Description

Finger exerciser after radial artery coronary angiography or stent intervention operation

Technical Field

The invention belongs to the field of clinical rehabilitation tools, and particularly relates to a finger exerciser after radial coronary angiography or stent intervention.

Background

The development of coronary angiography and stent surgery is more and more mature, the surgery also needs femoral artery puncture on the thigh of a patient from the beginning to the operation mode that most patients can be operated through radial artery puncture on the wrist at present, so that the patients can recover faster, have smaller wounds, do not need to lie in bed for a long time, and gradually develop into a preferred surgery mode. Although the operation wound is small, the artery vessel is punctured, the intravascular pressure is high, and if the treatment is not good, a tragic field of three feet blood splashing can occur, so that a pressurizing hemostasis device is required to be used for 24 hours after the operation to press the puncture point of the radial artery to stop bleeding. The long-time compression hemostasis can cause the local limb blood and lymph reflux to be blocked, so that the limb of the patient feels discomfort such as swelling, numbness, pain, bruise and the like, and the discomfort of the patient is increased. Postoperative clinical observation shows that: local movement of the hand at an early stage may alleviate the above symptoms to some extent, so that the patient should perform hand movement as soon as possible after the operation. At present, the conventional finger motion exercise is recommended to start before 1 day and a nurse learns, the patient starts to exercise after returning to a ward, and the exercise is recommended to be performed once per hour under the waking state until the pressurizing device is released. Obviously, because the exercise is an active exercise mode, the actual exercise process and results are difficult to reach ideal standards due to the age, education degree difference and even character difference of patients during actual operation, and a solution is urgently needed.

In order to achieve the purpose, the invention adopts the following technical scheme:

a finger portion exerciser after radial coronary angiography or stent intervention is characterized in that: the finger exerciser comprises a pressing plate, wherein torsion spring support seats are arranged at the middle plate body of the pressing plate so as to be combined together to form a seesaw structure; under the action of the elastic restoring force of the torsional spring support, the height of the head end of the pressing plate is lower than that of the tail end; the tail end plate of the pressing plate forms a contact end for placing the finger of the patient, a cam driven by a power source is arranged below the head end plate body of the pressing plate, the axis of the cam is parallel to the axis of the support, and a contact matching relation is formed between the rim of the cam and the lower plate surface of the head end of the pressing plate, so that the pressing plate is driven to generate seesaw type reciprocating tilting motion under the reciprocating action of the rotation motion of the cam and the elastic restoring force of the torsion spring support.

Preferably, the pressing plates are five groups so as to correspond to five fingers of the human body one by one; five groups of pressing plates are arranged on the bottom plate in a piano type; a group of cams are respectively arranged below the head end plate bodies of the five groups of pressing plates, the five groups of cams are uniformly distributed on a rotating shaft and are driven by a power motor serving as a power source to generate rotating action; the rotating shaft is in a simple beam shape and is coaxially matched with the bearing seat at the end part in a rotating way.

Preferably, the end bearing block comprises a first bearing block relatively close to the power motor and a second bearing block relatively far away from the power motor; a T-shaped groove with a narrow opening and a wide bottom is arranged on the bottom plate along the axial length direction of the rotating shaft; a T-shaped guide block matched with the cross section profile of the T-shaped groove is arranged at the bottom of the second bearing seat, the T-shaped guide block is clamped into the T-shaped groove, and the vertical screws sequentially penetrate through the T-shaped groove from top to bottom and are in threaded fit with the notch of the T-shaped groove and the T-shaped guide block; the rotating shaft comprises an end shaft section which is in rotating fit with the end bearing seat and a matching shaft section for mounting the cam, and the end shaft section and the adjacent end of the matching shaft section form a rotation stopping type inserting fit which can be axially inserted.

Preferably, the end shaft section is coaxially and convexly provided with a quadrangular prism, and the corresponding end face of the matching shaft section is coaxially and concavely provided with a quadrangular hole matched with the quadrangular prism in shape.

The invention has the beneficial effects that:

1) The hand action mode of usefulness of restoreing after the operation is diversified, only need can alleviate the corresponding uncomfortable situation of patient's postoperative can. For the invention, the structure of the seesaw is ingeniously utilized: on the one hand, come both to support as the fulcrum through the torsional spring support and press the board, can make again to press the board to have the trend of "head-to-tail low" all the time. On the other hand, the existence of the cam driven by the power source can continuously push the tail end of the pressing plate through the rotation action of the cam, so that the pressing plate has the action trend of 'tail high and hand low'. Therefore, the torsion spring support and the cam are mutually cooperated, the pressing plate can be continuously driven to generate seesaw movement, the fingers of a patient placed at the head end of the pressing plate can generate follow-up movement, and the passive exercise function is realized.

In conclusion, the invention has the advantages of simple structure, simple and quick operation and low cost, can replace the currently adopted active exercise mode, not only ensures the necessary exercise time, but also has higher use convenience and easy acceptance by patients, can effectively relieve the discomfort conditions of swelling, numbness, pain, bruise and the like of the limbs of the patients, promotes the rapid rehabilitation of the motion function of the limbs on the puncture side, and is beneficial to clinical use.

2) As a further preferable aspect of the above aspect, in consideration of the fact that the patient performs exercise with better exercise effect by the action of all five fingers, the present invention arranges five groups of pressing plates in a key shape. When the device works, the cam and the rotating shaft form a structure similar to a crankshaft, so that five groups of pressing plates are driven to generate synchronous or sequential or disordered finger pressing actions similar to keys. The difference lies in that people press the keys actively, but the invention drives the fingers of the patient to do reciprocating pressing exercise with follow-up action, and the effect is remarkable.

3) For different patients, the finger length and the finger thickness are different, and the reciprocating pressing depth of the fingers can be different; thus, the mating shaft segment with the cam of the present invention is replaceable. In other words, a cam of a matching size can be appropriately replaced for a particular patient or a particular amount of movement; at the moment, after the plumb screw is screwed off, the second bearing seat is pulled open, the matched shaft section is axially disassembled and replaced, then the second bearing seat is reset, the two end shaft sections and the replaced matched shaft section form the whole rotating shaft again, and finally the plumb screw is fixed again. The replacement action is simple and convenient, the operability is strong, and the practical use is facilitated.

4) Specifically, the matching conditions that must be satisfied between the end shaft section and the matching shaft section are: the axial direction can be separated, and the circumferential direction can be stopped rotating. Therefore, the end shaft section and the matching shaft section can be matched in an axial insertion mode of a quadrangular prism and a quadrangular hole, or in a mode of a rotation stopping pin, or even in a mode of inserting a plurality of axial pins to realize rotation stopping matching, and the like, as referred to in the invention, and the description is omitted here.

5) The shelf is arranged to elevate the palm of the patient so that the patient can perform finger following actions in a posture that is easier to exercise. If necessary, the shelf can be arranged with a dressing surface, thereby realizing synchronous thermal therapy and even cold compress rehabilitation effect. The bottom plate can even be directly integrated with a rechargeable power supply, so that the off-line use function of the invention can be realized.

6) The finger stall is used for fixing the fingers of the patient, so that the fingers of the patient are prevented from being accidentally separated from the finger stall. The function of the restraining strip is to further enhance the fixing effect. The restraint strap can adopt a conventional tying strap, and can also adopt a fixing mode such as a magic tape and the like so as to take the fixing effect as the standard.

Detailed Description

For the purposes of understanding, the invention will be further described in its specific structure and mode of operation with reference to the accompanying drawings in which:

the detailed structure of the present invention is shown with reference to fig. 1-4, and the main structure thereof comprises three blocks, namely an exercise component, a power component and a power supply component, which are all integrated on a bottom plate 40. Wherein:

the exercise member includes five groups of pressing plates 10 arranged in a key shape. As can be seen from fig. 1-2, the head end of each pressing plate 10, i.e. the right end shown in fig. 2, forms a contact end, and the finger stall 11 and the restraining band 12 are disposed to fix the corresponding finger of the patient. The cam 30 is disposed at the rear end of each set of the pressing plates 10, i.e., just below the left end as viewed in fig. 2, so that the cam 30 is operated by the rotational movement of the rotating shaft 50, thereby performing the reciprocating seesaw type operation of the pressing plates 10 along the torsion spring support 20. Thus, on one hand, the torsion spring support 20 is used as a fulcrum to support the middle plate body of the pressing plate 10, and the pressing plate 10 always tends to be high in the head and low in the tail. On the other hand, the tail end of the pressing plate 10 is continuously pushed by the rotation of the cam 30, so that the pressing plate 10 has a motion trend of 'tail high and hand low'; the torsion spring support 20 and the cam 30 cooperate with each other to continuously generate a seesaw motion of the pressing plate 10, which causes the fingers of the patient fixed in the finger sleeve 11 to follow the seesaw motion, thereby realizing the passive exercise function.

Below the five groups of the pressing plates 10 arranged in a key shape as shown in fig. 1, a shelf 90 having a facing 91 is further provided. The shelf 90 on the one hand functions to lift the palm of the patient to facilitate the movement of the patient's fingers; on the other hand, the face 91 has the function of hot compress or cold compress, so as to synchronously promote the blood circulation of the palm face and relieve the discomfort conditions of swelling, numbness, pain, bruise and the like on the palm face of the patient after the finger exercises, thereby achieving multiple purposes.

The power unit includes a power motor 60 and a rotating shaft 50 driven by the power motor 60. The rotation shaft 50 is rotatably fitted to the first bearing housing 71 and the second bearing housing 72 in a simple beam shape, so that the cam 30 provided on the rotation shaft 50 is driven to follow by the rotation of the rotation shaft 50. The swivel shaft 50 is formed in a three-piece assembled structure as shown in fig. 3, i.e., an end shaft section 51 at both ends and a mating shaft section 52 at the middle section. During operation, the second bearing seat 72 is slid open only by screwing off the vertical screw 80 and relying on the guiding relationship between the T-shaped groove 41 and the T-shaped guide block 72 a. At this time, the second bearing housing 72 is axially moved apart from the first bearing housing 71 with an increased distance therebetween to facilitate axial removal and replacement of the mating shaft segment 52. After the mating shaft segment 52 is replaced, the second bearing seat 72 is reset, so that the two end shaft segments 51 and the replaced mating shaft segment 52 can be inserted into the quadrangular prism 51a and the quadrangular prism hole 52a again to form the whole revolving shaft 50 as shown in fig. 3. Finally, the plumb screw 80 is screwed down again, so that the purpose of online dismounting can be conveniently realized.

As far as the power supply means are concerned, they are integrated in the base plate 40, so that an electrically driving effect on the application surface 91 and the power motor 60 is achieved. The power supply part is a chargeable and dischargeable power supply 100, so that the offline action of the invention without external power is realized, and the application range of the invention is improved.
