Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a fixing device for an infusion pump. Background Art

[0002] An infusion pump is a mechanical or electronic infusion control device that controls the infusion speed by acting on the infusion catheter. It is often used in situations where the infusion speed and amount of medicine need to be strictly controlled, such as when using pressor drugs, antiarrhythmic drugs, and intravenous infusion or intravenous anesthesia for infants and young children. When using an infusion pump to infuse a patient, the fixed position of the infusion pump must be considered. When fixing the infusion pump on the infusion stand, use the fixing clip behind the infusion pump to fix the infusion pump at an appropriate height of the ordinary infusion stand and tighten the knob. The fixing parts of the prior art include a ring mounted on the infusion stand and a bolt inserted in the ring. The ring is fixed to the vertical tube body of the infusion stand by tightening the bolt. However, in the traditional structure, once the contact point between the bolt and the infusion stand is not firm, the infusion pump will loosen and fall. Utility Model Content

[0004] As an improvement, it also includes an anti-slip sleeve, which is mounted on the vertical rod of the infusion support. The anti-slip sleeve has a conical outer side surface, and the outer diameter of the top end of the anti-slip sleeve is smaller than the outer diameter of the bottom end.

[0005] As a further improvement, it also includes a conical sleeve, which is sleeved on the vertical rod of the infusion bracket. The conical sleeve consists of an outer sleeve and two elastic clips arranged in the outer sleeve. The outer sleeve is sleeved on the outside of the conical column and is movably connected with the two elastic clips. Each elastic clip is provided with a groove on the inner wall. The top ends of the two elastic clips are fixedly connected by fasteners and clamped on the infusion bracket.

[0013] The following embodiments further illustrate the content of the present utility model, but should not be construed as a limitation to the present utility model. In the following embodiments, the present utility model detachably hangs the infusion pump on the infusion stand, and the infusion stand is a cylindrical tube.

[0014] Embodiment 1

[0015] The structure of this embodiment is as shown in Figure 1-2 , this embodiment includes a clamping member 2 for detachably fixing the infusion pump 0 on the vertical rod 1 of the infusion stand. The clamping member 2 includes a hoop body 20 provided with an opening. At the end of the opening of the hoop body 20, there is a clamping portion 21, and the clamping portion wraps an elastic coating layer 22. On the side of the hoop body 20 away from its opening, there is a protruding portion 23, and the protruding portion 23 is fixedly connected to the housing of the infusion pump 0. It can be quickly disassembled and installed, and can also increase the contact area with the vertical rod of the infusion stand and enhance the anti-slip effect.

[0016] Figure 1 The clamping member 2 shown in the illustrated Embodiment 1 is a U-shaped clamping member, and the clamping portion 21 at its open end is columnar. The specific shapes of the clamping members in some other embodiments can be appropriately adjusted on the basis of Figure 1 , for example, the clamping portion can be specifically set as spherical or hemispherical.

[0017] In some other embodiments, a spherical movable joint is provided at the fixed connection between the protruding portion 23 and the housing of the infusion pump 0 ( Figure 1 not shown). A joint ball is provided at the end of the protruding portion, and the joint ball can be movably arranged in the joint ball cavity, and the joint ball cavity is fixed to the housing of the infusion pump. This enables the protruding portion to move within a certain range and allows for fine adjustment of the hanging angle of the infusion pump.

[0018] Embodiment 2

[0019] On the basis of Embodiment 1, this embodiment further includes Figure 1The anti-slip sleeve 3 shown, the anti-slip sleeve 3 is sleeved on the vertical rod 13 of the infusion stand, the anti-slip sleeve 3 has an outer side surface with a conical shape, and the outer diameter of the top end of the anti-slip sleeve is smaller than the outer diameter of its bottom end.

[0020] Figure 3 One end with a larger outer diameter of the outer sleeve tube of the shown embodiment is provided with a protrusion extending away from the infusion stand.

[0021] The anti-slip sleeve is used in cooperation with the clamping member 2 as Figure 1-2 shown. When the inclined surface of the conical shape of the anti-slip sleeve abuts against the lower edge of the clamping member 2, this inclined surface divides the load-bearing of the infusion pump to generate a pressure in the axial direction of the vertical rod, so the friction force with the vertical rod is greater and the infusion pump is not likely to fall.

[0022] Embodiment 3

[0023] On the basis of Embodiment 1, this embodiment further includes Figure 3 the conical sleeve 4 shown. The conical sleeve is sleeved on the vertical rod 1 of the infusion stand. The conical sleeve 4 is composed of an outer sleeve tube 41 and two elastic clip pieces 42A, 42B arranged inside the outer sleeve tube. The outer sleeve tube 41 is sleeved on the outside of the conical column and is movably connected to the two elastic clip pieces 42A, 42B. Each elastic clip piece is provided with a groove 43 on the inner wall. The top ends of the two elastic clip pieces are fastened to the infusion stand through a fastener 44. After the two elastic clip pieces are closed, they form a conical column with a thinner upper end and a thicker lower end, and the outer sleeve tube 41 is sleeved on the conical column. The outer sleeve tube 41 is provided with an opening for installation ( Figure 3 not shown).

[0024] During use, the two elastic clip pieces are fastened to the vertical rod of the infusion stand through a fastener. The outer sleeve tube is sleeved on the outside of the two elastic clip pieces, and the smaller-diameter end of the outer sleeve tube faces upward. The infusion stand passes through the groove in the middle of the two elastic clip pieces.

[0025] When the first fixing member sags downward to contact the outer sleeve tube after bearing the load, the outer sleeve tube converts the vertically downward gravity into a component in the direction of the axis of the infusion stand and applies it to the two elastic clip pieces in the middle, causing them to contact and clamp on the surface of the infusion stand, thereby making the infusion pump not easy to fall.

[0026] In some cases, even if the infusion pump moves vertically due to the instability of the first fixing member, it will not fall immediately but has a downward buffer in the vertical direction.

[0027] In the above embodiments, the fastener is any one of a clamp and a hoop.
