Description

Technical Field

[0001] This application relates to the technical field of seats, and particularly to a mammography examination chair. Background Art

[0002] A mammography machine is a medical research instrument used in the field of clinical medicine. It can diagnose early breast cancer lesions, breast hyperplasia and other diseases. The images are clear, the breast structure is clearly shown, and it has the characteristics of comprehensiveness, intuitiveness, and simple operation. It can be used for follow-up examinations of lesions after radiotherapy and chemotherapy for breast cancer patients, and can also perform regular monitoring on the healthy breast.

[0003] The existing detection method generally requires the patient to take a natural standing position, place both breasts on the support plate of the mammography machine according to the requirements of the shooting position (conventional bilateral nipple-caudal position + internal-external oblique position), and perform compression photography. However, during mammography examination and mammography-guided percutaneous biopsy, it takes a long time to follow up, which will cause the standing patients to be quite tired. Therefore, a common chair is now used for the patient to sit for the examination, but there are the following problems: when examining, the patient needs to lean forward appropriately with the upper body close to the mammography machine, and the patient may shrink back due to pain or fear, and the common chair cannot restrain the patient's body posture. In the prior art, a multifunctional seat for mammography puncture positioning (patent application number: 2021200513296) is disclosed. This seat avoids the fatigue of the patient during the examination and the emotion of hating the detection, making the positioning effect of mammography puncture better. However, when using this seat for mammography examination and mammography-guided percutaneous biopsy, only the upper backrest can be set perpendicular to the ground, and the upper body of the patient cannot be tilted forward appropriately, and the body posture of the patient cannot be restrained either. Summary of the Utility Model

[0004] The technical problem to be solved by this application is to provide a mammography examination chair that can adjust the forward tilt angle of the patient and restrain the patient from moving around randomly.

[0005] To solve the above technical problem, this application adopts the following technical solutions:

[0006] A mammography examination chair includes a lifting base. A seat cushion is provided at the top of the lifting base. It also includes a backboard for supporting the patient's back. A top-back component that can move up and down is provided on the backboard. The top-back component includes a first guide rod. A first guide sleeve is provided on the first guide rod. A back pad is provided at the front end of the first guide sleeve. A first spring is sleeved on the first guide rod. A shoulder fixing component that can move up and down is also provided on the backboard. The shoulder fixing components are respectively arranged on both sides of the top-back component. The patient sits on the seat cushion. The seat cushion is lifted by the lifting base until the patient's shoulders contact the shoulder fixing components. At this time, the back pad corresponds to the patient's back. The back pad pushes the patient's back forward, making the patient's body lean forward slightly. The shoulder fixing components can solve the problem of the patient's round shoulders and hunched back, and open the chest cavity.

[0007] In order to enable the back cushion to push the patient's back forward, causing the back to tilt and minimizing the gap between the back and the back plate, in some embodiments, the back cushion is in the shape of an airbag, protruding forward above and gradually tilting towards the front end face of the back plate below.

[0008] Compared with the prior art, the present application at least achieves the following beneficial effects: When the patient sits on the examination chair and the seat cushion is raised by adjusting the lifting base, the patient's shoulders will contact the shoulder fixing plate of the shoulder fixing component. During the examination, through the restraint of the back pushing component and the shoulder fixing component, the situation of the patient shrinking backward or shaking the body is reduced; by inflating the back cushion, the upper body of the patient can be driven to lean forward. Due to the restraint of the shoulder fixing component, when leaning forward, the problem that the patient cannot independently maintain a straight upper body due to round shoulders and hunchback can be greatly reduced.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The present application will be described in detail below with reference to the exemplary embodiments in the accompanying drawings. It should be understood, however, that the present application can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided herein to make the disclosure of the present application more complete and to fully convey the concept of the present application to those skilled in the art.

[0016] In the description of the present application, it should be understood that the orientation or positional relationship indicated by the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as limiting the protection scope of the present application.

[0017] In view of the defects in the prior art that the body posture of the patient cannot be restricted and the upper body of the patient cannot be tilted appropriately close to the mammography machine. After careful analysis, the inventor found that the main reason for the above problems in the existing ordinary chair is that patients who cannot stand for a long time or need puncture biopsy under the guidance of mammography sit on the chair. During the examination, the upper body of the patient needs to lean forward appropriately to make the chest close to the mammography machine. When compression photography is performed, the patient may feel pain, and the body may have a physiological reaction, will shrink back, and even the lower limbs will kick the ground, resulting in the body moving backward and upward, which will cause the patient's body to move away from the mammography machine. And now there is no chair that can both guide the upper body of the patient to lean forward and restrict the body posture of the patient. Based on the above analysis, the inventor has improved the structure of the chair used for mammography examination.

[0018] As Figures 1-4 shown, in an embodiment of the mammography examination chair of the present application, the examination chair includes a lifting base 1. The structure of the lifting base 1 refers to the structure of a computer chair, and the air rod can be lifted by adjusting the handle. A soft seat cushion 2 is provided on the top of the lifting base 1, and armrests 3 are respectively provided on the left and right sides of the seat cushion 2. This examination chair further includes a backrest 4 for supporting the patient's back. The bottom of the backrest 4 is bent forward, and a collar is provided at the front end of the bend. The collar is sleeved on the outer wall of the protective sleeve of the air rod and is fixed by a plurality of bolts. A backrest pressing assembly that can move up and down is provided on the backrest 4, which can press the patient's back forward. The backrest pressing assembly includes a first guide rod 16, a first guide sleeve 18 is provided on the first guide rod 16, a back pad 7 is provided at the front end of the first guide sleeve 18, and a first spring 17 is sleeved on the first guide rod 16; a shoulder fixing assembly that can move up and down is also provided on the backrest 4, and the shoulder fixing assemblies are respectively provided on both sides of the backrest pressing assembly.

[0019] Adjust the seat cushion 2 to the lowest position. The patient sits on the seat cushion 2. At this time, the back pad 7 and the shoulder fixing assembly are located above the patient's back. Lift the seat cushion 2 through the lifting base 1, and the patient moves up until the patient's shoulders contact the shoulder fixing assembly. At this time, the back pad 7 corresponds to the patient's back exactly. The back pad 7 presses the patient's back forward, making the patient's body lean forward slightly. The shoulder fixing assembly can solve the problem of the patient's round shoulders and humpback, and open the chest cavity.

[0020] In order to enable the backrest 7 to move up and down on the backboard 4, a first hollow groove is provided in the middle of the front end of the backboard 4, and a first guide rod 16 is vertically arranged in the first hollow groove. In this way, the guide sleeve sleeved on the first guide rod 16 can move up and down in the first hollow groove, thereby driving the backrest 7 to move.

[0021] The function of the backrest 7 is to push the patient's back forward to make the back inclined and minimize the gap between the back or the lower back and the backboard 4. The backrest 7 is preferably made of an airbag structure, or a general soft pad 20 can also be used; the structure of the backrest 7 is as Figure 3 shown, with the upper part protruding forward, so that the chest can be guided further forward. The lower part of the backrest 7 gradually inclines towards the front end face of the backboard 4 to adapt to the posture of the upper body leaning forward.

[0022] Among them, as Figure 4 shown, between the first guide sleeve 18 and the backrest 7, there is a rigid bottom plate 19 to support the backrest 7. The bottom plate 19 can separate the backrest 7 from the backboard 4, so that the backrest 7 does not contact the backboard 4, and the generated frictional force is small, which will not affect the up and down movement of the backrest 7.

[0023] Before the backrest 7 is used, it should be kept above the patient's back. In this way, when the seat cushion 2 rises, the patient's back can quickly match the backrest 7. Therefore, the first spring 17 is arranged below the first guide sleeve 18, and the guide sleeve connected to the backrest 7 is jacked up to the highest position through the elastic force of the spring.

[0024] A first locking rod 15 is welded to the rear end of the first guide sleeve 18; the rear end of the seat cushion 2 is connected with a connecting rod 11 with both ends bent and the middle straight. A first lock 12 that is movably connected to the first locking rod 15 is arranged on the connecting rod 11. Sometimes, for patients of different body types, when the seat cushion 2 rises, their feet may separate from the ground. In this case, when undergoing a long-term examination, with the thighs pressing on the seat cushion 2 and the calf muscles in a contracted state for a long time, the patient will feel uncomfortable. Therefore, when the patient raises the shoulders against the shoulder fixing component, at this time, the first lock 12 is sleeved on the first locking rod 15, the first lock 12 is locked, and then the seat cushion 2 is lowered. The backrest 7 will follow the seat cushion 2 and the patient to descend, so that the sitting posture of the patient reaches a relatively relaxed state.

[0025] The function of the shoulder fixing component is to limit the upward or left and right movement of the patient's shoulders. Secondly, it can also position the relative position of the back and the backrest 7. The shoulder fixing component includes a shoulder fixing plate 5, a second guide sleeve 13, a second guide rod 14 and a second spring 10. The shoulder fixing plate 5 is generally arc-shaped and is arranged at the front end of the backboard 4. The rear end of the shoulder fixing plate 5 is connected with a second guide sleeve 13. The second guide sleeve 13 is sleeved on the second guide rod 14, and a second spring 10 is sleeved on the second guide rod 14. The second spring 10 is arranged at the bottom of the second guide sleeve 13.

[0026] Among them, second hollow grooves are respectively opened on the back plate 4 and on the left and right sides of the first hollow groove, and the second guide rod 14 is vertically arranged in the second hollow groove, with the same purpose as that of the aforementioned back pad 7 being able to move up and down.

[0027] A vertical second locking rod 9 is disposed at the rear end of the second guide sleeve 13, and a second locking buckle 12 is disposed on the connecting rod 11 and is movably connected to the second locking rod 9. As mentioned above, when patients of different body types are lowered, their shoulders should be fixed as much as possible. At this time, the second locking buckle 12 is sleeved on the second locking rod 9, the second locking buckle 12 is locked, and then the seat cushion 2 is lowered. The shoulder fixing plate will follow the seat cushion 2 and the patient to lower together, so that the patient can maintain a relatively relaxed sitting posture with his shoulders still fixed.

[0028] The structures of the first locking buckle 12 and the second locking buckle 12 may refer to a tube buckle, a cam locking buckle, a cam clip, etc.

[0029] In order to reduce the pain caused by the shoulder fixing plate pressing the patient's shoulder, a soft pad 20 is glued to the bottom surface of the shoulder fixing plate.

[0030] A push-pull handle 6 is provided at the upper rear end of the back plate 4, and a brakeable wheel 8 is provided at the bottom of the lifting base 1. The patient sits on the cushion 20, and the medical staff can hold the push-pull handle 6 to push the examination chair in front of the molybdenum target machine, and then after adjusting a series of operations, brake the wheel 8 to keep the examination chair stationary.

[0031] A soft cover can be put on the outside of the back plate 4, and the soft cover is like the structure of the outer cover of a massage machine to improve the comfort of the patient. Some openings are provided on the soft cover to expose structures such as the shoulder fixing plate 5 and the back pad 7.

[0032] When in use, the patient is helped onto the cushion 2, and then the patient's back leans against the backboard 4, and the cushion 2 is raised so that the patient's shoulders are in contact with the shoulder fixing plate. At this time, the patient's back is pushed forward by the back pad 7, and the patient's upper body will lean forward. Because the shoulders are constrained by the shoulder fixing plate, the chest will be pushed forward and opened. Then the medical staff pushes the patient to the front end of the molybdenum target machine through the molybdenum target examination chair. After adjusting other settings, the examination can be carried out.

[0033] After the examination, the seat cushion 2 is lowered and the patient can be helped out of the examination chair; if the shoulder fixing plate and the back pad 7 are moved downward by locking the first lock buckle 12 and the second lock buckle 12, after the examination, the first lock buckle 12 and the second lock buckle 12 are released, and the first spring 17 and the second spring 10 respectively lift the first guide sleeve 18 and the second guide sleeve 13 through elastic force, and the shoulder fixing plate rises and resets first, and after the patient's back is no longer in contact with the back pad 7, the back pad 7 also rises and resets.

[0034] Figure 3The dash-dot line slanting to the left is used to indicate the angle of the patient's back tilt.

[0035] It should be understood that all of the above embodiments are exemplary rather than restrictive. Under the concept of this application, various modifications or deformations made by those skilled in the art to the specific embodiments described above should fall within the protection scope of this application.
