Referring to fig. 1-4, the present invention provides a technical solution: the special safety fixing device for the venous indwelling needle comprises a device main body 1, a forearm fixing plate 2 and a main air cavity 3, wherein one side of the device main body 1 is fixedly connected with a fixing groove 8, the inner part of the fixing groove 8 is fixedly connected with the forearm fixing plate 2, the other side of the bottom of the forearm fixing plate 2 is connected with a fixing bolt 9 in an embedding manner, one side of the forearm fixing plate 2 is fixedly connected with a fixing belt groove 6, the inner part of the fixing belt groove 6 is fixedly connected with a fixing belt 4, the other side of the fixing belt 4 is fixedly connected with a second fixing belt 7, the other side of the device main body 1 is fixedly connected with a main air cavity 3, the inner part of the main air cavity 3 is connected with an air duct 11 in an embedding manner, one side of the main air cavity 3 is fixedly connected with a main air duct groove 12, the inner part of the main air duct groove, a limiting belt groove 16 is fixedly connected to one side of the middle part of the main air duct groove 12, a limiting belt 17 is fixedly connected to the inside of the limiting belt groove 16, and a device bottom surface 18 is fixedly connected to the bottom of the device main body 1.

Preferably, the middle part fixedly connected with antiskid face 20 of device bottom surface 18, current vein is kept somewhere needle fixing device stability and is not good, and when the device was directly put on the desktop and is used, the device skidded easily, probably leads to vein to keep somewhere the needle and follow the roll-off in patient's blood vessel, and through setting up antiskid face 20, antiskid face 20 can increase the friction between device bottom and the desktop, prevents that the device from taking place the phenomenon of skidding, has improved the stability of device.

Preferably, sucking disc 19 can be dismantled to the opposite side fixedly connected with of antiskid face 20, if the device need be when the smooth desktop in surface work, relevant medical personnel can install in the device bottom dismantling sucking disc 19, have played a fixed action, prevent because the desktop is too smooth, lead to the device to take place to remove, have played the guard action to the patient.

Preferably, the surface through connection of fixed band 4 has bleeder vent 5, and when medical personnel utilized fixed band 4 to fix patient's forearm for a long time, the patient probably felt the discomfort because fixed band 4 is ventilative to cause patient's restlessness, through setting up bleeder vent 5, bleeder vent 5 can make patient's skin communicate with each other with external environment, has increased fixed band 4's gas permeability, has improved patient's travelling comfort.

Preferably, the top fixedly connected with foam-rubber cushion 10 of forearm fixed plate 2, if the patient directly puts the arm on forearm fixed plate 2, this may arouse patient's discomfort, through setting up foam-rubber cushion 10, foam-rubber cushion 10 texture is soft, the travelling comfort preferred, and foam-rubber cushion 10 installs the surface at forearm fixed plate 2 and can prevent the direct outer wall contact with forearm fixed plate 2 of patient forearm fixed plate.

Preferably, the fixing groove 8 on one side of the device body 1, the forearm fixing plate 2 inside the fixing groove 8, the fixing bolt 9 on the other side of the bottom of the forearm fixing plate 2, the fixing belt groove 6 on one side of the forearm fixing plate 2, the fixing belt 4 inside the fixing belt groove 6 and the second fixing belt 7 on the other side of the fixing belt 4 jointly form a forearm fixing mechanism, most of the existing venous indwelling needle fixing devices are not provided with the forearm fixing mechanism, however, in the infusion process of a patient, the venous indwelling needle is easy to slide out of the blood vessel of the patient due to the movement of the forearm, so that medical staff need to help the patient to insert a needle for the second time, and the patient is injured, by arranging the forearm fixing mechanism, the medical staff can place the forearm of the patient on the forearm fixing plate 2 before injection, and then fix the forearm of the patient by using the fixing belt 4 and the second fixing belt 7, so as to prevent the forearm of the patient from moving in the infusion, plays the guard action to the patient, after the infusion, medical personnel still can not hard up gim peg 9 and pull down forearm fixed plate 2 and disinfect the disinfection, prevents that next user from having the risk of infecting.

Preferably, the main air cavity 3 at the other side of the device main body 1, the air duct 11 inside the main air cavity 3, the main air duct groove 12 at one side of the main air cavity 3, the main air duct 13 inside the main air duct groove 12, the air inflation bag 14 at the bottom of the main air duct 13, the air deflation valve 15 at the bottom of the air inflation bag 14, the limit belt groove 16 at one side of the middle part of the main air duct groove 12 and the limit belt 17 inside the limit belt groove 16 jointly form a vein indwelling needle limit mechanism, in the prior art, most patients use adhesive tapes to fix the vein indwelling needle during the infusion process, which easily causes discomfort of the patients, and once the patient sweats, the adhesive tapes are easy to fall off to cause the vein indwelling needle to slide off, by arranging the vein indwelling needle limit mechanism, medical personnel can use the air inflation bag 14 to inflate the main air duct 13 after helping the patients to complete the insertion of the needle, so that the palm of the patients can be fixed by the main air cushion at, meanwhile, the venous indwelling needle is wrapped, after palm fixing of a patient is completed, medical workers can fix the venous indwelling needle by using the limiting belt 17 inside the limiting belt groove 16, and further the venous indwelling needle is prevented from sliding off, so that the adhesive tape is prevented from being used by the fixing method, and the comfort of the patient is improved.

The working principle is as follows: firstly, by arranging the forearm fixing mechanism, medical personnel can put the forearm of a patient on the forearm fixing plate 2 before injection, then fix the forearm of the patient by using the fixing band 4 and the second fixing band 7, prevent the forearm of the patient from moving randomly in the infusion process, protect the patient, and loosen the fixing bolt 9 to detach the forearm fixing plate 2 for sterilization and disinfection after the infusion is finished, so that the next user is prevented from having infection risk;

then, by arranging the venous indwelling needle limiting mechanism, after the medical care personnel help the patient to complete needle insertion, the main air pipe 13 can be inflated by using the inflation bag 14, so that the palm of the patient can be fixed by the main air cavity 3 and the air cushion at the top of the main air cavity 3, and the venous indwelling needle is wrapped at the same time, after the palm of the patient is fixed, the medical care personnel can fix the venous indwelling needle by using the limiting belt 17 in the limiting belt groove 16, so that the venous indwelling needle is further prevented from sliding off, and the fixing method avoids using an adhesive tape and improves the comfort of the patient;

then, the skin of the patient can be communicated with the external environment through the air holes 5 arranged on the fixing belt 4, so that the air permeability of the patient is improved, and the comfort of the patient is improved;

then, by arranging the anti-slip surface 20, the anti-slip surface 20 can increase the friction between the bottom of the device and the desktop, prevent the device from slipping and improve the stability of the device;

finally, through setting up foam-rubber cushion 10, foam-rubber cushion 10 texture is soft, and the travelling comfort preferred, foam-rubber cushion 10 install can prevent that patient's forearm from direct and forearm fixed plate 2's outer wall contact on the surface of forearm fixed plate 2, and this is exactly this kind of vein and keeps somewhere special safe fixing device's of needle theory of operation.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
