The jugular vein puncture head holder 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

1 to 4 , a jugular vein puncture head fixator 100 according to an embodiment of the present invention may include: a fixing belt 10 , an adjusting member 20 and a mounting member 30 .

Specifically, the fixing belt 10 includes a first belt body 11 and a second belt body 12, a portion of the first belt body 11 and a portion of the second belt body 12 are stacked in the thickness direction, and the stacked portion is used to fix the head. The adjustment member 20 connects the first belt body 11 and the second belt body 12 and is used to adjust the length of the stacked portion. The ends of the first belt body 11 and the second belt body 12 that are away from each other are respectively provided with mounting members 30, and the mounting members 30 are used to install and fix the head fixer 100.

The stacked portion of the first belt body 11 and the second belt body 12 cooperates directly or indirectly with the patient's lower jaw to fix the head. The adjusting member 20 can adjust the relative position of the first belt body 11 and the second belt body 12 in the length direction, thereby changing the length of the stacked portion, and then changing the relative distance between the portion used to fix the patient and the two ends of the fixing belt 10, so that the patient's head is offset to the left (which can be the left, upper left or lower left direction) or to the right (which can be the right, upper right or lower right direction) by a certain angle to fully expose the jugular vein puncture site, so as to facilitate the puncture of the patient's jugular vein.

When the head deviation angle is inappropriate, the length of the overlapping part can be adjusted again through the adjustment piece 20 to change the deviation angle of the patient's head. The angle adjustment is convenient and more practical. During the adjustment process, medical staff do not need to touch the patient's head, which improves the convenience of adjustment and reduces the risk of infection for patients.

Furthermore, the tightness of the patient's head can be adjusted by adjusting the length of the stacked portion through the adjusting piece 20, so that the tightness is more comfortable, so as to prevent long-term fixation of the patient's head from causing damage to the patient's facial skin.

In addition, the mounting member 30 can realize the installation and fixation of the head fixator 100, and prevent the fixing belt 10 from loosening, shaking, and other problems during the puncture process, which may cause the patient's head to deviate, thereby affecting the puncture success rate and having a certain adverse effect on the patient's body. For example, the mounting member 30 can be connected to a surgical bed or a bed sheet to realize the installation and fixation of the head fixator 100 on the surgical bed.

The number of the adjusting member 20 includes but is not limited to 1 or 2, as long as the length adjustment of the fixing belt 10 can be achieved. In some embodiments where the adjusting member 20 is 1, the adjusting member 20 can be fixedly connected to the first belt body 11 or the second belt body 12, so that the structure of the head fixer 100 is more streamlined and the production cost is reduced. In some embodiments where the adjusting member 20 is 2, the 2 adjusting members 20 can be fixedly connected to the first belt body 11 and the second belt body 12 respectively. When the fixing belt 10 needs to be adjusted in the length direction, the 2 adjusting members 20 can be used to adjust at the same time, or only one of the adjusting members 20 can be used to adjust, and the adjustment process is more convenient and quick. The method of "fixed connection" here is not limited, and can be sewing with needle and thread, or can be taped, as long as the fixed connection can be achieved. Of course, the adjusting member 20 and the first belt body 11 and the second belt body 12 can also be movably connected, so that the length adjustment can be achieved.

It should be noted that the head fixator 100 is not limited to use by infants and children, but can also be used by adults with limited mobility.

According to the jugular vein puncture head fixator 100 of the embodiment of the utility model, the puncture site can be fully exposed, and the patient's head and neck can be well fixed, the stability is high, and the deflection angle of the patient's head can be adjusted, the practicality is high, the puncture success rate is improved, and it is convenient for medical staff to perform jugular vein puncture.

In some embodiments of the present invention, as shown in Figures 1 to 4, the first belt body 11 and the second belt body 12 are elastic belts, and the elastic force of the elastic belts can be automatically adjusted in a small range, which can avoid the untimely or inaccurate adjustment of the length of the fixing belt 10 causing the fixing belt 10 to be tightened and cause discomfort to the patient or even affect breathing, thereby relieving the pressure on the patient's neck and relaxing the pressure on the neck veins, thereby improving the success rate of jugular vein puncture to a certain extent.

In some related technologies, the patient's head is fixed by sticking paper tape, but some patients are allergic to paper tape, which easily causes facial skin damage and makes it impossible to adjust the head deflection angle. In the above embodiment of the present application, the elastic characteristics of the elastic band are used to improve the fixation effect on the patient's head, so there is no need to use adhesive fixation, which reduces the risk of patient allergies and facilitates repeated adjustment of the head deflection angle.

In some embodiments where the first belt body 11 and the second belt body 12 are elastic belts, as shown in Figures 1 to 4, the first belt body 11 and the second belt body 12 can be disposable bandages, that is, disposable items, to avoid cross infection caused by multiple patients using the same item, which meets the infection control requirements of jugular vein puncture. At the same time, the bandage is made of gauze or cotton cloth, which can well protect patients with allergic constitutions and improve the safety of patients.

In some embodiments of the present invention, as shown in Figures 1 to 4, the width of the stacked portion is 5 cm to 10 cm, which avoids strangulation of the patient's skin due to the stacked portion being too small, and at the same time avoids the stacked portion being too wide, so that the stacked portion is not easy to block the puncture operation area, which is convenient for sufficient disinfection of the puncture operation area, meets the hospital's infection control requirements, and improves the puncture safety for patients.

In some embodiments of the present invention, as shown in FIGS. 1 to 3 , the adjusting member 20 is a buckle 21, one of the first belt body 11 and the second belt body 12 is fixedly connected to the buckle 21, and the other of the first belt body 11 and the second belt body 12 is movably connected to the buckle 21. When the fixing belt 10 needs to be adjusted in the length direction, the length adjustment of the fixing belt 10 can be achieved by pulling the belt body movably connected to the buckle 21 in the length direction.

For example, the buckle 21 is fixedly connected to the first belt body 11 and movably connected to the second belt body 12. When the fixing belt 10 needs to be adjusted, the second belt body 12 is pulled in the length direction to change the length of the stacked portion of the second belt body 12 and the first belt body 11. This can achieve adjustment of the spacing between the ends of the first belt body 11 and the second belt body 12 that are away from each other and the portions of the stacked portions that are used to contact the head, thereby achieving adjustment of the deflection angle of the patient's head and adapting to the size of the head of different patients, so as to fully expose the patient's puncture site and improve the success rate of puncture.

In other embodiments, the adjusting member 20 may be a Velcro or adhesive tape. For example, the adjusting member 20 is a Velcro, which includes two detachable parts and is respectively arranged at the ends of the first belt body 11 and the second belt body 12, for example, one part has a harder bristle surface and is arranged on the first belt body 11, and the other part has a softer fiber surface and is arranged on the second belt body 12. When the fixing belt 10 needs to be adjusted, the first belt body 11 and the second belt body 12 are separated from the pasted parts, and then re-pasted at the appropriate part to adapt to the patient's head size and deflection angle adjustment, which is simple to operate and easy to implement.

In some embodiments in which the adjusting member 20 is a buckle 21, as shown in Figures 1-3, the buckle 21 may include a ring body 211 and a rod body 212 extending radially along the ring body 211, one of the first belt body 11 and the second belt body 12 is connected to the rod body 212, and the other of the first belt body 11 and the second belt body 12 is wrapped around the rod body 212 and fits against one side surface of the ring body 211.

When the belt body movably connected to the buckle 21 is pulled in the length direction, the belt body moves along the length direction around the rod body 212 and in contact with the side of the ring body 211 to achieve the adjustment of the length direction of the fixing belt 10. For example, as shown in FIG3, the second belt body 12 is fixedly connected to the rod body 212, the first belt body 11 is wound around the rod body 212 and in contact with the lower surface of the ring body 211, the ring body 211 is held and the first belt body 11 is pulled in the length direction of the belt body so that the first belt body 11 moves relative to the ring body 211 in the length direction, and the rod body 212 and the ring body 211 can also play a certain role in hindering the movement of the second belt body 12, so that the first belt body 11 is locked when the first belt body 11 is not subjected to the pulling force, so as to prevent the fixation of the head from being affected, thereby improving the accuracy of the puncture site and improving the safety of the patient during the puncture process.

In addition, the installation and fixation of the head fixator 100 by the mounting member 30 also plays an important role in the puncture work of the patient. In some embodiments of the present utility model, as shown in FIG1 , the mounting member 30 is a fixing clamp 31, and the fixing clamp 31 is an integral part, which is not easy to be lost during the use of the head fixator 100, and the fixing clamp 31 is easy to flexibly clamp at any position of the operating table, such as a steel frame, so as to facilitate the installation and fixation of the head fixator 100, and the feasibility is high. Of course, the structure of the mounting member 30 includes but is not limited to the fixing clamp 31, for example, the mounting member 30 may include a detachable and mating snap, etc.

In some embodiments, the first belt body 11 and the second belt body 12 can be fixedly connected to the corresponding mounting member 30 to improve the reliability of fixation. In other embodiments of the present invention, as shown in Figures 1 to 4, at least one of the first belt body 11 and the second belt body 12 is movably connected to the corresponding mounting member 30. For example, the first belt body 11 is movably connected to the corresponding mounting member 30, and the connection method includes but is not limited to a snap connection, a Velcro connection, etc., and the second belt body 12 is fixedly connected to the corresponding mounting member 30. After the head fixer 100 is installed, the first belt body 11 can be preliminarily adjusted in a large range in the length direction relative to the corresponding mounting member 30 to preliminarily adapt to the volume of the patient's head, and then the adjustment member 20 is used to perform further fine adjustments, so as to speed up the adjustment speed of the head fixer 100 and improve the puncture efficiency.

For another example, the first belt body 11 and the second belt body 12 are both movably connected to the corresponding mounting parts 30. After the head fixer 100 is installed, the first belt body 11 and the second belt body 12 can be preliminarily conditioned over a wide range at the same time, further accelerating the adjustment speed of the fixing belt 10 and improving the puncture efficiency.

In some embodiments of the utility model, as shown in FIG. 1-FIG. 2 and FIG. 4, the laminated part may be provided with a fitting 40, and the fitting 40 is provided with a recess 41 for accommodating the chin of the head. For example, the fitting 40 may be bowl-shaped, and the recess 41 is used to support the patient's chin, thereby improving the accuracy of the head deflection angle adjustment during the adjustment of the length of the adjusting member 20, and the recess 41 can protect the patient's chin and improve the patient's comfort. Of course, in some embodiments, the fitting 40 can also be omitted, and the laminated part can directly contact the patient's head, and the friction of the contact area can be used to improve the accuracy of the deflection angle adjustment.

In some embodiments, as shown in FIGS. 1-2 and 4, the fitting 40 is fixedly connected to one of the first belt body 11 and the second belt body 12. For example, as shown in FIG. 4, the bottom of the fitting 40 is fixedly connected to the first belt body 11, and the connection method can be pasting or sewing, etc., as long as the fitting 40 is fixedly connected to the first belt body 11 and does not fall off. In addition, the fitting 40 can also be in the form of a hole provided at the bottom for the belt body to pass through. The fixed connection between the fitting 40 and the belt body can well fix the patient's head angle, reduce the shaking of the fitting 40 relative to the fixing belt 10, and improve the reliability of puncture.
