Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a restraint device for preventing patients from accidentally removing tubes. Background Art

[0002] During postoperative care, various deep venous catheters or drainage catheters will be used. Due to impaired consciousness such as confusion, irritability or non-cooperation, the patient's hands will be agitated or excited. In the absence of sedation, unplanned extubation may occur and cause secondary injury to the patient.

[0003] Clinically, patients with impaired consciousness are restrained to prevent accidental extubation. Currently, a cloth glove is usually used with an anti-scratch plate embedded in the palm, which looks similar to an ordinary glove. Then a cloth strip is sewn on the outer surface of the restraint glove to tie the patient's hand to the bed. However, restraining the hand in this way to prevent accidental extubation is not effective. The patient's hand is easy to turn over or scratch inside the glove, and accidental extubation may still occur. Utility Model Content

[0004] In view of the technical problems that the restraining gloves existing in the prior art can still be used by the patient to scratch or turn over, and if the cloth strips are tied too tightly, blood flow will be obstructed, while if they are tied too loosely, they will fall off directly during agitation, resulting in a higher risk of extubation. The utility model provides a restraining device for preventing patients from accidentally extubating.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A restraint device for preventing patients from accidentally removing tubes, comprising a restraint sleeve capable of restraining a palm, a first restraint body detachably connected to one side of the restraint sleeve for restraining a forearm, and a second restraint body detachably connected to one side of the first restraint body for restraining a hind arm, the restraint sleeve being an airbag sleeve, wherein a hand restraint assembly for restraining the movement of the patient's palm is arranged inside the restraint sleeve; the first restraint body comprises a sleeve, two annular airbags respectively arranged on the inner wall of the sleeve opening, a plurality of airbag fixing strips arranged on the inner wall of the sleeve and spaced around the inner circumference of the sleeve, and a hard auxiliary part connected to the outer circumference of the restraint sleeve and adjacent to the two sleeve openings; the structure of the second restraint body is consistent with that of the first restraint body, and the second restraint body is connected to the first restraint body by a hard connector; the outer walls of the restraint sleeve, the first restraint body, and the second restraint body are all provided with fixing belts.

[0007] Furthermore, the hand restraint assembly includes a plurality of soft finger cuffs integrally formed with the restraint sleeve and distributed on the inner wall of the restraint sleeve, and an airbag protrusion arranged below the soft finger cuffs. The plurality of soft finger cuffs are arranged at intervals for inserting fingers therein, and all of the soft finger cuffs are arranged near the head end of the restraint sleeve. When the patient's fingers are inserted into the corresponding soft finger cuffs one by one, the filled airbag protrusion can contact the inner side of the patient's palm.

[0008] Furthermore, a hard connecting ring is fixedly connected to the tail end sleeve position of the restraining soft sleeve, and at least two hard first ears arranged at intervals are provided on the outer periphery of the hard connecting ring, and the connecting end surface of each of the first ears has a first connecting portion, and each sleeve of the first restraining body or the second restraining body is provided with a hard second ear corresponding to the position of the first ear, and a connecting cavity capable of fixing the first connecting portion therein is provided on the second ear.

[0009] Furthermore, the inner wall of the hard connecting ring is provided with a flexible contact layer.

[0010] Furthermore, the outer circumference of the restraint soft sleeve is provided with a plurality of air holes penetrating the restraint soft sleeve.

[0011] Furthermore, the hard connecting member is a telescopic rod with a first connecting portion at both ends, and the first connecting portions at both ends of the telescopic rod are connected to the corresponding connecting cavity.

[0012] Furthermore, all of the airbag fixing strips are arranged along the length direction of the soft cover.

[0013] Furthermore, the soft cover has at least two connection areas, and the outer walls of all the connection areas are fixed with hard gaskets.

The restraining sleeve covers the palm inside, and after the restraining sleeve is filled, the end face is a smooth and arc end face, the fingers are confined in the soft finger sleeve, and the palm position is padded by the raised part of the airbag. The palm in the restraining sleeve cannot scratch arbitrarily, and even if the pipeline is located on one side of the restraining sleeve, there is no condition for grasping and removing the tube. 2. When the first restraining body and the second restraining body fix the limbs, the annular airbag arranged inside the sleeve mouth is used to locate the fixed position of the sleeve, and the airbag fixing strip is arranged along the length of the sleeve and surrounds the arm, which is used to restrict the arm from bending and moving arbitrarily, and further fix the arm. Moreover, after the fixing belt outside the sleeve is tied to the bed, it fixes the entire device and no longer tightly strangles the patient to cause poor blood flow. The patient's limbs are fixed by filling the airbag, and the tightness of the fixation is easy to adjust. 3. After long-term limb restraint, the limbs feel numb and stiff, the drive motor can be started to drive the massage head to massage the patient's limbs, promote blood circulation, and relieve the stiffness of the limbs.

DETAILED DESCRIPTION

[0023] The present invention will be further described below in conjunction with specific drawings.

[0024] See also Figure 1 The utility model provides a restraint device for preventing patients from accidentally removing tubes, comprising a restraint sleeve 100 capable of restraining the palm, a first restraint body 200 detachably connected to one side of the restraint sleeve 100 for restraining the forearm, and a second restraint body 300 detachably connected to one side of the first restraint body 200 for restraining the hind arm. The restraint sleeve 100 is an airbag sleeve, which can be hemispherical or two-thirds spherical after being inflated. A hand restraint assembly for restraining the movement of the patient's palm is provided in the restraint sleeve 100. Please refer to Figure 2The first restraint body 200 includes a soft sleeve 210, two annular airbags 230 respectively arranged on the inner wall of the sleeve opening 220 of the soft sleeve 210, a plurality of airbag fixing strips 240 arranged on the inner wall of the soft sleeve 210 and spaced around the inner circumference of the soft sleeve 210, and a hard auxiliary member 250 connected to the outer circumference of the restraint soft sleeve 100 and adjacent to the two sleeve openings 220. All the airbag fixing strips 240 are arranged along the length direction of the soft sleeve 210. The structure of the second restraint body 300 is consistent with that of the first restraint body 200, and the second restraint body 300 is connected to the first restraint body 200 through a hard connector 500. The outer walls of the restraint soft sleeve 100, the first restraint body 200 and the second restraint body 300 are all provided with a fixing belt 400. When restraining a patient, the hand is restrained and fixed by the hand restraint assembly to prevent it from moving and scratching in the sleeve. After the restraint sleeve 100 is filled, the outer surface and the end of the entire restraint sleeve 100 are relatively smooth, and cannot be firmly contacted with various pipelines, and there is no force application site to pull out the pipeline. Taking the first restraint body 200 as an example, after the hand has been wrapped in the restraint sleeve 100, the first restraint body 200 is continued to be used to put the patient's forearm into the sleeve 210. After the annular airbag 230 is filled, the two ends of the sleeve 210 are fixed to the patient's arm, and the filled airbag fixing strip 240 is fixed to form multiple contact points in the length direction of the arm. The advantage of restraining the patient's arm in this way is that the degree of fixation can be adjusted by gas filling, and the patient's arm will not be tightly strangled to cause poor blood flow. The fixing belt 400 is then used to bind to the bed, which will not hurt the patient's arm, and can be fixed more firmly and will not fall off easily. The annular airbag 230 is used to fix the position of the soft sleeve 210, while the airbag fixing strip 240 is used to limit the arbitrary bending and movement of the arm in the direction of the length of the patient's hand to prevent the overly flexible arm from accidentally touching the pipeline and causing pulling. The first constraint body 200 and the second constraint body 300 can be selected according to the different hand lengths of the patient to choose whether to disassemble and assemble the second constraint body 300 for use. Therefore, the present restraint device restrains the palm and arm, and even if the palm is turned over or scratched in the restraint soft sleeve 100, the surface and end of the restraint soft sleeve 100 are smooth after filling, and the extubation cannot be completed. The method of filling the restraint soft sleeve 100, the annular airbag 230 and the airbag fixing strip 240 will not tightly strangle the patient, but can limit the arm and palm from being flexible. With the reinforcement of the fixing belt 400, the device will not fall off easily, and the patient's activities will be more comprehensively restricted to prevent accidental extubation. The outer ring of the restraint sleeve 100 is provided with a plurality of ventilation holes 140 penetrating the restraint sleeve 100, which can provide ventilation for the hand inside the restraint sleeve 100 to prevent the sweat from breeding bacteria. Moreover, the ventilation holes 140 can also be used as observation holes, which facilitates observation of the internal fixation status when fixing the fingers.

[0025] Please continue reading Figure 1 A rigid connection ring 110 is fixedly connected to the tail end sleeve 220 of the restraining soft sleeve 100. The outer periphery of the rigid connection ring 110 is provided with at least two rigid first ears 111 arranged at intervals. The connecting end surface of each first ear 111 has a first connection part, which can be a screw or a clamping rod with threads on the surface. Each sleeve 220 of the first restraining body 200 or the second restraining body 300 is provided with a rigid second ear 221 corresponding to the position of the first ear 111, and a connecting cavity 2210 is provided on the second ear 221 to fix the first connecting part therein. The first connecting part is screwed or clamped in the connecting cavity 2210, which is easy to assemble.

[0026] The inner wall of the hard connection ring 110 is provided with a flexible contact layer, which can be made of materials such as silicone or sponge pads. When the restraint sleeve 100 is used to restrain the hand, the flexible contact layer can improve the comfort of contact with the patient to avoid wear on the skin.

[0027] See also Figure 3 The hand restraint assembly includes a plurality of soft finger sleeves 120 integrally formed with the restraint sleeve 100 and distributed on the inner wall of the restraint sleeve 100, and an airbag protrusion 130 arranged below the soft finger sleeve 120. The plurality of soft finger sleeves 120 are arranged at intervals for inserting fingers therein. All the soft finger sleeves 120 are arranged near the head end of the restraint sleeve 100. When the patient's fingers are inserted into the corresponding soft finger sleeves 120 one by one, the filled airbag protrusion 130 can contact the inner side of the patient's palm. The soft finger sleeve 120 is made of elastic soft belt and can be used to fit fingers of different fatness and thinness. When the airbag protrusion 130 is filled, it is actually cushioned at the center of the patient's palm, and the palm restrained in the restraint sleeve 100 is fixed. After a spherical component is placed in the center of the palm, the palm is basically fully restricted to prevent scratching inside and damaging the restraint glove.

[0028] The soft cover 210 has at least two connection areas 260, and the outer walls of all the connection areas 260 are fixed with hard gaskets (not shown in the figure), and the hard auxiliary component 250 is connected to the hard gasket by bolts. Figure 4 Each of the hard auxiliary parts 250 is equipped with a massage component. The outer wall of the hard auxiliary part 250 is provided with a control switch 270 for controlling the start or stop of the massage component. One side of the control switch 270 is provided with a gas injection terminal 280 for connecting the gas source to deliver gas to each component that needs gas injection. During the long-term restraint process, the patient's limbs will inevitably feel stiff. The massage component is activated by the control switch 270 to massage the arm to relieve the fatigue of the restraint.

[0029] The massage assembly includes a driving unit 600 disposed in the hard auxiliary part 250 and detachably connected to the hard auxiliary part 250, a massage head 700 connected to the driving unit 600, a through hole penetrating the connection area 260, and a mounting member 800 fixed in the through hole, the first end face of which is flush with the inner surface of the connection area 260 and is hollow inside, and the second end face of the mounting member 800 protrudes toward the outside of the through hole. The hollow inner cavity of the mounting member 800 is defined as a mounting cavity, and the driving unit 600 drives the massage head 700 to reciprocate along the mounting cavity, and the moving massage head 700 can extend out of the mounting cavity to contact the patient. When the airbag fixing strip 240 is filled, the end of the massage head 700 is away from the contact surface of the airbag fixing strip 240 that contacts the patient. When restraining and fixing, the massage head 700 does not contact the limbs, and relies on the airbag fixing strip 240 to contact the patient's arm for fixing, so the massage head 700 protruding from the installation cavity toward the inner wall of the connection area 260 will not interfere with the fixation of the limbs. When the massage component needs to be used for massage, the airbag fixing strip 240 is deflated and shrunk, so that the massage head 700 can contact the patient's limbs for massage.

[0030] See also Figure 5 The driving unit 600 includes a driving motor 610 screwed to the hard auxiliary part 250, a second connecting part 620 connected to the driving motor 610, a connecting shaft 630 connected to the second connecting part 620 at one end, and a third connecting part 640 connected to the connecting shaft 630 through a bearing, and the other opposite end of the third connecting part 640 is connected to the massage head 700 through a bearing. The massage head 700 includes a massage column 710 and a massage end head 720 screwed to the massage column 710, a shock absorbing spring 712 is connected to one end of the massage column 710, and the shock absorbing spring 712 is connected to a fourth connecting part 711, and the fourth connecting part 711 is connected to the third connecting part 640. The driving motor 610 is a small or micro motor used for massage to reduce the patient's weight. Moreover, after the massage component is assembled in the hard auxiliary part 250, it will also play a role in limiting the arbitrary bending of the limbs. If the massage assembly is not needed, the hard auxiliary member 250 can be removed from the connection area 260, and the massage assembly is also removed, but the restraining and fixing ability is not affected. When the drive motor 610 is started to drive the massage head 700 to massage the arm, the shock absorbing spring 712 can buffer the impact force and reduce the discomfort of the patient's massage impact.

[0031] The hard connector 500 is a telescopic rod with a first connecting portion at both ends, and the first connecting portions at both ends of the telescopic rod are connected to the corresponding connecting cavity 2210. The first constraint body 200 and the second constraint body 300 can be used alternately, reducing the manufacturing cost and the difficulty of assembly connected to the constraint soft sleeve 100. The telescopic rod can adjust the length, that is, the length of the first constraint body 200 and the second constraint body 300 to fix the patient can be adjusted to adapt to more arms of different lengths, and the adjustment is flexible and practical. Moreover, the hard connector 500 is connected between the two constraint bodies, and both have the function of limiting the bending movement of the patient's arm with the hard auxiliary member 250. The limitation of the hard connector 500 is more that after the front and rear arms are fixed, it is used to limit the elbow joint position from bending and moving, and the hard auxiliary member 250 is installed on the soft sleeve 210. Even if the airbag fixing strip 240 is not filled or damaged, there is still the limitation of the hard auxiliary member 250, which can also limit the patient's arm from arbitrarily moving and performing unplanned extubation.

[0032] This restraint device, first, the restraint sleeve 100 puts the palm inside, and after the restraint sleeve 100 is filled, the end face is a smooth and arc end face, the fingers are restricted in the soft finger sleeve 120, and the airbag protrusion 130 is cushioned at the palm position. The palm inside the restraint sleeve 100 cannot scratch arbitrarily, and even if the pipeline is located on one side of the restraint sleeve 100, there is no condition for grasping and removing the tube. Second, when the first restraint body 200 and the second restraint body 300 fix the limb, the annular airbag 230 set inside the sleeve 220 of the soft sleeve 210 is used to locate the fixed position of the soft sleeve 210, and the airbag fixing strip 240 is arranged along the length of the soft sleeve 210 and surrounds the arm, which is used to restrict the arm from bending and moving arbitrarily, and further fix the arm. Moreover, the fixing belt 400 outside the soft sleeve 210 is used to fix the entire device after being tied to the bed, and no longer tightly strangles the patient to cause poor blood flow. The patient's limbs are fixed by filling the airbag, and the degree of tightness of the fixation is easy to adjust. 3. After long-term restraint of the limbs, the limbs feel numb and stiff, and the drive motor 610 can be started to drive the massage head 700 to massage the patient's limbs, promote blood circulation, and relieve the stiffness of the limbs.
