Description

Technical Field

[0001] The invention relates to the field of cold compress on the outer side of the leg, and in particular to a constant-force telescopic cold compress device on the outer side of the leg. Background Art

[0002] Ice compress is a common and widely used operation technique in clinical work. Orthopedics often have patients with ankle fractures and partially closed tibia and fibula fractures, which are often accompanied by pain at the fracture site and limb swelling. Ice packs are needed to reduce local limb swelling and pain. Physical cooling is performed on patients with high fever. Nursing staff often place ice packs in the axilla, groin and other places with rich blood flow to achieve cooling effects. Studies have also shown that ice packs can also be used to achieve local hemostasis and pain relief for patients with incision pain after fracture surgery. In the process of clinical implementation, ice compress is often applied to the outside of the leg. Compared with the thigh root, ice packs can be supported, but the outside of the thigh is easy to slip off. Even if a restraint belt is put on, it is easy to slide around the leg and lose its effect. Therefore, how to prevent the ice pack from slipping when applying ice compress to the outside of the leg is an urgent problem that technicians in this field need to solve. Summary of the invention

The pulling mechanism provides a constant pulling force, the pull rope passes around the leg, so that the telescopic mechanism is telescopic, and the pressing plate presses against the leg. If the leg moves, the telescopic mechanism will move accordingly, ensuring tight contact and constant pressure.

[0005] Preferably, the telescopic mechanism includes a horizontal tube with a square cross section mounted on the support tube to the left and a telescopic tube sleeved on the horizontal tube, the pressure plate is mounted on the left end of the telescopic tube, and the telescopic tube is adapted to the horizontal tube for telescoping.

An opening is provided at the bottom of the balancing weight ball, and a plug for sealing is inserted into the opening. The weight is adjusted by the amount of water inside. Of course, it can also be other small objects such as sand.

[0008] Preferably, the support tube is sleeved with a height adjustment mechanism that can telescopically move up and down to adjust the height of the pressure plate, and the cross tube is installed on the height adjustment mechanism to adjust the height of the cross tube and the pressure plate to cope with cold compress positions at different heights.

[0009] Preferably, the height adjustment mechanism includes a sleeve sleeved on the support tube, and the transverse tube is installed on the sleeve, and also includes a supporting mechanism arranged between the sleeve and the support tube to support the transverse tube after the height is adjusted.

The support tube passes through the sleeve upward, and a sliding distance is left between the upper end of the sleeve and the upper end of the support tube for the sleeve to move up and down. The upper end surface of the sleeve is located on the lower side of the upper end surface of the support tube. The pull ring is close to the sleeve, and under the traction of the pull rope, the pull ring is driven to apply force to the upper end of the support tube, thereby balancing the gravity and achieving support for the transverse tube. Combined with the pull rope passing around the legs, there is a fixed binding force pulling up and down to balance the pulling force on the pull ring, thereby maintaining the stability of the transverse tube.

Under the traction of the pull rope, the pull ring is driven to apply force to the upper end of the support tube, thereby balancing the gravity and supporting the horizontal tube. Combined with the pull rope passing around the legs, there is a fixed binding force pulling up and down to balance the pulling force on the pull ring, thereby maintaining the stability of the horizontal tube.

The compress bag 4 is arranged on the pressing plate 3, and a pull rope 5 is connected to the lower end of the pressing plate 3, the pull rope 5 passes around the leg from the left side and then extends to the right, penetrates through the upper opening of the support tube 2, and is connected to a pulling mechanism that provides gravity after passing through the side wall of the support tube 2, and under the action of the pulling mechanism, the telescopic mechanism extends toward the leg so that the compress bag 4 rests on the outer side of the leg. The pulling mechanism provides a constant pulling force, and the pull rope 5 passes around the legs, thereby extending and retracting the telescopic mechanism. The pressing plate 3 is pressed against the legs. If the legs move, the telescopic mechanism will move accordingly, ensuring tight contact and constant pressure.

[0018] The telescopic mechanism includes a cross tube 6 with a square cross section mounted on the support tube 2 and facing leftward, and a telescopic tube 7 sleeved on the cross tube 6. The pressing plate 3 is mounted on the left end of the telescopic tube 7. The telescopic tube 7 is adapted to the cross tube 6 for telescopic operation.

[0019] The pulling mechanism includes a weighted ball 8 connected to the end of the pull rope 5. The weighted ball 8 provides traction to enable the pressure plate 3 to drive the compress bag 4 to rest against the leg. The weighted ball 8 is a hollow structure with water inside. An opening is provided at the bottom of the weighted ball 8, and a plug 9 for blocking is inserted at the opening. The weight is adjusted by the amount of water inside.

The support of the support tube 2 and the sleeve 10, plus the winding of the pull rope 5, avoids the problem of slipping and sliding around the leg, and ensures the cold compress position. The pressing plate 3 is arc-shaped, which fits the leg better and is not easy to slide up and down; When the patient's legs move left and right, the telescopic tube 7 is telescoped left and right under the action of the pull rope 5, thereby avoiding slipping and ensuring the cold compress position; Under the traction of the pull rope 5, the pull ring 12 is driven to apply force to the upper end of the support tube 2, thereby balancing the gravity and supporting the cross tube 6. Combined with the pull rope 5 passing around the legs, there is a fixed binding force pulling up and down to balance the pulling force on the pull ring 12, thereby maintaining the stability of the cross tube 6. In this way, after the initial height adjustment, it can move with the up and down shaking of the legs without slipping, and the telescopic tube 7 can also be extended and retracted left and right to ensure a fixed position.
