Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a cannula fixer. Background Art

[0002] The duty of an anesthesiologist is to ensure that the patient can complete the operation together with the surgeon under the premise of painlessness and safety. Therefore, anesthesia is an indispensable part of the operation. When anesthetists perform anesthesia, they need to insert the cannula used for anesthesia into the patient's mouth and enter the breathing duct through the mouth. During the operation, the tube needs to be fixed in the patient's mouth at all times. Therefore, a cannula fixator is particularly needed.

[0003] At present, when fixing the cannula holder, tape is often used to adhere to the patient's facial skin. This fixing method will not only become loose with the shaking of the patient's mouth, sweating, etc., affecting the fixing effect, but will also cause damage to the patient's facial skin. Alternatively, it can be fixed with a strap. When this method is used, the strap will bypass the back of the head. When the back of the patient's head contacts the pillow, there will be a certain degree of unevenness. Once the patient stays in bed for a long time, the back of the patient's head and the protruding strap will easily feel uncomfortable. If the patient's head is uncomfortable, it will twist, causing the cannula holder to become loose and affecting the fixing effect. Therefore, the present application proposes a cannula holder to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the embodiments:

[0022] Example 1

[0023] like Figure 1-4 As shown, the utility model provides a cannula holder, including a fixing plate 1, which is made of soft material and in direct contact with the patient's mouth to ensure comfort in use. A through hole 2 is opened on the outer surface of the fixing plate 1, and a tooth plate 17 is installed on the inner side of the fixing plate 1. A mounting sleeve 3 is installed on the outer surface of the fixing plate 1 and is located outside the through hole 2. A clamping mechanism is installed on the inner side of the mounting sleeve 3. Fixing mechanisms are installed on both sides of the fixing plate 1. Cannulas of different sizes pass through the through hole 2 through the mounting sleeve 3. The position of the inlet of the cannula is fixed by the clamping mechanism, and the fixing plate 1 is installed on the patient's mouth by the fixing mechanism. The setting of the fixing mechanism can prevent a layer of strap from protruding from the back of the patient's head, causing discomfort at the abutment point of the head, thereby preventing the patient from twisting due to discomfort in the head, resulting in loosening of the cannula holder and affecting the fixing effect.

[0024] Furthermore, the fixing mechanism includes a fixed shaft 9 installed on both sides of the fixing plate 1, and a breathable strap 10 is movably connected to the outer surface of the fixed shaft 9, one end of the breathable strap 10 is connected to a strap sleeve 11, and a fixed shaft 2 12 is movably connected to the inner wall of the strap sleeve 11, one side of the fixed shaft 2 12 is connected to a soft baffle 13, and one side of the soft baffle 13 is connected to a covering bottom strap 14. The covering bottom strap 14 can cover the back of the patient's head. At the same time, the breathable strap 10 bypasses the fixed shaft 9 and is fixed on both sides of the patient's face to avoid the strap on the patient's head to form a bulge, causing uncomfortable wearing. The breathable strap 10 and the covering bottom strap 14 are both made of breathable materials to avoid the problem of sweating while wearing.

[0025] Furthermore, the other end of the breathable strap 10 passes through the fixed axis 9 and is folded and connected by Velcro. Velcro is installed on the adjacent side of the breathable strap 10 that passes around the fixed axis 9. The length of the breathable strap 10 passing around the fixed axis 9 can be adjusted to adapt to the use of different patients.

[0026] Furthermore, protective cotton sheets 15 are installed on the inner sides of the soft baffle strip 13 and the covering bottom belt 14. The protective cotton sheets 15 are made of soft and breathable material to ensure the comfort of the patient's head during use.

[0027] Furthermore, the clamping mechanism includes a threaded rod 4 threadedly connected to the inner wall of the mounting sleeve 3, one end of the threaded rod 4 extends to the interior of the mounting sleeve 3 and is connected to a clamping plate 5, and one end of the threaded rod 4 located on the outside of the mounting sleeve 3 is connected to an adjusting head 8. After the cannulas of different sizes are inserted through the mounting sleeve 3 and the through hole 2, the adjusting head 8 is rotated so that the threaded rod 4 can push the clamping plate 5 to move toward the inside of the mounting sleeve 3 until it abuts against the outside of the cannula, thereby achieving the purpose of fixing the position of the cannula.

[0028] Furthermore, a soft protective plate 6 is installed on the inner side of the splint 5, and a plurality of friction strips 7 are installed on one side of the soft protective plate 6. Through the action of the soft protective plate 6 and the friction strips 7, the friction force between the splint and the cannula is increased, and while the clamping stability is improved, a certain protection effect is formed for the cannula, thereby avoiding the problem of damage to the outer surface of the cannula during the clamping and loosening process.

[0029] Furthermore, an auxiliary fixing plate 16 is installed on the inner side of the fixing plate 1 near the edge of the through hole 2, and multiple auxiliary fixing plates 16 are installed to converge toward the axis of the through hole 2, so that after the cannula enters the patient's mouth through the auxiliary fixing plate 16, the auxiliary fixing plate 16 is squeezed to cause it to undergo elastic deformation, and a certain limiting effect is formed on the cannula inside the patient's mouth, thereby minimizing the possible shaking amplitude of the cannula.

[0030] The working principle of the cannula holder is described in detail below.

[0031] like Figure 1-4 As shown, cannulas of different sizes pass through the through hole 2 via the mounting sleeve 3, and the adjusting head 8 is rotated so that the threaded rod 4 can push the clamping plate 5 to move toward the inside of the mounting sleeve 3 until it abuts against the outside of the cannula. The soft protective plate 6 and the friction strip 7 increase the friction between the cannula and the clamping stability, while providing a certain degree of protection for the cannula. Then, the back of the patient's head is wrapped with the covering bottom belt 14 and the protective cotton sheet 15, and the breathable strap 10 is passed around the fixed axis 9. Velcro is installed on the adjacent side of the breathable strap 10 passing around the fixed axis 9, and the strap is fixed by the adhesive effect of the Velcro. The length of the breathable strap 10 passing around the fixed axis 9 can be adapted to the use of different patients and fixed on both sides of the patient's face.
