Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a blood sampling stand capable of actively adjusting posture. Background Art

[0002] When drawing blood from a vein, the person being drawn usually needs to lay their arm flat on the table, tie a tourniquet above the cubital fossa, and then select the most suitable median cubital vein to take the blood collection needle. However, in the actual blood collection process, the cubital fossa is often passively bent due to the different heights and arm lengths of the person being drawn. Therefore, some medical institutions will place a blood collection stand on the blood collection table, use the blood collection stand to support the patient's arm, and adjust the blood collection stand to ensure that the arm being drawn is straight.

[0003] Among them, the adjustment method of the blood collection stand is usually aimed at the front and rear sections of the blood collection stand, that is, the two sections that support the forearm and the back arm. By raising and lowering the height of these two ends, the whole reaches a straight level, thereby driving the arm to passively remain straight.

[0004] However, this two-stage adjustment requires the front and rear sections to adapt to each other and form a straight line to achieve the straightening purpose. This is difficult to operate during specific use, so more operating steps are required, which ultimately makes the overall process more inconvenient. Utility Model Content

[0005] The utility model aims to provide a blood sampling stand with active posture adjustment, so as to solve the technical problem in the prior art that the operation is relatively complicated due to the two-stage straightening method coordinated with each other.

[0006] In order to solve the above technical problems, the utility model specifically provides the following technical solutions:

[0007] A blood sampling stand with active posture adjustment comprises a bottom base, a fulcrum rod body is arranged on the bottom base, and the end of the fulcrum rod body is rotatably connected to a semicircular stand;

[0008] The semicircular stand includes an elbow fossa section, which is arranged in the middle of the semicircular stand and directly above the fulcrum rod body, and the two ends of the elbow fossa section are respectively provided with a forearm section and a rear arm section, and an arc section fixer is arranged at the bottom of the forearm section of the semicircular stand;

[0009] The arc segment fixer includes a first truncated body and a second truncated body, wherein the first truncated body and the second truncated body are fixedly connected to the semicircular stand and the bottom base respectively, and the first truncated body is slidably arranged inside the second truncated body, and a fixing key for fixing the sliding position of the first truncated body is arranged outside the second truncated body.

[0010] As a preferred solution of the utility model, the elbow fossa section includes an elbow fossa gasket, which is arranged directly above the fulcrum rod body, and the elbow fossa gasket is connected to a longitudinal extension connecting rod structure, and the longitudinal extension connecting rod structure is used to drive the elbow fossa gasket to rise and fall vertically.

[0011] As a preferred solution of the utility model, the longitudinal extension connecting rod structure includes two connecting rods, each of which has one end rotatably mounted on the bottom of the elbow pad, and the other end rotatably mounted on two nodes, the two nodes are respectively slidably arranged on the front arm section and the rear arm section, and the two nodes are connected to the transverse movement structure, and the transverse movement structure drives the two nodes to move toward or away from each other to push the elbow pad to rise or fall.

[0012] As a preferred solution of the utility model, the transverse movement structure includes a screw rod, which is axially rotatably installed in the semicircular stand, and the screw rod is connected to the two node devices through two sections of threads in opposite directions.

[0013] As a preferred solution of the utility model, the bottom base includes an upper base and a lower base, the second section is arranged on the upper base, the upper base is connected to the lower base through an electric telescopic rod, a circuit element for driving the electric telescopic rod to extend and retract is arranged inside the lower base, and a button is arranged on the surface of the lower base.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model forms a lever structure through the fulcrum rod body and the semicircular stand. After the patient's elbow, forearm and hind arm are placed in corresponding positions, the forearm is naturally lowered, and the semicircular stand rotates around the fulcrum rod body as a whole, forming an action process in which the forearm section falls and the hind arm section rises, thereby automatically making the whole arm reach a fully straightened state. Not only is the operation process simple and quick, but the straight state of the elbow fossa is also optimal.

[0016] In addition, the device is also provided with a longitudinal extension connecting rod structure, which assists patients who are unable to straighten their arms independently or need to straighten their arms slowly to achieve a straight arm state by lifting the elbow socket, thereby extending the practical range of the device.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0024] like Figure 1 to Figure 2 As shown, the utility model provides a blood sampling stand with active posture adjustment, including a bottom base 1, a fulcrum rod body 2 is arranged on the bottom base 1, and the end of the fulcrum rod body 2 is rotatably connected to a semicircular stand 3 to form a lever structure. The semicircular stand 3 includes an elbow fossa section 31, which is arranged in the middle of the semicircular stand 3 and directly above the fulcrum rod body 2, and the two ends of the elbow fossa section 31 are respectively provided with a forearm section 32 and a rear arm section 33. The semicircular stand 3 is located at the bottom of the forearm section 32 and an arc section fixer 4 is arranged. Therefore, when the patient's elbow fossa is placed at the position where the semicircular stand 3 is located at the top of the fulcrum rod body 2, the forearm and the rear arm are placed on the forearm section 32 and the rear arm section 33 respectively. At this time, if the patient rises higher, the distance between his shoulder and the table surface is large, then his rear arm will not fit with the rear arm section of the semicircular stand 3, forming an angle, and at the same time, an elbow fossa will be formed, which is not conducive to puncture and blood collection. At this time, relax the arm, unlock the arc segment fixer 4, and let the forearm droop automatically, which will drive the forearm segment 32 to fall, so that the semicircular stand 3 as a whole rotates around the end of the fulcrum rod body 2, and the rear arm segment rises and fits with the patient's rear arm, automatically forming a straight state of the arm, thereby achieving a state that can be punctured.

[0025] Furthermore, the arc segment fixer 4 includes a first truncated body 41 and a second truncated body 42, which are fixedly connected to the semicircular stand 3 and the bottom base 1 respectively, and the first truncated body 41 is slidably arranged inside the second truncated body 42, and a fixed key 43 for fixing the sliding position of the first truncated body 41 is arranged outside the second truncated body 42.

[0026] The arc-shaped arc segment fixer 4 can facilitate its telescopic sliding. When the semicircular stand 3 is tilted at a suitable angle so that the arm is straightened, the fixing piece is pressed to fix the position of the first section 41, so that the semicircular stand 3 will not rotate, and it is convenient to perform puncture. The fixing piece can be a bolt, and the first section 41 is fixed by screwing the bolt into the second section 42.

[0027] Furthermore, when some patients, such as those with insufficient muscle strength or muscle strain, are unable to straighten their arms voluntarily or need to slowly and adaptively straighten their arms, if they directly use the aforementioned lever structure to straighten their arms, they may suffer from secondary strain and other problems due to excessive forearm descent and too rapid straightening process.

[0028] Therefore, the elbow fossa section 31 in the present device includes an elbow fossa gasket 5, which is arranged directly above the fulcrum rod body 2, and the elbow fossa gasket 5 is connected to a longitudinal connecting rod structure, which is used to drive the elbow fossa gasket 5 to rise and fall vertically.

[0029] like Figure 2 As shown, the longitudinal connecting rod structure includes two connecting rods 6, one end of the two connecting rods 6 is rotatably mounted on the bottom of the elbow pad 5, and the other end is rotatably mounted on two node devices 7. The two node devices 7 are respectively slidably set on the front arm section 32 and the rear arm section, and the two node devices 7 are connected to the transverse movement structure. The transverse movement structure drives the two node devices 7 to move toward or away from each other to push the elbow pad 5 to rise or fall.

[0030] The transverse movement structure includes a screw rod 8, which is axially rotatably installed in the semicircular stand 3, and the screw rod 8 is connected to two nodes 7 through two sections of threads in opposite directions.

[0031] The cubital fossa pad 5 is lifted by controlling the transverse movement structure, and the lifting speed of the cubital fossa pad 5 is controlled autonomously, so that the arm can be slowly straightened with stronger adaptability to achieve a safe and stable effect.

[0032] Specifically, the elbow fossa gasket 5 can be flush with the inner wall of the semicircular stand 3 during actual production, one end of the screw rod 8 is rotatably mounted on the semicircular stand 3, and the other end is extended outwardly and connected with a screw plate. When the screw rod 8 is rotated, since the two ends of the screw rod 8 have opposite thread directions, the two nodes 7 (nuts can be used during actual production) thereon move in opposite directions on the screw rod 8, and since the elbow fossa gasket 5 limits the connecting rod 6, the node 7 can only move axially in opposite directions on the screw rod 8, so it can drive the other end of the connecting rod 6 to rise and fall, and then drive the elbow fossa gasket 5 connected to this end to rise and fall, so that the rise and fall of the elbow fossa can be controlled autonomously. When the elbow fossa rises, the forearm naturally droops according to the gravity factor, thereby reaching a straight state.

[0033] Furthermore, the bottom base 1 includes an upper base 9 and a lower base 10, the second section 42 is arranged on the upper base 9, the upper base 9 is connected to the lower base 10 through an electric telescopic rod 11, and a circuit element for driving the electric telescopic rod 11 to extend and retract is arranged inside the lower base 10, and a button is arranged on the surface of the lower base 10.

[0034] The arrangement of the electric telescopic rod 11 can drive the entire device to rise and fall, thereby adapting to patients of different body shapes and heights, making the device more flexible.

[0035] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
