhalation, it can make the drug reach the respiratory tract quickly and take effect quickly.

[0048] 3. This breathing bag makes full use of the basic functions of ordinary breathing bags to supply oxygen to patients and help them quickly restore normal breathing. The design is novel and ingenious.

[0049] 4. This breathing bag features a built-in capsule design. When the medication is depleted, the shell can be opened to replace the capsule. Puncturing the capsule creates a leak, allowing air to flow through the hole and carry away the medication. This ingenious and convenient design allows for immediate use.

[0050] 5. The therapeutic drug in this breathing bag is powder. Powder does not flow freely like liquid. Powder is light in weight and can flow quickly into the respiratory tract with the air flow, making the effect quick and effective.

[0051] 6. The breathing bag squeezes the treatment piece 2 with the help of the impact when the one-way valve flap opens, so that the medicine inside the treatment piece can flow out, making full use of the existing structure, with ingenious structural design and simple structure.

[0104] Example 1

[0105] like Figures 1 to 8 As shown, the breathing bag includes a balloon 1, a mounting tube 2, a safety valve 3, a duckbill valve 4, an exhalation valve 5 and a ventilator. One end of the mounting tube 2 is connected to one end of the balloon 1, and the safety valve 3, the duckbill valve 4 and the exhalation valve 5 are connected to the mounting tube 2. The exhalation valve 5 has an air passage 5a therein, and also includes a treatment piece 6. The treatment piece 6 includes a shell 6a, and the shell 6a has an air passage 6b therein. One end of the air passage 6b is an inlet 6b1, and the other end is an outlet 6b2. The inlet 6b1 of the air passage 6b is connected to the air passage 5a, and the outlet 6b2 of the air passage 6b is connected to the ventilator. The shell 6a also contains therapeutic drugs. When the duckbill valve 4 is opened, the therapeutic drugs can be discharged from the outlet 6b2 along the air flow into the ventilator.

[0106] The breathing bag is a commonly used tool in the field of medical respiration. Generally, its purpose is to provide artificial ventilation and oxygen supply to patients who have no artificial airway, no spontaneous breathing, or weak and irregular breathing, and severe ventilation problems. The traditional structure generally consists of a mask, a duckbill valve 4, a balloon 1, an oxygen storage valve, an oxygen storage bag and an oxygen catheter. There is a socket on the mask, through which the mask is connected to the exhalation valve 5 and connected. The oxygen storage bag is connected to the balloon 1, and the oxygen catheter is connected to the balloon 1 and the oxygen source. Before operation, it is necessary to first inspect all components of the breathing bag, then open the airway and remove foreign objects from the mouth. Then, cover the patient's mouth and nose with the mask. Use the middle finger, ring finger, and little finger of one hand to place the patient's lower jaw to keep the patient's mouth open. Place the index finger and thumb on the mask (in CE technique), press tightly to prevent air leakage, and squeeze the balloon 1 with the right hand. After the balloon 1 is squeezed, oxygen enters the duckbill valve 4 through the installation tube 2. The one-way valve flap 4a of the duckbill valve 4 expands, and the oxygen continues to enter the air passage 5a of the exhalation valve 5, then enters the mask, and finally enters the patient's body to achieve oxygen supply. The exhalation valve 5 has a deflation flap 5b. The duckbill valve 4 and the exhalation valve 5 are close to each other with a gap between them. When the patient's mouth is closed or the air passage 5a is blocked, the oxygen can directly move in the opposite direction to open the deflation flap 5b, achieving rapid deflation. The installation tube 2 is used to install various valves. The above is the basic operation process of the breathing bag, which will not be described in detail. The installation method and detailed structure of components such as the duckbill valve 4, the exhalation valve 5, and the safety valve 3 will not be described in detail either, as they are all existing technologies.

[0107] In this solution, a therapeutic component 6 is added to the breathing bag. After pressing the balloon 1, oxygen passes through the air passage 1 5a and the air passage 2 6b. Under the action of oxygen, the therapeutic drug in the shell 6a enters the ventilator along the airflow, thereby acting on the respiratory tract and quickly relieving asthma symptoms. Here, the ventilator plays the role of ventilation conduction. This solution uses extrusion power to deliver therapeutic drugs into the patient's respiratory tract, and simulates the patient's oral inhalation operation through reverse injection, realizing a non-intravenous treatment method, greatly improving the safety of treatment, reducing the burden on the human body's internal organs, and reducing adverse reactions. At the same time, this external force injection method has sufficient oxygen power and rapid drug movement. Compared with active inhalation, it can make the drug quickly reach the respiratory tract and take effect quickly. In addition, it also makes full use of the basic function of the breathing bag to supply oxygen to the patient and help him quickly resume normal breathing. The concept is novel and ingenious.

[0108] Specifically, the ventilator is a mask. When the ventilator is a mask, the mask and the housing 6a are plugged or tightly fitted and can be removed at any time. In this solution, the respiratory bag serves both oxygen supply and treatment functions. The oxygen supply function is not described in detail, as it is a basic function. During treatment, the patient's mouth is opened, and the mask is placed on the patient's face until it is airtight. Then, the balloon 1 is squeezed. The therapeutic drug, driven by oxygen, is transmitted through the mask to the patient's mouth and finally reaches the respiratory area, achieving the treatment function. This solution allows for rapid treatment and eliminates the need for other operations. In another alternative solution, the ventilator is a tracheal tube, the inner end of which extends into the patient's respiratory tract, and the outer end of which is connected to the outlet 6b2 of the second air passage 6b. In this solution, the breathing bag can also play the dual roles of oxygen supply and treatment. The endotracheal tube is directly inserted into the patient's respiratory tract. During treatment, the outer end of the endotracheal tube is connected to the outlet 6b2 of the second air passage 6b (generally a tight fit), and then the balloon 1 is pressed. The therapeutic drug can directly enter the respiratory tract through the endotracheal tube, which can prevent the therapeutic drug from acting on irrelevant parts such as the mouth, so that the therapeutic drug can fully and quickly take effect, reducing the loss of the therapeutic drug. It has strong targeting, and since other parts do not come into contact with the therapeutic drug, there are no side effects and strong safety performance.

[0109] Specifically, from inside to outside, within the mounting tube 2, there are the duckbill valve 4, the exhalation valve 5, and the treatment element 1 6. Oxygen opens the duckbill valve 4, passes through the air passage 1 5a in the exhalation valve 5, and then through the air passage 2 6b in the treatment element 1 6. With this arrangement, if the patient's mouth is closed or the passage is blocked, the therapeutic drug is far from the deflation flap 5b, so oxygen is discharged directly through the deflation flap 5b of the exhalation valve 5, without passing through the therapeutic drug and being carried away from the deflation flap 5b. Conversely, if the treatment element 1 6 is positioned between the duckbill valve 4 and the exhalation valve 5, if the patient's mouth is closed or the passage is blocked, oxygen may pass through the therapeutic drug and be carried away from the deflation flap, posing a risk of drug waste and leakage. The housing 6a comprises a left housing 6a1 and a right housing 6a2, both semi-cylindrical and interlocking. A first branch 6a1a is defined within the left housing 6a1, while a second branch 6a2a is defined within the right housing 6a2. These two branches 6a1a and 6a2a form a second air passage 6b. The split structure of the housing 6a facilitates the replacement of therapeutic medications. One end of the left housing 6a1 and the right housing 6a2 has external threads, while the first air passage 5a has internal threads. After assembly of the housing 6a, one end of the housing 6a is threaded into the second air passage, connecting the exhalation valve 5 to the housing 6a, thereby ensuring unimpeded passage between the first air passage 5a and the second air passage 6b. The inner wall of the left housing 6a1 has several snap-fitting portions 6a1b, while the inner wall of the right housing 6a2 has several corresponding snap-fitting grooves 6a2b. The arrangement of the snap-fit ​​portion 6a1b and the snap-fit ​​groove 6a2b enables a detachable connection between the left housing 6a1 and the right housing 6a2. In practice, there are many other alternatives. The snap-fit ​​portion 6a1b includes a cylindrical connecting post 6a1b1 and a spherical snap-fit ​​ball 6a1b2. The snap-fit ​​groove 6a2b is spherical. One end of the connecting post 6a1b1 is connected to the left housing 6a1, and the other end of the connecting post 6a1b1 is connected to the snap-fit ​​ball 6a1b2. The snap-fit ​​groove 6a2b has a smaller diameter than the snap-fit ​​ball 6a1b2, allowing the snap-fit ​​ball 6a1b2 to enter the snap-fit ​​groove 6a2b. The above structure enables the snap-fit ​​ball 6a1b2 to enter the snap-fit ​​groove 6a2b through extrusion deformation. After being squeezed in, the snap-fit ​​ball 6a1b2 resets to achieve the connection between the left housing 6a1 and the right housing 6a2. When separating the left shell 6a1 and the right shell 6a2, the two are simply pried apart to deform the snap-fit ​​ball 6a1b2 and disengage it from the snap-fit ​​groove 6a2b.

[0110] Specifically, the therapeutic drug is stored in capsule 7, which is fixed in air passage 2 6b. A flow gap 76b is provided between capsule 7 and air passage 2 6b, allowing the therapeutic drug to flow out after puncturing capsule 7. When the therapeutic drug in capsule 7 is used up, the shell 6a can be opened to replace capsule 7. Puncturing capsule 7 forms a leak hole, through which airflow carries away the therapeutic drug. This built-in capsule 7 allows for immediate use, with an ingenious and convenient design. The therapeutic drug is a powder. Unlike liquids, powders are lightweight and can flow rapidly into the respiratory tract with the airflow, allowing them to act quickly and effectively. Treatment element 1 6 also includes a fixing structure, which includes a T-shaped connecting frame 8. The bottom end of connecting frame 8 is fixedly connected to the inner wall of shell 6a. Each end of connecting frame 8 has an O-ring 8a. The two ends of capsule 7 extend into the two O-rings 8a for axial fixation. The inner diameter of the O-ring 8a is smaller than the maximum outer diameter of the capsule 7. Therefore, when the two ends of the capsule 7 are inserted into the two O-rings 8a, the two ends of the capsule 7 can be restricted, thereby preventing the capsule 7 from axial movement and being affected by the puncture operation and airflow movement. The fixing structure has a stable fixing effect on the capsule 7.

[0111] Treatment element 1 (6) also includes a puncturing structure, comprising a through-hole (6d) defined in housing (6a). Through-hole (6d) extends through capsule (7). A puncture needle (10) is connected within through-hole (6d). Needle (10) has a sharp tip (10a) at its inner end and a pressing tip (10b) at its outer end. The puncturing structure also includes a spring (11) positioned over needle (10). In this embodiment, treatment element 1 (6) incorporates a built-in puncturing structure. Simply pressing tip (10b) causes sharp tip (10a) to puncture capsule (7). Release of the pressure triggers automatic reset by spring (11). This puncturing structure facilitates capsule (7) puncture and enhances operational stability, preventing slippage. It also facilitates smoother puncture of both sides of capsule (7), ensuring adequate puncture and release of the therapeutic drug. A retaining edge (6d1) is located within the through-hole (6d). One end of spring (11) is fixedly attached to retaining edge (6d1), while the other end of spring (11) is fixedly attached to pressing tip (10b). The puncture needle 10 is connected to the through-mounting hole 6d via a spring 11. One end of the spring 11 is fixed to the retaining edge 6d1, and the other end is fixed to the pressing end 10b. This can be achieved by spot welding, tight fitting, or other methods. Regarding the puncture structure, the normal oxygen supply function of the breathing bag can be directly used without puncturing the capsule 7. Of course, if a higher air flow rate is desired, the treatment element 16 can be completely disassembled and the ventilation element can be connected to the exhalation valve 5. This perfectly achieves functional switching, with an ingenious structural design and convenient and fast operation.

[0112] Example 2

[0113] like Figure 9As shown, this embodiment differs from the first embodiment in its puncture structure. Specifically, the puncture structure includes a through hole 6c formed in the housing 6a, which extends to the capsule 7. The outer end of the through hole 6c is blocked by a stud 9. In this solution, puncture is performed using an external tool. The method is to unscrew stud 9, puncture the capsule 7 with a sharp object, and then reposition stud 9. This solution reduces the complexity of the treatment element 6 and simplifies the structure.

[0114] Example 3

[0115] like Figures 10 to 12 As shown, this breathing bag includes a balloon 1, a mounting tube 2, a safety valve 3, a duckbill valve 4, an exhalation valve 5, and a ventilator. One end of the mounting tube 2 is connected to one end of the balloon 1. The safety valve 3, duckbill valve 4, and exhalation valve 5 are connected to the mounting tube 2. The exhalation valve 5 has an air passage 1 (5a) therein. The exhalation valve 5 also includes a second treatment element 12, which contains therapeutic drugs. When the one-way valve flap 4a of the duckbill valve 4 opens, the second treatment element 12 ruptures and the therapeutic drugs leak out of the treatment element 12 into the air passage 1 (5a), which communicates with the ventilator. In this embodiment, the second treatment element 12 replaces the first treatment element. When the balloon 1 is squeezed, oxygen acts on the duckbill valve 4, causing the one-way valve flap 4a to open. The one-way valve flap 4a opens, moving outward, contacting the treatment element 2 12. The impact of this force causes the treatment element 2 12 to break open, forming a leakage channel. The therapeutic drug leaks through the leakage channel into the air passage 1 5a, then into the ventilator, and finally into the human respiratory tract to take effect. This solution utilizes the impact of the one-way valve flap 4a opening to squeeze the treatment element 2 12, allowing the drug inside the treatment element to flow out. This solution fully utilizes existing structures and has an ingenious and simple structural design. The ventilator can be a mask or an endotracheal tube, both of which are directly connected to the breathing valve. The details are not detailed here, as this is prior art.

[0116] Specifically, therapeutic element 2 12 includes a circular, hollow capsule 12a. Capsule 12a has a protrusion 12b protruding outward from the capsule 12a, which is separated from the capsule 12a by a diaphragm 12c. Protrusion 12b is provided with a flow hole 12b1. The therapeutic drug is filled in capsule 12a, preferably in the form of a powder. The drug does not completely fill the interior of capsule 12a, leaving a small gap to facilitate the impact of the force. When the one-way valve 4a squeezes capsule 12a, the squeezing force breaks through diaphragm 12c, allowing the drug to enter protrusion 12b and ultimately flow out of flow hole 12b1. Protrusion 12b is generally positioned downward to facilitate smooth flow of the drug. The provision of protrusion 12b serves as a transitional mechanism, preventing the drug from directly leaking out of the ruptured diaphragm 12c. This would result in a rapid flow rate, drug waste, and the risk of overdose. When the diaphragm 12c is broken, the drug enters the convex body 12b and flows out through the flow hole 12b1 with a smaller aperture, limiting the flow rate and reducing drug waste. The structural design is ingenious. The wall thickness of the diaphragm 12c is less than the wall thickness of the capsule 12a. This size design enables the one-way valve flap 4a to smoothly break through the diaphragm 12c when squeezing the capsule 12a. The treatment piece 12 is made of nylon, and the thickness of the diaphragm 12c does not exceed 0.5mm. This size design enables the impact force of the one-way valve flap 4a to smoothly break through the diaphragm 12c. A circular embedded groove 5c is provided on the inner wall of the inner end of the exhalation valve 5, and a portion of the capsule 12a is embedded in the embedded groove 5c. The treatment piece 12 is disposable, and the capsule 12a can be snapped into the embedded groove 5c during installation.
