[0031] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0032] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

[0033] like Figures 1 to 8 As shown, the dressing changing machine of the present application includes a base 3, to which a clamping shell 1 is rotatably connected. Specifically, a rotating slide 31 is formed on the base 3, and the rotating slide 31 extends along the circumference of the base 3. The clamping shell 1 and the rotating slide 31 are rotatably connected, and the clamping shell 1 rotates along the circumference of the base 3. A plurality of clamping holes 10 are formed in the clamping shell 1, and a pair of bottle mouth clamping sliders 2 for clamping an infusion bottle are provided in any of the clamping holes 10. An infusion needle 4 is provided on the base 3. The clamping shell 1 rotates relative to the base 3 to drive the infusion bottle to move above the infusion needle 4. A manipulator 41 is also provided on the base 3, and an anti-slip component 42 is provided on the manipulator 41. The anti-slip component 42 is used to fix the infusion needle 4 on the manipulator 31.

[0034] In this embodiment, the infusion bottle or bag is placed upside down on the clamping housing 1, and the bottle mouth of the infusion bottle or bag is inserted into the clamping hole 10. The rotation of the clamping housing 1 enables different infusion bottles or bags to be moved above the infusion needle 4, so that the infusion needle 4 can be easily connected to different infusion bottles or bags during infusion.

[0035] It is worth noting that in this embodiment, the clamping housing 1 is provided with four clamping holes 10. Two adjacent clamping holes 10 can be respectively inserted into different infusion bottles and infusion bags, thereby maintaining the stability of the infusion bottles and infusion bags in the clamping housing 1 by virtue of the support effect between the adjacent infusion bottles and infusion bags. Accordingly, infusion bags can also be inserted into all four clamping holes 10, which can also play a corresponding supporting role.

[0036] A clamping groove 13 is formed on the side of the clamping hole 10, extending radially along the clamping hole 10. The clamping slider 2 is slidably connected to the clamping groove 13, and the clamping slider 2 slides toward and away from the clamping hole 10 along the clamping groove 13. A first elastic member 20 is also included. The clamping slider 2 is connected to one end of the first elastic member 20, and the other end of the first elastic member 20 is connected to the clamping groove 13. The first elastic member 20 drives the clamping slider 2 to slide toward the clamping hole 10. The bottle mouth of the infusion bottle can be released by pushing the clamping slider 2 to both sides. After release, the clamping slider 2 is reset under the action of the first elastic member 20.

[0037] In another embodiment, a pressing rod 5 may also be included. A first inclined surface 23 is formed on the surface of the clamping slider 2. By pressing a push button 50 provided on the pressing rod 5, the pressing rod 5 slides downward along the first inclined surface 23, thereby driving the clamping slider 2 to slide away from the clamping hole 10. Specifically, the first inclined surface 23 is located on opposite sides of the clamping slider 2. When the pressing rod 5 slides downward along the first inclined surface 23, the two opposing clamping sliders 2 simultaneously move away from each other, thereby releasing the bottle mouth of the infusion bottle. The simultaneous action of the pressing rod 5 on the two clamping sliders 2 helps reduce the workload of medical personnel.

[0038] In other embodiments, a lifting motor 6 may be further included, wherein the body of the lifting motor 6 is connected to the clamping housing 1, and the output end of the lifting motor 6 is connected to the pressing rod 5, and the lifting motor 6 drives the pressing rod 5 to rise and fall. The driving action of the lifting motor 6 can realize the automatic raising and lowering of the pressing rod 5, which is conducive to further reducing the workload of medical workers.

[0039] Each clamping slider 2 includes a first clamping portion 21 and a second clamping portion 22, and a first hole 11 and a second hole 12 are formed in the clamping housing 1. The clamping hole 10 connects the first hole 11 and the second hole 12, and the axis of the clamping hole 10 coincides with the first hole 11 and the axis of the clamping hole 10 coincides with the second hole 12.

[0040] It is easy to understand that the mouth of the infusion bottle 100 passes through the first clamping part 21, the second clamping part 22, the first hole body 11 and the second hole body 12 from top to bottom, and the mouth of the infusion bottle 100 is clamped by the first clamping part 21, the second clamping part 22, the first hole body 11 and the second hole body 12.

[0041] The first clamping portion 21 is formed by extending outward from the side of the clamping slider 2. The first clamping portion 21 has a lower surface for securing the bottle mouth. The two first clamping portions 21 secure the bottle mouth from both sides. Specifically, the first clamping portion 21 can press against the side of the bottle mouth from both sides, and the first clamping portion 21 can also press against the upper end surface of the bottle mouth. The second clamping portion 22 is formed by the side of the clamping slider 2. The two second clamping portions 22 secure the bottle mouth from both sides, that is, the second clamping portions 22 press against the side of the bottle mouth from both sides.

[0042] The first hole 11 is provided on the bottom surface of the clamping shell 1, and the first hole 11 has an inner surface for radially securing the bottle mouth. Specifically, the inner surface of the first hole 11 can secure the bottle mouth in a radial direction. A gap is provided between the upper end surface of the first hole 11 and the bottle mouth. The second hole 12 is provided through the bottom surface of the clamping shell 1, and the second hole 12 has an upper end surface for axially supporting the bottle mouth. Specifically, the bottle mouth is placed on the second hole 12. The first hole 11 is connected to the second hole 12 to facilitate connection of the bottle mouth to the infusion tube.

[0043] In this application, the device is used to clamp an infusion bottle 100. A gap exists between the first clamping portion 21 and the bottle mouth. Based on the aforementioned dimensional settings, this gap can be controlled to no more than 0.3 mm. The second clamping portion 22 maintains a state of pressing against the sides of the bottle mouth from both sides. Although there is a radial gap between the first and second hole bodies 11, 12 and the bottle mouth, the upper end surface of the second hole body 12 maintains support for the bottle mouth, and the bottle mouth extends from the second hole body 12. The bottle mouth of the infusion bottle 100 is clamped by the first clamping portion 21, the second clamping portion 22, the first hole body 11, and the second hole body 12.

[0044] In this application, the clamp is used to clamp an infusion bag 200. The lower surface of the first clamping portion 21 presses against the upper end of the bottle mouth, while the second clamping portion 22 similarly maintains a tight grip on the sides of the bottle mouth from both sides. The inner surface of the first hole 11 radially secures the bottle mouth, while the upper surface of the second hole 12 supports the bottle mouth. The bottle mouth of the infusion bag 200 is clamped by the first clamping portion 21, the second clamping portion 22, the first hole 11, and the second hole 12.

[0045] The manipulator 41 has an anti-slip groove, the extension direction of the anti-slip groove is parallel to the axial arrangement of the infusion needle tube 4, and a second elastic member 43 is provided in the anti-slip groove, and the second elastic member 43 abuts the anti-slip member 42. Specifically, when the manipulator 41 rises along the groove body 39 formed by the base 3, since the infusion needle tube 4 needs to pierce the bottle mouth of the infusion bottle 100 or the infusion bag 200 upwards, the infusion needle tube 4 will be subjected to an axial downward force. At this time, the anti-slip member 42 and the second elastic member 43 simultaneously shrink and move downward along the anti-slip groove to absorb the axial downward force, and at the same time, the anti-slip member 42 remains fixed to the infusion needle tube 4 by the manipulator 41. A buckle 44 is also provided on the manipulator 41, and the buckle 44 can help further fix the infusion needle tube 4.

[0046] Specifically, a bevel is formed on the outer side of the anti-dropout member 42, and the infusion needle 4 can be easily pushed into the manipulator 41 with the help of the bevel. After being pushed into the manipulator 41, the infusion needle 4 is buckled inside the manipulator 41 and will not detach from the manipulator 41 laterally.

[0047] In addition, the supporting force between the upper surface of the base 3 and the lower surface of the clamping housing 1 can also support the clamping housing 1 to a certain extent, offsetting the influence of the axial force during the puncture process. A support block 19 can also be provided between the base 3 and the clamping housing 1. The support block 19 is provided on the side of the base 3 away from the infusion needle 4 to offset the axial force generated by the infusion needle 4 when puncturing the bottle mouth of the infusion bottle 100 or the infusion bag 200 upward.

[0048] In this embodiment, at least two first sensors 81 for detecting the rotational position of the clamping housing 1 are further provided. The first sensors 81 are arranged in a projection below the rotational path of the clamping hole 10. It is easy to understand that the first sensors 81 can be configured as visual sensors. The two first sensors 81 simultaneously detect the states of the two clamping holes 10 to confirm the rotational position of the clamping housing 1, such as the initial position of the clamping housing 1 or the dressing change position of the clamping housing 1 during the dressing change process.

[0049] In this embodiment, at least one second sensor 71 is provided for detecting the position of the manipulator 41. The second sensor 71 is provided on the side of the manipulator 41 and at the top of the lifting path of the manipulator 41. As will be readily understood, the second sensor 71 can be configured as a proximity sensor or a visual sensor, which is triggered when the manipulator 41 rises to a specified position. Accordingly, during the descent process of the manipulator 41, since it stops when it reaches its lowest position, the descent of the manipulator 41 can be identified by feedback from the current of the drive motor.
