Description

Technical Field

[0001] The utility model relates to the technical field of mouth openers, in particular to a visual intubation type mouth opener. Background Art

[0002] A mouth opener is a device used to hold the mouth open when breathing is difficult or when gastric lavage is required for unconsciousness. In medicine, based on its ability to keep the mouth open, mouth openers have many practical uses, such as keeping the mouth open of a comatose patient to assist with mouth breathing or oral care. Mouth openers can also be used on uncooperative individuals, such as young infants or animals, to deliver medication through the esophagus or perform oral treatment procedures.

[0003] Metal mouth openers are used to hold the mouth open in emergency situations and are generally made of medical stainless steel. Mouth openers are divided into: forceps type, T-type, horizontal type, square type, anesthesia type (left and right) and other specifications. The most famous in the dental department is David's half-mouth opener, which contains 5 tongue depressors with a fixed tongue depressor button on the frame. The five tongue depressors have a cannula interface, which allows the cannula to be safely inserted from the bottom of the tongue depressor; the half-mouth mouth opener frame has two tooth hooks and a tongue depressor fixing button. Three newly designed tongue depressors have cannula slots, which allow the cannula to be safely inserted from the bottom of the tongue depressor. The full-mouth mouth opener kit frame has two tooth hooks and tooth hook fixing springs, a small retractor on each side, and a tongue depressor fixing button. Three tongue depressors have cannula slots, which allow the cannula to be safely inserted from the bottom of the tongue depressor.

[0004] The patent document with announcement number CN209733945U discloses a visual laryngoscope equipped with a movable guide blade. Under the driving action of external force, the movable guide blade can be rotated and switched between an open position and a closed position to open or close the front end opening of the laryngoscope blade, which solves the technical problems of the large front end size of the existing visual laryngoscope, such as the difficulty in insertion and removal and the risk of throat compression. It can not only achieve a high success rate and easy operability of intubation and removal assisted by a laryngoscope with an internal guide blade, but also greatly reduce the risk of damage to the patient's throat caused by traditional fixed guide blade laryngoscopes, thereby improving the patient's treatment effect.

[0005] However, research has found that existing video laryngoscopes equipped with movable blades have certain disadvantages when used:

[0006] The video laryngoscope as a whole avoids damage to the patient's throat by rotating the movable guide blade between an open position and a closed position. However, in actual application, the video laryngoscope is the same as a traditional laryngoscope. When the patient is in a coma and his teeth are clenched, it is difficult to open his mouth. When inserting the tongue-depressing part of the video laryngoscope, there is a large obstruction, which is not conducive to avoiding intubation obstructions during emergency rescue of unconscious patients.

DETAILED DESCRIPTION

[0033] Example 1:

[0034] A visual intubation type opener, such as Figure 1-Figure 3 、 Figures 5 to 7 As shown, it includes an opener body 6, a tongue depressing structure 7 provided on one side of the opener body 6, and a laryngoscope handle 2 located between the opener body 6 and one end of the tongue depressing structure 7. One end of the laryngoscope handle 2 is provided with a visual laryngoscope display 1, and the other end of the laryngoscope handle 2 is assembled and connected with an extension handle 3. The other ends of the opener body 6 and the tongue depressing structure 7 are both extended into the mouth;

[0035] like Figure 1 、 Figure 3 and Figure 6 As shown, the opener body 6 includes an opener base 604, one end of the opener base 604 is hingedly connected to an L-shaped support arm A601, the other end of the opener base 604 is hingedly connected to an L-shaped support arm B602, the top of the L-shaped support arm B602 near one end of the opener base 604 is processed with a threading elbow 609, the middle part of the opener base 604 is threadedly connected to a threaded rod 603, and one end of the threaded rod 603 is processed with a control handle 608;

[0036] The L-shaped support arm 602 and the L-shaped support arm A601 are respectively supported on the teeth in the mouth by the L-shaped support arm A601 and the L-shaped support arm B602. The L-shaped support arm A601 is connected to the mouth opening device by the L-shaped support arm B602 and the L-shaped support arm A601.

[0037] At the same time, by passing the laryngoscope probe 12 for obtaining images of the patient's body through the threading elbow 609 and between the L-shaped support arm A601 and the L-shaped support arm B602, one end of the laryngoscope probe 12 can be inserted into the patient's throat to obtain images of the patient's throat, which is easy to operate;

[0038] Secondly, in order to prevent the laryngoscope probe 12 from being scattered when passing between the L-shaped support arm A601 and the L-shaped support arm B602, it is not easy to enter the patient's mouth. Figure 5 and Figure 6 As shown, a semicircular notch 13 is formed on the surface of the L-shaped support arm A601 near the L-shaped support arm B602, and a threading tube 607 is processed on the surface of the L-shaped support arm B602 near the L-shaped support arm A601. By integrally molding half of the threading tube 607 into the interior of the L-shaped support arm B602 and making the threading tube 607 fit into the interior of the semicircular notch 13, when the L-shaped support arm A601 and the L-shaped support arm B602 are close to each other, a gap can be avoided between the two, ensuring that one end of the L-shaped support arm A601 and the L-shaped support arm B602 can extend into the interior of the small space and expand the opening;

[0039] At the same time, by moving the laryngoscope probe 12 through the inside of the threading elbow 609 to the inside of the threading tube 607, a guide can be provided for the threading work of the laryngoscope probe 12, so that one end of the laryngoscope probe 12 can be accurately inserted into the patient's oral cavity through the inner side of the opening of the mouth opener body 6;

[0040] In some examples, such as Figure 2 、 Figure 6 and Figure 7 As shown, two screw heads 605 are provided between the opener base 604 and the L-shaped support arm B602, and between the opener base 604 and the L-shaped support arm A601, and a spring 610 is processed between the two screw heads 605;

[0041] Among them, by setting the thread rotation direction of the two screw heads 605 to the same state, a conventional bolt can be simulated on one side of the opener base 604, and one screw head 605 between the opener base 604 and the L-shaped support arm B602 and the opener base 604 and the L-shaped support arm A601 is threadedly connected to the inside of the opener base 604, another screw head 605 between the opener base 604 and the L-shaped support arm B602 is threadedly connected to the inside of the L-shaped support arm B602, and another screw head 605 between the opener base 604 and the L-shaped support arm A601 is threadedly connected to the inside of the L-shaped support arm A601;

[0042] At the same time, with the help of two springs 610, which are pulled between one end of the opener base 604 and the L-shaped support arm B602, and the other end of the opener base 604 and the L-shaped support arm A601, it is possible to prevent the L-shaped support arm A601 or the L-shaped support arm B602 from rotating and hanging down around the hinge point with the opener base 604 in a natural state, thereby affecting actual use;

[0043] Secondly, in order to prevent one end of the junction of the L-shaped support arm A601 and the L-shaped support arm B602 (i.e., the right-angled corner of the L-shaped support arm A601 and the L-shaped support arm B602) from being pushed by the screw head 605, so that the L-shaped support arm A601 and the L-shaped support arm B602 rotate around the hinge point with the opener base 604, the spring 610 interferes with the opener base 604 and the L-shaped support arm A601 (or the L-shaped support arm B602), and a storage space is provided for the spring 610, so that the right-angled sides of the L-shaped support arm B602 and the L-shaped support arm A601 are in contact with each other in a natural state, as shown in FIG. Figure 7 As shown, the interior of the L-shaped support arm B602 and the L-shaped support arm A601 near one end of the opener base 604, and the interior of the two ends of the opener base 604 located on one side of the L-shaped support arm A601 and the L-shaped support arm B602 are all processed with a conical groove 11. By making the two conical grooves 11 on the opener base 604 face the conical grooves 11 on the L-shaped support arm B602 and the L-shaped support arm A601 respectively, and the area of ​​the part facing the two conical grooves 11 is the largest, the spring 610 is movably connected to the inside of the two facing conical grooves 11, which can ensure that the spring 610 can move smoothly in the opener base 604 and the L-shaped support arm A601 (or the inside of the L-shaped support arm B602).

[0044] The present invention provides a visual intubation type opener. The opener body 6 is used in combination with a visual laryngoscope display 1 having a laryngoscope handle 2 and a laryngoscope probe 12. The ends of the L-shaped support arms A601 and B602 on the opener body 6 away from the laryngoscope handle 2 are extended into the mouth, and the control handle 608 on the opener body 6 is controlled to adjust the threaded connection between the threaded rod 603 and the opener base 604. The ends of the L-shaped support arms A601 and B602 where they meet are pushed, and the L-shaped support arms A601 and B602 are rotated around the hinge points with the opener base 604, so that the distal ends of the L-shaped support arms A601 and B602 are moved away from each other, thereby opening the mouth from the teeth, without the need for medical staff to manually open the teeth.

[0045] At the same time, one end of the laryngoscope probe 12 is passed through the threading elbow 609 at the top of the L-shaped support arm B602 and into the interior of the threading tube 607. The threading tube 607 is used to guide the movement path of the L-shaped support arm B602. After one end 612 is extended from the interior of the threading tube 607, it can be extended into the throat through the mouth, so that the camera at one end of the laryngoscope probe 12 can be used to obtain the patient's throat image (the image is obtained using the well-known technology in this field) to support the corresponding treatment work.
