Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a top pressing device for checking premature infants. Background Art

[0002] Retinopathy of prematurity (ROP) is a retinal vascular proliferative disease that occurs in premature infants and low birth weight infants. The non-vascularized retina undergoes fibroangiomatosis and contraction, which further causes tractional retinal detachment and blindness. It was previously called Terry syndrome or retrolental fibroplasia, but the latter only reflects the late manifestation of the disease. The incidence rate can reach 60% to 80% in those with shorter gestational age or lower birth weight.

[0003] The method of fully dilating the pupil, opening the eyelids with an eyelid speculum, and binocular indirect ophthalmoscope combined with scleral pressure is considered the "gold standard" for ROP screening internationally.

[0004] In the prior art, the pressing part of the pressure device is usually spherical and is relatively large for premature infants, making it not suitable for scleral pressure on premature infants. In addition, the angle between the pressure top and the handle is fixed, making it inconvenient to adjust the pressure height. In view of the above problems, a pressure device for premature infant examination is proposed. Utility Model Content

[0005] The utility model aims to provide a top pressing device for premature infant examination, so as to solve the problems that the existing top pressing device is too large for premature infants, the angle between the top pressing portion and the handle is fixed, and the top pressing height is inconvenient to adjust.

[0006] In order to achieve the above object, the utility model provides the following technical solutions:

[0007] A pressure device for examining premature infants comprises a pressure top portion, a rotating rod, a handle and a hinged portion. The pressure top portion is an elliptical ring fixed to one end of the rotating rod. The end of the rotating rod away from the pressure top portion is connected to one end of the handle through a hinged portion. The rotating rod can adjust its angle by rotating the hinged portion relative to the handle.

[0008] Furthermore, the hinged part includes a first joint, a second joint and a screw, the first joint is arranged at the end of the rotating rod away from the pressing top, the second joint is arranged at one end of the handle, the screw is provided with an external thread, and the second joint is provided with an internal thread. The screw and the second joint cooperate with each other through the internal and external threads to clamp the first joint tightly and lock the angle.

[0009] Furthermore, friction lines are arranged on the friction surface between the first joint and the second joint.

[0010] Furthermore, the friction pattern is sawtooth-shaped.

[0011] Furthermore, the gripping portion of the screw is a butterfly-wing-shaped gripping portion.

[0012] Furthermore, the handle is provided with a knurled pattern.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The pressure top is an elliptical ring. Compared with the spherical pressure top in the prior art, it has a smaller volume and a larger contact area with the sclera, and is more suitable for scleral pressure tops in premature infants.

[0015] 2. The angle between the top of the sclera and the handle can be adjusted by rotating the rod, which is convenient for medical staff to adjust the height of the sclera sclera sclera. It is suitable for a variety of sclera ... BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples:

[0022] like Figure 1-3 As shown, a pressure device for premature infant examination includes a pressure top portion 1, a rotating rod 2, a handle 3 and a hinged portion 4. The pressure top portion 1 is an elliptical ring, fixed to one end of the rotating rod 2, and the end of the rotating rod 2 away from the pressure top portion 1 is connected to one end of the handle 3 through the hinged portion 4. The rotating rod 2 can be rotated relative to the handle 3 through the hinged portion 4 to adjust the angle. Compared with the spherical pressure top portion 1 in the prior art, the elliptical ring-shaped pressure top portion 1 is smaller in size, more suitable for premature infants, has a larger contact area, and is not easy to slip. The angle between the rotating rod 2 and the handle 3 can be adjusted through the hinged portion 4, so that the pressure top portion 1 presents working postures at different angles, which is convenient for medical staff to adjust the pressure top height and is suitable for a variety of scleral pressure top operation techniques.

[0023] The hinged part 4 includes a first joint 401, a second joint 402 and a screw pin 403. The first joint 401 is arranged at the end of the rotating rod 2 away from the pressing top part 1, and the second joint 402 is arranged at one end of the handle 3. The screw pin 403 is provided with an external thread, and the second joint 402 is provided with an internal thread. The screw pin 403 and the second joint 402 cooperate with each other through the internal and external threads to clamp the first joint 401 tightly and lock the angle. By tightening the screw pin 403, the screw pin 403 is screwed into the second joint 402, and the first joint 401 is clamped between the screw pin 403 and the second joint 402. The friction force generated by the clamping locks the angle between the rotating rod 2 and the handle 3. When the screw pin 403 is loosened, a certain gap is left between the screw pin 403 and the second joint 402, so that the first joint 401 can move. At this time, the angle of the rotating rod 2 relative to the handle 3 can be adjusted. In addition, in order to facilitate medical staff to rotate the screw pin 403, the gripping part of the screw pin 403 is a butterfly-shaped gripping part 4031.

[0024] The friction surface between the first joint 401 and the second joint 402 is provided with a friction pattern 5. The friction pattern 5 is sawtooth-shaped, and the sawtooth-shaped friction pattern 5 increases the roughness of the friction surface between the first joint 401 and the second joint 402, so as to make the angle locking more stable.

[0025] The handle 3 is provided with a knurled pattern 301 to prevent slipping. The knurled pattern 301 on the handle 3 prevents medical personnel from slipping when holding the handle.

[0026] The utility model has a simple structure and is easy to operate. The elliptical ring-shaped pressing top portion 1 is more suitable for scleral pressing of premature infants. The angle between the rotating rod 2 and the handle 3 is adjusted through the hinge portion 4, so that the pressing top portion 1 presents working postures at different angles, which is convenient for medical staff to adjust the pressing height. The utility model is suitable for a variety of scleral pressing operation techniques and is suitable for popularization and use.

[0027] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
