Abstract

The utility model relates to a component for a respiration protecting device, particularly a tooth pad which is used for holding or supporting a tracheal catheter. A pad body is a double-pad body, wherein, the side of one pad is fixedly connected with the side of the other pad by a connecting piece; the other side of one pad is movably connected with the other side of the other pad by a lock tongue and a latch; a catheter fixing slot is arranged between the pads, and liquid is discharged by a cannula inserted in a liquid discharging hole on the pads. Therefore, the utility model has the advantages that the fixing operation for tracheal catheters is simple; tracheal catheters can not easily slip; the collected liquid or the collected phlegm in the mouth cavities can be discharged in time. The utility model is suitable for being used in the operations with general anesthesia in hospitals.

Description

Bite-block

This utility model relates to the member of respiratory protection equipment, especially a kind ofly is used to keep or the bite-block of rest endotracheal tube.

As everyone knows, patient needs the endotracheal tube outfan is inserted in the trachea when doing the general anesthesia operation, and the endotracheal tube input is connected with respirator, to support patient respiration.In order to prevent that patient stings flat endotracheal tube and in time handles hydrops in the patient's mouth or long-pending expectorant and adopted bite-block.Present employed bite-block is the monomer bite-block, comprises piped pad, is positioned at the outage of locating in the pad axle center, the conduit holddown groove that is positioned at the pad both sides.Wherein the two ends of pad are respectively rank and sting end and stiff end, and the centre is provided with and can prevents the long limiting plate that enters the oral cavity of bite-block.During use, endotracheal tube is positioned in the conduit holddown groove of pad one side, stiff end at pad is fastened with adhesive tape, the rank of pad is stung end insert in the oral cavity together with fixed endotracheal tube outfan with it, and insert the suction pipe discharge opeing by the outage at place, pad axle center.The conduit holddown groove of the bite-block of this structure is narrow shallow, and fixedly contact area is little with endotracheal tube, exist to be difficult for fixed shortcoming, and after fixation adhesive tape was moistening, conduit easily produces slip, causes operation dangerous; In addition, the outage on the pad is positioned at endotracheal tube one side, the hydrops of endotracheal tube opposite side or long-pending expectorant is existed can't get rid of clean shortcoming.

The purpose of this utility model is to provide a kind of endotracheal tube hydrops or long-pending expectorant fixing easily and that can't produce in slip, the patient's mouth can in time get rid of clean bite-block.

For achieving the above object, this utility model comprises pad, outage, conduit holddown groove, limiting plate etc., described pad is made up of two pads, be respectively equipped with outage on two pads, one side of two pads is fixedly connected by brace, opposite side is flexibly connected by dead bolt provided thereon, snap close, is provided with the holddown groove that can contain endotracheal tube between two pads.

Pad of the present utility model is two pads, side at two pads is fixedly connected by brace, opposite side is flexibly connected by dead bolt, snap close, be provided with the conduit holddown groove between the pad, and by the outage intubate discharge opeing on two pads, so the utlity model has the endotracheal tube fixing operation easy, be difficult for to produce slide, can in time get rid of the hydrops in the oral cavity or the advantage of long-pending expectorant.

Description of drawings:

Accompanying drawing is a kind of structural representation of the present utility model, also is the sketch map of a kind of embodiment.

Fig. 1 is a front view of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is the left view of Fig. 1;

Fig. 4 is the A-A cutaway view of Fig. 2.

Below in conjunction with the drawings and specific embodiments this utility model is described further.

As Fig. 1, Fig. 2, shown in Figure 3, pad 1 adopts polythene material to make, it is made up of two monomer pads, on each pad, offer outage 2, in order to increase the contact range of inserting the discharge opeing suction pipe in the outage 2, sting end in the rank of pad 1 and offer imbibition breach 3, on two pads, be respectively equipped with and prevent that pad rank stings the long limiting plate 4 that enters the oral cavity of end; As Fig. 1, shown in Figure 4, one side of two pads is fixedly connected by brace 5, brace 5 can adopt polythene material, once molding formed with pad 1, limiting plate 4, at the opposite side of two pads, collude lock mutually and flexibly connect by being located at the dead bolt 6 on one of them pad and being located at plough groove type snap close 7 on another pad.Offer the holddown groove 8 that can contain endotracheal tube between two pads, holddown groove 8 adopts interference fit with endotracheal tube, and the endotracheal tube that is sandwiched in admittedly in the holddown groove 8 is not slided.

During use, break two pads into two with one's hands, endotracheal tube is loaded on holddown groove 8, utilize dead bolt 6, snap close 7 on two pads that the locking of two pads is connected, endotracheal tube is firmly secured in the holddown groove 8, the rank of pad 1 is stung end insert in patient's the oral cavity, start the respirator support patient respiration that is connected with endotracheal tube together with fixed endotracheal tube with it; When having hydrops or long-pending expectorant in the patient's mouth, insert the discharge opeing suction pipe by the outage on two pads 2, can get rid of hydrops in the patient's mouth or long-pending expectorant clean easily.

Claims

1, a kind of bite-block, form by pad, outage, conduit holddown groove etc., the two ends of pad are respectively rank and sting end and stiff end, the centre is provided with and can prevents that bite-block rank stings the long limiting plate that enters the oral cavity of end, it is characterized in that: described pad is made up of two pads, is respectively equipped with outage on two pads, and a side of two pads is fixedly connected by brace, opposite side is flexibly connected by dead bolt provided thereon, snap close, is provided with the holddown groove that can contain endotracheal tube between two pads.
