Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a multifunctional grip strengthener for patients with PICC line insertion. Background Technology

[0002] Peripherally inserted central catheter (PICC) involves inserting a catheter into a vein in the arm and then directly into a large vein near the heart. This avoids direct contact between chemotherapy drugs and the veins in the arm. In addition, the high blood flow in the large vein can quickly dilute the chemotherapy drugs and prevent them from irritating the blood vessels.

[0003] While PICC line placement provides patients with a convenient intravenous access, long-term placement may restrict upper limb movement, leading to varying degrees of muscle atrophy and potentially affecting blood circulation, thus increasing the risk of thrombosis. To reduce the adverse effects of PICC line placement on upper limb function and promote patient recovery, targeted rehabilitation exercises are necessary. Hand grip strengtheners are simple and convenient to use, effectively exercising upper limb muscles, enhancing muscle strength, and promoting blood circulation through grip training, thereby reducing the risk of thrombosis and helping patients better recover upper limb function.

[0004] In the existing technology, the existing hand grip strengthener has a simple structure and single function, which can only exercise the palm and forearm; and patients cannot know whether the grip strength generated each time they hold the hand grip strengthener meets the standard required for exercise, which can easily lead to over-exercise and physical injury. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a multifunctional hand gripper for patients with PICC catheterization, which can effectively solve the shortcomings of the prior art.

[0006] A multifunctional grip strengthener for patients with PICC line insertion includes two spherical pressure structures and a grip assembly disposed on the outer surface of the pressure structures. A pressure sensor for sensing grip force is disposed within each pressure structure. The grip assembly includes a palm pressure portion disposed at the top of the center of the pressure structure and a finger grip portion disposed on one side of the palm pressure portion. Multiple abutment portions for separating fingers are equally spaced on the outer surface of the pressure structure corresponding to the finger grip portions. The finger grip portion includes a four-finger structure and a thumb structure. A sensor light structure electrically connected to the pressure sensor for indication is also disposed at the finger gaps of the four-finger structure. A pressure display electrically connected to the pressure sensor is also disposed on the outer surface of the pressure structure. The pressure display is disposed on the side of the center of the pressure structure away from the palm pressure portion. A button for adjusting the pressure displayed on the pressure display is disposed on the side of the pressure display away from the finger grip portion.

[0007] Furthermore, a number of connectors are provided on the outer surface of the pressure structure, and the connectors are symmetrically arranged on both sides of the pressure display.

[0008] Furthermore, a plurality of tension rope structures are connected between the two pressure structures, with each end of the tension rope structure being connected to a connecting member of the two pressure structures respectively.

[0009] Furthermore, the grip portion is concave in an arc shape toward the center of the pressure structure.

[0010] Furthermore, anti-slip pads are provided on both the grip portion and the palm pressure portion.

[0011] Furthermore, the pressure structure is made of silicone or rubber material.

[0012] Furthermore, the abutment portion is in the shape of an inverted frustum or an inverted truncated pyramid.

[0013] Furthermore, the sensor light structure is an LED light.

[0014] The beneficial effects of this utility model are as follows: After the user adjusts the pressure displayed on the pressure display to the required pressure for exercise using the button, they place their palm on the palm pressure part and their fingers on the finger grip part. By continuously pressing the palm pressure part and the finger grip part, the force generated by the pressing is continuously transmitted to the pressure sensor inside the pressure structure. When the force generated by the pressing reaches the pressure displayed on the pressure display, the sensor light illuminates to indicate to the user that the pressing has reached the required standard for exercise. The user can then release the force and proceed to the next exercise. This allows the user to know whether the grip force generated each time they hold this utility model meets the required standard for exercise, thus avoiding over-exercising and potential physical injury.

[0024] Please see Figures 1 to 3 The multifunctional gripper for PICC placement patients in this embodiment includes two spherical pressure structures 10 and a gripping assembly disposed on the outer surface of the pressure structures 10. A pressure sensor 21 for sensing gripping force is disposed within the pressure structure 10. The gripping assembly includes a palm pressure part 11 disposed at the top of the center of the pressure structure 10 and a finger grip part disposed on one side of the palm pressure part 11. A plurality of abutment parts 14 for separating fingers are disposed at equal intervals on the outer surface of the pressure structure 10 corresponding to the finger grip part. The finger grip part includes a four-finger structure 12 and a thumb structure 13. A sensor light structure 15 electrically connected to the pressure sensor 21 for prompting is also disposed at the finger gaps of the four-finger structure 12. A pressure display 16 electrically connected to the pressure sensor 21 is also disposed on the outer surface of the pressure structure 10. The pressure display 16 is disposed on the side of the center of the ball away from the palm pressure part 11. A button 17 for adjusting the pressure displayed on the pressure display 16 is disposed on the side of the pressure display 16 away from the finger grip part.

[0025] Understandably, after adjusting the pressure displayed on the pressure display 16 to the required pressure for exercise using the button 17, the user places their palm on the palm pressure part 11 and their fingers on the finger grip part. By continuously pressing the palm pressure part 11 and the finger grip part, the force generated by the pressing is continuously transmitted through the palm pressure part 11 and the finger grip part to the pressure sensor 21 in the pressure structure 10. When the force generated by the pressing reaches the pressure displayed on the pressure display 16, the sensor light structure 15 lights up to indicate to the user that the pressing has reached the required standard for exercise, and the user can release the force and proceed to the next exercise. This allows the user to know whether the grip force generated each time they hold the device has reached the required standard for exercise, avoiding over-exercising and potential physical injury.

[0026] Furthermore, a plurality of connectors 18 are provided on the outer surface of the pressure structure 10, and the connectors 18 are symmetrically arranged on both sides of the pressure display 16.

[0027] Furthermore, a plurality of tension rope structures 19 are connected between the two pressure structures 10, and the two ends of the tension rope structures 19 are respectively connected to the connectors 18 of the two pressure structures 10.

[0028] Understandably, by setting up the connector 18 and the tension rope structure 19, the user places both hands on the palm pressure part 11 of the two pressure structures 10 respectively, while placing the fingers on the finger grip part. By continuously opening and closing the arms, the user can exercise the muscles of multiple parts of the whole body through this utility model, including the biceps and triceps of the arms, the latissimus dorsi of the back, the pectoral muscles of the chest, and the muscles of the legs, thereby increasing the functionality of this utility model.

[0029] Furthermore, the grip portion is concave in an arc shape toward the center of the pressure structure 10.

[0030] Understandably, by making the grip portion concave in an arc shape toward the center of the pressure structure 10, the grip portion can fit the user's fingers more closely, making it easier for the user to exercise.

[0031] Furthermore, anti-slip pads 20 are provided on both the grip portion and the palm pressure portion 11.

[0032] It is understandable that by providing anti-slip pads 20 on both the grip portion and the palm pressure portion 11, this utility model is designed to prevent the operator's hands from slipping due to sweat during exercise.

[0033] Furthermore, the pressure structure 10 is made of silicone or rubber.

[0034] Furthermore, the abutment portion 14 is in the shape of an inverted frustum or an inverted truncated pyramid.

[0035] Understandably, by setting the abutment part 14 in the shape of an inverted frustum or an inverted pyramid, the user's fingers are prevented from slipping out of the grip during exercise. Furthermore, by setting the abutment part 14, the operator can clamp the abutment part 14 with their fingers when performing finger opening and closing exercises, thereby providing a massage effect on the fingers.

[0036] Furthermore, the sensor light structure 15 is an LED light.

[0037] In summary, the multifunctional hand gripper for PICC line insertion patients described in the above embodiments of this utility model allows the user to adjust the pressure displayed on the pressure display to the required level using a button. The user then places their palm on the palm pressure section and their fingers on the finger grip section. By continuously pressing the palm pressure section and finger grip section, the force generated is continuously transmitted through these sections to the pressure sensor within the pressure structure. When the force reaches the level displayed on the pressure display, the sensor light illuminates to indicate that the pressure has reached the required level for the exercise. The user can then release the pressure and begin the next exercise. This allows the user to know whether the grip strength generated each time they hold the device meets the required level, preventing over-exercising and potential injury.
