Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In order to explain the technical solution of the present invention, the following description is made by using specific examples.
Fig. 1 shows the structure of a disposable low resistance positive pressure oxygen supply mask for painless gastroscopy according to an embodiment of the present invention, and only the parts related to the embodiment of the present invention are shown for convenience of illustration.
As shown in fig. 1, 2, the oxygen face guard is given with low resistance malleation to disposable painless gastroscope examination that this embodiment provided includes the cover body 1, there is round gasbag 2 cover body 1 bottom, the intercommunication has inflation inlet 21 on the gasbag 2, cover body 1 front portion intercommunication has air supply interface tube 11, cover body 1 top part undercut forms wide-mouth 12, trompil and downwardly formed gastroscope mouth 13 in wide-mouth 12 bottom, gastroscope mouth 13 just has a take the altitude for tubular structure, and gastroscope mouth 13 internal diameter is greater than the diameter of gastroscope pipe, the pipe wall of gastroscope mouth 13 is hollow out structure, set up round mantle 3 downwards from the top in the gastroscope mouth 13, mantle 3 wears out the gastroscope mouth and is connected with round spacing ring 4 bottom, spacing ring 4 external diameter is greater than gastroscope mouth 13 internal diameter.
In this structure, the gasbag is the position that face guard and patient face laminated mutually, mainly for better laminating patient's face, prevents air leakage during the positive pressure ventilation. The inflation inlet is used for inflating the air bag. The gas source mouthpiece is connected with oxygen sources such as a breathing machine, an anesthesia machine or a breathing bag and the like to supply oxygen to the mask. The wide mouth is a sunken structure with the caliber larger than the mouth of the gastroscope. In addition, as a preferable structure, the mask of the embodiment further comprises a plug 5 connected to the mask body 1, and the plug 5 is used for being plugged into the wide opening to play a sealing role. The gastroscope mouth is the tubulose and has certain height, and the diameter of gastroscope mouth is greater than the diameter of clinical gastroscope pipe, and the doctor of being convenient for lets in the gastroscope pipe in proper order in gastroscope mouth, patient's oral cavity, patient's esophagus finally to the stomach of patient. The side wall of the gastroscope opening is of a hollow structure, and as shown in the figure, the pipe wall of the gastroscope opening is provided with a plurality of vertical notches along the height direction, so that oxygen in the mask can penetrate through the notches to enter the gastroscope opening.
The soft film is a soft film, is provided with a circle and can be made of materials such as latex, rubber, silica gel, polyurethane, composite nano plastic and the like. As shown in figure 2, the upper end of the soft membrane is connected with the edge of the upper port of the gastroscope opening, and the bottom of the soft membrane penetrates out of the gastroscope opening and is connected with a limiting ring. The outer diameter of the limiting ring is larger than the inner diameter of the gastroscope opening, the material is tough, the limiting ring is used for limiting the soft membrane to move upwards, the soft membrane is prevented from being completely sunk into the gastroscope opening, and otherwise, the soft membrane cannot play a role in isolating oxygen.
In this embodiment, the cover and the gastroscope opening may be independently arranged, or may be integrally formed, preferably integrally formed, so as to reduce the production and installation costs. However, as a preferable structure, as shown in fig. 3, the top of the gastroscope opening 13 is provided with a ring of top ring 6, and the soft membrane 3 is connected between the top ring 6 and the stop ring 4, because the process of connecting the soft membrane top end to the upper port of the gastroscope opening is complicated and the cost is high. Like this mantle and apical ring, the spacing ring is structure as an organic whole, the production of being convenient for, with spacing ring extrusion deformation during the use, then penetrate from the gastroscope mouth, wear out from the gastroscope mouth until the spacing ring, as an optimal structure, the external diameter and the wide-mouth bore of apical ring are unanimous, the apical ring can block in the wide-mouth bottom, promptly block port on the gastroscope mouth, oxygen is from entering into the intraoral back of gastroscope, basically can not upwards spill over, most oxygen still flows down along the mantle, oxygen that keeps the face guard intracavity is the malleation state, in order to supply the patient to breathe.
In addition, in order to facilitate wearing, as shown in fig. 5, the cover body is further connected with a fixing belt 7. In this structure, fixed band 7 can be dismantled, cover body top symmetry is provided with connecting bolt 14, fixed band 7 both ends cyclization and cover are on the connecting bolt 14 of corresponding side. In addition, the middle position of the fixing band 7 is overlapped and sleeved with a rubber sleeve 8 to adjust the effective length of the fixing band.
The use method of the mask comprises the following steps:
firstly, the air bag is inflated through an inflation port, the wide port is plugged by a plug when anesthesia induction is carried out (namely before gastroscopy), and an air source connector tube is connected with a breathing machine, an anesthesia machine or a breathing bag to supply oxygen to a patient. After the anesthesia is successful, the plug is taken down, the gastroscope catheter is placed into the oral cavity of a patient through the gastroscope opening, a proper amount of paraffin oil is injected into the wide-mouth part to lubricate the outer wall of the gastroscope catheter, the gastroscope catheter is continuously inserted, and finally the gastroscope catheter reaches the stomach of the patient through the esophagus for examination. During gastroscopy, the face guard intracavity is full of oxygen, and pressure is higher than atmospheric pressure, and oxygen enters into in the gastroscope mouth and oppresses the mantle through the fretwork notch of gastroscope mouth, and the mantle atress is hugged closely gastroscope pipe outer wall, and then realizes sealed face guard, has guaranteed the malleation state of face guard intracavity, is favorable to maintaining patient's oxygen supply.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
