Description

Technical Field

[0001] This invention belongs to the field of medical assistive device technology, specifically a PICC placement exercise glove. Background Technology

[0002] Peripherally inserted central catheter (PICC) is a deep vein catheterization technique that inserts a catheter into the superior vena cava through peripheral veins such as the basilic vein or the median cubital vein. By rapidly diluting the medication through the central venous blood flow, chemotherapy drugs can avoid direct stimulation of peripheral blood vessels, effectively protecting the veins of the upper limb, reducing the occurrence of phlebitis, alleviating patient pain, and improving quality of life.

[0003] Catheter-related thrombosis (CRT) refers to thrombi that form on the inner wall of blood vessels or catheters due to mechanical damage caused by catheter puncture, chemical damage caused by drug irritation, or other patient-related factors. Studies indicate that the incidence of CRT is high in patients with PICC lines, with symptomatic thrombosis occurring in 2%–15% of cases and asymptomatic thrombosis in 2.2%–58.0%. The incidence is even higher in patients undergoing chemotherapy for cancer, those on prolonged bed rest, and those in a hypercoagulable state. CRT can impair catheter function and delay treatment, and thrombus detachment can lead to embolism in vital organs and even endanger the patient's life.

[0004] Currently, grip ball exercises are commonly used in clinical practice to enhance the afterload of upper arm muscle contraction, promote blood circulation and lymphatic return, improve local microcirculation, and thus reduce the risk of catheter-related thrombosis. It is simple and safe to operate and is a common upper limb function exercise method for PICC patients. However, the grip ball has a simple structure, and patients are prone to losing or displacing the grip ball during activities, which affects the continuity of exercise. At the same time, there is no mechanical linkage reminder structure, so it is impossible to trigger intuitive prompts through the gripping action, which affects the patient's exercise compliance and makes it difficult to guarantee the exercise effect.

[0005] Therefore, a PICC placement exercise glove is proposed to address the above problems. Summary of the Invention

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The following describes an embodiment of this utility model based on its overall structure.

[0024] like Figures 1 to 4As shown, the present invention provides a PICC placement exercise glove, including a glove body 1, a grip component 2 at the bottom of the glove body 1, a grip groove 201 at the bottom of the glove body 1, an installation frame 202 fixedly provided on the outer side of the bottom of the grip groove 201, and a spring sheet 203 slidably provided inside the grip groove 201 to provide basic elastic grip force, meet the needs of patients with mild hand grip force rehabilitation exercises, and avoid muscle atrophy of the limb on the placement side. An installation block 204 is fixedly provided on the outer side of the bottom of the spring sheet 203, and an installation slot 205 is provided at the bottom of the installation frame 202. The installation block 204 engages with the installation slot 205, so that the spring sheet 203 can be detached and replaced, and can be adapted to spring sheets 203 with different elastic strengths to meet the exercise intensity needs of patients at different rehabilitation stages.

[0025] In a further embodiment, the bottom of the mounting frame 202 is threadedly fitted with a grip ball 206, and the inside of the grip ball 206 is provided with a mounting groove 207. A battery 208 is fixedly mounted on the front side of the mounting groove 207 to provide a stable power supply foundation for subsequent electronic components.

[0026] A vibration motor 209 is fixedly installed on the front side of the inside of the grip ball 206. The vibration motor 209 is electrically connected to the battery 208 to guide the patient to exercise in a standardized manner, which is in line with the muscle rehabilitation pattern of PICC catheter placement patients. A buzzer 210 is fixedly installed at the bottom of the mounting slot 207. The buzzer 210 is electrically connected to the battery 208 to remind the patient to start exercising and improve the compliance of rehabilitation exercise.

[0027] A switch 211 is fixedly installed on the left side of the grip ball 206, which is suitable for patients to operate with one hand and realize independent on / off control of the vibration motor 209 and the buzzer 210. The switch 211 is electrically connected to the battery 208. Several sound-permeable holes 212 are opened through the rear side of the mounting slot 207 through the grip ball 206 to prevent the sound of the buzzer 210 from being muffled by the outer shell of the grip ball 206 and to ensure that the reminder sound is clear.

[0028] The glove body 1 has a fixing component 3 on the back side. The fixing component 3 includes an upper fixing ring 301 fixedly installed on the top of the back side of the glove body 1. Fixing seats 302 are fixedly installed on both the left and right sides of the upper fixing ring 301. Fixing straps 303 are fixedly installed at the bottom of the fixing seats 302 to adapt to patients with different arm sizes and improve the wearing fit.

[0029] A fixing plate 304 is provided on the outer side of the fixing base 302 via a hinge. A buckle 305 is fixed on the rear side of the fixing plate 304 to ensure that the fixing strap 303 does not loosen, thereby improving the fit and stability of wearing.

[0030] A lower fixing ring 306 is fixedly provided at the bottom rear side of the glove body 1. Fixing holes 307 are fixedly provided on both the left and right sides of the lower fixing ring 306 to provide a fulcrum for the fixing strap 303 to pass through.

[0031] The vibration motor and buzzer are existing technologies and will not be described in detail. Additionally, the invention includes a power supply, controller, and switches, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this invention is common knowledge in the field, and its working principle is already known technology. The appropriate model should be selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0032] The working principle and procedure of a PICC placement exercise glove: According to the needs of the patient's rehabilitation stage, select a spring sheet 203 with appropriate elasticity. Install the spring sheet 203 into the grip groove 201 at the bottom of the glove body 1 by engaging the mounting block 204 with the mounting slot 205. Then, install the grip ball 206 at the bottom of the mounting frame 202 by thread engagement. The patient inserts the hand on the side of the catheter into the glove body 1, passes the fixing strap 303 through the fixing holes 307 on both sides of the lower fixing ring 306 and wraps it back to the upper fixing plate 301, flips the fixing plate 304 so that the fixing plate 304 and the fixing seat 302 clamp and fix the fixing strap 303, adjusts the length of the fixing strap 303 to fit the thickness of the patient's arm, and finally fastens the buckle 305 to lock it, thus completing the stable fixation of the glove. The buzzer 210 emits a sound through the sound hole 212 to remind the patient to start the grip exercise. The patient presses the switch 211 on the left side of the grip ball 206 with one hand and performs grip exercise in accordance with the optimal rhythm of the vibration motor 209. The spring plate 203 and the grip ball 206 provide elastic resistance.
