Respiratory bag for correcting over ventilation

Technical Field

The utility model relates to a medical supplies, concretely relates to correct hyperventilation respiratory capsule.

Background

The hyperventilation is a symptom caused by over-ventilation beyond the physiological metabolic needs, is usually seen in women with the manifestation of neurosis or factors inducing mental stress, is free from any cause of organic lesions, and has the symptoms of accelerated respiratory movement, reduced arterial blood carbon dioxide partial pressure (lower than 5kPa), respiratory alkalosis and sympathetic nervous system excitation, thus clinically showing various symptoms.

A clinically common mode of treating hyperventilation is to inhale a proper amount of carbon dioxide to relieve arterial blood carbon dioxide partial pressure drop. The common mode is that a patient wears a mask or a headgear plastic bag, so that the patient inhales the exhaled air, and the exhaled air is inhaled back into the body due to the fact that the exhaled air contains more carbon dioxide, so that the symptom of over ventilation can be effectively relieved. However, in clinical practice, it has been found that the exhaled air collected by wearing the mask is limited and the therapeutic effect is not good. Although the mode of the headgear plastic bag has a certain treatment effect, the operation and the fixation are inconvenient, and the appearance is also not beautiful. In addition, if the patient suffering from hyperventilation is a tracheotomy patient, the patient is clinically corrected by using a respirator matched with a sedative drug, and the treatment mode has the problems of doing a little bit more for the patient capable of breathing autonomously, wasting medical resources and increasing the economic burden of the patient.

In summary, the prior art has no special articles for treating over-ventilation, and it is difficult to treat over-ventilation symptoms conveniently and effectively.

Detailed Description

As shown in fig. 1 and fig. 2, the breath bag for correcting over ventilation of the present invention comprises a trachea 1, a gas storage bag 2 and a connector 3. The air pipe 1 is a straight hard plastic pipe, and a plurality of vent holes 11 are formed in the side face of the air pipe 1. The gas storage bag 2 is approximately spherical in an expansion state, and a cavity for filling gas is formed inside the gas storage bag. Two ends of the air storage bag 2 are provided with through holes matched with the air pipe 1. The trachea 1 passes through the cross-under hole at the two ends of the gas storage bag 2, so that the trachea 1 passes through the inside of the gas storage bag 2, and the two ends of the trachea 1 are exposed out of the gas storage bag 2. The connecting position of the air pipe 1 and the air storage bag 2 is sealed through sealant so as to ensure the air tightness of the connecting position. The air storage bag 2 is wrapped outside the side surface of the air pipe 1, and the air pipe 1 is communicated with the inside of the air storage bag 2 through a vent hole 11 on the side surface. One end of the air pipe 1 is communicated with the connector 3, and the other end is provided with a ventilation hole cover 4. The connector 3 is a special connector and is used for being connected with a tracheotomy sleeve, a tracheal intubation sleeve or a breathing mask. The vent hole cover 4 is used for balancing the internal and external air pressure of the air storage bag 2.

The utility model discloses a use specifically as follows to the trachea opens patient's overventilation treatment process for the example, opens the bushing with connector 3 and trachea. At the moment, the gas exhaled by the patient flows into the trachea 1 from the connector 3, and flows into the gas storage bag 2 through the vent hole 11 on the side surface of the trachea 1 for storage. When the patient inhales, the expired air in the air storage bag 2 is sucked back into the patient along the air pipe 1, so as to treat the patient with over-ventilation.

The utility model discloses can effectively collect the gas of patient's exhalation, make the carbon dioxide concentration in the patient inspired gas high, can effectively alleviate the symptom of excessively ventilating, have good correction treatment. When in use, the connector 3 is connected with a tracheotomy sleeve, a trachea cannula sleeve or a breathing mask, and the operation is convenient and the efficiency is high. The air storage bag 2 is convenient to fix and safe and attractive in use process. Can be applicable to trachea incision patient's correction treatment process, need not to adopt the breathing machine to correct the treatment, can reduce patient's treatment expense by a wide margin, reduce patient's economic burden, more economical and practical. The ventilation hole cover 4 can balance the internal and external air pressure of the air storage bag 2, so that the internal air pressure of the air storage bag 2 is close to the atmospheric pressure, the lung of a patient is prevented from doing more breathing work, and the patient can breathe smoothly and easily in the treatment process.

As shown in fig. 2, a circular through hole 41 is formed in the middle of the vent cover 4, and a plurality of soft membranes 42 distributed in a petal shape are disposed in the through hole 41. The soft film 42 is made of soft rubber, and is soft and deformable. In this embodiment, the number of the soft films 42 is four, each soft film is in a sector shape, the radian of each soft film is 90 °, the sum of the areas of the four soft films 42 is approximately equal to the cross-sectional area of the through hole 41, and the through holes 41 can be closed together after the four soft films 42 are close to each other. One end of the soft film 42 is connected to the edge of the through hole 41, and the other end is a free end, in this embodiment, the arc edge of the soft film 42 is connected to the edge of the through hole 41 by gluing, and the vertex angle thereof is located at a position close to the center point of the through hole 41 and is a free end. The soft film 42 is used for balancing the internal and external air pressures of the air reservoir 2. The specific principle is that the soft film 42 is soft and one end of the apex angle is a free end, so that the soft film can swing along with the pressure difference between the inside and the outside of the air storage bag 2, and the through hole 41 is in a closed or open state. The specific process is that when the air pressure in the air storage bag 2 is larger than the atmospheric pressure, the soft film 42 is opened outwards, and part of the air in the air storage bag 2 is exhausted out of the air storage bag 2, so that the air pressure in the air storage bag 2 tends to be balanced. When the internal air pressure of the air storage bag 2 is lower than the atmospheric pressure, the soft film 42 is opened inwards, and the external air enters the air storage bag 2, so that the internal air pressure and the external air pressure of the air storage bag 2 tend to be balanced. When the air pressure in the air storage bag 2 is equal to the atmospheric pressure, the soft film 42 and the through hole 41 are located on the same plane, and the through hole 41 is sealed by a plurality of soft films 42 together, so that the air storage bag 2 is in a relatively isolated state. The structure of the soft film 42 in the middle of the ventilation hole cover 4 can make the air pressure inside the air storage bag 2 close to the atmospheric pressure, avoid the lung of the patient to do more breathing work, and make the patient breathe smoothly and easily in the treatment process.

An oxygen tube 5 is further arranged in the embodiment, and the oxygen tube 5 can be a common medical oxygen therapy tube. One end of the oxygen tube 5 is communicated with the inside of the gas storage bag 2, and the other end is communicated with an oxygen source. The oxygen tube 5 is used for supplementing oxygen into the gas storage bag 2, so that the oxygen concentration of the gas in the gas storage bag 2 can be increased, and the sufficient oxygen content in the gas inhaled by the patient is ensured.

The gas storage bag 2 is made of polyethylene material, the polyethylene material has no elasticity, so that the lung of a patient can be prevented from doing more breathing work, and the patient can breathe smoothly in the treatment process.

The capacity of the air storage bag 2 is 600-650ml, the capacity is moderate, the air storage bag can be suitable for most over-ventilation treatment processes, and the treatment processes can be conveniently fixed.

The vent holes 11 are circular holes, and the number of the vent holes is ten. The shape and number of the vent holes 11 can make the gas exchange between the gas pipe 1 and the gas storage bag 2 smooth.
