Abstract
The invention discloses a novel enclosed face mask, which comprises a mask body, wherein an enclosed pad is arranged on a lower edge of the mask body; a connecting pipe is connected to an upper top surface of the mask body; a hang strip ring is sleeved at the connecting pipe; a through hole is formed on the mask body; a sealing cover is arranged at the through hole; one part of the sealing cover is fixedly connected with an outer edge of the through hole and the other part of the sealing cover is arranged on the mask body through a fixing handle on the sealing cover, and a screw is arranged on a part corresponding to a fixing hole on the fixing handle; a nasal feeding tube hole is formed on the sealing cover; a nick is formed on the fixing handle; one end of the nick is communicated with the nasal feeding tube hole; and a gland matched with the nick is arranged at the nick. By the face mask, a stomach tube food injection end which is placed previously is pulled out of the face mask, air leakage at the stomach tube on the face mask and face compression are avoided during noninvasive ventilation, the conditions that the stomach tube is pulled out and noninvasive ventilation treatment is used in order to reduce the air leakage and lighten face compression are avoided, patients are actively rescued, and the workload of medical personnel is reduced.
Description
Technical field
The invention belongs to medical apparatus and instruments, relate in particular to a kind of airtight novel face shield.
Background technology
Mechanical ventilation technical development in nearly 10 years at present is very fast, individual various novel respirator constantly emerges, novel respirator is equipped with the noinvasive ventilating mode, assurance is to critical patient's effective ventilation treatment, but the inward mask leakage situation was unresolved always both at home and abroad when the nasal feeding patient was carried out the ventilation of airtight noinvasive, though developed various face shields, all unresolvedly insert nasal feeding tube earlier as the patient, the problem of inward mask leakage and facial compressing when carrying out the airtight noinvasive ventilation therapy of face shield then.We study through clinical groping for many years, develop a kind of novel practical face shield, can address this problem.
Summary of the invention
The objective of the invention is to overcome the shortcoming of above-mentioned prior art, provide a kind of simple in structure, easy to use, can annotate the food end to the stomach tube of inserting earlier and move the face shield outside to, avoid noinvasive when ventilation face shield the stomach tube place gas leakage and to the compressing of face, also avoid to reducing gas leakage, alleviating a kind of airtight novel face shield of facial compressing.
The present invention is achieved by the following technical solutions:
A kind of airtight novel face shield, include cover body, the lower edge of cover body is equipped with gasket, the last end face place of cover body is provided with connection tube, the connection tube place is set with and is linked with circle, cover body is provided with through hole, the through hole is provided with seal cover, the part of described seal cover and the outward flange of through hole are fixed together, the lower limb of another part is provided with the U-shaped projection, be provided with the U-shaped groove with the cover body of U-shaped raised position corresponding section, be provided with sealing ring in the U-shaped groove, described U-shaped projection places when closed in the sealing ring in the U-shaped groove, is provided with the lug that is connected as a single entity with it at the front end of seal cover, on the cover body with fixed handle on the fixing hole corresponding section be provided with screw rod, fixing hole is sleeved on the screw rod and by nut seal cover is compressed when closed; Be positioned at seal cover above be provided with the nasal feeding pore, nasal feeding pore place is provided with retainer ring.
What described seal cover adopted is silica gel material.
What described pipe ring adopted is hard material.
Described fixed handle is provided with gap, and an end of this gap communicates with the nasal feeding pore, is positioned at opening position and is provided with the gland that matches with gap.
Advantage of the present invention is: the present invention opens a circular side mouth on the cover body top of face shield, with the fixing semicircle that covers of resilient silica gel sealing lid, movable semicircle seal cover is provided with a hard retainer ring, be nasal feeding tube bearing in the middle of the retainer ring, open semicircle silica gel sealing lid, can annotate the food end to the stomach tube of inserting earlier and move the face shield outside to, the gas leakage at the stomach tube place of face shield and to the compressing of face when avoiding the noinvasive ventilation.Also avoid to reducing gas leakage, alleviating the situation that stomach tube use noinvasive ventilation therapy is extracted in facial compressing.Namely actively give emergency treatment to a patient, reduce medical worker's workload again.

The specific embodiment
Embodiment: airtight novel face shield as shown in the figure, include cover body 1, the lower edge of cover body 1 is equipped with gasket 2, the last end face place of cover body 1 is provided with connection tube 3, connection tube 3 places are set with and are linked with circle 4, cover body 1 is provided with through hole 12, through hole 12 places are provided with seal cover 9, what described seal cover 9 adopted is silica gel material, the part of sealing lid 9 and the outward flange of through hole 12 are fixed together, it is long-pending that the outward flange that seal cover 9 parts are fixed on through hole 12 can reduce whole silica gel capping, the lower limb of another part of seal cover 9 is provided with U-shaped projection 13, be provided with U-shaped groove 7 with the cover body 1 of corresponding section, U-shaped projection 13 position, be provided with sealing ring 8 in the U-shaped groove 7, described U-shaped projection 13 places when closed in the sealing ring 8 in the U-shaped groove 7, is provided with the fixed handle 6 that is connected as a single entity with it at the front end of seal cover 9, its objective is to be easy to open silica gel sealing lid 9 and fixing silica gel lid.On the cover body 1 with fixed handle 6 on fixing hole 14 corresponding sections be provided with screw rod 15, fixing hole 14 is sleeved on the screw rod 15 and by nut 5 seal cover 9 is compressed when closed; Be positioned at seal cover 9 above be provided with nasal feeding pore 10, nasal feeding pore 10 places are provided with retainer ring 11.What described pipe ring 11 adopted is hard material.Also be provided with gap 16 on the described fixed handle 6, an end of this gap 16 communicates with nasal feeding pore 10, is positioned at gap 16 places and is provided with the gland 17 that matches with gap 16, and gland 17 is to seal gap 16, prevents from gap 16 gas leakage.
Using method: open the silica gel sealing lid 9 on the cover body 1, pull out stomach tube from here and annotate the food end, flatten stomach tube, make it move to nasal feeding pore 10 from the gap 16 on the fixed handle 6, recovering its original shape at nasal feeding pore 10 place's stomach tubes can be with nasal feeding pore 10 stretching rear encloseds herein.Compress seal cover 9 and fixed handle 6 then, because the lower limb of seal cover 9 is provided with U-shaped projection 13, in sealing ring 8 in 13 U-shaped grooves of U-shaped projection 7, by nut 5 fixed handle 6 is compressed, cover gland 17, can make seal cover 9 sealings.Connect face shield and respirator again, can carry out effective noinvasive ventilation therapy.
