Referring to fig. 5, the inner side of the head beam 1 can also contact with the top of the head, so as to further increase the clamping and fixing effect of the whole head beam 1 on the head, and the head beam 1 has a certain elasticity, which not only can provide a clamping force for clamping the head itself, but also can deform within a certain range to adapt to different head types.

The head beam 1 comprises a main beam 11 in an arc shape and a side beam connected with the main beam 11 in a sliding way, and the tail ends of the side beam are connected with a contact part. In the present embodiment, the contact portion and the side member are bonded together using an adhesive. In other embodiments, a snap connection or a bolt connection may be used between the contact portion and the side member.

In order to prevent the problem of the clamping head and to enable direct contact with the skin of the head, the head beam is ergonomically improved in this embodiment, with a contact portion being provided on the inner side of the head beam.

The contact portion in this embodiment is connected to the inside of the side member.

In other embodiments, the contact portion may also be connected below the end of the side member.

In the present embodiment, each contact portion is made of a single piece of rubber material and bonded integrally with the side member; in order to adapt to the needs of human body, the rubber adopted by the contact part in the embodiment is silica gel which is relatively soft and has no problem of direct contact with skin; alternatively, food grade nitrile rubber may be used.

In other embodiments, leather or plastic may also be used as the material of the contact portion.

In order to further play the role of the anti-chuck of the contact part, the main beam and the side beam can be connected in a telescopic mode, and the elastic modulus of the head beam is increased in a mode of expanding the length of the head beam, so that the chuck is prevented.

The side beams comprise a first side beam 12 and a second side beam 13, the first side beam 12 is connected with one end of the main beam 11 in a sliding mode, the second side beam 13 is connected with the other end of the main beam 11 in a sliding mode, and the tail end of the first side beam 12 and the tail end of the second side beam are connected with a contact portion. It can be understood that the sliding side beam is the key to adapt the main beam 11 to different head sizes, so that a relatively stable connection between the side beam and the main beam 11 needs to be maintained all the time, and the side beam is prevented from deforming in the moving process. In this embodiment, the side beams and the main beams 11 are connected by means of insertion. The sliding connection between the side beams and the main beam 11 is made by a sliding expansion/contraction adjustment device. Specifically, the end of the side beam is provided with a connecting member, the connecting member is clamped on the main beam 11, and the connecting member is C-shaped to ensure that the connecting member can slide along the main beam 11 without departing from the main beam 11.

Specifically, the end part of the side beam is provided with a C-shaped frame, and the main beam 11 penetrates through the C-shaped frame, so that the side beam and the main beam 11 can move in a relative sliding manner.

In another embodiment, the connection between the side beams and the main beam 11 may also be in other forms of insertion, for example, a slot is provided as a track in the main beam 11, and the side beam is inserted into the slot.

In this embodiment, the main beam 11 is provided with a groove as a rail, into which the side beam is inserted; the rail formed in the groove has a convex section shape, and the section shape of the part of the side beam inserted into the groove also has a convex section shape, so that the groove and the side beam in the shape can clamp the side beam to prevent the side beam from separating from the groove.

In this embodiment, the two clamping members 2 are connected to two ends of the head beam 1, the two clamping members 2 are respectively located at one end and the other end of the head beam 1, and when the embodiment is used, the two drainage containers can be clamped and connected to the two clamping members 2 at the same time.

In a further embodiment, the clamps 2 are connected to either end of the head beam 1, and one clamp 2 is provided, so that in this embodiment, one clamp 2 connected to one end of the head beam 1 engages a drainage container only at its location.

The part of the side of the opening of the clamping piece 2 has elasticity, the width of the opening is not less than the width of the drainage container, and the width of the drainage container is also the diameter of the drainage container.

In this embodiment, the clamping member 2 is a clip, a groove adapted to the shape of the outer surface of the drainage container is formed on the inner side of the clip, and the notch is a clamping portion of the clip.

More specifically, in order to adapt to the current drainage container that has the utricule, when the inboard of clip is equipped with the recess that suits with drainage container surface shape, the groove face of recess still is equipped with the bump to the frictional force of the groove face of reinforcing recess, the recess is when providing the space that the drainage container passed, and the drainage container that also can be right carries on spacingly in the axial.

It should be noted that the drainage container in this embodiment is a container containing drainage liquid, and the diameter of the container is generally 10mm to 20mm, and the volume of the container is 20ml, that is, the clamping member 2 in this embodiment can clamp a cylindrical container with a volume of at least 20ml, and the drainage container can be a syringe.

It should be noted that the main beam 11 in this embodiment includes an arc-shaped housing molded from plastic, which has a certain elasticity to facilitate the use of different synchronous shapes; the side beam includes a housing molded from plastic and having a degree of resiliency.

In yet another embodiment, to increase the strength of the main beam 11, metal strips may be provided in the internal cavity of the housing of the main beam 11 and/or the side beams to increase the structural strength.

Considering that the patient is in a lying position most of the time during the use of the present embodiment, the head beam 1 can be reduced appropriately in consideration of the weight.

In this embodiment, the side member includes a latch arm extending downwardly from the upper portion. As shown in fig. 2 when viewed from the side, an arcuate structure is formed at the end of the latch arm.

More specifically, in the present embodiment, the first side member 12 is connected to the first latching arm 121, the second side member 13 is connected to the second latching arm 131, the first latching arm 121 is connected to the first contact portion, and the second latching arm 131 is connected to the second contact portion.

The facial surgery drainage device holder configured as described above is attached by attaching the head bridge 1 to the head and pressing the contact portion near the ear. Meanwhile, as shown in fig. 5, the facial surgery drainage device holder is safely worn on the head because the contact portion is relatively flat and exposed near the ear.

The contact portion may have a shape other than the shape shown in fig. 1.

For example, fig. 4 shows the contact portion in a C-shape.

Fig. 3 shows a contact portion in the shape of a strip.

The tail end of the head beam can be fixed to the head in a clamping force providing mode, and can also be fixed to the ear in a connecting mode, specific selection of various fixing modes is determined according to specific conditions of patients, a clamping and fixing method can be adopted under the condition that the ears are not convenient to use the clamping device, and use experience of the patients is effectively improved.
