Description

Technical Field

[0001] The utility model relates to the technical field of radiotherapy positioning pads, in particular to a human body positioning pad that can be quickly shaped. Background Art

[0002] During radiotherapy, emergency treatment or surgery, the human body needs to maintain a specific posture until the entire treatment is completed, and the patient faces repeated positioning during the entire treatment. Because there are many patients, clinicians need a human body positioning cushion that is easy to operate, safe and reliable to fix the patient. There are two commonly used cushions on the market: vacuum positioning cushions and shaping cushions.

[0003] The vacuum positioning pad is a sealed composite sealing pad filled with polystyrene particles. The patient lies on a soft bag filled with air, and the body contour is pressed out by the body's own weight. The air in the bag is then extracted by a vacuum pump to form a negative pressure state inside the positioning pad, thereby fixing the patient's body. This method is easy to operate, but has high requirements for sealing. Scratches during use may cause the previous work to fall short, thus having a significant impact on the treatment.

[0004] The shaping pad is composed of a thermoplastic shell and internal snowflake mud. When heated to an appropriate temperature, the shaping pad becomes plastic, thereby fixing the human body. When the shaping pad cools, the shell becomes hard, and the patient's body contour is maintained. However, this product still has the following problems: First, the shell material absorbs radiation, which brings inconvenience to doctors; second, the internal snowflake mud has both heat insulation and thermal insulation effects. As a result, the softening time of the surface shell is prolonged due to the influence of heat insulation, and the hardening time is also prolonged. Utility Model Content

[0005] In view of the problems existing in the prior art, the utility model provides a human body positioning pad which can be quickly shaped.

[0006] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0007] The utility model provides a human body positioning pad that can be quickly shaped, comprising: a sealing pad body, an outer shape limiting frame arranged on the sealing pad body and used to limit the shape of the sealing pad body, an inflatable bag arranged on the outer shape limiting frame and used to squeeze the patient, and an injector; the sealing pad body is provided with a glue injection port;

[0008] The sealing gasket body is pre-installed with A or B type adhesive and low-density particle premix, and correspondingly, the injector is pre-installed with B or A type adhesive; the injector is used to inject A or B type adhesive into the sealing gasket body through the injection port to mix and solidify with the A or B type adhesive and low-density particles in the sealing gasket body;

[0009] Alternatively, the sealing gasket body is pre-installed with non-premixed low-density particles, and correspondingly, the injector is respectively encapsulated with type A adhesive and type B adhesive; the injector is used to inject type A adhesive and type B adhesive into the sealing gasket body through the injection port to blend and solidify with the non-premixed low-density particles inside the sealing gasket body.

[0010] Preferably, the low-density particles are low-density inorganic or organic material particles.

[0011] Preferably, the edge of the sealing gasket body is provided with the glue injection port, and the glue injection port is composed of a rubber hose or a fluid pipeline interface.

[0012] Preferably, the exterior of the sealing pad body is made of plastic or fiber woven cloth.

[0013] Preferably, the injector is bottle-shaped, made of plastic or glass, and has a glue injection port at the top.

[0014] Preferably, the inflatable bag comprises a head and shoulder filling bag and a body filling bag; the inflatable bag can be inflated during shaping to squeeze the sealing cushion body toward the inside of the body.

[0015] Preferably, the shape limiting frame comprises a head-shoulder shape limiting frame and a body shape limiting frame; the head-shoulder shape limiting frame is also provided with the head-shoulder filling airbag, and the body shape limiting frame is also provided with the body filling airbag.

[0016] Preferably, the head and shoulder filling airbags are arranged on both sides of the head and shoulder shape limiting frame, and the body filling airbags are arranged on both sides of the body shape limiting frame.

[0017] The technical solution of the utility model has the following beneficial effects:

[0018] The utility model solves the risk of air leakage of the vacuum sealing pad: through the curing of the adhesive, it can be permanently preserved without worrying about air leakage;

[0019] The operation process is controllable: by controlling the pre-installed adhesive injector to inject type B or type A adhesive into the gasket body, or adjusting the amount of type A adhesive and type B adhesive to adjust the ratio of AB adhesive, the hardening time can be controlled within 5-15 minutes. Compared with the existing thermoplastic positioning pads, the hardening time can be shortened by at least 2 / 3;

[0020] Reduced radiation absorption: low-density particles are mixed with a small amount of adhesive to reduce the impact of radiation;

[0021] Better fit for the patient's body shape: The outside is equipped with a positioning frame, and the inside of the frame adopts an inflatable airbag structure. The size of the airbag can be adjusted according to the body shape, and the airbag presses the positioning cushion until it hardens;

[0022] The low-density particles are bonded with adhesive, and the two-component feature allows for rapid curing. When used in conjunction with a positioning frame, the human positioning pad can fit the human body better, making it easier for patients to repeat positioning. BRIEF DESCRIPTION OF THE DRAWINGS
