Description

Open type ventilation mask for ophthalmic operation

Technical Field

The utility model relates to an equipment that uses in the surgery, and especially relate to an ophthalmic surgery open face guard of ventilating who uses for the patient in the ophthalmic surgery.

Background

The present disclosure generally relates to an ophthalmic surgical open ventilation mask for use in surgery. It can deliver oxygen to the mouth and nose of a patient without affecting the normal breathing of the patient.

In various clinical operations, the ophthalmic operation has high requirement on sterility, and a sterile surgical drape is needed to cover the head, the face, the chest and the abdomen of a patient in the operation so as to prevent bacteria from polluting the operation part in the operation. In order to achieve an effective isolation effect, the common surgical drape has poor air permeability, and a patient has obvious oppression feeling. For elderly patients, especially patients with poor heart or respiratory diseases, the feeling of suffocation is particularly severe and the operation cannot be performed smoothly. The current clinical solution to this problem is to place the distal end of a long oxygen tube in the mouth and nose of the patient to deliver oxygen. The method has the advantages that oxygen can be delivered to the mouth and nose of a patient, and oxygen deficiency of the patient is reduced; the oxygen tube is thin, the oxygen tube has no effective supporting function, the patient still has obvious suffocating feeling when the operation sheet is close to the mouth and nose, and on the other hand, the air flow speed of the oxygen tube is fast, and the air flow sprayed to the mouth and nose has obvious discomfort feeling such as pruritus and the like. Therefore, there is a need in the ophthalmic clinic for an ophthalmic surgical open ventilation mask that is capable of delivering oxygen in a dispersed manner while supporting the oronasal space. The utility model provides a novel ventilation mask which can meet the requirements.

Disclosure of Invention

The present disclosure describes an ophthalmic open-ventilation mask including a mask support, an airway tube, an airflow diffuser, and a mask strap.

Various aspects can include one or more of the following features. The ventilation pipeline is a flexible hollow pipeline, can convey gases such as oxygen and the like, and is connected between the airflow disperser and the air source. The vent tube is made of flexible medical materials. The cross-section of the vent duct may be circular or other shapes, or may be different shapes in different sections. The vent tube may have a cross-sectional diameter that varies along its length. The airflow disperser is positioned on the inner surface of the mask bracket and is of a porous cavity structure, and the air inlet of the airflow disperser is connected with the ventilation pipeline. The inner side wall of the airflow disperser is provided with a plurality of airflow dispersing holes, so that high-speed airflow input by the ventilation pipeline can be uniformly and slowly released into the space of the mask bracket.

Various aspects can also include one or more of the following features. The mask support is of a three-dimensional structure with the middle part protruding forwards, the edge of the mask support is of a three-dimensional structure capable of being attached to the mouth and the nose, and one or more vent holes are formed in the side face of the mask support. The mask straps include one or more straps. The face guard frenulum passes through coupling structure and connects in face guard support both sides, and its middle part width is great, and both ends width is less. The mask belt is made of elastic or non-elastic material. The coupling structure of the mask belt and the mask bracket adopts a fastening belt or other types of coupling structures which are convenient and quick to operate.

In the using process, the tail end of the ventilation pipeline is connected with the oxygen bottle, the air flow is adjusted, the mask support is covered on the mouth and nose part of a patient, the fastening tapes at the two ends of the mask lacing are attached to the fastening tapes at the two sides of the mask support, and the mask is fixed on the mouth and nose part. When the mask is used, the oxygen is closed, the magic tapes at the two ends of the mask lacing are uncovered, and the mask is removed.

Detailed Description

The present disclosure relates to an ophthalmic surgical open ventilation mask for use in surgery. It can deliver oxygen to the mouth and nose of a patient without affecting the normal breathing of the patient.

Fig. 1, 2, 3 show an example ventilation mask 001. The ventilation mask 001 mainly comprises a mask support 002, a ventilation pipeline 003, an airflow disperser 004 and a mask tie 005. The mask support 002 has one or more mask vents 006 on the side. The mask vents 006 may be circular, oval or other suitable shapes. Two hook surface fastening tapes 007 are respectively attached to two side surfaces of the mask support 002. The edges of the mask holder 002 are attached with a soft mask skirt 008. An airflow diffuser 004 is attached to the inner surface of the mask support 002 near the top. Vent tube 003 has a tube front end 013 and a tube rear end 014. The rear end 014 of the tube can be connected to an oxygen cylinder or oxygen line (not shown).

Fig. 4 shows an example airflow disperser 004. The inner side of the air diffuser 004 has a plurality of air diffusing holes 009. Airflow connection tube 010 has a connection tube front end 011 and a connection tube rear end 012. The air connection tube 010 is attached to the air diffuser 004. The front end 011 of the connecting pipe is led into the inner cavity of the airflow disperser 004. The rear end 012 of the connection tube extends out of the mask holder 002. The connection pipe rear end 012 can be coupled with the pipe front end 013 in an interference manner.

Fig. 5 shows a mask strap 005. The mask straps 005 are made of one or more medical grade materials that are flexible. The two ends of the mask strap 005 are attached with thread surface fastening tapes 015. The thread surface fastening tapes 015 can be coupled with the hook surface fastening tapes 007 on both sides of the mask support 002.

In the use process, at first can be connected pipeline rear end 014 with oxygen cylinder or oxygen pipeline (not shown), be connected pipeline front end 013 with connecting pipe rear end 012 again, then place mask support 002 in patient's oronasal part (not shown), walk around patient's neck portion with mask frenulum 005, adjust suitable elasticity, laminate the silk face thread gluing area 015 of the both ends of mask frenulum 005 and the hook face thread gluing area 007 of the two sides of mask support 002 mutually, fixed mask support 002 adjusts the oxygen flow and begins the oxygen uptake. After use, the silk surface adhesive tape 015 is removed, and the ventilation mask 001 is taken down.
