Problems solved by technology

[0004] In the prior art, the porous thermoplastic mesh is used to position the patient, so as to accurately position the patient during repeated chemotherapy. However, due to the fixed shape of the bed, it is difficult to adapt to the body shape of different patients and fix it comfortably. At the same time, during the chemotherapy process, the patient needs to Keep a certain posture for a long time, but long-term fixation will easily increase the discomfort of the patient, which is not conducive to the stable fixation and precise chemotherapy of the patient

Embodiment 1

[0031] Such as figure 1 , image 3As shown, a patient position fixing device for tumor radiotherapy described in the embodiment of the present invention includes a base 1, a lifting unit 11, and a bed 12 arranged sequentially from bottom to top; There is an arc-shaped non-woven fabric 13; a dividing plate 14 is fixedly connected with the corresponding position of the non-woven fabric 13 in the bed body 12, and a molten pool 15 is provided in the bed body 12 at the bottom of the dividing plate 14, and a molten pool 15 is provided at the bottom of the molten pool 15. There are heating wires 16, and the melting pool 15 is filled with hot melt glue; a group of sliding rods 17 are evenly distributed on the partition 14, and the sliding rods 17 pass through the partition 14 and are slidably connected with the partition 14, and one end of the sliding rod 17 is against the The other end of the non-woven fabric 13 extends to the inside of the molten pool 15; the sliding rod 17 slides ...

Embodiment 2

[0039] Such as figure 2 , Figure 7 Shown, comparative example one, wherein another kind of implementation mode of the present invention is:

[0040] The partition plate 14 on one side of the slide bar 17 is fixedly connected with an electric push rod 4, the output end of the electric push rod 4 is fixedly connected with a push rod 41, and the position of the push rod 41 near the slide rod 17 is fixedly connected with a wedge-shaped block 42; After the wedge-shaped block 42 slides, squeeze the slide bar 17 tightly, initially fix the slide bar 17, reduce the influence of the patient's slight movement on the positioning effect of the slide bar 17, fill the empty window period when the hot melt adhesive cools, and further increase the hot melt after curing. The supporting effect of the glue on the slide bar 17 keeps the fit between the top of the slide bar 17 and the body shape of the patient.

[0041] The push rod 41 is an elastic rod, and the wedge-shaped block 42 is provide...

Abstract

The invention belongs to the technical field of tumor radiotherapy auxiliary equipment, and particularly relates to a patient body position fixing device for tumor radiotherapy, which comprises a base, a lifting unit and a bed body which are sequentially arranged from bottom to top, an arc-shaped non-woven fabric is fixedly connected into a groove formed in the top of the bed body; a partition plate is fixedly connected to the position, corresponding to the non-woven fabric, in the bed body, a molten pool is formed in the bed body at the bottom of the partition plate, a heating wire is arranged at the bottom of the molten pool, and the molten pool is filled with hot melt adhesive. A group of sliding rods are uniformly distributed on the partition plate, penetrate through the partition plate and are in sliding connection with the partition plate, one end of each sliding rod abuts against the non-woven fabric, and the other end extends into the molten pool; the sliding rod is controlled by a driving unit to slide up and down; hot melt adhesive in a molten pool is heated and softened through an electric heating wire, then a patient lies flat on non-woven fabric and extrudes a sliding rod, and the sliding rod slides to carry out high-fitting supporting on different body types of the patient, so that the comfort of the patient is improved, the chemotherapy precision is improved, and unnecessary radiation damage is reduced.

Description

technical field [0001] The invention belongs to the technical field of tumor radiotherapy auxiliary equipment, in particular to a patient position fixing device for tumor radiotherapy. Background technique [0002] Radiation therapy for tumors is a local treatment method that uses radiation to treat tumors. During radiotherapy, the patient needs to be stably positioned so that the radiotherapy can be performed accurately and the impact on the normal organs of the patient can be reduced. [0003] A Chinese patent with the publication number CN213667599U discloses a tumor radiotherapy auxiliary device, including an auxiliary splint, a lifting auxiliary plate is provided on one side of the auxiliary splint, and a movable radiotherapy concentration box is provided on the right side of the auxiliary splint. The bottom of the auxiliary splint is fixedly connected with a radiation therapy support plate, the top of the auxiliary splint is fixedly connected with a first radiation th...
