Description
Technical field
The utility model is related to a kind of medical instruments, and in particular to a kind of central vein catheter support device.
Background technology
Central venous catheter (PICC) as chemotherapy of tumors and the important access of parenteral nutrition, have become it is a kind of it is ripe,
The medical instrument that the central vein catheter of safety uses.Because its is easy to operate, safety, puncture success rate are high, can make the long period
With reduction patient punctures pain, the advantages that being easy to be accepted by patients, is widely applied clinically.
Central venous catheter is usually embedded in inboard arm at oxter, whole during hub venous catheter posting
Outside arm is constantly exposed to, if in more arctic weather, arm, which is cooled, will cause arm to shake, then is unfavorable for centre pipe
Merging；Arm is cooled, vessel retraction, is also unfavorable for finding central vein.
In addition, since hub venous catheter posting is in inboard arm, inboard arm is generally directed toward lower section after arm stretches,
Therefore, it is necessary to patient itself arms firmly the inside of arm to be made to turn over as possible, and during setting pipe for a long time, patient itself is difficult
To keep prolonged force state, then under natural reaction, the inside of arm will often downwardly turn over, to give medical care people
The pipe operation of setting of member is made troubles.
Utility model content
There can be warming and fixed function central vein to set arm the purpose of this utility model is to provide a kind of
Effective support device.
In order to achieve the above objectives, the base case of the utility model is as follows：
Central vein catheter support device includes pedestal and the fixing sleeve on pedestal, and the pedestal is equipped with branch
Frame is rotatably connected to rotary sleeve on the holder, and holder is equipped with the fixing piece for fixing rotary sleeve, the fixing sleeve
One end is fixed with rotary sleeve；The other end of the fixing sleeve, which offers, sets pipe handle hole, and fixing sleeve makes fixation for double-layer structure
Set is internal to form air cavity, and fixing sleeve is equipped with the air inlet being connected to air cavity；Wind turbine, the outlet air of wind turbine are additionally provided on the pedestal
Electric heating wire is equipped at mouthful, and the air outlet of wind turbine is connected to air inlet.
The principle of this programme central vein catheter support device is：
In the present solution, rotary sleeve stretches into for the arm of people, rotary sleeve is the front end of fixing sleeve at one end, and arm from
Fixing sleeve rear end is stretched into and is stretched out from fixing sleeve front end, and forearm is in rotary sleeve.When arm is put into fixing sleeve, and make hand
After pipe handle hole is set in the inside alignment of arm, start wind turbine, while electrothermal wire heating, to make wind turbine blow out hot wind.Wind turbine bloats
Hot wind is simultaneously entered by air inlet in air cavity so that fixing sleeve is expanded to both sides, therefore the inner wall of fixing sleeve is adjacent to the hand of patient
Arm can prevent arm relative to fixing sleeve movement or rotation with this；Then rotary sleeve is rotated, then rotary sleeve will drive fixing sleeve
Front rotates, and to make fixing sleeve drive roll over, then can turn over the inside of arm as possible, then will be revolved by fixing piece
Pivoted housing is fixed, then the inside of patient's arm can be made towards medical staff, be conducive to medical staff and carry out setting pipe operation, and setting pipe
In the process, arm is fixed by rotary sleeve, thus prevents the arm motion of patient, is impacted to the operation of medical staff.
This programme generate advantageous effect be：
（One）Hot wind is blasted in the air cavity of fixing sleeve so that arm is wrapped up by hot-air, and arm is prevented to be cooled；In addition, heat is empty
Gas is also prevented from vessel retraction, carries out setting pipe operation to be conducive to medical staff.
（Two）In order to enable the palm to across rotary sleeve, then rotary sleeve is bigger than forearm, and so that fixing sleeve is expanded by inflation
Can then fixing sleeve be made to wrap up arm, to which rotary sleeve can indirectly fix solid forearm, then this can by fixed rotary sleeve
By arm fixation, prevent arm mobile or rotation.
Preferred embodiment one：It is advanced optimized as to base case, the fixing sleeve is made of elastic material, wind turbine
It is equipped with pressure sensor at air outlet, and is equipped with the electric-controlled switch that can make wind turbine deenergization, and electric-controlled switch and pressure sensing
Device is electrically connected, and valve is equipped at the air inlet.Since fixing sleeve is made of elastic material, when air cavity of the wind turbine into fixing sleeve
When inflation, when the pressure in air cavity gradually increases, the pressure feedback to pressure sensor is automatically controlled after pressure reaches certain value
Automatic switchover is kept wind turbine out of service by switch, and to can reach energy-efficient purpose, the valve being then shut off at air inlet then may be used
The pressure in fixing sleeve air cavity is set to remain unchanged.
Preferred embodiment two：As advanced optimizing to preferred embodiment one, the valve is check valve, on the fixing sleeve
It is additionally provided with the gas vent being connected to air cavity, air bleeding valve is equipped at the gas vent.Valve at air inlet is set as check valve, when
After wind turbine is out of service, check valve will turn off, from the gas overflowing prevented in air cavity；After the completion of setting pipe, exhaust is opened
Valve is released the gas in air cavity, then can be taken out arm out of fixing sleeve.
Preferred embodiment three：As advanced optimizing to preferred embodiment two, the bottom of the pedestal is equipped with sucker, by pedestal
It is fixed on the table by sucker, so as to which the quality of pedestal is made lighter, is conducive to move the device.
Preferred embodiment four：As advanced optimizing to preferred embodiment three, the rotary sleeve includes inner ring and outer rings, outer shroud
It is connected with holder pivots, outer shroud periphery is equipped with ratchet, and holder is equipped with the pawl corresponding to ratchet；The inner ring is rotated with outer shroud
Connection, inner ring periphery are equipped with spring mounting hole, and outer shroud inner circumferential is equipped with spherical concave surface corresponding with spring mounting hole, spring mounting hole
It is interior to be equipped with spring, it is equipped with the steel ball coordinated with spherical concave surface between spring and spherical concave surface, fixing sleeve is fixed with inner ring.
Due to the spring installed in inner ring by steel ball top pressure on outer shroud, when steel ball exactly corresponds to spherical concave surface, outside
Ring will drive inner ring to rotate together；When the power for the negative direction that inner ring is subject to is excessive, spherical female will be compressed in face of the pressure of steel ball
Spring, to steel ball separable spherical concave surface, i.e. outer shroud cannot drive inner ring to rotate.Since holder and outer shroud are equipped with phase interworking
The ratchet and pawl of conjunction, therefore outer shroud can only one-directionally rotate.In operation, outer shroud is rotated, then inner ring rotates drive arm simultaneously
Overturning, after arm is overturn to a certain extent, arm increases the active force of inner ring, then being rotated further outer shroud cannot drive again
Inner ring rotates, and stop operating outer shroud at this time, and due to the effect of pawl, outer shroud cannot invert, so as to by arm fixation.
Preferred embodiment five：As advanced optimizing to preferred embodiment four, it is fixed with rotational handle on the outer shroud, is passed through
Handle is conducive to rotate outer shroud.
