Description

TECHNICAL FIELD

[0001] The utility model relates to medical equipment technical field, concretely relates to anesthesia mask pipeline periphery aperture sealing device. BACKGROUND

[0002] During the operation anesthesia process, the patient usually has respiratory depression after anesthesia, needs to use the anesthesia mask to carry out artificial ventilation, or when the patient appears dyspnea and other emergency situations, uses the anesthesia mask to carry out pressurized oxygen supply to the patient, establishes temporary artificial respiratory passage and saves time for the patient rescue. During the operation or postoperative nursing process, in order to guarantee the nutrition supply or gastroesophageal drainage, part of the patients usually have a stomach tube or enteral nutrition tube, or like the patients with lung diseases, heart failure and other diseases, the human body cannot obtain enough oxygen, needs to provide additional oxygen through the nasal tube oxygen inhalation, the naked stomach tube, nutrition tube or oxygen inhalation tube has a certain diameter, so that the anesthesia mask cannot perfectly fit the patient's facial skin and has a larger gap, which causes a certain proportion of air leakage in the anesthesia mask auxiliary breathing process, that is, the oxygen supplied in the anesthesia mask cannot be fully and efficiently supplied to the patient, which affects the auxiliary breathing effect.

[0003] The existing anesthesia mask pipeline periphery aperture sealing device mainly has: (1) a through hole capable of passing through the stomach tube is formed on the anesthesia mask, so that the stomach tube can pass through; this setting mode needs to remove the negative pressure suction ball fixed at the tail end of the stomach tube when the anesthesia mask and the stomach tube are separated, so that the anesthesia mask can be removed, which is easy to cause stomach fluid leakage and pollution. (2) recesses through which the stomach tube can pass are arranged on the bottom of the side edge of the anesthesia mask; the above two intubation fixing devices need other devices to seal the through holes or recesses on the anesthesia mask when the intubation is not needed, so that the anesthesia mask has poor universality. (3) triangular, trapezoidal, M-shaped and other fixing devices are placed on the bottom of the side edge of the anesthesia mask, and a channel through which the intubation tube passes is formed on the fixing device. Since the intubation tube and the device often have a certain slope during actual use, if the angle of the device is adjusted to adapt to the intubation tube, the device cannot be attached to the bottom of the anesthesia mask, causing air leakage.

[0004] Therefore, an anesthesia mask air-tight and universal intubation fixing device is still needed to solve the above technical problems. UTILITY MODEL CONTENTS

Furthermore, phrases such as “one element on / below another element” can indicate that the two elements are in direct contact, or that the two elements are integral or that there are other elements between them.

[0035] Example

[0036] like Figures 1-9 As shown, this embodiment provides a device for sealing the pores around the tubes of anesthesia masks, including a sealing body 100 and a tube channel 200 disposed within the sealing body.

[0037] An anesthesia mask typically consists of a transparent mask body and a connecting tube. The mask body is usually made of elastic material to fit the patient's face and prevent gas leakage. The connecting tube is used to connect the mask body to the anesthesia machine or oxygen supply equipment to deliver anesthetic drugs or oxygen into the mask.

[0038] This embodiment uses a gastric tube as an example for external insertion. The principle is the same when the insertion tube is a feeding tube, nasal oxygen tube or other catheter, only the size and angle of the insertion tube are slightly different. This device can also be used, so it will not be described in detail.

[0039] The sealing body 100 of this device includes a sealing body 110 and an annular seat 120 connected to its lower end. The sealing body 110 is a rotating structure with an arc-shaped cross-section, which can be parabolic, circular, or other shapes. Its streamlined structure further reduces the possibility of gaps forming between the sealing body and the anesthesia mask, improving airtightness. The annular seat 120 is a cylinder, preferably with a diameter of 25-40 mm and a height of 1-3 mm, and is disc-shaped. Together with the annular seat 120, it forms a rotating structure resembling a nipple. The sealing body 110 includes a sealing head 111 and a connecting portion 112 located below it. The sealing head 111 is an upwardly convex spherical structure, and the connecting portion 112 is an arc-shaped frustum structure with outward or inward convex sides. The connection between the sealing head 111 and the connecting portion 112 is a smooth transition. Preferably, the connecting portion 112 has an inwardly concave arc-shaped frustum structure to improve the sealing performance of the contact surface between the anesthesia mask and the sealing body 100. The total height of the sealing body 100 is preferably 5-8 mm.

[0040] The annular seat 120 is connected to the connecting part 112 of the sealing body. Preferably, the side arc of the connecting part 112 is tangent to the upper surface of the annular seat 120, so that the transition at the connection between the two is smoother and more conducive to sealing.

[0041] The pipeline passage 200 is a groove structure arranged at the bottom of the sealing body 100. The size of the groove can be customized according to the diameter of the cannula. The cross section of the groove can be circular arc, U-shaped, 1 / 2 circle, 3 / 4 circle, etc. and can be set as needed. In this application, the "circle" in the 1 / 2 circle and the 3 / 4 circle refers to the cross-sectional circle of the inserted catheter. The size of the groove is slightly smaller than the diameter of the cannula, and the two are in interference fit to make the fit more compact.

[0042] Preferably, the cross section of the groove is 3 / 4 of the cross section of the cannula, which can better cover the cannula and have better clamping and fixing effect and better sealing effect.

[0043] Further, when the cross section of the groove is U-shaped, the arc segment is a semicircle with a radius that is the same as or approximately the same as the radius of the cannula, and the vertical segment height is preferably 1 / 3-1 / 2 of the radius of the cannula.

[0044] The number of pipeline passages 200 can be one, two or more, which can be set according to actual needs. When the pipeline passage is one, it is located at the center of the bottom of the sealing body. When the pipeline passage is multiple, it is preferably uniformly distributed at the bottom of the sealing body.

[0045] The pipeline passage 200 can be a straight line passage or an arc line passage in the horizontal direction. The straight line passage is a straight line groove through the sealing body, and the arc line passage is an arc line groove through the sealing body, which can be set according to actual needs.

[0046] Preferably, the arc a of the arc line groove is 80-120 degrees, which can adapt to the arc of most actual applications of fixing the gastric tube. All the arc a of the groove above refers to the arc of the arc between the two intersection points of the center line of the arc line groove and the outer diameter of the annular seat.

[0047] Preferably, the sealing head 111 and the connecting part 112 of the sealing body are integrally formed.

[0048] The material of the sealing body 100 is made of soft elastic material, which is beneficial to the tight adhesion of the cannula to the edge and inner wall of the groove. The material of the sealing body 100 can be silicone rubber, thermoplastic elastomer, plastic, latex, etc. For example, ABS (acrylonitrile-butadiene-styrene), PETG (polyethylene terephthalate), Nylon, TPU (thermoplastic polyurethane) and other materials can be used for 3D printing, or silicone, latex or natural rubber and other materials can be used for traditional mold injection processing method production. The above materials have good elasticity and support, so that the sealing body 100 can fully fit the patient's face and the anesthesia mask, thereby achieving excellent anti-leakage effect.

[0049] Preferably, the sealing body 100 is made of TPU material, TPU is a thermoplastic polyurethane elastomer, which is elastic between rubber and plastic, the material is soft and has high strength and high toughness, and the softness of TPU material is better than that of traditional plastic material, which can better adapt to objects of different shapes. Compared with other materials, TPU material has many advantages in 3D printing, it has good interlayer bonding force, can make articles with excellent mechanical properties, and is very suitable for the manufacturing method of 3D printing in the embodiment.

[0050] Further, the sealing body 110 and the annular seat body 120 can be integrally formed or in a split structure, which can be fixed by bonding.

[0051] Further, the sealing body 110 and the annular seat body 120 can be made of the same or different materials. When different materials are used, the annular seat body 120 can be made of softer material, such as gel, latex, etc., so that the sealing effect will be better.

[0052] Further, an arc-shaped sealing gasket layer 300 is arranged on the inner surface of the pipeline channel 200 of the sealing body, which is a sheet. The sealing gasket layer 300 is located between the pipeline channel 200 and the cannula, and is used to better seal the cannula and the pipeline channel 200. The material of the sealing gasket layer 300 is lower in hardness and better in elasticity than the material of the sealing body 100, and is more easily adhered. Preferably, the hardness of the material of the sealing gasket layer 300 is Shore A 10-30 degrees, and the hardness of the material of the sealing body 100 is Shore A 40-80 degrees. Preferably, the material of the sealing gasket layer 300 is gel. Gel is a semi-solid material with elasticity formed by increasing the viscosity of a high molecular solution or sol under certain conditions, which has better skin-friendliness and sealing effect. The length and shape of the sealing gasket layer 300 are adapted to the pipeline channel 200, and preferably it can completely adhere to and cover the inner surface of the pipeline channel 200.

[0053] Further, the size of the sealing gasket layer 300 is not limited, as long as it can completely cover the inner surface of the pipeline channel 200. The developed view of the sealing gasket layer 300 can be rectangular, or can be developed Figure 1 .

[0054] In use, the patient's nose is inserted with a gastric tube, the gastric tube is embedded from the bottom of the groove, and when the anesthetic mask is pressed downward, the gastric tube is squeezed in the groove, and because the gastric tube and the groove are both made of elastic material, the gastric tube and the groove are more closely fitted, and because the human face skin has elasticity, the gastric tube, the groove and the patient's face are mutually fitted, ensuring the sealing effect of the anesthetic mask. When the pressurized ventilation ends and needs to be removed, only the anesthetic mask is removed, the sealing body is removed, and then the gastric tube is pulled out from the patient's body, and the above-mentioned process of moving the anesthetic mask and the sealing body will not affect the position of the gastric tube, which can effectively avoid the gastric tube displacement, gastric tube internal material leakage and pollution caused by pulling and moving in actual operation, and ensures the safety of the operation.

[0055] In order to prevent the gastric tube from being bent, the angle of the pipeline passage 200 in the sealing body can be adjusted at any time to make the gastric tube pass through the pipeline passage 200 more smoothly, so that no bending occurs. Because the sealing body 100 is a rotating body structure, no matter how it is rotated, it will not affect the contact sealing between the anesthetic mask and the sealing body 100, and the existing anesthetic mask fixing device is generally a non-rotating body structure such as a triangular, trapezoidal, M-shaped structure, which cannot be rotated at will, otherwise the sealing between the anesthetic mask and the fixing device will be not tight, which limits the adjustment of the pipeline passage angle and causes inconvenience in actual use.

[0056] The sealing body can be made by traditional manufacturing method or by 3D printing technology, preferably by 3D printing technology, in terms of traditional manufacturing, the more complex the shape of the object, the higher the manufacturing cost, 3D printing can make the parts integrated molding, without assembly, and can adjust the size and shape at any time, and can be personalized, which can save time and cost.

[0057] Although the present application has been described with reference to the example embodiments, it should be understood that the present application is not limited to the disclosed example embodiments. Various adjustments or changes can be made to the example embodiments of the present application without departing from the scope or spirit of the present application. The scope of the claims should be based on the broadest interpretation to encompass all modifications and equivalent structures and functions.
