When not in use, the plastic film covers the hydrocolloid to protect the hydrocolloid. When in use, the plastic film is torn off, and the hydrocolloid is used to bond the silicone sheet 2 to the skin on the patient's forehead, so that the hard plastic plate 1 is fixed on the patient's forehead.

[0042] The connector 3 is integrally formed and arranged on the hard plastic plate 1, and a connecting portion 5 is provided at one end of the connecting rod 4, and the connecting portion 5 is detachably fixedly connected to the connector 3. In this way, the connecting rod 4 can be conveniently disassembled and assembled on the hard plastic plate 1. When the connecting rod 4 is mounted on the hard plastic plate 1, the connecting rod 4 is placed above the patient's face. An elastic tube clamp 6 is connected to the other end of the connecting rod 4, and a bayonet is provided on the elastic tube clamp 6, and the bayonet is used to clamp a medical cannula.

[0043] Before inserting the cannula into the patient's body, the hard plastic plate 1 is first bonded and fixed to the patient's forehead with the help of hydrocolloid and silicone sheet 2, and then the connecting part 5 is connected to the above-mentioned connector 3. At this time, the above-mentioned elastic tube clamp 6 is placed above the patient's mouth, and the cannula is inserted into the patient's body through the patient's mouth, and the cannula is directly clamped into the clamping port of the above-mentioned elastic tube clamp 6. That is, after the cannula is inserted into the patient's body, the medical staff only needs to clamp the cannula into the clamping port to fix the cannula on the patient's face. In this way, the cannula can be quickly and firmly fixed on the patient's face in a very short time after the cannula is inserted into the body, and the operation of fixing the cannula is simple and convenient, and has strong practicality. In addition, for patients who need to insert the cannula multiple times, when the cannula needs to be removed, it is only necessary to remove the cannula from the elastic tube clamp 6, and the cannula can be easily released. In addition, in idle time (referring to the time when the cannula treatment is not used), the connecting part 5 and the connector 3 can be separated, and the hard plastic plate 1 and the connector 3 are left on the patient's forehead. When the cannula treatment is used next time, the connecting rod 4 can be directly assembled on the connector 3, and then the cannula can be quickly fixed. Of course, the connecting rod 4 can also be left unremoved during idle time, so that the cannula can be fixed more quickly next time. Of course, in specific use, the hard plastic plate 1 can also be pre-installed on the patient's forehead, and then the cannula is inserted into the patient's body, and finally the connecting rod 4 is installed on the hard plastic plate 1, and finally the cannula is clamped in the bayonet of the elastic tube clamp 6 on the connecting rod 4.

[0044] Optionally, the connector 3 comprises a block 31 and a stud 32, wherein:

[0045] The block 31 is integrally formed on the hard plastic plate 1 , and the stud 32 is integrally formed on the block 31 , and the stud 32 is located at the center of the block 31 .

[0046] A through hole is provided in the connecting portion 5, and the through hole includes a first section and a second section that are connected.

During installation, the block 31 is accommodated in the first section, and the stud 32 passes through the first section and the second section in sequence and extends out of the connecting portion 5. Then, a locking nut 7 is screwed on the stud 32, and the connecting portion 5 is pressed against the hard plastic plate 1 by the locking nut 7, thereby realizing a detachable fixed connection between the connector 3 and the connecting portion 5. The cooperation between the block 31 and the first section can position the connecting rod 4 during and after installation, so that the elastic pipe clamp 6 is placed in the correct position.

[0047] When in use, the connection and disconnection of the connecting portion 5 and the connecting head 3 can be easily achieved by only twisting the locking nut 7 , thereby achieving rapid assembly and disassembly of the connecting rod 4 and the elastic pipe clamp 6 on the hard plastic plate 1 .

[0048] The locking nut 7 includes a pressing tube 71 and a handle 73. The inner wall of the pressing tube 71 is provided with an internal thread for engaging with the stud 32. Thus, the pressing tube 71 is actually an internal threaded tube. The connecting portion 5 is pressed by the pressing tube 71 screwed on the stud 32. One end of the pressing tube 71 is blocked by a sealing plate 72. The handle 73 is integrally formed on the outer wall of the pressing tube 71. With the help of the handle 73, it is more convenient for medical staff to rotate the locking nut 7.

[0049] Optionally, the connecting portion 5 comprises a circular block 51 and a connecting block 52, wherein:

The two connecting rods 4 can enhance the connection strength between the mounting block 8 and the connecting block 52, so that the elastic pipe clamp 6 is more firmly connected to the hard plastic plate 1, so as to avoid the elastic pipe clamp 6 from shaking or position shifting for no reason when in use.

[0052] Optionally, the connecting rod 4 includes a straight section 41 and a curved section 42, one end of the straight section 41 is connected to the connecting block 52 by heat-melting, and the straight section 41 extends to the side of the connecting block 52, one end of the curved section 42 is integrally formed with the other end of the straight section 41, and the other end of the curved section 42 is connected to the mounting block 8 by heat-melting. The two connecting rods 4 are respectively located on both sides of the connecting block 52. At this time, the connecting block 52, the two connecting rods 4 and the mounting block 8 form a closed-loop structure similar to a triangle, which has high structural strength and further avoids the elastic tube clamp 6 from shaking or position shifting for no reason during use. When in use, the two connecting rods 4 are respectively located above the two sides of the patient's face.

[0053] Optionally, the elastic tube clamp 6 in this embodiment is a stainless steel spring or a circular arc plate made of hard plastic, the arc of the circular arc plate is greater than 180°, the inner hole of the circular arc plate constitutes the above-mentioned bayonet, and the inner hole diameter of the circular arc plate (that is, the inner diameter of the circular arc plate) is adapted to the above-mentioned insert tube, and when in use, the insert tube is inserted into the above-mentioned bayonet through the opening of the circular arc plate. The outer arc wall of the circular arc plate is bonded and fixed to the above-mentioned support rod 81, so that the elastic tube clamp 6 is firmly connected to the support rod 81. When the insert tube is clamped in the above-mentioned bayonet, the elastic force of the circular arc plate is used to press the insert tube.

[0054] An anti-slip rubber sheet 9 is bonded to the inner arc wall of the arc plate (ie, the inner hole wall of the arc plate). With the help of the anti-slip rubber sheet 9, the friction force applied to the outer wall of the cannula can be further increased, thereby better clamping the cannula.

[0055] As another implementation of this embodiment, hydrocolloid may also be provided on the inner arc wall of the arc plate. When the insert tube is placed in the bayonet of the arc plate, the outer wall of the insert tube is bonded and fixed to the inner arc wall of the arc plate through the hydrocolloid.

[0056] Different types of cannula quick fixers are configured for patients with different face shapes, and the vertical distances between the mounting blocks and the connecting blocks of different types of fixers are different.

[0057] Embodiment 2:

Moreover, a threaded through hole is opened in the tube wall of the outer tube 44 near the other end thereof, and a hand-tightening bolt 10 is screwed in the threaded through hole. The hand-tightening bolt 10 is used to lock the inner shaft 43 to the above-mentioned outer tube 44.

[0060] When in use, the hard plastic plate 1 is installed on the patient's forehead in advance, and then the connecting part 5 is installed on the connecting head 3. At this time, the telescopic rod is in a retracted state, that is, the mounting block 8 is located near the outer tube 44. When the cannula is inserted into the patient's body, the medical staff pulls the inner shaft 43 out to make the elastic tube clamp 6 on the mounting block 8 clamp the cannula, and then tightens the hand bolt 10 to fix the inner shaft 43 to the outer tube 44 using the hand bolt 10.

[0061] It should be noted that, with the help of the connecting block 52 of the connecting portion 5, the connecting rod 4 is located above the patient's nose.

[0062] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto.
