Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to an intubation type anesthesia mask. Background Art

[0002] At present, the anesthesia mask used for inserting the inspection tube for general anesthesia of the patient in the clinic generally has an oxygen inhalation port and an inspection channel arranged on the mask body, and an annular closed air bag is arranged at the lower end of the mask body.

[0003] When inspection tubes of different specifications and diameters are used, or when emergency gastric lavage or other surgical procedures involving inserting a gastric tube are performed, the inspection tube has a variable diameter section. There is a difference in the aperture of the inspection channel and the inspection tube, and there is a gap or close contact between the two, resulting in a poor seal. At this time, the gas in the mask will leak out from the gap, causing poor oxygen pressure in the mask and often leading to medical accidents. Utility Model Content

[0004] The utility model aims at the deficiencies of the prior art and provides an intubation type anesthesia mask which effectively solves the problem that the inspection channel and the inspection tube in the prior art have different apertures, there is a gap or close contact between the two, and the seal is not tight, and the gas in the mask will leak out from the gap.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is:

[0006] An intubation anesthesia mask comprises a mask, an air bag is arranged at the lower end of the mask, an oxygen inhalation tube is arranged at the front end of the mask, a cover plate is arranged at the upper end of the mask, a placement hole is opened in the middle of the cover plate, a sealing ring is arranged in the placement hole, a tube inlet cone block is arranged in the sealing ring, a cross intersection is opened inside the tube inlet cone block, an inspection tube is arranged in the cross intersection, an elastic clamp component is coaxially arranged on the upper end of the sealing ring, and the elastic clamp component includes a pair of extrusion blocks corresponding to the tube inlet cone block.

[0007] The pipe inlet cone block is made of rubber material with good elasticity, and the pipe inlet cone block is thin at the upper end and thick at the lower end.

[0008] The elastic clamping component also includes a ring shaft block coaxial with the upper end of the sealing ring, a pair of sliding columns are respectively arranged on the circumferential outer wall of the ring shaft block, and a spring connected to the sliding column sleeve is arranged between the ring shaft block and the extrusion block.

[0009] The extrusion blocks are symmetrically arranged and symmetrical in the middle section of the arc-shaped gap at the cross intersection.

[0010] Front hanging ears are respectively arranged on both sides of the front end of the cover plate, and rear hanging ears are respectively arranged on both sides of the rear end of the cover plate.

[0011] The airbag is an annular closed airbag.

[0012] Compared with the prior art, the utility model has the following advantages:

[0013] 1. Insert the inspection tube into the cross intersection opened by the tube inlet cone block. The tube inlet cone block can seal and clamp the inspection tube. Since the tube inlet cone block is elastic, it can accommodate inspection tubes of different shapes, and the two have a strong fit, which can effectively prevent leakage.

[0014] 2. The extrusion block can extrude the pipe inlet cone block. Since the pipe inlet cone block is made of rubber, the extrusion block can deform the pipe inlet cone block under the action of spring force, thereby sealing the pipe inlet cone block and the inspection pipe.

[0020] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0021] like Figure 1-4 As shown, an intubation anesthesia mask comprises a mask 1, an air bag 2 is arranged at the lower end of the mask 1, an oxygen inhalation tube 6 is arranged at the front end of the mask 1, a cover plate 5 is arranged at the upper end of the mask 1, a placement hole is opened in the middle of the cover plate 5, a sealing ring 7 is arranged in the placement hole, a tube inlet cone block 9 is arranged in the sealing ring 7, a cross intersection 10 is opened inside the tube inlet cone block 9, an inspection tube 14 is arranged in the cross intersection 10, an elastic clamp component is coaxially arranged on the upper end of the sealing ring 7, and the elastic clamp component includes a pair of extrusion blocks 12 corresponding to the tube inlet cone block 9.

[0022] When the utility model is in use, the mask 1 is fixed on the patient's face, the airbag 2 is attached to the patient's facial skin, the sealing ring 7 is fixed in the hole of the cover plate 5, the tube inlet cone block 9 is sealed and fixed in the sealing ring 7, and the tube inlet cone block 9 and the mask 1 are communicated with each other, and the inspection tube 14 is inserted into the cross intersection 10 opened by the tube inlet cone block 9. The tube inlet cone block 9 can seal and clamp the inspection tube, and because the tube inlet cone block 9 is elastic, it can accommodate inspection tubes 14 of different shapes, and the two have strong fit, which can effectively avoid leakage, and the elastic clamping component includes a pair of extrusion blocks 12, and the extrusion block 12 can squeeze the tube inlet cone block 9 to ensure that the fit between the tube inlet cone block 9 and the inspection tube 14 is better.

[0023] The pipe inlet cone block 9 is made of rubber material with good elasticity, and the pipe inlet cone block 9 is thin at the upper end and thick at the lower end.

[0024] like Figure 1 and 2 As shown, the inspection tube 14 can be inserted into the cross intersection 10 of the tube inlet cone block 9. Since the tube inlet cone block 9 is made of rubber material and has tightness, the connection between the inspection tube 14 and the tube inlet cone block 9 can be fitted according to the shape of the inspection tube 14.

[0025] The elastic clamping component also includes a ring shaft block 8 coaxial with the upper end of the sealing ring 7, and a pair of sliding columns 11 are respectively provided on the circumferential outer wall of the ring shaft block 8. A spring 13 connected to the sliding column 11 is provided between the ring shaft block 8 and the extrusion block 12.

[0026] like Figure 1 and 3 As shown, the sliding column 11 can slide along the inner wall of the ring shaft block 8, and the extrusion block 12 can extrude the inlet cone block 9. Since the inlet cone block 9 is made of rubber, the extrusion block 12 can deform the inlet cone block 9 under the action of the elastic force of the spring 13, thereby sealing the inlet cone block 9 and the inspection tube 14.

[0027] The extrusion blocks 12 are symmetrically arranged and are symmetrical about the middle section of the arc-shaped gap at the cross intersection 10 .

[0028] like Figure 3 and 4 As shown, the extrusion block 12, under the action of the spring 13, squeezes the pipe inlet cone block 9 to facilitate sealing the cross intersection 10.

[0029] Front hanging ears 3 are respectively arranged on both sides of the front end of the cover plate 5 , and rear hanging ears 4 are respectively arranged on both sides of the rear end of the cover plate 5 .

[0031] The airbag 2 is an annular closed airbag 2.

[0032] like Figure 1 and 2 As shown, the airbag 2 can be compressed and fit around the patient's mouth and nose, which can improve comfort on the one hand and prevent gas leakage on the other.

[0033] The working process of the utility model is as follows: when the utility model is in use, the mask 1 is fixed on the patient's face, and the airbag 2 is attached to the patient's facial skin. The airbag 2 can be compressed and attached around the patient's mouth and nose, which improves comfort on the one hand and avoids gas leakage on the other hand. The sealing ring 7 is fixed in the hole of the cover plate 5, and the tube inlet cone block 9 is sealed and fixed in the sealing ring 7, and the tube inlet cone block 9 is communicated with the mask 1. The inspection tube 14 is inserted into the cross intersection 10 opened by the tube inlet cone block 9, and the tube inlet cone block 9 can seal and clamp the inspection tube 14. Since the tube inlet cone block 9 is made of rubber material and has tightness, the connection between the inspection tube 14 and the tube inlet cone block 9 is fitted according to the shape of the inspection tube 14, and the fit between the two is strong, which can effectively avoid leakage.

[0034] The sliding column 11 can slide along the inner wall of the ring shaft block 8, and the extrusion block 12 can extrude the inlet cone block 9. Since the inlet cone block 9 is made of rubber, the extrusion block 12 can deform the inlet cone block 9 under the action of the elastic force of the spring 13, thereby sealing the inlet cone block 9 and the inspection tube 14.

[0035] The front hanging ears 3 and the rear hanging ears 4 are respectively used to connect fixing belts, and the fixing belts are used to facilitate fixing the mask 1 on the patient's face.
