Example (b):
referring to fig. 1 and 2, the present embodiment provides an examination apparatus 100 for pain department, which includes a support frame 110 and a pressing rod 120, wherein the support frame 110 is used for mounting the pressing rod 120 and is fixedly connected with a hospital bed. The support frame 110 comprises a first connecting rod 111 and a second connecting rod 112, wherein the first connecting rod 111 and the second connecting rod 112 are horizontally arranged, and the first connecting rod 111 and the second connecting rod 112 are connected through a middle connecting rod 113 to form an L shape. The end of the first connecting rod 111 is provided with a horizontal installation shaft, the middle of the pressing rod 120 is rotatably connected with the installation shaft, and the pressing rod 120 can be rotated in a holding manner to press the body of the patient by the pressing end of the pressing rod 120.
With continued reference to fig. 1, the middle connecting rod 113 includes a horizontal portion and a vertical portion which are vertically connected, the first connecting rod 111 is telescopically connected with the horizontal portion, and the second connecting rod 112 is telescopically connected with the vertical portion. Specifically, the middle connecting rod 113 is a tubular structure with a slightly larger cross-sectional dimension, the first connecting rod 111 is inserted in the horizontal portion thereof, and the second connecting rod 112 is inserted in the vertical portion thereof; threaded holes are formed in both ends of the middle connecting rod 113, a screw is arranged in each threaded hole, and after the screws are tightened, the positions of the first connecting rod 111 and the second connecting rod 112 relative to the middle connecting rod 113 are fixed.
The position of the pressing rod 120 in the horizontal direction can be adjusted by adjusting the extension length of the first connecting rod 111; the position of the pressing lever 120 in the vertical direction is adjusted by adjusting the protruding length of the second connecting rod 112. In addition, the lower end of the second connecting rod 112 is further provided with a cylindrical mounting post (not shown), the edge of the hospital bed (not shown) is vertically provided with a mounting tube, the mounting post is inserted into the mounting tube, and when the mounting post rotates around the axis of the mounting post, the first connecting rod 111 and the second connecting rod 112 can synchronously rotate, so that the position of the pressing rod 120 on the horizontal plane can be adjusted. The wall of the mounting cylinder is provided with a threaded hole, a screw is mounted in the threaded hole, and after the screw is screwed down, the end part of the screw is abutted against the mounting column to fix the mounting column in the mounting cylinder. The above design enables the position of the pressing rod 120 to be adjusted in a three-dimensional space, thereby facilitating the examination of the suspected lesion site of the patient.
Further, in order to improve the overall strength and rigidity of the support bracket 110, the deformation amount thereof is reduced; in this embodiment, the first connecting rod 111 and the second connecting rod 112 both adopt a rectangular cylinder structure.
A connecting pin 1112 is vertically arranged at the end part of the first connecting rod 111, and the mounting shaft is horizontally arranged and fixedly connected with the end part of the connecting pin 1112; the middle portion of the pressing bar 120 is rotatably coupled to the mounting shaft, and the pressing bar 120 is located substantially in the same vertical plane as the first connecting bar 111. The design makes the middle part of the pressing rod 120 and the first connecting rod 111 form a certain distance, so that the pressing rod 120 can rotate in a certain angle when the first connecting rod 111 and the pressing rod 120 are held; thereby being capable of pressing the body of the patient.
The pressing rod 120 includes a holding section 122 and a pressing section 121 connected to each other, wherein the holding section 122 is located below the first connecting rod 111, the pressing section 121 extends outward, and an end portion thereof is a thumb-shaped pressing end.
Further, with reference to fig. 1, the inspection apparatus 100 further includes a pressure detecting assembly 130, which includes a pressure sensor 131 and a compression spring 132, wherein the pressure sensor 131 is disposed at the bottom of the first connecting rod 111, and one end of the compression spring 132 is connected to the pressure sensor 131, and the other end is connected to the upper portion of the holding section 122. The moment arm from the position where the compression spring 132 is connected with the grip section 122 to the mounting shaft is equal to the moment arm from the pressing end to the mounting shaft, so that the forces at the two positions are equal. When the grip section 122 is gripped, the grip section 122 presses the compression spring 132, and the elastic force of the compression spring acts on the pressure sensor 131; at this time, the pressure sensor 131 can detect the holding force of the holding section 122, which is approximately equal to the force applied to the patient by the pressing end. The pressure detecting component 130 can record the pressing force when the patient feels pain, so as to provide data support for the pathological degree; when the patient feels pain with a small pressing force, the degree of the lesion is serious, and conversely, the degree of the lesion is slight.
Referring to fig. 3-5, the pressing rod 120 further includes a pressing section connecting cylinder 123 and a holding section connecting cylinder 124, and the pressing section connecting cylinder 123 and the holding section connecting cylinder 124 are coaxially disposed and both rotatably sleeved on the mounting shaft. The pressing section 121 is fixedly connected with the cylinder wall of the pressing section connecting cylinder 123, and the holding section 122 is fixedly connected with the cylinder wall of the holding section connecting cylinder 124; thereby enabling the pressing section 121 and the pressing section connecting cylinder 123 to rotate synchronously, and the grip section 122 and the grip section connecting cylinder 124 to rotate synchronously.
Further, referring to fig. 6, a first engaging groove 1231 is disposed on the pressing section connecting cylinder 123, and a second engaging groove 1241 is disposed on the holding section connecting cylinder 124; the first clamping groove 1231 and the second clamping groove 1241 are respectively located on one side of the pressing section connecting cylinder 123 adjacent to the holding section connecting cylinder 124, so that when the holding section connecting cylinder 124 rotates, the first clamping groove 1231 can be communicated with the second clamping groove 1241.
In order to restrict the relative rotation of the pressing section connecting cylinder 123 and the grip section connecting cylinder 124, the inspection apparatus 100 further includes a locking lever 140 and a rotating portion, wherein one end of the locking lever 140 is provided with a locking hook 141, and the other end is rotatably connected to the grip section 122 through the rotating connecting portion 150. Specifically, a pin shaft is horizontally arranged on one side of the holding section 122, the rotating connecting part 150 is provided with a mounting hole, and the rotating connecting part 150 is sleeved on the pin shaft and can freely rotate around the pin shaft; the locking lever 140 is fixedly connected to the rotary connection portion 150, and when the locking lever 140 swings within a certain angle range, the locking hook 141 can be simultaneously snapped into the first latching groove 1231 and the second latching groove 1241, so that the relative positions of the pressing section connecting cylinder 123 and the holding section connecting cylinder 124 are locked. That is, the locking hook 141 has a wide width in the axial direction of the two connector barrels, and when the notches of the first and second locking grooves 1231 and 1241 correspond, the locking hook 141 can be simultaneously locked into the first and second locking grooves 1231 and 1241, so that the relative rotation between the two connector barrels is restricted; at this time, the two connecting cylinders can synchronously rotate around the mounting shaft. When the locking lever 140 is rotated reversely, the locking hook 141 can be disengaged from the first and second locking grooves 1231 and 1241, so that the two connecting cylinders can be rotated relatively. When the two connection cylinders are locked, a gripping force can be applied to the end of the pressing section 121 using the principle of leverage by gripping the gripping section 122, thereby pressing the body of the patient. When the two connector barrels are unlocked, the gripping force of the gripping section 122 is not transmitted to the pressing section 121.
Optionally, a magnet may be further disposed at an end of the locking hook 141, so that the locking hook 141 can be reliably coupled with the two connecting cylinders in an attraction manner; preventing the locking hooks 141 from falling out of the two card slots.
When a patient feels pain, the two connecting cylinders can be unlocked firstly, at the moment, the holding force of the holding section 122 is kept unchanged, and after the data displayed on the display screen is recorded, the holding section 122 is loosened. The above design can reduce the pain of the patient being pressed during the period of recording data, and can also give sufficient time for recording data.
Further, in order to facilitate a person to operate and record data, the inspection apparatus 100 is further provided with a fixing rod 160 and an operating rod 170; wherein, one end of the fixing rod 160 is provided with a fixing hook 161, and the other end is fixedly connected with the rotary connecting part 150; the fixing lever 160 serves to restrict rotation between the pressing section connecting cylinder 123 and the mounting shaft. The operating rod 170 is fixedly connected to the rotation connecting portion 150 and is disposed at one side of the grip section 122. When the doctor grips the grip section 122, since the operation lever 170 can drive the fixing lever 160 and the locking lever 140 to rotate synchronously by rotating the connection portion 150, if the patient feels pain, the doctor can unlock the two connection cylinders by directly pulling the operation lever 170, and the fixing hook 161 of the fixing lever 160 fixes the grip section connection cylinder 124 to prevent the rotation thereof. At this time, the doctor may release the grip section 122 and the data detected by the pressure sensor 131 remains unchanged, so that one doctor can complete the examination and recording work.
Specifically, with continued reference to fig. 4 and 5, the cylinder wall of the holding connecting cylinder 124 is provided with a fixing clip hole 1232, and the circumferential surface of the mounting shaft 190 is uniformly provided with a plurality of fixing grooves 191; the fixing groove 191 extends in the axial direction of the mounting shaft. When the fixing lever 160 swings, the fixing hook 161 at the end thereof can pass through the fixing clip hole 1232 and be clipped into the corresponding fixing groove on the mounting shaft. At this time, the rotation between the grip section connecting cylinder 124 and the mounting shaft is restricted; that is, when the surgeon releases his hand, the grip section 122 will not rotate and will remain in place. The compression spring 132 can apply a certain elastic force to the grip section 122, which generates a large frictional force between the fixing hook 161 and the fixing groove 191 on the mounting shaft, thereby preventing the fixing hook 161 from being released. In addition, a magnet may be provided at an end of the fixing hook 161, thereby further improving reliability of engagement between the fixing hook 161 and the fixing groove.
In addition, the fixing rod 160, the locking rod 140 and the operating rod 170 are all fixedly connected to the rotating connection portion 150, and an included angle between the fixing rod 160 and the locking rod 140 is set, so that when the fixing hook 161 is snapped into the fixing groove, the locking hook 141 is separated from the first latching groove 1231 and the second latching groove 1241, and when the locking hook 141 is snapped into the first latching groove 1231 and the second latching groove 1241, the fixing hook 161 is separated from the fixing latching hole 1232. Accordingly, the fixing hook 161 can pass through the fixing hole of the pressing section connecting cylinder and be snapped into the corresponding fixing groove while the locking hook 141 is disengaged from the two catching grooves by rotating the operating lever 170. That is, the grip piece 122 can be fixed while the push piece 121 is unlocked.
Optionally, the holding section connecting cylinder 124 includes a first portion and a second portion coaxially disposed, and the pressing section connecting cylinder 123 is disposed between the first portion and the second portion, so that when the holding section 122 drives the holding section connecting cylinder 124 to rotate, the mounting shaft is not subjected to an additional bending moment. In order to connect the grip section 122 with the grip section connecting cylinder 124, a connecting piece 180 is further provided; the connecting member 180 is a U-shaped rod structure, two ends of the connecting member 180 are respectively connected to the first portion and the second portion, and the holding section 122 is connected to the connecting member 180.
