Height-adjustable headrest special for Haijiao treatment

Abstract

The utility model discloses a height-adjustable headrest special for Haijiao treatment. The height-adjustable headrest comprises a headrest body. The headrest is a cylinder with a C-shaped section, a notch used for avoiding the mouth and the nose is formed in the headrest, the headrest is formed by stacking a plurality of C-shaped sheet-shaped split bodies, and an avoiding groove used for containing an oxygen inhalation tube is formed in the C-shaped sheet-shaped split body at the uppermost end. When the oxygen uptake tube is used, the oxygen uptake tube is contained in the receding groove, face indentation is effectively avoided, and therefore pressure damage to the cheek part is avoided. When the adjustable headrest is used, the number of the C-shaped sheet-shaped split stacked sheets in the headrest can be increased or decreased, so that the purpose of adjusting the height of the headrest is achieved, and the requirements of patients with different body types on the height of the headrest are met.

Description

Technical Field

[0001] The utility model relates to the technical field of medical supplies, in particular to a height-adjustable headrest specially used for HIFU treatment. Background Art

[0002] High-intensity focused ultrasound ablation (HIFU) or "HIFUa" in English, is transliterated as "HIFU treatment" in Chinese. This is a new technology that can kill tumors in the body without cutting the abdominal wall or puncturing. Similar to how sunlight can be focused through a convex lens, ultrasound can also be focused and can safely penetrate human tissue. As a non-invasive treatment option, HIFU treatment focuses extracorporeal ultrasound energy into the body and uses the thermal, mechanical and cavitation effects generated by high-intensity ultrasound to instantly make the target tissue reach a high temperature of more than 60°C, causing coagulative necrosis to occur, thereby achieving the purpose of treating tumors. Necrotic tissue can be gradually absorbed or form scars (fibrosis), while tissues outside the sound channel will hardly be harmed.

[0003] HIFU treatment is suitable for gynecological solid tumors and diseases, such as: ovarian liver cancer metastasis, retroperitoneal lymph node metastasis, uterine fibroids, adenomyosis, placenta accreta, uterine scar pregnancy after cesarean section, abdominal wall endometriosis, uterine horn pregnancy, functional uterine bleeding, etc. The patient needs to lie on the treatment bed in a prone position (face, chest, abdomen facing down), with the lower abdomen facing the sink with the ultrasound treatment head. The doctor then uses the ultrasound image display on the operating table to adjust the treatment focus to the target tissue, and then controls the treatment head to rise so that it fits the patient's skin, and then starts the treatment. Oxygen is usually inhaled through an oxygen tube during the treatment.

[0004] Existing focused ultrasound tumor treatment systems are usually equipped with a special treatment headrest, which is a cylindrical body with an "Ω"-shaped cross-section and a hollow area in the middle. The upper surface of the headrest is used to support the patient's face and expose the patient's mouth and nose in the hollow area to facilitate breathing.

[0005] The existing special treatment headrests have the following shortcomings: 1. The height cannot be adjusted. For patients of different heights, weights and body shapes, the appropriate headrest height is also different. The duration of HIFU treatment can be up to 1-4 hours. If the height of the headrest is not suitable, it is easy to cause neck pain over time. 2. It is easy to cause pressure damage. After the patient wears an oxygen tube, the oxygen tube will extend along the cheek to the back of the ear. When the patient rests on the headrest, the oxygen tube will be pressed between the cheek and the headrest, which is easy to cause pressure damage to the cheek skin over time. Summary of the invention

[0006] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a height-adjustable headrest for HIFU treatment, which solves the problem that the height of the existing headrest for HIFU treatment cannot be adjusted and cheek pressure damage is easily caused.

[0007] The technical scheme of the utility model is: a height-adjustable headrest specially used for HIFU treatment, comprising a headrest; the headrest is a columnar body with a C-shaped cross section, on which a notch for avoiding the mouth and nose is provided, and the headrest is formed by stacking a plurality of C-shaped sheet splits, and a avoidance groove for accommodating an oxygen inhalation tube is provided on the uppermost C-shaped sheet split; openings are provided on the C-shaped sheet splits, and the cross-sectional shapes of each C-shaped sheet split are consistent; the notch of the headrest is formed by stacking the openings of all the C-shaped sheet splits constituting the headrest; the avoidance grooves are distributed on both sides of the opening of the C-shaped sheet split at the uppermost end of the headrest; any two adjacent C-shaped sheet splits of the headrest are connected by Velcro.

[0008] Compared with the prior art, the utility model has the following advantages:

[0009] 1. When in use, the oxygen tube is contained in the avoidance groove, which effectively avoids facial indentations and thus avoids pressure damage to the cheek area.

[0010] 2. When in use, the number of C-shaped sheet-like split overlapping sheets in the headrest can be increased or decreased, so as to achieve the purpose of adjusting the height of the headrest to meet the needs of patients with different body shapes for the height of the headrest.

[0011] The utility model is further described below in conjunction with the figures and embodiments. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of the structure of the utility model;

[0013] Figure 2 Schematic diagram of the distribution position of Velcro on the C-shaped sheet. DETAILED DESCRIPTION

[0014] like Figure 1-2 As shown, a height-adjustable headrest for HIFU treatment includes a headrest. The headrest is a columnar body with a C-shaped cross section, on which a notch 100 for avoiding the mouth and nose is provided. The headrest is formed by stacking multiple C-shaped sheet splits 1, and the uppermost C-shaped sheet split 1 is provided with a avoidance groove 11 for accommodating an oxygen inhalation tube. The C-shaped sheet split 1 is provided with an opening 12, and the cross-sectional shape of each C-shaped sheet split 1 is consistent; the notch 100 of the headrest is formed by the stacking of the openings 12 of all the C-shaped sheet splits 1 that constitute the headrest.

[0015] Preferably, the avoidance grooves 11 are distributed on both sides of the opening of the C-shaped sheet-like split body at the uppermost end of the headrest.

[0016] Preferably, any two adjacent C-shaped sheet splits 1 of the headrest are connected by Velcro, which includes a nylon hook tape and a nylon velvet tape. The nylon hook tape and the nylon velvet tape are respectively arranged on the end surfaces of two adjacent C-shaped sheet splits 1 and arranged relatively to each other, wherein the upper end surface of the C-shaped sheet split at the uppermost end of the headrest is not provided with Velcro.

[0017] Brief description of the use of the utility model: Before HIFU treatment, the number of C-shaped sheet splits 1 in the headrest is appropriately increased or decreased according to the patient's body shape, and the height of the headrest is adjusted to be suitable for the patient. The patient lies on the treatment bed in a prone position, with the face facing down on the headrest, the mouth and nose are accommodated in the notch 100, and the position of the oxygen inhalation tube is adjusted so that the oxygen inhalation tube is accommodated in the avoidance groove 11, effectively avoiding pressure damage to the cheek area.
