Description

Oxygen supply apparatus

The present invention relates to an oxygen supply device including a cover for preventing oxygen leakage from a Bag Valve Mask (BVM) when oxygen is provided to a patient.

Bag Valve Mask (hereinafter, BVM) is one of the useful equipment for artificial ventilation provided to patients with cardiac arrest and respiratory arrest.

In general, BVM is used to administer high-concentration oxygen to help maintain stable ventilation (breathing) in emergency patients or critically ill patients. It is a tool for effect.

BVM is generally divided into three sizes according to the age group of a person, and the size of the bag and the shape and size of the mask may be different for each. Ventilation properly performed using BVM at the stage before arriving at the hospital during transport of emergency patients can be expected to be as effective as providing ventilation using an airway maintainer such as endotracheal intubation.

In general, when performing ventilation with the BVM, hold the bag with one hand and hold the chin with the other hand and use a technique called 'EC clamp technique' to adhere the mask part of the BVM. The third, fourth, and fifth fingers of one hand make the shape of the alphabet 'E' to raise the patient's chin, and the remaining first and second fingers make the shape of the alphabet 'C' and use it to attach the mask to the patient's face.

The above technique is dependent on the skill level of the user, and if an action is taken on a patient with an incorrect posture, an appropriate response may not be made.

For example, the 3rd, 4th, and 5th fingers make the shape of the alphabet 'E' and lift the patient's chin to open the patient's airway smoothly. can In this case, the problem of oxygen leaking between the mask and the patient's face frequently occurs because sufficient force is not applied to the remaining fingers that have made the relatively letter 'C' shape.

The ventilation unit 3 may be provided for administering a high concentration of oxygen while maintaining ventilation of the patient. When the patient's respiratory rate decreases or it is difficult for the patient to breathe on his/her own, it is a composition that breathes directly into the patient, so the same effect as CPR can be expected.

The ventilation unit 3 may be provided with a material that can be contracted and expanded. The ventilation unit 3 has one end connected to the first valve 4 and oxygen is supplied through the oxygen storage unit 5, and then the ventilator 3 applies pressure to the ventilation unit 3 to activate the ventilation unit 3 Upon contraction, the first valve 4 is closed and oxygen can be supplied to the patient.

Of course, the ventilation unit 3 may have a different capacity to hold oxygen depending on the size. And when the operator contracts the ventilation unit 3, the amount of oxygen supplied to the patient is preferably at least 0.5L or more.

That is, the amount of oxygen moving toward the second valve 2 through the contraction of the ventilation unit 3 is preferably at least 0.5L or more.

The second valve 2 is connected to the other end of the ventilator 3 so that oxygen stored in the ventilator 3 flows only in a direction from the ventilator 3 toward the mask 120 . can do.

The mask 120 may be in close contact with the patient's face to deliver oxygen supplied from the ventilation unit 3 through the second valve 2 to the patient.

The mask 120 may include an inlet 121 , a body 123 , and a first contact 125 . The inlet 121 may be connected to the second valve 2 to form a flow path through which oxygen supplied from the ventilator 3 flows into the mask 120 .

The body 123 may extend from the inlet 121 in a direction in which a cross-sectional area is widened. More specifically, the body 123 may be provided in a shape in which the cross-sectional area is widened along the movement direction f of the oxygen introduced through the inlet 121 . The body 123 may be provided in a shape close to a cylinder in appearance, and may be provided in a shape in which a circumference is widened from the inlet part 121 side toward the first contact part 125 .

The first contact portion 125 is a portion in contact with the patient's face, and various materials may be employed. For example, it may be formed of a material such as silicon to minimize the feeling of foreign body when in contact with the patient's face, and when oxygen is supplied to the patient through a mask, between the end of the first contact part 125 and the patient's face In order to prevent the supplied oxygen from leaking, a material capable of increasing adhesion may be adopted.

The mask cover 100 surrounds the mask 120 including the area in contact with the mask 120 on the patient's face, and can prevent oxygen supplied to the patient through the mask 120 from leaking to the outside. .

The mask cover 100 may include a connection part 111 , a binding ring 112 , a cover part 113 , and a second contact part 115 .

The connection part 111 may be provided to surround the circumference of the inlet part 121 . Therefore, the circumference of the connection part 111 may be provided in a shape corresponding to the outer circumferential surface of the inlet part 121 .

The binding ring 112 may be provided to surround at least a portion of the connection part 111 . The binding ring 112 may be provided in a ring shape of an elastic material, and may serve to fix the connection part 111 to be in close contact with the outer circumferential surface of the inlet part 121 .

More specifically, the cover part 113 may be provided to extend from the connection part 111 in a direction in which the cross-sectional area is widened. The cover part 113 may be provided in a shape in which the cross-sectional area is widened along the movement direction f of the oxygen introduced through the inlet part 121 . The cover part 113 may be provided in a shape close to a cylinder in appearance, and may be provided in a shape in which a circumference is widened from the connection part 111 side toward the second contact part 115 .

The second contact part 115 may be connected to an end of the cover part 113 to contact the patient's face. The second contact portion 115 may form a larger area than the first contact portion 125 . More specifically, the first contact portion 125 may form a first area capable of covering the respiratory portion (nose and mouth portion) of the patient's face, and the second contact portion 115 may be the first contact portion. A second area larger than the first area may be formed to include the facial area of the patient covered by 125 .

The second contact portion 115 is a portion in contact with the patient's face, and various materials may be employed. For example, it may be formed of a material such as silicon to minimize the feeling of foreign body when in contact with the patient's face, and when oxygen is supplied to the patient through a mask, between the end of the second contact part 115 and the patient's face In order to prevent the supplied oxygen from leaking, a material capable of increasing adhesion may be adopted.

The effect of BVM application can be increased by preventing oxygen leakage between the mask 120 and the patient's face through the mask cover 100 . More specifically, when performing ventilation with BVM, a technique called 'EC clamp technique' can be used to hold the ventilation part with one hand and hold the chin with the other hand to adhere the mask part of the BVM.

The 'EC clamp technique' technique uses the third, fourth, and fifth fingers of one hand to make an E to raise the chin, and the remaining first and second fingers to form a C shape to adhere the mask. Factors that can increase the effectiveness of BVM in this technique may be the proficiency of the practitioner and fixation of the finger position. This is because, for example, the operator can open the airway only by lifting the chin with the part of the E-shaped finger holding the position, and when the airway is opened, air can be ventilated into the lungs. Therefore, there may be a problem of air leaking between the masks that are not in close contact because relatively C is not provided properly.

In the present embodiment, when the mask cover 100 is applied, oxygen leakage is prevented, thereby preventing oxygen leakage between the mask 120 and the patient's face, thereby enhancing the effect of BVM application.

The mask cover 100 may further include flow passages 1141 and 1143 and discharge ports 1142 and 1144 .

The flow passages 1141 and 1143 may be formed between the outer surface of the body 123 and the inner surface of the cover 113 to form a passage through which oxygen moves. More specifically, the oxygen f introduced through the inlet 121 may be discharged to the outer surface of the body 123 through a hole formed between the inlet 121 and the body 123 .

Oxygen discharged through the holes may move in a first direction f21 and a second direction f22, respectively, and the first direction f21 corresponds to one side of the outer surface of the body 123 and the cover part 113 . It may refer to a direction toward the first outlet 1142 through the first flow path 1141 formed between the inner surfaces of the . The second direction f22 may refer to a direction toward the second outlet 1144 through the second flow path 1143 formed between the other side of the outer surface of the body 123 and the inner surface of the cover part 113 . have.

And, among the incoming oxygen f, the oxygen that branches in the first direction f21 and the second direction f22 and then moves in the direction f1 toward the body 123 may be directly supplied to the patient. . The amount of oxygen branched in the first direction f21 and the second direction f22 is the oxygen f introduced through the inlet 121 is formed between the inlet 121 and the body 123 . It can be controlled by the size of the hole.

Oxygen discharged to the outside of the mask cover 100 through the discharge ports 1142 and 1144 may be delivered to the support member 130 through hoses 141 and 142 to be described later, which will be described later.

When oxygen is supplied to the patient by applying BVM, effective ventilation can be provided only when the patient takes the sniffing position. This is because, in the sniffing position, the patient's airway is opened.

In the conventional case, as described above, the effect of supplying oxygen to the patient through the BVM may vary depending on the skill level of the operator, but there is a problem that the patient's posture fixation may also vary depending on the skill level of the operator. In the present embodiment, the influence of the skill of the practitioner can be minimized through the support member 130 and the patient's posture can be fixed, thereby providing effective ventilation.

The support member 130 may include a first support surface 131 , a second support surface 132 , and a variable part 133 . The first support surface 131 may support the cervical spine portion of the patient. The second support surface 132 may support at least a portion of the scapula muscle of the patient. That is, the above-described sniffing position can be maintained by supporting at least a portion of the patient's cervical vertebrae, a portion where the cervical vertebrae are connected to the scapula, and the scapula muscle by the first support surface 131 and the second support surface 132 .

The variable part 133 may be made of a material that can be contracted and expanded. As oxygen is supplied through the hoses 141 and 142 , the variable part 133 may be expanded. As the variable part 133 expands, the second support surface 132 forms a predetermined inclination angle with the first support surface 131 and may move in a direction in which the volume of the support member 130 increases.

As the second support surface 132 forms a predetermined inclination angle with the first support surface 131 , it may correspond to the above-described shape of the cervical spine and sphincter of the patient. The second support part 132 corresponds to the shape of the sphincter of the patient, and various materials that can expand in the direction of increasing the volume of the support member 130 may be employed.

As the support member 130 is supplied with oxygen through the hoses 141 and 142 and expands, the second support surface 132 may come into contact with at least a portion of the scapula muscle of the patient, and according to the above-described structure, it can be applied to the body of the patient. It is not limited and can effectively support the cervical spine and scapular region of the patient.

Meanwhile, the hoses 141 and 142 may form flow paths 1410 and 1420, respectively. The hose may include a first hose 141 and a second hose 142, and a flow path 1410 through which oxygen moves may be formed in the first hose 141, and the second hose A flow path 1420 through which oxygen moves may also be formed inside the 142 .

The first hose 141 may be connected to the first outlet 1142 so that the flow path 1410 of the first hose may communicate with the first flow path 1141 . In addition, the second hose 142 may be connected to the second outlet 1144 so that the flow path 1420 of the second hose may communicate with the second flow path 1143 .

Since each hose communicates with the first flow path 1141 and the second flow path 1143 by the above-described structure, the support member 130 may be expanded by receiving oxygen through the hose.

The hoses 141 and 142 may be made of a material capable of contracting and expanding. The oxygen supply apparatus of this embodiment can supply oxygen to the support member 130 through the hoses 141 and 142 and maintain the mask 120 and the mask cover 100 in close contact with the patient's face. More specifically, the hoses 141 and 142 are made of a rubber-like material, so that the BVM device is in close contact with the patient's face by closely fixing the cervical vertebrae and the scapula side to the patient's face according to the patient's head circumference or neck circumference. You may be able to fix it with
