Description

Technical Field

[0001] The utility model relates to a medical appliance, in particular to a breathing machine pipeline fixing device. Background Art

[0002] Ventilators are commonly used equipment for rescuing critically ill patients. They maintain the patient's airway patency, improve ventilation and oxygenation, and prevent hypoxia through mechanical ventilation. However, patients with endotracheal intubation or tracheotomy who use mechanical ventilation for more than 48 hours are prone to ventilator-associated pneumonia.

[0003] The main cause of ventilator-associated pneumonia is that the condensed water in the respiratory duct is not dumped in time, and the reasons for its occurrence are as follows: 1. During the use of the ventilator, the ventilator duct will be fixed using the machine's special duct bracket, but the duct is long, and the excess tracheal duct part is lower than the standard specification position; the water in the condensed water cup spreads into the duct due to its tilted position, which can easily cause ventilator-associated pneumonia. 2. When the ventilator is in use, some of the ducts are lower than the standard position. When the patient has a lot of sputum, it is easy to discharge into the respiratory duct, contaminating the respiratory duct and increasing the reproduction of bacteria, causing the patient to develop respiratory-related diseases. 3. The tilt of the condensed water cup causes condensed water to flow into the respiratory duct, which causes water to block the respiratory duct, causing the patient to suffocate due to insufficient oxygen supply, and in severe cases, endangering the patient's life.

[0035] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0038] A side of the arc-shaped plate 2 away from the magnetic plate 1 is provided with a plurality of receiving grooves 11 in sequence along the length direction, and one end of a first telescopic rod 3 is hinged on the inner side wall of each of the receiving grooves 11, and the other end of the first telescopic rod 3 is provided with an external clamp 4 for clamping the ventilator pipe.

[0039] The beneficial effects of this embodiment are: the outer clamp 4 clamps the ventilator pipe, and the position and angle are adjusted by the first telescopic rod 3 to place the pipe in a suitable position, thereby preventing condensed water or sputum from flowing into the pipe and ensuring the safety of the patient; the device can be adsorbed on the ventilator body by the magnetic plate 1, and can also be clamped at any position by the clamp, which is more flexible to use and convenient to adjust.

[0040] Specifically, the magnetic plate 1 is a straight plate and has magnetism, which is convenient for adsorption on the ventilator body. The magnetic plate 1 and the arc plate 2 are hinged to form a spring clip, which is convenient for clamping and fixing at any position; when the device is not in use, the first telescopic rod 3 can be swung and stored in the storage slot 11;

[0041] Taking the axis of the horizontal axis 13 as a reference, one side of the horizontal axis 13 is a clamping part, and the other side is a gripping part. The gripping part is used for the staff to pinch open the clamping plate. A first torsion spring is sleeved on the horizontal axis 13. The first torsion spring drives the clamping parts of the magnetic plate 1 and the arc plate 2 to keep in a closed state.

[0042] When the ventilator pipeline is lower than the standard specification position, the water in the condensation cup and the patient's sputum may flow into the ventilator pipeline, breeding bacteria and causing ventilator-associated pneumonia;

[0043] After the device is fixed at any position, the first telescopic rod 3 is swung to adjust the height and position of the outer clamp 4, and the ventilator pipe is clamped on the outer clamp 4 to achieve proper fixation of the ventilator pipe;

[0044] In this solution, a damping ring may be provided at the hinge between the first telescopic rod 3 and the arc-shaped plate 2 to prevent the first telescopic rod 3 from shaking randomly during use.

[0045] Example 2

[0046] like Figure 1 to Figure 2 As shown, preferably, on the basis of Example 1, a driving component is further provided in the storage groove 11 and corresponds one-to-one with the first telescopic rod 3 to push the first telescopic rod 3 to swing around the hinge point, and one end of the driving component is hinged to the inner wall of the storage groove 11, and the other end is hinged to the outer wall of the first telescopic rod 3.

The rack box 5 is located just in front of the swinging direction of the first telescopic rod 3. The rack box 5 and the first telescopic rod 3 are both hinged on the inner wall of the storage groove 11 and the rotation axes at the hinge are parallel to each other. The rotating power source 8 drives the gear 9 to rotate forward or reverse, the gear 9 drives the rack 7 to extend or retract, and the other end of the rack 7 drives the first telescopic rod 3 to swing and adjust the angle; when adjusted to the appropriate position, the rotating power source 8 stops rotating, and the gear 9 stops to prevent the rack 7 from sliding by itself.

[0056] On the basis of this embodiment, damping can be set in the slide groove 6 to increase the sliding friction of the rack 7 to prevent sliding when the rack 7 needs to be stationary; a power-off self-locking function can also be set on the rotating power source 8.
