Description

Noninvasive vent pipe

Technical Field

The utility model relates to the technical field of medical appliances, in particular to a noninvasive vent pipe.

Background

Respiratory disorders can be caused clinically by a variety of etiologies. In adults, cardiovascular and cerebrovascular diseases, respiratory diseases and the like are common, and in children, drowning, electric shock, poisoning and the like are common. The illness state of the breathing disorder is critical, and the patient dies if the patient is not in emergency rescue. The main rescue links comprise the establishment of an emergency temporary artificial airway and the ventilation support of an artificial or machine. Current common rescue modes include noninvasive mouth-to-mouth artificial respiration and mask ventilation, and invasive endotracheal intubation and tracheal dissection. Regarding the establishment and maintenance of temporary airways, the noninvasive operation method is simple, is applicable to various scenes, is easy to popularize to society, has uncertain curative effect, and needs invasive operation to establish more stable airways for serious patients in the later stage; while invasive procedures require complex expertise and equipment, they are difficult to access at first time, except for a very small number of advanced medical facilities.

Chinese patent document CN202121873389.2 discloses a portable full-automatic micro respirator, which comprises a pipeline unit, a control unit and an air supply unit. When the spontaneous breathing of the patient is lost, a pipeline unit of the device can be used for being placed in the mouth of the patient to establish a temporary airway, and a mode control unit with a built-in working program starts and instructs an electric air supply unit taking an air pump as a core to complete the breathing support work of the patient. The device is an innovative scheme of first-line first-aid. It is only conceptually illustrative of the pipeline units and the specific design and parameters are not well defined, which may adversely affect the resulting rescue effect.

In view of the foregoing, there is a need for a new medical ventilation tube for establishing a temporary airway in emergency. The novel ventilation device has the advantages of non-invasiveness, good ventilation effect, easiness in operation, convenience in popularization, low cost, easiness in acquisition and the like. And can be matched with a novel portable full-automatic micro respirator for use, thereby comprehensively improving the success efficiency of rescuing patients with respiratory disorder.

Disclosure of Invention

The utility model aims to provide a novel medical vent pipe which is used for establishing a temporary airway in emergency treatment. The novel ventilation device has the advantages of non-invasiveness, good ventilation effect, easiness in operation, convenience in popularization, low cost, easiness in acquisition and the like.

The mouth pad structure can be roughly seen as a double-layer cylinder-like sleeve structure of a mouth pad inner sleeve and a mouth pad outer sleeve, and the middle is connected by a bracket.

The inner wall of the inner sleeve of the mouth pad is tightly attached to the tube body. The two have larger damping so as to achieve the effect that the two can move under the condition of stress application, but cannot slide easily at ordinary times.

The external sleeve of the mouth pad is an elliptic cylinder, and is provided with a baffle, a tooth groove and a tongue pad. The tongue pad is positioned at the arc inner side of the pipe body;

the outer sleeve of the mouth pad extends out of a baffle plate in the up-down direction at the outer wall of the tail end of the tube body. The function of the baffles is that when the mouth pad structure is placed in the mouth of a patient, the two baffles will abut against the outer sides of the teeth or lips, preventing the whole mouth pad from sliding into the mouth.

The external tube of mouth pad outer wall be equipped with the alveolus, the alveolus be annular arch, mouth pad outer tube surface sets up three archs and regard as the alveolus, the effect lies in, when mouth pad structure is put into the patient mouth, the upper and lower tooth of patient will be between the scale, is convenient for restrict mouth pad and produces the removal.

The mouth pad outer sleeve faces the head end of the pipe body and only faces the arc inner half part of the pipe body, and a sheet-shaped structure is continuously stretched out to the head end of the pipe body to form a tongue pad. The tongue pad has the function of being convenient for pressing the tongue of a patient when the mouth pad is placed in the mouth of the patient, and preventing the falling back thereof from blocking the airway.

The inside of the mouth pad and the outside sleeve are supported by the bracket to form a hollow structure. The important function of this structure is that during the expiration phase of the patient's breath, the gas is expelled from the body through this hollow structure.

The noninvasive vent pipe of the utility model can independently bear conventional disinfection and sterilization.

By adopting the structure, the utility model has the following beneficial effects:
