Description

Technical Field

[0001] The utility model relates to the field of ventilation masks, in particular to a ventilation mask that can be adapted to a gastric tube. Background Art

[0002] The number of general anesthesia surgeries in my country has increased year by year in recent years. Patients undergoing general anesthesia routinely use ventilation masks for assisted breathing, and some also require the use of a gastric tube. Due to the influence of the gastric tube, when the ventilation mask is placed over the patient's mouth and nose, it cannot maintain a good airtightness during positive pressure ventilation, making it difficult to maintain blood oxygen. In clinical practice, anesthesiologists make advance interventions based on clinical experience, such as making homemade objects to plug leaks or using expensive custom masks, but this inevitably increases clinical workload and costs. Utility Model Content

[0003] In view of the technical problems existing in the prior art, the purpose of the present utility model is to provide a ventilation mask that can be adapted to a gastric tube, which is convenient for quickly fixing the gastric tube when the ventilation mask is put on clinically and ensures good air tightness of the ventilation mask.

DETAILED DESCRIPTION

[0027] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Example 1

[0029] like Figures 1-6 As shown, a ventilation mask adaptable to a gastric tube, similar to a non-inflatable, edge-type mask, comprises a mask body 1, a sealing cushion, and a respiratory interface 2 located in the middle of the mask body 1. The annular sealing cushion is adapted to the bottom edge of the mask body 1. The non-inflatable sealing cushion includes a rolled-edge cushion 3 that is rolled up inside the mask body 1 and defines a gastric tube hole 4 near the face of a patient 14. The ventilation mask also includes a plug 5 that is removably inserted into the gastric tube hole 4 for sealing. When a gastric tube 13 is to be fitted, an opening slit 6 is defined at the outer end of the gastric tube hole 4 toward the edge of the rolled-edge cushion 3. The gastric tube 13 can be inserted into the gastric tube hole 4 through the opening of the opening slit 6. The opening slit 6 is then assembled to fit the patient 14's face, ensuring good airtightness of the ventilation mask. This opening slit 6 facilitates the gastric tube hole 4 to accommodate gastric tubes 13 of various diameters.

[0030] An easy-tear mark 16 that is easy to tear open by hand is set from the outer end of the gastric tube hole 4 to the edge of the curled edge pad 3. The thickness of the easy-tear mark 16 is thinner than that of the curled edge pad 3, which is convenient for medical staff to tear it open easily by hand. Tearing along the easy-tear mark 16 by hand will form an open crack 6.

[0031] There are two gastric tube holes 4, corresponding to two stoppers 5, and two corresponding tear marks 16. The two gastric tube holes 4 are located on either side of the nose. When a gastric tube 13 is to be fitted, only one of the tear marks 16 is torn, and the gastric tube 13 is inserted into only one of the gastric tube holes 4, facilitating the gastric tube 13 to be extended from either the left or right side of the ventilation mask. A ventilation mask has only one opening slit 6.

[0032] Figure 4 and Figure 5 The ventilation mask has the chin end on the left side of the picture and the nose end on the right side of the picture.

[0033] The curling pad 3 is made of silicone or rubber, and is soft and can provide a good sealing effect.

[0034] The outer diameter of the stomach tube 13 commonly used in clinical practice is 4 mm, and the diameter of the stomach tube hole 4 is 4 mm.

[0035] like Figure 4 As shown, the plug 5 is connected to the mask body 1 via a lead 7, which prevents the plug 5 from being discarded. The plug 5 is made of silicone or rubber, and the lead 7 is also made of silicone or rubber. The soft plug 5 is wrapped by the crimping pad 3 and will not cause pressure marks on the patient's 14 facial skin.

[0036] The plug 5 includes a plug head 8, a sealing portion 9, and an introduction portion 10 connected in sequence. The introduction portion 10 is located in the stomach tube hole 4. The sealing portion 9, which is in an inverted cone shape, seals the stomach tube hole 4, and the plug head 8 is located above the stomach tube hole 4. The plug 5 is inserted into the stomach tube hole 4 through the introduction portion 10.

[0037] The breathing interface 2 is a cylindrical opening, and a fixing bracket is sleeved on the outside of the opening.

[0038] In this embodiment, the preferred fixing bracket includes a circular ring 11 and four headband buckles 12 fixed on the circular ring 11. The circular ring 11 is sleeved around the outer periphery of the through opening, and the headband buckles 12 are used to connect to the fixing belt tied around the head of the patient 14.

[0039] When the patient does not need a gastric tube, the plug is tightly plugged into the gastric tube hole to ensure the airtightness of the ventilation mask; when a gastric tube needs to be adapted, the gastric tube is inserted into the gastric tube hole from the opening of the opening crack to ensure good airtightness of the ventilation mask and maintain the patient's normal blood oxygen level. The operation is simple, fast and convenient, which reduces the workload of medical staff, meets the needs of anesthesia surgery, and effectively improves the success rate of the operation.

[0040] The implementation principle of the utility model: when the gastric tube 13 is not in use, the gastric tube hole 4 is plugged tightly by the plug 5 to ensure the airtightness of the ventilation mask; Figure 3As shown, when the ventilation mask needs to fit the gastric tube 13 led out from the nose 15 of the patient 14, because the tail end of the conventional gastric tube 13 is too large, the tail end of the gastric tube 13 cannot directly pass through the gastric tube hole 4. The medical staff needs to tear open an opening slit 6 through an easy-tear mark or cut it with scissors, and insert the gastric tube 13 into the gastric tube hole 4 from the opening of the opening slit 6 along the opening slit 6 inward. The medical staff then splices the opening slit 6 so that the rolled edge pad 3 at the spliced ​​opening slit 6 also fits the face of the patient 14, thereby achieving the ventilation mask fixing the gastric tube 13 while also ensuring good airtightness of the ventilation mask.

[0041] Example 2

[0042] The difference between this embodiment and the second embodiment is that the number of the gastric tube hole 4 of the ventilation mask is one, the gastric tube hole 4 is located on the left or right side of the nose, the number of the plug 5 is correspondingly one, and the number of the easy tear mark 16 is correspondingly one.

[0043] The above further describes the present invention with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the present invention.
