Description

Technical Field

[0001] The utility model belongs to a neck lifting device, and particularly relates to a neck support for general anesthesia patients, which is used to lift the lower jaw of general anesthesia patients upward to facilitate the insertion of instruments such as gastroscopes. Background Technique

[0002] General anesthesia gastroscopy, also known as painless gastroscopy, is performed under the premise that the patient's echocardiogram, pulmonary function test, coagulation function, electrocardiogram and other evaluation items are normal. An anesthesiologist gives the patient intravenous injection of short-acting anesthetic drugs to make the patient fall into a sleep state within a short time, and then performs the operation of gastroscopy.

[0003] During the insertion of the endoscope, the patient generally needs to maintain a left lateral position and keep the head tilted slightly upward. The head tilting angles of different patients are not the same, which should be determined according to the positions of organs such as the esophageal orifice, hypopharynx, and piriform recess. In this way, it is not easy to damage the oral cavity, esophageal inner wall and cartilage tissue during the entry. After general anesthesia, the neck muscles of the patient are in a relaxed state, and the head cannot maintain the raised posture. Therefore, during the insertion of the endoscope, a medical staff needs to hold the patient's head with one hand and hold the mouth opener with the other hand to prevent the patient's mouth from closing. The defects of this method are as follows: 1. The medical staff is generally located behind the patient. Observing the head posture from this position is affected by the line of sight, and the head posture cannot be grasped in time. Especially when the patient has more neck fat and a thicker neck, it is difficult to directly observe the small up and down swings of the head. 2. During the insertion of the endoscope, when the head lifting angle of the patient is determined, the position of the medical staff holding the head will move from the neck to the top of the head area, which will not block the operation of the medical staff in the front and can prevent the left and right swings of the patient's head. However, during the insertion process, the patient's head will naturally droop, which requires continuous lifting of the patient's head, resulting in the suspension of the insertion process.

[0004] In the prior art, some methods use the curved surface of the neck pillow to position the head (CN220256715U, CN115381563A). This method cannot block when the head droops slightly, and once the position of the pillow changes, the head posture will also change. There are also some head positioning devices with overly complex structures (CN220917502U), which are inconvenient to operate in actual use and are not conducive to general anesthesia gastroscopy. Therefore, it is necessary to design a neck device that can stably support the patient's head and lower jaw during general anesthesia gastroscopy, has a simple structure, and is easy to operate.

[0019] Embodiment, referring to Figure 1 、 Figure 2 , the neck support for general anesthesia patients includes a sheath 6 that can be sleeved on the patient's neck. The rear side of the sheath 6 is open, and corresponding connecting pieces 2 are connected to both sides of the opening. Front guide rails 5 and rear guide rails 8 are respectively fixedly installed in the middle parts of the front and rear sides of the sheath 6. A front connecting rod 3-3 that can move up, down, forward, and backward is inserted into the front guide rail 5. The upper end of the front connecting rod 3-3 is hinged to a front support 3-2. A rear connecting rod 1-3 that can move up, down, forward, and backward is inserted into the rear guide rail 8. The upper end of the rear connecting rod 1-3 is hinged to a rear support 1-2. The front support 3-2 and the rear support 1-2 are respectively located on the front and rear sides inside the sheath 6.

[0020] Furthermore, the front guide rail 5 is a hollow cuboid with open upper and lower ends. A front guide groove 5-1 is opened on the end face of the front guide rail 5 facing the outside. A front adjusting rod 4 is inserted into the front guide groove 5-1. The front adjusting rod 4 is a screw rod. The inner end of the front adjusting rod 4 is fixedly connected to the front connecting rod 3-3. A front locking nut 10 is screwed on the outer front adjusting rod 4. There is a certain space between the front connecting rod 3-3 and the inner wall of the front guide rail 5, and the front connecting rod 3-3 can move back and forth inside the front guide rail 5.

[0021] Furthermore, the rear guide rail 8 is a hollow cuboid with openings at both the upper and lower ends. On the outer-facing end surface of the rear guide rail 8, there is a rear guide groove 8-2. Inserted in the rear guide groove 8-2 is a rear adjusting rod 9, which is a screw rod. The inner end of the rear adjusting rod 9 is fixedly connected to the rear connecting rod 1-3. A rear locking nut 11 is screwed onto the outer rear adjusting rod 9. There is a certain space between the rear connecting rod 1-3 and the inner wall of the rear guide rail 8, and the rear connecting rod 1-3 can move back and forth within the rear guide rail 8.

[0022] By manually adjusting the front adjusting rod 4 and the rear adjusting rod 9, the up and down displacements of the front connecting rod 3-3 and the rear connecting rod 1-3 can be driven respectively, so as to adjust the heights of the front support 3-2 and the rear support 1-2. During actual use, adjust the front support 3-2 to touch the lower jaw part, and make the head tilt slightly upwards. Adjust the rear support 1-2 to touch the back of the neck socket. After the heights of the front support 3-2 and the rear support 1-2 are adjusted in place, tighten the front locking nut 10 and the rear locking nut 11 to position the front support 3-2 and the rear support 1-2.

[0023] Furthermore, the front support 3-2 includes a U-shaped body, with the U-shaped opening facing the rear side of the sheath 6. The front connecting rod 3-3 is hinged to the lower end surface of the body. The upper end surface of the body is a curved surface that is higher in the middle and lower on both sides. On the upper side of this curved surface, there is a soft cushion layer. A front outer cover 3-1 is sleeved outside the front support 3-2, and a soft material such as cotton or silica gel is filled between the front outer cover 3-1 and the front support 3-2.

[0024] Furthermore, the rear support 1-2 includes a U-shaped body, with the U-shaped opening facing the front side of the sheath 6. The rear connecting rod 1-3 is hinged to the lower end surface of the body. The upper end surface of the body is curved with the front part lower and the rear part higher and bent inwards. The front end surface of the body is a curved surface protruding towards the front side. Soft cushion layers are provided on both of these curved surfaces. A rear outer cover 1-1 is sleeved outside the rear support 1-2, and a soft material such as cotton or silica gel is filled between the rear outer cover 1-1 and the rear support 1-2.

[0025] Furthermore, a soft layer is provided on the inner wall of the lower part of the sheath 6, and a number of ventilation holes 7 are evenly arranged on the soft layer and the sheath 6. The soft layer can not only fill the gap between the patient's neck and the sheath 6 to enable the stable combination of the sheath 6 and the neck, but also improve the comfort when wearing this application. The sheath 6 can be made of an elastic material such as rubber, polyurethane, PVC, etc.

[0026] When this application is in use, taking the patient's left lateral position as an example, before the patient is anesthetized, the sheath 6 is buckled on the patient's neck with the opening facing the side of the headrest, so that the left side of the patient's neck can naturally contact the headrest. The buckling connecting piece 2 fixes the opening distance of the sheath 6 and makes the soft layer in the sheath 6 closely combine with the lower part of the neck. The connecting piece 2 can be a strap, an elastic band or other soft connecting pieces suitable for this application in the prior art. Subsequently, according to the need of endoscope insertion, the height of the front support 3-2 is adjusted, and the upper end surface of the front support 3-2 is made to contact the patient's mandible. At this time, the upper part of the patient's neck enters the U-shaped opening of the front support 3-2, and the patient's mandible and the two sides are lifted by the front support 3-2. Subsequently, the height of the rear support 1-2 is adjusted according to the elevation angle of the patient's head, and the upper end surface of the rear support 1-2 is made to contact the back of the head, and the front end surface of the rear support 1-2 is made to contact the posterior cervical fossa of the upper part of the neck. Then, the front locking nut 10 and the rear locking nut 11 are tightened to position the front support 3-2 and the rear support 1-2, and then the patient can be anesthetized. During the endoscope insertion process, the patient's head is limited by the front support 3-2 and the rear support 1-2, so that the elevation angle of the head can be kept unchanged. During the endoscope insertion process, when the elevation angle of the head needs to be adjusted, it can be quickly completed by adjusting the heights of the front support 3-2 and the rear support 1-2.

[0027] During the process of adjusting the heights of the front support 3-2 and the rear support 1-2, since the front connecting rod 3-3 and the rear connecting rod 1-3 are limited to move back and forth in the guide rail, the distance between the front connecting rod 3-3 and the rear connecting rod 1-3 can be automatically adjusted according to the thickness of the patient's neck. In order to meet the needs of patients with different neck thicknesses, sheaths 6 with different specifications can be customized. This solution is a conventional technical means, and the specific dimensions are not the invention points of this application and will not be described in detail here.

[0028] The above technical features constitute the embodiments of this application, which have strong adaptability and implementation effects. Non-essential technical features can be added or reduced according to actual needs to meet the needs of different situations.
