Description

Technical Field

[0001] The utility model relates to the field of medical appliances, in particular to a palm spreading device for elderly patients with limited extensor metacarpophalangeal joints. Background Art

[0002] Dupuytren's contracture, also known as Viking hand or Dupuytren's contracture, is a connective tissue disorder of the hand that causes thickening and shortening of fibrous tissue bands and skin, resulting in long-term bending of the fingers. The little finger and ring finger are most affected.

[0003] Elderly patients have limited finger movement, usually due to Dupuytren's contracture. The patient's fingers will bend inward toward the palm. Long-term pressure on the palm can easily cause pressure injuries. The condition will worsen over time, and it will become increasingly difficult for the patient to straighten his fingers.

[0004] Therefore, how to design a distraction device that can assist patients in extending their finger joints has become an urgent problem to be solved in the field of medical devices. Utility Model Content

[0005] The purpose of the utility model is to provide a palm stretching device for elderly patients with limited extensor metacarpophalangeal joints. The device stretches the patient's palm by holding the ball balloon, so that the patient's finger joints are stretched, avoiding pressure injuries caused by the fingers of patients with limited finger joints being pressed inward on the palm for a long time.

[0006] In order to achieve the above-mentioned purpose of the invention, the present invention adopts the following technical solutions:

[0007] A palm stretching device for elderly patients with limited extensor metacarpophalangeal joints comprises a grip ball and a glove. The grip ball outer shell is provided with a balloon for stretching the palm, and the outer surface of the balloon is provided with four finger hair stickers. The index finger, middle finger, ring finger and little finger of the glove are respectively provided with finger hook stickers. The patient's palm can wear the glove and the four fingers are respectively grasped on the four finger hair stickers on the outer surface of the grip ball balloon. The four finger hair stickers are respectively fixed to the four finger hook stickers by Velcro. An air supply tube for inflating and deflating the balloon is also provided outside the balloon: when the air supply tube injects air into the balloon, the volume of the balloon increases and stretches the patient's palm, thereby stretching the finger joints.

[0008] Compared with the existing technology, the palm spreading device for elderly patients with limited extensor metacarpophalangeal joints using the above technical solution has the following beneficial effects:

[0009] With the palm stretching device of the utility model for elderly patients with limited extensor metacarpophalangeal joints, medical staff put gloves on the patient's palm, then place the four finger hooks on the four finger hair stickers of the balloon respectively and fix them with Velcro, so that the patient can hold the ball with his palm, and then inject air into the balloon through the air tube. The volume of the balloon will gradually increase and stretch the palm, so that the patient's finger joints can be stretched, avoiding pressure injuries caused by the fingers of patients with limited finger joints being pressed inward on the palm for a long time.

[0010] Preferably, there are gaps between the finger hair stickers, so that the four fingers can be separated to hold the ball. The balloon is repeatedly inflated and deflated through the air tube, so that the patient's palm repeatedly opens and retracts to perform therapeutic training. The patient's fingers are kept separated during the balloon volume change, which has a better therapeutic training effect.

[0011] Preferably, the grip surface is provided with four recesses, which are respectively provided at positions corresponding to the four finger hair stickers. The finger hair stickers are sunken into the recesses, and the four recesses respectively position four fingers. When the medical staff puts the patient's fingers into the recesses, the finger hair stickers can be aligned and connected with the finger hook stickers, which is easy to operate.

[0012] Preferably, the air delivery pipe is connected to an air pump controller, and the air pump controller can refer to the existing Huiduoduo electric air pump. The air pump controller not only controls the inflation and deflation of the balloon, but also adjusts the inflation speed according to demand and displays the value.

[0013] Preferably, the grip ball is provided with a handle, the end of which is fixed to the center of the grip ball. When the patient holds the grip ball in his palm, the handle is placed between the index finger and thumb. The medical staff holding the handle makes it easier to insert the grip ball into the patient's hand and prevents the grip ball from accidentally rolling in the patient's hand.

[0014] Preferably, there are two grip balls, which are respectively arranged at the two ends of the handle. The patient holds the two grip balls with both hands, which can stretch the patient's finger joints at the same time.

[0015] Preferably, a three-way valve is provided at the midpoint of the ball handle. The three-way valve includes a main valve tube and two auxiliary valve tubes. The two auxiliary valve tubes are respectively connected to the two ball-holding balloon cavities. The air supply tube is connected to the main valve tube. A rotatable valve core is provided in the three-way valve. The valve core is provided with a T-shaped channel. The channel rotates the valve core so that the main valve tube is connected to the two auxiliary valve tubes through the T-shaped channel, or the main valve tube is connected to one of the auxiliary valve tubes through the T-shaped channel, or the main valve tube is connected to the other auxiliary valve tube through the T-shaped channel. The air pump controller can simultaneously inflate and deflate the two ball-holding balloons through the three-way valve to provide therapeutic training for both patients at the same time, or it can unidirectionally inflate and deflate one ball-holding balloon to provide therapeutic training for a single hand of the patient.

[0016] Preferably, the outer surface of the ball balloon is further provided with a palm hair sticker, and the palm of the glove is provided with a palm hook sticker. The patient's palm is grasped on the palm hair sticker on the outer surface of the ball balloon, and the palm hook sticker and the palm hair sticker are fixed with Velcro. This strengthens the fixation of the patient's palm, prevents the patient's palm from leaving the ball, and improves the therapeutic training effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0027] Example 1

[0028] like Figures 1 to 4The palm stretching device for elderly patients with limited extensor metacarpophalangeal joints shown in the figure includes a grip ball 1 and a glove 3. The grip ball 1 is provided with a balloon 2 for stretching the palm, and the outer surface of the balloon 2 is provided with four finger hair stickers 21. The glove 3 is provided with finger hook stickers 31 on the index finger, middle finger, ring finger and little finger. The patient's palm can wear the glove 3 and the four fingers are respectively grasped on the four finger hair stickers 21 on the outer surface of the balloon 2 of the grip ball 1. The four finger hair stickers 21 are respectively fixed to the four finger hook stickers 31 by Velcro. An air supply tube 42 for inflating and deflating air into the balloon 2 is also provided outside the balloon 2: when the air supply tube 42 injects air into the balloon 2, the volume of the balloon 2 increases and stretches the patient's palm, so that the finger joints are stretched. The medical staff puts the glove 3 on the patient's palm, then places the four-finger hook stickers 31 on the four finger hair stickers 21 of the balloon 2 and fixes them with Velcro, so that the patient's palm holds the grip ball 1, and then injects air into the balloon 2 through the air supply tube 42. The volume of the balloon 2 will gradually increase and stretch the palm, so that the patient's knuckles can be stretched, avoiding pressure injuries caused by the patient's fingers being restricted and pressed inward on the palm for a long time.

[0029] There are gaps between the finger hair stickers 21, allowing the four fingers to separate and grasp the grip ball 1. The balloon 2 is repeatedly inflated and deflated through the air supply tube 42, causing the patient's palm to repeatedly open and retract for therapeutic training. The patient's fingers are kept separate during the volume change of the balloon 2, which results in a better therapeutic training effect.

[0030] Reference Figures 1 to 3 The surface of the grip ball 1 is provided with four embedding grooves 11, which are respectively arranged at the corresponding positions of the four finger hair stickers 21. The finger hair stickers 21 are sunken into the embedding grooves 11, and the four embedding grooves 11 respectively position four fingers. When the medical staff puts the patient's fingers into the embedding grooves 11, the finger hair stickers 21 can be aligned and connected with the finger hook stickers 31, which is easy to operate.

[0031] The air delivery pipe 42 is connected to an air pump controller, which can be a reference to an existing Huiduoduo electric air pump. The air pump controller not only controls the inflation and deflation of the balloon 2, but also adjusts the inflation speed and displays the value according to demand.

[0032] The grip ball 1 is provided with a handle 12, the end of which is fixed to the center of the grip ball 1. When the patient grasps the grip ball 1, the handle 12 is positioned between the index finger and thumb. The medical staff holding the grip ball 1 by the handle makes it easier to insert the grip ball 1 into the patient's hand and prevents the grip ball 1 from rolling accidentally in the patient's hand.

[0033] Reference Figure 4 The outer surface of the glove 3 is provided with a buckle 34 at the cuff, and a strap 33 is wrapped around the cuff. The strap 33 passes through the buckle 34 and is secured with Velcro. The buckle 34 positions the strap 33, preventing it from falling out of the cuff. The strap 33 also tightens the cuff of the glove 3 and strengthens the fixation between the glove 3 and the patient's wrist, making it suitable for patients of different wrist sizes.

[0034] Example 2

[0035] like Figures 5 to 8 The palm spreading device for elderly patients with limited extensor metacarpophalangeal joints is shown. This embodiment is based on embodiment 1. The difference between this embodiment and embodiment 1 is that the number of grip balls 1 on the handle 12 is different.

[0036] Reference Figure 5 and Figure 6 The number of grip balls 1 is two, and the two grip balls 1 are respectively arranged at both ends of the ball handle 12. The patient holds the two grip balls 1 with both hands, and the patient's finger joints can be stretched at the same time.

[0037] A three-way valve 5 is installed at the midpoint of the handle 12. The valve comprises a main valve tube 51 and two auxiliary valve tubes 52, each connected to the cavities of the two gripping ball 1 balloons 2. The air supply tube 42 is connected to the main valve tube 51. A rotatable valve core 53 is located within the three-way valve 5, which contains a T-shaped channel 54. Rotating the valve core 53 allows the main valve tube 51 to connect to each of the two auxiliary valve tubes 52 through the T-shaped channel 54 (as shown in Figure a), or to connect to one of the auxiliary valve tubes 52 through the T-shaped channel 54 (as shown in Figure b), or to connect to the other auxiliary valve tube 52 through the T-shaped channel 54 (as shown in Figure c). The air pump controller, through the three-way valve 5, can simultaneously inflate and deflate both gripping ball 1 balloons 2, providing therapeutic training for both patients. Alternatively, it can unidirectionally inflate and deflate one gripping ball 1 balloon 2, providing therapeutic training for a single hand.

[0038] The valve core 53 is equipped with a knob 55 on the outside of the three-way valve 5. Turning the knob 55 rotates the valve core 53 within the three-way valve 5. This is similar to a conventional medical three-way stopcock valve (manufactured by Suzhou Haners Plastic Products Co., Ltd.). Medical personnel can determine the current flow status of the three-way valve 5 by the direction of the knob 55, making operation convenient.

[0039] Reference Figure 7 and Figure 8 The outer surface of the ball ball 2 is also provided with a palm hair sticker 22, and the palm of the glove 3 is provided with a palm hook sticker 32. The patient's palm is grasped on the palm hair sticker 22 on the outer surface of the ball ball 1. The palm hook sticker 32 and the palm hair sticker 22 are fixed with Velcro. This strengthens the fixation of the patient's palm, prevents the patient's palm from leaving the ball ball 1, and improves the therapeutic training effect.
