Example 1

Referring to fig. 1-5, the present embodiment provides a headrest for precisely positioning forehead and chin, comprising a headrest body 100 and a positioning operation mechanism 200, wherein the positioning operation mechanism 200 includes a mandible positioning plate 211 and a forehead positioning plate 212 oppositely disposed on the surface of the headrest body 100, a positioning screw 214 is disposed in a positioning cavity 213 formed on the surface of the headrest body 100 under each of the mandible positioning plate 211 and the forehead positioning plate 212, a positioning block 2140 is threadedly coupled to the surface of the positioning screw 214, the positioning block 2140 is respectively and fixedly mounted to the mandible positioning plate 211 and the forehead positioning plate 212, one end of the positioning screw 214 is rotatably coupled to a driving wheel 215, one end of the driving wheel 215 is coupled to a driven wheel 216, one of the driving wheels 215 is rotatably coupled to a driving motor 217, the driving motor 217 is fixedly coupled to the interior of the headrest body 100, the driven wheels 216 are connected and matched through the rotating shaft 218, when the head of a patient is placed on the surface of the headrest body 100 and is not suitable, the internal driving motors 217 are powered on, so that the driving wheel 215 rotates, that is, the connected positioning screw rod 214 rotates, that is, the positioning screw rod 214 drives the positioning block 2140 to generate lateral displacement, that is, the relative positioning block 2140 and the mandible positioning plate 211 relatively displace, that is, the mandible positioning plate 211 is adjusted in position, meanwhile, the forehead positioning plate 212 connected with the other group of positioning blocks 2140 generates relative transmission displacement through the rotating shaft 218 and the driven wheels 216, that is, the movement of the forehead positioning plate 212 is simultaneously realized while the mandible positioning plate 211 moves, so as to achieve the consistency of accurate positioning, wherein the rotating shaft 218 is inserted into the headrest body 100, so that the driven wheels 216 all obtain stable rotating effect, wherein the headrest body 100 is made of soft silica gel material, and then whole device reaches the comfortable fixed spacing of head to the patient carries out when lying prone head face down when on the sick bed about going on fix a position accurate comfortable effect, and the inside of headrest body 100 is cavity, so that patient's cheek adaptation strengthens practical function.

In this embodiment, grooves 1001 are symmetrically formed on the surface of the headrest body 100, and the grooves 1001 are connected and fitted with a guide pipe. That is, when the patient lies face down, the head is on the surface of the headrest body 100, faces left and right, and the groove 1001 can be used for placing the tracheal cannula to be connected with the nasal cavity of the patient.

In order to solve the problem that the limiting effect of the groove 1001 on the catheter is poor, the catheter limiting assembly 110 is arranged on the surface of the groove 1001, and the catheter limiting assembly 110 comprises a supporting block 112 and limiting plates 113 which are symmetrically arranged, so that the catheter passes through the limiting plates 113 to enable the catheter to be secondarily limited in position inside the groove 1001, and the fixing effect of the catheter is enhanced.

In order to solve the problem that the limiting plate 113 cannot move along with the adjustment and movement of the head, the slider 111 is mounted at the bottom of the supporting block 112, the slider 111 is in sliding connection with the groove sliding cavity 1002 formed in the surface of the groove 1001, so that after the head is adjusted in the front and back positions, the limiting plate 113 is moved by synchronously moving the slider 111, that is, the catheter can be synchronously positioned at the same horizontal position with the nasal cavity of the patient, even if the catheter is connected with the nasal cavity of the patient.

In order to enable the limiting plate 113 to enable the catheter to obtain an excellent limiting effect as much as possible, the size of the limiting plate 113 is matched with that of the catheter, so that the current medical catheter can be matched, attached and connected, and the catheter can be stably connected.

In order to solve the problem that the patient carries out conduit transportation oxygen, the lower influence patient's of its oxygen temperature inhales body and feels, the inside one end of recess 1001 is provided with conduit humidification storehouse 120, the surface of conduit humidification storehouse 120 articulates through the import of seting up has door plant 121, wherein place the inside in conduit humidification storehouse 120 with the hot water stream by the import, close door plant 121, when the patient is connected on the oxygen hose, oxygen carries out humidification and heating before inputing patient's nasal cavity, make the inspiratory oxygen of patient obtain mildly, the difficult patient personnel of breathing of being convenient for use, certain protection patient's effect has been reached.

In order to solve the problem that the conduit humidifying bin 120 cannot be heated after water flow is cooled to affect use, a circular cavity 1201 is formed in the surface of the conduit humidifying bin 120, and an electric heating pipe 1202 is arranged inside the conduit humidifying bin 120, so that the conduit penetrates through the cavity 1201 and is convenient to use; moreover, the electric heating pipe 1202 is powered on, so that the internal water flow can be heated after being cooled for a long time, and long-time humidification and heating operations are facilitated.

The headrest that can carry out accurate location to forehead and chin of this embodiment is when specifically using, pass through the power of initiative motor 217, action wheel 215 drives positioning screw 214 and rotates, positioning screw 214 drives locating piece 2140 and takes place the displacement, locating piece 2140 and lower jaw locating plate 211 relative displacement, lower jaw locating plate 211 obtains position control, it takes place transmission displacement to make the forehead locating plate 212 that another group of locating piece 2140 connects to take place through axis of rotation 218, again through running through the pipe by limiting plate 113, the inside hot water stream of putting into of pipe humidification storehouse 120 deepens and heats the inside fluid of pipe, just adsorb comparatively comfortable fluid for the patient.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It should be understood by those skilled in the art that the present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only preferred examples of the present invention, and is not intended to limit the present invention, and that the present invention can have various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications all fall into the scope of the claimed invention.
