Description

Technical Field

[0001] This utility model relates to the field of medical nursing technology, specifically a sandbag compression device. Background Technology

[0002] Interventional surgery is a novel treatment method that falls between surgical and medical treatment. Guided by medical imaging equipment, such as X-rays, CT scans, and ultrasound, interventional surgery involves inserting specific instruments into the body through natural orifices or tiny incisions to treat the lesion. Doctors can accurately deliver the instruments to the lesion site under real-time monitoring of the imaging equipment for diagnosis and treatment. Femoral artery puncture is an important preparatory procedure before interventional surgery. The femoral artery is one of the largest arteries in the human body. Puncture of the femoral artery establishes a channel into the circulatory system, providing a pathway for the insertion of various instruments and catheters during interventional surgery, allowing doctors to accurately deliver the treatment devices to the lesion site. After the procedure, pressure is applied to stop bleeding at the femoral artery puncture site.

[0003] Chinese patent CN217310456U proposes a pressure sandbag fixation device, including a flat ties, a sandbag fixing strap, a male Velcro strap, and a female Velcro strap. The sandbag fixing strap is fixedly attached to the middle of the rear end face of the flat ties, with its left side, lower edge, and right side fixed to the rear end face of the flat ties. Its front end face forms a cavity A between the front end face and the middle of the rear end face of the flat ties. The male Velcro strap is fixed to the middle of the rear end face of the flat ties, and the female Velcro strap is fixed to the front end face of the sandbag fixing strap. The pressure applied by the sandbag in cavity A to the puncture point of the patient's limb for hemostasis is controllable and adjustable. When the flat ties are tightly wrapped around the patient's limb, they are not easy to shift or slip off.

[0004] However, the technical solution of this patent has the following problems:

[0005] 1. This patented device uses a pressure sandbag inside cavity A to apply pressure to the puncture site of the patient's limb for hemostasis. The pressure is controllable and adjustable. When the flat ligature is wrapped tightly around the patient's limb, it is not easy to shift or slip off. However, this device has the problem of not being able to quickly replace the sandbag. For some patients who have difficulty turning over, when the sandbag at the puncture site is contaminated with liquid, it is necessary to replace the sandbag without removing the ligature. This eliminates the need to tighten and adjust the ligature, which can avoid discomfort to the patient and ensure that the pressure of the sandbag is moderate.

[0006] 2. This patent does not allow for adjustment of the compression position by removing the straps on the same side without the patient lifting their leg, making real-time position adjustment inconvenient.

[0007] Therefore, those skilled in the art have provided a sandbag compression device to solve the above-mentioned problems. Utility Model Content

[0012] Furthermore, the connecting mechanism includes a connecting plate and a heightening plate. The connecting plate is provided with multiple strip-shaped openings. The connecting plate is sewn to the side wall of the bag body through the strip-shaped openings. The heightening plate is fixedly installed on the side of the connecting plate away from the bag body.

[0013] Furthermore, the sliding mechanism includes a fixed plate and a sliding plate, wherein the fixed plate is fixedly installed at the end of the heightening plate away from the connecting plate, the sliding plate is slidably connected to the fixed plate, and a slot is provided on the upper side of the sliding plate;

[0014] Furthermore, the locking mechanism includes: an irregularly shaped rod and a first spring, the irregularly shaped rod being slidably connected to the upper side of the fixing plate, the first spring being disposed on the irregularly shaped rod, the upper side of the first spring being in close contact with the fixing plate, and the lower side of the first spring being in close contact with the irregularly shaped rod;

[0015] Furthermore, the waist fixation device includes a waist belt assembly and a waist fixation assembly. A waist belt assembly is installed on the side of the sliding plate of the sliding mechanism of each rear pocket quick-release device away from the fixed plate. The waist fixation assembly is installed on the side of the waist belt assembly away from the sliding plate. The waist belt assembly includes a fixed waist belt and an elastic waist belt. The fixed waist belt is fixedly installed on the side of the sliding plate away from the fixed plate. The fixed waist belt is thicker to prevent pressure sores. The elastic waist belt is fixedly installed on the side of the fixed waist belt away from the sliding plate. The elastic waist belt is an elastic fabric strip.

[0016] Furthermore, the waist fastening assembly includes: a second hook and loop fastener male side and a second hook and loop fastener female side, the second hook and loop fastener male side being fixedly installed on the left side of the elastic waistband away from the fixed waistband, and the second hook and loop fastener female side being fixedly installed on the right side of the elastic waistband away from the fixed waistband.

[0017] Furthermore, the leg fixing device includes: a leg strap and an anti-accidental contact device. A leg strap is installed on the side of the sliding plate of the sliding mechanism of each front pocket quick-release device away from the fixing plate. The leg strap is an elastic cloth strap. The anti-accidental contact device is installed on the side of the leg strap away from the sliding plate.

[0018] Furthermore, the anti-accidental touch device includes: a fixing mechanism and a buckling mechanism. The fixing mechanism is installed on the left leg strap on the side away from the sliding plate, and the buckling mechanism is installed on the right leg strap on the side away from the sliding plate. The buckling mechanism includes: a protrusion and a fixing rod. The protrusion is fixedly installed on the right leg strap on the side away from the sliding plate, and the fixing rod is fixedly installed on the protrusion on the side away from the right leg strap.

[0019] Furthermore, the fixing mechanism includes: a housing, a rotating knob, a second spring, and a baffle. The housing is fixedly installed on the left side of the leg strap away from the sliding plate. The rotating knob is rotatably connected to the housing. The rotating knob has an irregularly shaped slot. The rear side of the irregularly shaped slot can accommodate the passage of a fixing rod, while the right side of the irregularly shaped slot cannot accommodate the passage of a fixing rod. One end of the second spring is fixedly installed on the side wall of the rotating knob, and the other end of the second spring is fixedly installed on the front side inside the housing. The baffle is fixedly installed on the left side inside the housing. The baffle is used to limit the rotation range of the rotating knob. When the rotating knob is rotated, the second spring is stretched, allowing the rear side of the irregularly shaped slot on the rotating knob to move to the position of the fixing rod. The fixing rod is placed into the irregularly shaped slot. When the rotating knob is released, the stretched second spring returns to its original position, moving the rotating knob to its initial position. At this time, the right side of the irregularly shaped slot on the rotating knob moves to the position of the fixing rod. Since the right side of the irregularly shaped slot cannot accommodate the passage of the fixing rod, the fixing rod is quickly stuck in the rotating knob. It is necessary to rotate the rotating knob to move the protrusion and the housing to separate them.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By moving the sliding plate into the fixed plate, the sliding plate moves the irregular rod upward, which compresses the first spring. When the slot on the upper side of the sliding plate moves to the position of the irregular rod, the compressed first spring returns and pushes the irregular rod downward, so that the irregular rod enters the slot, thereby locking the sliding plate. To remove the sliding plate, the irregular rod is moved upward so that the lower side of the irregular rod leaves the slot, which compresses the first spring. The sliding plate is then moved away from the fixed plate, the irregular rod is released, and the compressed first spring returns and pushes the irregular rod back to the initial position, thus removing the sliding plate. This is beneficial for patients with difficulty turning over to quickly change contaminated sandbags and reduces the physical discomfort of patients when changing sandbags.

[0021] 2. By moving the two leg straps of the leg fixation device to a suitable position and connecting them with an anti-accidental contact device, the front of the bag is fixed to the patient's leg. The outer shell of the left leg strap is moved to the right, and the protrusion of the right leg strap is moved to the left. Rotating the knob stretches the second spring, allowing the rear of the irregularly shaped slot on the knob to move to the fixed rod position. Moving the protrusion to the left causes the fixed rod to move to the left and enter the irregularly shaped slot. Releasing the knob returns the stretched second spring to its initial position. At this point, the right side of the irregularly shaped slot on the knob moves to the fixed rod position. Since the right side of the irregularly shaped slot cannot accommodate the fixed rod, it is quickly locked inside the knob. This allows for easy control of locking and unlocking of the fixed rod by rotating the knob. Moving the protrusion and outer shell separates the two leg straps, allowing for locking and unlocking by rotation. This reduces accidental contact caused by patient leg movement and facilitates adjusting the pressure position by removing the straps on the same side without the patient lifting their leg, enabling convenient real-time position adjustments.
