Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, in particular to a thoracocentesis chair. Background Art

[0002] The conventional puncture position for pleural effusion is sitting. In this position, pleural effusion often accumulates on the back of the lower chest due to gravity, and the puncture point selection range is the largest. It is far away from important organs and the puncture is safer. The traditional puncture method is: the patient sits backwards on a reclining chair, with both forearms overlapped and placed on the upper edge of the chair back, and the forehead rests on the forearms. In this way, ordinary chairs cannot adjust the height, and the back support area is small, which can easily cause the patient to have an incorrect posture and fatigue and discomfort. Sitting backward for a long time will cause obstruction of blood circulation in the upper limbs, leading to limb numbness and pain, which will affect the doctor-patient cooperation and the smooth implementation of puncture. The body position needs to be changed frequently, which causes the ultrasonic positioning mark of the patient to shift before the operation, thereby bringing uncertainty to the puncture site and increasing the surgical risk of the patient. It is especially unsuitable for elderly and critically ill patients. Clinically, patients who need to undergo this operation are often seriously ill, weak, and have poor mobility. Therefore, there is an urgent need for a thoracentesis chair that is easy to get on and off, suitable for tall, short, fat and thin people, retractable, comfortable, fixed, convenient for measuring vital signs, and storage (such as paper towels, convenient bags, etc., for patients with coughing, sputum, and vomiting).

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Traditional chairs have wide seats and fixed heights, which are uncomfortable when used for reverse sitting, and it is even more difficult for patients with poor mobility to get on and off; the utility model provides a thoracocentesis chair, such as Figure 1 As shown, it includes a seat 10 and a seat back 20; the seat 10 is provided with a width adjustment mechanism 11 for adjusting the width of the seat 10, and the seat back 20 is provided with a first height adjustment mechanism 21 for adjusting the height of the seat back 20, so as to adapt to patients with different sizes of buttocks and different chest and back heights, and can be flexibly adjusted according to the patient's body shape and comfort requirements, thereby improving the accuracy of thoracentesis and the patient's experience.

[0020] On the surface of the chair back 20 facing the seat 10 of the utility model, a positioning support 30 for supporting the chest and abdomen is arranged, and the positioning support 30 has an arc-shaped outer contour; the utility model uses the positioning support 30 to support the chest and abdomen. When the patient is weak, the doctor can better control the strength when inserting the tube, and the patient's chest and abdomen are fixed and not easy to move, and the operation is safer; the structure of the arc-shaped outer contour can better contact with the human body, thereby improving the patient's experience.

[0021] In a specific embodiment, the positioning support member 30 is an air cushion, which has a hemispherical structure in the inflated state. When in use, the air cushion can be inflated to expand and bulge to support the chest and abdomen, thereby forming a support point during puncture and facilitating the puncture operation. The air cushion has a certain supporting force and is also flexible, which can improve the fit with the human body, thereby improving the patient's use experience.

[0022] In a specific embodiment, the positioning support member 30 is a positioning protrusion extending in a direction perpendicular to the chair back 20, and can be adjusted up and down according to the height of the patient's chest and abdomen. The positioning protrusion has an arc-shaped outer contour; the positioning support member 30 and the chair back 20 can be an integral structure or an external component. The positioning protrusion is used to support the chest and abdomen, facilitate the formation of a support point during puncture, and facilitate the puncture operation; in order to further improve the patient's user experience, a flexible material layer can be wrapped around the positioning protrusion.

[0023] In a specific embodiment, in a traditional chair, the backrest 20 has a small support area, which can easily cause the patient to have an incorrect posture and fatigue and discomfort. Long-term backward sitting causes obstruction of blood circulation in the upper limbs, leading to limb numbness and pain, which affects the doctor-patient cooperation and the smooth implementation of puncture. In this embodiment, the backrest 20 is extended outward to provide an arm support board 40. The arm support board 40 is horizontally arranged to support the patient's arms. The length of the arm support board 40 is designed according to the length of both arms of an adult patient. At the same time, the arm support board 40 can also be used as a place to place items that are needed at any time. It is convenient and stable, and it is convenient for medical staff to measure vital signs when necessary.

[0024] In a specific embodiment, the seat 10 is provided with a second height adjustment mechanism 12 for adjusting the height of the seat 10, which is used to adjust the height of the seat 10 according to patients of different body shapes to adapt to the height and leg length of different patients; the second height adjustment mechanism 12 can be set on the base of the seat 10, that is, on the chair leg, or it can be set between the base and the surface of the seat 10, which is not limited here.

[0025] In a specific embodiment, the second height adjustment mechanism 12 can be at least one of a lifting screw structure, a slide rail structure, a telescopic rod structure, and a gas spring structure. The lifting screw structure realizes the lifting and lowering of the height of the seat 10 by the cooperation of the screw and the nut. When the screw is rotated, the nut will move up and down along the screw, thereby driving the seat 10 to rise or fall. The lifting screw structure has the characteristics of simple structure, stable adjustment, and relatively low cost. The slide rail structure is usually composed of two parallel slide rails and a slider matched therewith. The slider can slide freely on the slide rail. The height adjustment of the seat 10 can be achieved by fixing the connector at the bottom of the seat 10. The slide rail structure has a large adjustment range and is easy to operate, but it is necessary to ensure the stability of the slide rail and the stability of the slider. The gas spring structure uses the compression and expansion of gas to adjust the height of the seat 10. By controlling the inflation amount of the gas spring, the height of the seat 10 can be easily adjusted. The gas spring structure has the characteristics of fast adjustment speed and good stability.

[0026] In a specific embodiment, the width adjustment mechanism 11 and / or the first height adjustment mechanism 21 are provided with identification pieces or scale lines for identifying the degree of adjustment, so that patients or medical staff can intuitively understand the degree of adjustment.

[0027] In a specific embodiment, Figure 1-Figure 2As shown, the width adjustment mechanism 11 can be at least one of a slide plate mechanism, a flap mechanism, a hydraulic mechanism or a spiral structure. The slide plate mechanism controls the width of the seat 10 by moving the slide plate. The slide plate slides on the slide rail and can expand or contract to both sides as needed, thereby changing the overall width of the seat 10. The slide plate mechanism has a simple and compact structure and high reliability. The hydraulic mechanism uses hydraulic oil to control the width of the seat 10. Through the expansion and contraction of the hydraulic cylinder, the width of the seat 10 can be adjusted quickly and smoothly. The hydraulic mechanism has the characteristics of high adjustment accuracy and good stability. The spiral mechanism is usually composed of a spiral lifting mechanism and a guide device matched therewith. By rotating the spiral lifting mechanism, the two sides of the seat 10 can be driven to move outward or inward, thereby realizing the adjustment of the width. The spiral mechanism has a large adjustment range and good stability; the flap structure connects multiple boards through a hinge mechanism, the board mainly used for sitting is placed on the top, and the other boards are arranged at the bottom. When the width needs to be adjusted, the other boards are folded as needed to achieve the adjustment of the width.

[0028] In a specific embodiment, the first height adjustment mechanism 21 can be at least one of a lifting screw structure, a slide rail structure, a telescopic rod structure, and a gas spring structure. The lifting screw structure realizes the lifting and lowering of the height of the chair back 20 by the cooperation of the screw and the nut. When the screw is rotated, the nut will move up and down along the screw, thereby driving the chair back 20 to rise or fall. The lifting screw structure has the characteristics of simple structure, stable adjustment, and relatively low cost. The slide rail structure is usually composed of two parallel slide rails and a slider matched therewith. The slider can slide freely on the slide rail, and the height of the chair back 20 can be adjusted by a connector fixed at the bottom of the chair back 20. The slide rail structure has a large adjustment range and is easy to operate, but it is necessary to ensure the stability of the slide rail and the stability of the slider. The gas spring structure uses the compression and expansion of gas to adjust the height of the chair back 20. By controlling the inflation amount of the gas spring, the height of the chair back 20 can be easily adjusted. The gas spring structure has the characteristics of fast adjustment speed and good stability. The telescopic rod structure is simple and easy to design.

[0029] In one embodiment, a flexible cushion is provided on the surface of the chair back 20 to improve the comfort of the patient. The base of the chair 10 is wrapped with an anti-skid layer, which is anti-skid and stable, and can be adjusted to cope with uneven ground conditions, which is safer.

[0030] The implementation of the chest chair 10 of the utility model has at least the following beneficial effects: by providing a positioning support 30 for supporting the chest and abdomen, a support point is provided for the chest and abdomen of the patient, which facilitates the positioning operation of medical staff and effectively enables the correct body position to be maintained for a long time without positioning deviation, thereby reducing the risk of thoracentesis surgery caused by the displacement of the thoracentesis positioning mark due to the patient's inability to maintain the correct body position for a long time during the existing thoracentesis process, thereby improving the accuracy and efficiency of the doctor's operation and the user experience of the patient; at the same time, by providing the width adjustment mechanism 11 and the first height adjustment mechanism 21, they can be flexibly adjusted according to the patient's body shape and comfort requirements, thereby improving the accuracy of thoracentesis and the patient's experience.
