Problems solved by technology

Since this method cannot accurately determine the fastening force of the four ends of the mask, the problem of air leakage often occurs
Although using a larger fastening force can avoid air leakage, it will cause discomfort to the patient, cause damage to the face, and affect the surgical experience
The inventor's application number is CN202110864614.4, and the Chinese invention patent application titled "mask fastening system and anesthesia airway auxiliary management device" uses electric drive to shrink the drawstring to compress the mask, which greatly solves the problem of the existing technology. The problem of mask air leakage or poor patient experience, but in a large number of simulation experiments by the inventor, the phenomenon of mask air leakage still occurs in a small number of cases
In the actual operation process, once the mask leaks, it needs to be fixed manually, which wastes medical manpower, and if it is not found in time or not found, it may lead to the failure of anesthesia and increase the risk of surgery

Embodiment 1

[0050] Such as Figure 3~6 As shown, the present invention provides a mask fixing device to solve the above problems, including: a mask body 100, a fixing part 200 and a stay cord 130; the mask body 100 is provided with a base 110, and the fixing part 200 is fixedly arranged on the base 110 And there are at least two working states, the drawstring 130 passes through the fixing part 200, so that when the drawstring 130 is tightened, the mask body 100 fits with the face of the human body to ensure sealing; wherein, when the fixing part 200 is in the first working state , the drawstring 130 slides relative to the mask body 100. When the fixing part 200 is in the second working state, the drawstring 130 is fixed relative to the mask body 100. The first working state refers to the state in which the drawstring 130 is tightened. The second working state refers to the state in which the pull rope 130 is fully tensioned. For the above scheme, please refer to figure 1 , the drawstrin...

Embodiment 2

[0064] The difference between this embodiment and the first embodiment lies in that the fixing method between the pressing plate 223 and the base body 210 is different. The first embodiment adopts a locking knob to fix the pressing plate 223 , while the present embodiment uses a clamping structure to fix the pressing plate 223 . Specifically, such as Figure 8 As shown, a mounting plate 218 is provided on one side of the base body 210 , a clip 219 is provided on the mounting plate 218 , and a buckle 224 adapted to the clip 219 is provided on the pressing plate 223 . The upper end of the clip 219 is provided with a slope, which is convenient for the clip 219 to be inserted into the buckle 224. At the same time, the clip 219 has a certain degree of flexibility, and the medical personnel can move the clip 219 to make it escape from the buckle 224, so as to open the pressing plate 223 . Certainly, the positions of the clip 219 and the buckle 224 can be interchanged, that is, the ...

Embodiment 3

[0066] The difference between this embodiment and the first or second embodiment is that the mask is not a conventional medical oxygen mask, but a medical oxygen mask with a specific base. Such as Figure 9 As shown, the base body 210 is integrally formed with the base 110 , that is, the fixing part 200 is integrally formed on the mask. Since both are plastic parts, the base body 210 and the base 100 can be manufactured by injection molding process, which is simple and convenient. This embodiment simplifies the assembly process, and it is no longer necessary to install the base body 210 with the structure of the claw and ferrule 211 in the first or second embodiment, which makes the use of the medical staff more convenient. Of course, the integrally formed base body 210 and base 110 can also be regarded as being connected through the connecting portion 120 , and the content of this embodiment should also be included in the protection scope of the claims.

Abstract

The invention relates to the technical field of medical instruments, in particular to a mask fixing device which comprises a mask body, and the mask body is provided with a base; a fixing part is fixedly arranged on the base and has at least two working states; a pull rope penetrates through the fixing part, so that after the pull rope is tensioned, the mask body is attached to the face of the human body, and sealing is guaranteed; and when the fixing part is in the first working state, the pull rope slides relative to the mask body, and when the fixing part is in the second working state, the pull rope is fixed relative to the mask body. According to the mask fixing device, it is guaranteed that the mask is attached to the face of the human body through the pull rope, then the pull rope and the mask are fixed through the fixing part of the pull rope installed on the mask, and the structure is convenient to install and suitable for a common medical oxygen mask.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a mask fixing device and an anesthesia airway auxiliary management device having the same. Background technique [0002] Mask ventilation belongs to non-invasive positive pressure ventilation (NPPV). The advantages of mask ventilation include: the airway management method is less irritating to the patient and the patient is more comfortable; it can avoid the destruction of the normal barrier function of the upper airway caused by the establishment of an artificial airway, Injury, respiratory infection and other complications. The use of anesthesia airway auxiliary management devices with mandibular lifting function to implement face mask ventilation can be used for acute and chronic respiratory failure caused by various reasons, effectively relieve dyspnea, strengthen gas exchange and improve oxygenation function, and shorten ICU stay and total length of hospital stay, r...
