Description

A cover is ventilated to plasticity U-shaped for operation of ophthalmology office anesthesia

Technical Field

The utility model relates to the field of medical equipment, in particular to a plasticity U-shaped ventilation hood for ophthalmologic local anesthesia operation.

Background

In the process of performing the ophthalmic surgery, according to the aseptic requirement of the ophthalmic surgery, at least four layers of aseptic surgical towels need to be paved on the face of a patient, because the aseptic towels have good tightness and poor air permeability, most patients in the ophthalmic surgery are old people and commonly suffer from heart and lung diseases, the lung ventilation volume is relatively insufficient, when the aseptic towels directly cover the mouth and nose parts of the patients, the patients are difficult to breathe normally due to the lack of facial support, the patients often feel suffocated and lack of ventilation, particularly for long-time surgeries such as posterior segment surgeries of eyes and the like, the air circulation under the airtight towels is less, carbon dioxide accumulates under the surgical towels, the patients repeatedly inhale too much carbon dioxide to generate hypercapnia and hypoxia symptoms, the dysphoria is more easily generated, the subjective feeling of the patients cannot be changed even if oxygen is inhaled, the patients are difficult to cooperate with the surgeries, the surgeries are often required to be suspended, and the positions of the aseptic, even if the operation needs to be cancelled, the process and the safety of the operation are influenced, medical hidden dangers exist, and the operation experience of a patient is poor; in order to solve the problem of unsmooth ventilation caused by the covering of the operation towel on the head and face of a patient subjected to ophthalmologic local anesthesia operation, various ophthalmologic operation supports, trays and masks are mostly adopted to support the towel on the mouth and nose to form a certain breathing space, so that the patient can breathe smoothly in the operation process, and the operation is better matched, but the support ventilation device is too close to the mouth and nose to be convenient for placing an operation microscope, and the operation is influenced; too far from the mouth and nose can affect the support of the sterile towel and not achieve the effect of improving the ventilation of the patient. The manufacturing and the assembly and the disassembly of part of the bracket or the face mask are complex, the materials are inconvenient to obtain, the ventilation performance is poor, the price is high, the conventional use in all levels of hospitals is not suitable, and the clinical practicability is poor; the contours of the face vary from patient to patient, making the use of conventional ventilation masks uncomfortable and prone to dislodgement and dislodgement. Therefore, a simple and practical device for improving the ventilation comfort of the ophthalmic local anesthesia operation is yet to be designed and developed.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a plasticity U-shaped cover of ventilating for operation of ophthalmology department anesthesia to solve one or more technical problem that exist among the prior art, provide a profitable selection or create the condition at least.

The technical scheme adopted for solving the technical problems is as follows:

a plastic U-shaped ventilation hood for ophthalmologic local anesthesia operation comprises a top frame, a base and a connecting rod, wherein the top frame is horizontally arranged, the base is horizontally arranged right below the top frame, and the base is of a U-shaped structure capable of deforming plastically; the connecting rod is provided with at least one, at least one the connecting rod is between vertical slope setting base and the roof-rack, the upper end and the roof-rack of connecting rod are connected, the lower extreme and the base of connecting rod are connected.

The utility model has the advantages that: when doing ophthalmic surgery to the patient, the handle the utility model discloses a plasticity U-shaped cover of ventilating is at patient's oral area, specifically: the base of the U-shaped structure is sleeved at the edge of the oral cavity of the patient, and the opening of the base of the U-shaped structure faces the nose of the patient. Then cover the operation hole piece of cloth on the roof-rack, under the connecting rod support between base and roof-rack, make it makeing somebody a mere figurehead between patient's oral area and nasal part and the operation hole piece of cloth, avoid patient's mouth, nose direct contact to hole piece of cloth, prevent that the patient from feeling suffocated, ventilative not smooth, even breathe the difficulty, the patient has effectively been alleviated because of breathing the oxygen deficiency that is smooth to lead to, but the base of plastic deformation can be according to patient's facial profile simultaneously, adjust the open-ended direction of this U-shaped structure and the type, adjust to the most comfortable state of patient, make the base can hug closely on patient's oral area, the comfort level of ventilating in the improvement patient art, avoid appearing shifting and the phenomenon that drops, this ventilation cover simple structure, do not have too many spare parts, and convenient to use, only need the suit patient on the.

As a further improvement of the above technical solution, in a plan view projection, an outer contour of the base is larger than an outer contour of the top frame.

This can lower the center of gravity of the ventilation hood, and can expand the supporting range of the base, and can improve the stability of the ventilation hood support.

As a further improvement of the technical scheme, the top frame is of a circular ring structure, and the axis of the circular ring structure is vertically extended.

The top frame with the circular ring structure can reduce the material of the ventilation hood, and the top frame can support the surgical towel more stably, so that the surgical towel is supported in the mouth of a patient to form an umbrella-shaped structure, and gaps between the mouth and the nose of the patient and the surgical towel are enlarged.

As a further improvement of the technical scheme, the base comprises an inner pipe and an outer pipe, the inner pipe is sleeved in the outer pipe to form the U-shaped structure capable of deforming plastically, and the outer side wall of the outer pipe is connected with the lower end of the connecting rod.

Wherein the inner tube plays the fixed effect of plastic deformation, because the outer tube is located to the inner tube cover, the inner tube adopts plastic material to make, the outer tube is soft plastic tubing, at this moment outer tube and patient's face contact, and then makes the inner tube can adopt different plastic deformation material, avoids plastic deformation material direct and patient's face contact and causes contusion or allergy to the outer tube is soft plastic tubing, further improves patient's comfort level.

As a further improvement of the technical scheme, the top frame, the connecting rod and the outer pipe are integrally formed by injection molding. This can improve the holistic structural strength of ventilation cover, avoids appearing the phenomenon of scattering the frame.

As a further improvement of the above technical solution, two pairs of the connecting rods are provided, the opening of the U-shaped structure faces the front side, the two pairs of the connecting rods are symmetrically arranged on the left and right sides of the opening of the U-shaped structure, and each pair of the connecting rods are arranged at intervals. Two pairs of connecting rods can further reduce the material of the cover of ventilating under the prerequisite of playing the support to reduce cost also makes the cover of ventilating form the passageway in the front and back direction simultaneously, makes patient's breathing more smooth and easy.

As a further improvement of the technical scheme, the two connecting rods of each pair are arranged at an included angle. This can improve the firmness of the connection between the top frame and the base and the stability of the support.

As the further improvement of the above technical scheme, the utility model discloses still including hanging the area, the quantity of hanging the area is provided with two, two it articulates in two pairs to hang the area between the connecting rod. When the adjustable ear-hook is used, the two hanging belts are hung on the auricle of a patient respectively, the ventilation cover can be fixed, and the two hanging belts are provided with adjusting buckles capable of adjusting the lengths of the hanging belts respectively.
