The axis of the connection hole is along a first direction, and the first direction is the width direction of the medical transport vehicle; the medical drip rod includes a first drip rod and a second drip rod. Among them, the first drip rod and the second drip rod cross and are fixedly connected. The first drip rod is inserted into the connection hole and can rotate to a first position or a second position in the connection hole. The first position is the position of the first drip rod when the second drip rod is vertically arranged, and the second position is the position of the first drip rod when the second drip rod is horizontally arranged along the length direction of the medical transport vehicle; the medical locking assembly connects the medical connection seat and the first drip rod and locks the first drip rod in the first position or the second position.

[0008] Optionally, a first groove and a second groove are provided on the side surface of the first drip bottle rod. The center lines of the first groove and the second groove are perpendicular to each other and are arranged at intervals along the circumferential direction of the first drip bottle rod. The medical locking assembly includes a medical bolt and an elastic member. Among them, the medical bolt is slidably assembled on the medical connection seat and can slide between a third position and a fourth position. The third position is the position where one end of the medical bolt is embedded in the first groove or the second groove, and the fourth position is the position where one end of the medical bolt is located outside the first groove or the second groove. When the medical bolt is embedded in the first groove or the second groove, the rotation of the first drip bottle rod is restricted. One end of the elastic member contacts the medical connection seat, and the other end contacts the medical bolt. The elastic member exerts a force on the medical bolt to move from the fourth position to the third position.

[0009] Optionally, the elastic member is a compression spring. The medical bolt includes a bolt rod and a retaining ring. Among them, the retaining ring is sleeved outside the bolt rod and is fixedly connected to the bolt rod. The bolt rod is slidably assembled on the medical connection seat.

At this time, the second drip bottle rod is in a vertical state and can be used to hang the medicine bag. When it is necessary to move the patient on the bed, the medical locking assembly first releases the lock on the first drip bottle rod, rotates the first drip bottle rod to the second position, and then locks the first drip bottle rod with the medical locking assembly. At this time, the second drip bottle rod is located below the lower shelf and there is no obstruction above the bed, which is convenient for moving the patient on the medical transport vehicle.

[0016] When the medical plug is located in the first groove or the second groove, the side surface of the medical plug abuts against the side wall of the first groove or the second groove along the axial direction of the first infusion rod, thereby restricting the rotation of the first infusion rod around its own axis on the medical connector, so that the first infusion rod is locked in the first position or the second position.

[0017] When the first infusion rod rotates from the first position to the second position, the medical plug is inserted into the second groove. When the medical plug slides from the sixth position point towards the fifth position point and slides to the sixth position point, the second infusion rod moves towards the bed body until it moves below the lower shelf, thereby preventing the second infusion rod from protruding outside the lower shelf.

[0024] The special term "exemplary" here means "serving as an example, an embodiment or an illustration". Any embodiment described here as "exemplary" does not have to be construed as superior to or better than other embodiments. Although various aspects of the embodiments are shown in the drawings, the drawings do not have to be drawn to scale unless otherwise specified.

[0025] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0026] The embodiment of the present application discloses a medical transport vehicle, which is equipped with a medical bottle hanging rod. The medical bottle hanging rod can be used to hang an infusion belt and can be used to infuse patients on the medical transport vehicle, expanding the applicable scenarios of the medical transport vehicle, so that the medical transport vehicle can provide more functions and meet the treatment needs of more patients. However, the vertically arranged medical bottle hanging rod may sometimes affect the operation of transporting patients on the medical transport vehicle. The medical bottle hanging rod on the medical transport vehicle disclosed in the present application can be quickly placed horizontally under the bed surface when needed, so that the bed surface is free of obstacles, which is convenient for the operation of transporting patients.

[0027] For ease of description, a first direction, a second direction and a third direction are defined; wherein the first direction is the width direction of the medical transport vehicle, the second direction is the length direction of the medical transport vehicle, and the third direction is the height direction. The first direction and the second direction are both horizontally arranged. In the accompanying drawings, the first direction is represented as the X direction, the second direction is represented as the Y direction, and the third direction is represented as the Z direction.

[0028] Reference Figure 1 A medical transport vehicle includes a medical crossbeam 11, a medical bottle hanging rod 2 and a rod connecting mechanism, wherein the rod connecting mechanism includes a medical connecting seat 3 and a medical locking assembly 4.

[0029] The medical connection seat 3 is fixedly mounted on the medical crossbeam 11. The medical connection seat 3 is provided with a connection hole 31 for accommodating one end of the medical bottle rod 2. The axis of the connection hole 31 is along the first direction, which is the width direction of the medical transport vehicle.

[0030] Reference Figure 2 The medical bottle hanging rod 2 includes a first bottle hanging rod 21 and a second bottle hanging rod 22, wherein the first bottle hanging rod 21 and the second bottle hanging rod 22 are crossed and fixedly connected, the first bottle hanging rod 21 is inserted into the connecting hole 31, and can be rotated to a first position or a second position in the connecting hole 31, the first position is the position of the first bottle hanging rod 21 when the second bottle hanging rod 22 is vertically arranged, and the second position is the position of the first bottle hanging rod 21 when the second bottle hanging rod 22 is arranged horizontally along the length direction of the medical transport vehicle.

[0031] The medical locking assembly 4 connects the medical connecting seat 3 and the first bottle hanging rod 21, and locks the first bottle hanging rod 21 in the first position or the second position.

[0032] Specifically, the body of the medical transport vehicle includes a lower layer frame, an upper layer frame, vertical rods, a bed body, guardrails, and legs 12. There are four legs 12, which are fixed to the lower layer frame and used to support the lower layer frame. The upper layer frame is located above the lower layer frame, and the upper layer frame and the lower layer frame are fixedly connected by four vertical rods. The bed body is fixed to the upper layer frame and used to carry patients. There are two guardrails, which are located on both sides of the lower layer frame, and the guardrails are rotatably installed on the lower layer frame. The guardrails can be rotated above the lower layer frame or below the lower layer frame.

[0033] The lower layer frame includes a medical cross beam 11. The length of the medical cross beam 11 is set along the first direction. The medical connection seat 3 is fixedly installed on the medical cross beam 11. The connection method between the medical connection seat 3 and the medical cross beam 11 can be determined according to design requirements. In this embodiment, the medical connection seat 3 is welded to the medical cross beam 11. In another embodiment, the medical connection seat 3 can be fixedly connected to the medical connection seat 3 using a clamp.

[0034] It should be noted that the medical cross beam 11 represents the rod on the lower layer frame arranged along the first direction. In another embodiment, when the body structure of the medical transport vehicle changes, the medical cross beam 11 can be other fixed rods on the medical transport vehicle arranged along the first direction; the shape of the medical connection seat 3 is correspondingly deformed to avoid other components on the medical transport vehicle when fixedly connected to the medical cross beam 11.

[0035] A first hole is opened on the medical connection seat 3. The axis of the first hole is along the first direction. The first hole can completely penetrate the medical connection seat 3 along the first direction, or only penetrate one end of the medical connection seat 3 along the first direction.

[0036] The medical drip rod 2 includes a first drip rod 21 and a second drip rod 22. The first drip rod 21 is the horizontal part of the medical drip rod 2, and the second drip rod 22 is the part of the medical drip rod 2 that can be rotated to the horizontal position or the vertical position. The first drip rod 21 is inserted into the first hole. The outer diameter of the first drip rod 21 is equal to the diameter of the first hole, so that the first drip rod 21 can slide along the first direction in the first hole and can rotate around the center line of the first drip rod 21. The center line of the first drip rod 21 is arranged along the first direction. It should be noted that a retaining ring 412 is also provided on the first drip rod 21 to prevent the first drip rod 21 from sliding and separating from the first hole. The retaining ring 412 is not shown in the drawings.

[0037] When the first drip rod 21 rotates in the first hole, the second drip rod 22 rotates synchronously around the center line of the first drip rod 21. When the second drip rod 22 rotates to the vertical state and is located above the bed surface, the position of the first drip rod 21 is at the first position. See Figure 1; When the second infusion pole 22 rotates to a horizontal state and is arranged along the horizontal direction of the bed surface, at this time, the position of the first infusion pole 21 is at the second position. Refer to Figure 2 , attached Figure 3 and 4 The state when the first infusion pole 21 is at the second position is shown in.

[0038] The medical locking assembly 4 is used to lock the first infusion pole 21 at the first position or the second position. The medical locking assembly 4 can be the structural form described in the following content of this embodiment, or other existing components that can lock the first infusion pole 21 at the first position or the second position.

[0039] According to the usage requirements of the medical transport vehicle, when it is necessary to use the medical infusion pole 2 for infusion operation, rotate the first infusion pole 21 to the first position, and use the medical locking assembly 4 to lock and fix the first infusion pole 21 with the medical connection seat 3. At this time, the second infusion pole is in a vertical state and can be used to hang the medicine bag; when it is necessary to carry the patient on the bed, the medical locking assembly 4 first releases the lock on the first infusion pole 21, rotates the first infusion pole 21 to the second position, and then locks the first infusion pole 21 with the medical locking assembly 4. At this time, the second infusion pole is located below the lower layer shelf and there is no obstruction above the bed, which is convenient for carrying the patient on the medical transport vehicle.

[0040] The following content discloses a setting method of the medical locking assembly 4, and the medical locking assembly 4 locks the first infusion pole 21 at the first position or the second position.

[0041] Refer to Figure 3 and Figure 4 , as an alternative solution, the side surface of the first infusion pole 21 is provided with a first groove 211 and a second groove 212. The center lines of the first groove 211 and the second groove 212 are perpendicular to each other and are arranged at intervals along the circumferential direction of the first infusion pole 21.

[0042] Specifically, when the center line of the first groove 211 is along the second direction, the first infusion pole 21 is at the first position; when the center line of the second groove 212 is along the second direction, the first infusion pole 21 is at the second position. The first infusion pole 21 in the second position is schematically shown in the attached drawing. The center lines of the first groove 211 and the second groove 212 are the lines in the middle of the circumferential direction of the first groove 211 or the second groove 212 on the first infusion pole 21 and along the radial direction of the first infusion pole 21.

[0043] In this embodiment, neither end of the first groove 211 along the first direction penetrates the first infusion pole 21, and the depth of the first groove 211 is less than the radius of the first infusion pole 21.

[0044] The medical locking assembly 4 includes a medical bolt 41 and an elastic member 42. The medical bolt 41 is slidably assembled on the medical connector 3 and can slide between a third position and a fourth position. The third position is the position where one end of the medical bolt 41 is inserted into the first groove 211 or the second groove 212, and the fourth position is the position where one end of the medical bolt 41 is located outside the first groove 211 or the second groove 212. When the medical bolt 41 is inserted into the first groove 211 or the second groove 212, the rotation of the first drip rod 21 is restricted.

[0045] One end of the elastic member 42 contacts the medical connector 3, and the other end contacts the medical bolt 41. The elastic member 42 exerts a force on the medical bolt 41 to move it from the fourth position to the third position.

[0046] Specifically, the medical bolt 41 is slidably assembled on the medical connector 3 along the second direction, and a corresponding space is provided on the medical connector 3 to accommodate the sliding of the medical bolt 41.

[0047] The third position refers to the position where the medical bolt 41 is inserted into the first groove 211 or the second groove 212 and cannot continue to slide towards the first drip rod 21. Due to production errors and wear during use, the third position is not necessarily a fixed position. The fourth position refers to the position where the medical bolt 41 is removed from the first groove 211 or the second groove 212. At this time, the medical bolt 41 no longer restricts the rotation of the first drip rod 21.

[0048] The elastic member 42 is used to exert a force on the medical bolt 41. On the one hand, it pushes the medical bolt 41 to move from the fourth position towards the third position. On the other hand, it keeps the medical bolt 41 in the third position so that the medical bolt 41 contacts and presses against the side wall of the first groove 211. In this embodiment, the elastic member 42 uses a compression spring. In another embodiment, the elastic member 42 can be other components that exert a force on the medical bolt 41, such as a tension spring, a torsion spring, or an elastic sheet.

[0049] When the medical bolt 41 is located in the first groove 211 or the second groove 212, the side surface of the medical bolt 41 abuts against the side wall of the first groove 211 or the second groove 212 along the axial direction of the first drip rod 21, thereby restricting the rotation of the first drip rod 21 around its own axis on the medical connector 3, so that the first drip rod 21 is locked in the first position or the second position.

[0050] Refer to Figure 3 and Figure 4, as an alternative, the elastic member 42 is a compression spring. The medical plug 41 includes a plug rod 411 and a retaining ring 412; wherein, the retaining ring 412 is sleeved outside the plug rod 411 and fixedly connected to the plug rod 411; the plug rod 411 is slidably assembled on the medical connector 3, one end of the compression spring abuts against the medical connector 3, and the other end abuts against the retaining ring 412.

[0051] Specifically, the compression spring is arranged along the second direction. An installation space communicating with the first hole is formed on the medical connector 3. The installation space is horizontally arranged and corresponds to the first groove 211 on the first hanging rod 21 at the first position and the second groove 212 on the first hanging rod 21 at the second position.

[0052] The medical plug 41 and the elastic member 42 are located in the installation space. One end of the plug rod 411 is provided with a step. The retaining ring 412 is sleeved on the plug rod 411 and moves to the step position to contact and abut against the surface of the step. The compression spring is sleeved outside the plug rod 411, one end abuts against the end face of the retaining ring 412, and the other end abuts against the medical connector 3.

[0053] In this embodiment, the installation space includes a hole with the same outer diameter as the retaining ring 412 and a hole with the same diameter as the end of the plug rod 411 away from the first hanging rod 21.

[0054] Furthermore, the medical plug 41 further includes a lever 43. The lever 43 is arranged along the third direction, and both ends along the third direction are located outside the medical connector 3. One end of the plug rod 411 without the step passes through the installation space and extends outside the medical connector 3, and the end of the plug rod 411 passing through the medical connector 3 is threadedly connected to the lever 43.

[0055] The compression spring and the retaining ring 412 are sequentially placed into the installation space. One end of the plug rod 411 without the step passes through the retaining ring 412 and the compression spring and then extends outside the medical connector 3 from the installation space. The lever 43 is connected and fixed to the plug rod 411 to complete the installation of the medical locking assembly 4 on the medical connector 3.

[0056] By applying a force to the lever 43, the plug rod 411 can be driven to move. The retaining ring 412 applies a pressure to the compression spring, further compressing the compression spring, causing the medical plug 41 to move away from the first hanging rod, and the medical plug 41 is separated from the first groove or the second groove.

[0057] Refer to Figure 3 and Figure 4, as an alternative solution, when one end of the medical plug 41 is located in the second groove 212, the medical plug 41 is assembled on the second groove 212 by sliding in the first direction. The first drip rod 21 can slide to the fifth position point or the sixth position point on the medical connection seat 3 within the second groove 212. Among them, the sixth position point is closer to the second drip rod 22 than the fifth position point.

[0058] Specifically, the length of the second groove 212 in the first direction is greater than the dimension of the medical plug 41 in the first direction. When the medical plug 41 is located within the second groove 212, the medical plug 41 restricts the rotation of the first drip rod 21, but the first drip rod 21 can slide in the first direction, and the sliding range is between the positions where the two side walls of the second groove 212 in the first direction contact the medical plug 41. In this embodiment, when the two side walls of the second groove 212 in the first direction contact the medical plug 41, the two positions on the medical connection seat 3 are the fifth position point and the sixth position point respectively.

[0059] When the first drip rod 21 rotates from the first position to the second position, the medical plug 41 is inserted into the second groove 212. When the medical plug 41 slides from the sixth position point towards the fifth position point and slides to the sixth position point, the second drip rod 22 moves closer to the bed body until it moves below the lower shelf, thereby preventing the second drip rod 22 from protruding outside the lower shelf.

[0060] It should be noted that on the one hand, the second drip rod 22 is a structural avoidance leg 12 as described below, and on the other hand, both the second drip rod 22 and the first drip rod 21 are arranged between the two legs 12 on the same side of the bed body.

[0061] Refer to Figure 3 and Figure 4 , as an alternative solution, a locking groove 213 is provided on the side surface of the first drip rod 21.

[0062] A spring buckle piece 32 is fixed on the medical connection seat 3. The spring buckle piece 32 is arranged at the sixth position point and is used to engage with the locking groove 213 on the first drip rod 21 at the second position.

[0063] Specifically, the locking groove 213 is set as an arc-shaped groove in this embodiment. In another embodiment, the locking groove 213 can be a cylindrical groove.

[0064] The snap tab 32 is installed on the medical connector 3. There is an arc-shaped protrusion on the snap tab 32. When the arc-shaped protrusion is inserted into the locking groove 213, it engages with the first infusion rod 21, thereby preventing the first infusion rod 21 from sliding in the first direction. When the force applied to the first infusion rod 21 gradually increases, the side wall of the locking groove 213 applies pressure to the arc-shaped protrusion, causing the snap tab 32 to deform. As the force applied to the first infusion rod 21 increases to a set size, the arc-shaped protrusion moves out of the locking groove 213. At this time, the first infusion rod 21 can freely slide in the first direction within the second groove 212.

[0065] Further, the two side walls of the first groove 211 along the first direction are flush with the two side walls of the second groove 212 along the first direction one by one. When one end of the medical plug 41 is located in the first groove 211, the medical plug 41 is assembled on the first groove 211 by sliding along the first direction. The first infusion rod 21 can slide to the fifth position point or the sixth position point 2 on the medical connector 3 within the first groove 211.

[0066] There are two snap tabs 32 in total, and the two snap tabs 32 are respectively arranged at the fifth position point or the sixth position point.

[0067] Referring to Figure 2 , as an alternative solution, an arc-shaped portion 221 for avoiding the leg 12 is provided on the second infusion rod 22.

[0068] Specifically, when the second infusion rod 22 rotates to the horizontal position, the arc-shaped portion 221 on the second infusion rod 22 corresponds to the leg 12, thereby avoiding the leg 12, so that most of the second infusion rod 22 can be located below the lower shelf, reducing the portion of the second infusion rod 22 outside the lower shelf.

[0069] Referring to Figure 4 , as an alternative solution, the first groove 211 and the second groove 212 are flared grooves. One end of the medical plug 41 facing the first infusion rod 21 is a tapered end.

[0070] Specifically, the cross-sections of both the first groove 211 and the second groove 212 are trapezoidal. One end of the medical plug 41 provided with a step is a tapered end, and the taper of the tapered end matches the cross-sections of the first groove 211 and the second groove 212.

[0071] In another embodiment, the first groove 211 and the second groove 212 are flared grooves, and the end of the medical plug 41 is a cylindrical end. In another embodiment, the first groove 211 and the second groove 212 are square grooves, and the end of the medical plug 41 is a tapered end.

[0072] When the first groove 211 and the second groove 212 are arranged as flared groove structures, the medical plug 41 is convenient to be inserted into the first groove 211 or the second groove 212; when the medical plug 41 has a tapered end, the medical plug 41 is convenient to be inserted into the first groove 211 or the second groove 212.

[0073] Referring to Figure 2 , as an alternative, the second drip rod 22 is a telescopic rod. One end of the second drip rod 22 is fixedly connected to the first drip rod 21, and the other end is provided with a hook 23 for hanging the medicine bag.

[0074] Specifically, one end of the second drip rod 22 is fixed to the first drip rod 21, and the distance between the other end and the first drip rod 21 is different when the second drip rod 22 extends or retracts. Specifically, the second drip rod 22 includes a first tube and a second tube. The first tube is fixedly connected to the first drip rod 21. One end of the second tube is inserted into the first tube. The second tube is provided with a spring buckle piece, and two holes are arranged on the first tube at intervals along its length direction, and the two holes can correspond to the spring buckle piece.

[0075] It should be noted that when the second drip rod 22 is provided with an arc portion 221, the arc portion 221 is arranged on the first tube, and there is a gap between the position of the second tube on the first tube and the arc portion 221.

[0076] The second drip rod 22 is a telescopic rod. The height of the hook 23 can be adjusted by extending or retracting the second drip rod 22, so that the medicine bag can be hung at different height positions.

[0077] Furthermore, the hook 23 can rotate relative to the second drip rod 22. When the second drip rod 22 is in a horizontal position, the hook 23 can be rotated under the bed body to prevent the hook 23 from protruding from the lower shelf.
