Abstract
Aiming at the situation that a device for fixing a sengstaken-blakemore tube is unavailable, the invention discloses a multi-dimensional adjustable traction fixing rack for the sengstaken-blakemore tube and a nursing bed with the multi-dimensional adjustable traction fixing rack. The multi-dimensional adjustable traction fixing rack consists of a support base, a pulley, an adjusting rod, a limiting rack, a weight, a traction rope, a limiting ball, a fixing base, a horizontal moving locking knob, a lifting locking knob and a rotation locking knob. The nursing bed with the multi-dimensional adjustable traction fixing rack comprises a hospital bed and a fixing bracket. The multi-dimensional adjustable traction fixing rack has the beneficial technical effects that by adopting the multi-dimensional adjustable traction fixing rack, the convenience and the security can be improved when the sengstaken-blakemore tube is adopted for nursing of hemostasis by compression, meanwhile the comfort degree of the sengstaken-blakemore tube retained in a patient can be increased, the treatment effect can be improved, and the patient can be recovered rapidly.
Description
Technical field
The present invention is technical field of medical auxiliary equipment and in particular to the adjustable traction of multidimensional for Sengstaken-Blakemore tube is fixed
Frame and adopt its care bed.
Background technology
Sengstaken-Blakemore tube indwelling hemostasis by compression is using air bag mechanical pressure oesophagus, stomach, orifice of the stomach and oesophagus respectively
Hypomere rupture cirso- and play anastalsis, be treatment the simple and effective side of esophageal varices massive haemorrhage
Method and clinical conventional emergency measures, are preferably used for the out of contior bleeding of medicine or endoscope treatment uses, to strive for when invalid
Time prepares other treatment measure, is for a kind of simple, treatment method safely, conveniently, economic, especially in cirrhosis portal vein
High pressure causes esophageal varices massive haemorrhage acute stage, and Compressive Hemostasis are notable, can timely and effectively save trouble
Person's life.Therefore nursing staff is just particularly important for the nursing of indwelling Sengstaken-Blakemore tube.Three chambeies of Clinical practice at present
Two capsule Guan Weiyi root silicone tubes, have three chambeies, and a chamber is circular stomach air bag, oppress stomach bottom after inflatable 150-200ml；One chamber is
Oblong esophageal balloon, oppresses distal esophagus after inflatable 100-150ml；One chamber is stomach tube, can give stomach and intestine through this chamber
Decompression discharges pneumatosis hydrops in stomach, in order to rinse gastral cavity or injection of medicine.Sengstaken-Blakemore tube wants to play the purpose of hemostasis by compression,
Need lasting tractive force, trailing weight is about 0.5kg.
During clinical Canal Nursing, nursing staff does not have special Sengstaken-Blakemore tube fixed traction equipment, they
Often can only gather materials on the spot, with Infusion support as bracing frame, use water as traction with 500ml transfusion, made with medical lining band
For pull rope.There are a lot of problems in use, mainly have a following deficiency:
1. traction orientation is fixed, the no any mobility of patient, is unfavorable for disease recovery and pressure sore easily occurs；
2. traction angle is difficult to adjust, and tractive force cannot correctly transmit, and traction effect is not good enough；
3., there is potential safety hazard in the non-professional bearer cable of pull rope, easy fracture；
4. pull rope turning point fixes stress point for Infusion support, is easily affected by burst external force, causes patient's tension injury or nothing
Effect treatment；
5. traction is liquid, affected by environment, easily causes the unstable of tractive force.
In sum, in order to preferably using Sengstaken-Blakemore tube and simplify and optimize clinical nursing activity, it is desirable to provide one
Plant adjustable Sengstaken-Blakemore tube traction fixation frame.

The invention aims to preferably nursing Sengstaken-Blakemore tube puts the patient of pipe, simplify nursery work, increase pipe
Road nursing safety.This kind of Sengstaken-Blakemore tube traction fixation frame is reasonable in design, structure is simple, safe operation, easy to use, saves
Manpower is it is ensured that safety.
The present invention can be placed in tailstock frame or bed side guardrail optional position, and adjustable-height (0-30cm) carry pulley
The device of axle, we also referred to as draw fixing axle, and by the device of this pulley spindle, we both can adjust the orientation of traction,
The angle of traction can also be adjusted, be no longer that patient body position follows device to be forced to fix, but can be random according to patient body position
Adjust fixed mount, to ensure that patient body position's is comfortable, avoid the body pressurized generation causing pressure sore in same position for a long time simultaneously；
Pull rope of the present invention is nylon material, it is to avoid pull rope surprisingly ruptures in use, causes other bad things
The generation of part；And due to angle position of the present invention adjustable (rotation and translation), pull rope will not be scratched or is subject to extra hindering
Power, therefore, it is possible to be transferred to Sengstaken-Blakemore tube without loss by the pulling force being produced by counterweight.Sengstaken-Blakemore tube on the market at present
Fixing device lacks this function, can produce extra resistance to pull rope, leads to power and the reality being applied on Sengstaken-Blakemore tube
The power needing does not correspond.
The present invention is provided with safety buckle device, effectively prevent traction fixing device and remains to when burst is unexpected keep effectively
Tractive force and reduce burst the infringement to patient for the external force.
The present invention when mounted, only need to snap in fixed seat 9 on the fixed support 14 of sick bed 15, regulate relative position
Afterwards, carry out fastening with fixed knob 10.This structure can be adapted to most of sick bed with cylindrical holder, has general wildcard
Property.
Support base 1 is " z " type structure, and one end is used for supporting pulley 2, and pulley can be allowed to rotate freely.Other end and tune
Pole 3 connects, two grades of bars that adjusting rod 3 is made up of for 300mm stainless steel tube two different-diameters, length, and lower end passes through solid
Reservation 9, tightening knob below can adjust whole two grades of bars and freely move up and down, and knob above is then to adjust inside directly
The less pole in footpath freely stretches, so that adjusting in the range of the adjustable-height 200-600mm of entirety, is adjusted to suitable position
Can be locked by locking knob 11 after putting.
Adjusting rod 3 bottom fills a cap fall prevention 13, prevents user from so that adjusting rod is departed from and fixes
Seat, more hommization.
Position-limited rack 4 adopts " v " type structure, and the sunk screw of 4 m2 × 5 in one end is fixed in support 1, and the other end wears traction
Rope.Pull rope is provided with a positive stop bead, and when being to prevent from untiing pull rope to patient, patient is pulled in the deadweight of counterweight 6.
Pull rope 7 adopts macromolecule nylon material it is ensured that solid, durable；During assembling, through position-limited rack 4 notch, bypass cunning
Take turns 2 one end, connect counterweight, other end connects Sengstaken-Blakemore tube.
Adjusting rod 3 and can support 360 ° of " free " rotations between 1 to adjust.In the case of ensureing effectively to draw, keep leading
Messenger 7 is hanging and pull rope 7, pulley 2 should with limbs in line after.Positioned locked by rotational lock knob 12.
Support 1 side that one handle 5 is installed, design takes into full account Study on Man-Machine Function scientific principle is read.
Multidimensional for Sengstaken-Blakemore tube of the present invention is adjustable traction fixation frame and the care bed research and development using it, obtain
Obtain state natural sciences fund general project " the supportive forecast model looking after demand of patients with lung cancer and its Intervention Mechanism research "
(bullets: 81573017), and Anhui Province's Nsfc Projects " operation of liver cancer patient's disease based on Omaha system
