[0019]
A mattress 14 indicated by a chain line in FIG. 1 is placed on the upper surface of the floor plate body 11, and a user lies on the mattress 14.
[0020]
A plurality of holding members 15 are provided at equal intervals in the longitudinal direction on both sides (only one side is shown) of the bed frame 5. As shown in FIGS. 2 and 3, each holding member 15 has an insertion hole 16 penetrating in the thickness direction. And the side fence 18 is detachably attached to the side part of the bed frame 5 by inserting the lower ends of the pair of legs 17 into the insertion holes 16 of the pair of holding members 15.
[0021]
As shown in FIG. 2, the side fence 18 has a frame-like member 21 whose upper side is formed on a handle portion 19 for a user to hold or put a hand on. The leg portions 17 are provided at the same interval as the holding member 15, and the lower end portion protrudes downward from the lower side of the frame-shaped member 21.
[0022]
As shown in FIG. 3, the outer dimensions of the portion excluding the lower ends of the pair of legs 17 are set larger than the inner diameter of the insertion hole 16 of the holding member 15, and the lower ends of the legs 17 are The outer dimension is formed in the insertion portion 17 a slightly smaller than the inner diameter dimension of the insertion hole 16. The length of the insertion portion 17 a is set so that the lower end slightly protrudes from the insertion hole 16 when the insertion portion 17 a is inserted into the insertion hole 16.
[0023]
A connecting rod 22 as an attachment portion is installed in the middle portion of the pair of leg portions 17 protruding from the frame-like portion 21. The connecting rod 22 is provided with a stopper 23 for preventing the side fence 18 from falling off the holding member 15.
[0024]
As shown in FIGS. 4A to 4C, the retainer 23 is formed by bending a steel bar as an elastic material into a substantially V-shape and engaging portions 24 having substantially U-shaped ends at both ends. The first member 25 formed in the first member 25 and the straight member-like second member 26 having an intermediate portion fixed to a V-shaped bent portion of the first member 25.
[0025]
As shown in FIG. 3, the dimension L ₁ of the engaging portion 24 in a state where the engagement with the connecting rod 22, the connecting rod 22 to the second member 26, the lower end of the insertion portion 17a from the connecting rod 22 up are set to be slightly smaller than the dimension L ₂ of the.
[0026]
In order to hold the side fence 18 so as not to fall out of the holding member 15, that is, the bed frame 5 by the stopper 23, first, the insertion portion 17 a formed at the lower end of the leg portion 17 of the side fence 18 is used as the holding member. It is inserted into 15 insertion holes 16.
[0027]
Next, the engaging portion 24 of the first member 25 of the retainer 23 is rotatably engaged with the connecting rod 22, and the first member 25 is moved from the state indicated by the chain line in FIG. Rotate.
[0028]
Accordingly, the second member 26 enters the lower surface side of the holding member 15 and hits the insertion portion 17a of the leg portion 17 protruding from the lower surface. When the first member 25 is further rotated in the direction of the arrow from this state, the first member 25 undergoes elastic deformation in which the height is increased while the V-shaped width is reduced . The member 26 gets over the lower end surface of the insertion portion 17a protruding from the lower surface of the holding member 15 as shown by a solid line in FIG.
[0029]
Therefore, the retainer 23 is held without disengagement from the holding member 15 by the second member 26 engaging the insertion portion 17a. That is, since the side fence 18 is fixed to the bed frame 5 by the retainer 23, the leg portion 17 of the side fence 18 can be prevented from coming off from the insertion hole 16 of the holding member 15.
[0030]
Thereby, even if a user or another person applies inadvertent external force to the side fence 18, the side fence 18 can be prevented from falling off the bed frame 5.
[0031]
Since the second member 26 of the retainer 23 is linear and the midway portion is fixed to the bent portion of the first member 25, the drainage bag 31 is provided at each end thereof as shown in FIG. Can be hung.
[0032]
In other words, in neurosurgery, cardiac surgery, urology, etc., drainage treatment is performed as a method of placing a guide tube in an incision and continuously inducing and discharging exudate and blood inside the wound. The drainage bag 31 is required for drainage treatment.
[0033]
Conventionally, the drainage bag 31 used for drainage treatment has been fixed to the side surface of the bed frame 5 with adhesive plaster, or provided with a dedicated holder provided on the side surface of the bed frame 5. It was.
[0034]
However, in the former case, the weight of the drainage bag 31 and the adhesive strength of the adhesive bandage may decrease with time, and in the latter case, a dedicated holder is required. There was something that would be up.
[0035]
In the present invention, the second member 26 of the retainer 23 for fixing the side fence 18 to the bed frame 5 is linear, and the middle part of the second member 26 is a V-shaped first member 25. By fixing to the bent portion, the both end portions can be used as holding portions for the drainage bag 31, so that the drainage bag 31 can be securely held and no special parts are required. There is no uplift.
[0036]
Moreover, since the second member 26 is located below the upper surface of the bed frame 5, the drain bag 31 held by the second member 26 is positioned lower than the user who lies on the mattress 14. Therefore, exudate, blood, and the like from the user can be reliably passed through the drainage bag 31.
[0037]
In the above embodiment, the connecting rod 22 is installed on the pair of leg portions 17 of the side fence 18 as an attachment portion for engaging the engaging portion 24 of the retainer 23, but instead of the connecting rod 22, The lower side of the frame-like part 21 of the fence 18 may be used as an attachment part, and the engaging part 24 of the first member 25 may be engaged with the part so as to be rotatable. In that case, if the height dimension of the 1st member 25 is set so that the 2nd member 26 can be engaged with the holding member 15, like the said one Embodiment, the stopper 23 will be favorable. Can be used.
[0038]
Further, the shape of the first member 25 is not limited to the V shape, and may be other shapes such as a U shape. In short, the first member 25 is elastic when the second member 26 is engaged with the holding member 15. Any shape that can be deformed is acceptable.
[0039]
【The invention's effect】
According to the first aspect of the present invention, when the side fence is inserted into the insertion hole of the holding member and the side fence is provided on the bed frame, the first member of the retainer is engaged with the side fence. The second member integrally connected to the first member can be engaged with the holding member.
[0040]
For this reason, the side fence is connected to the holding member by a retaining member, and the leg portion is prevented from coming out of the insertion hole. Therefore, even if inadvertent external force is applied to the side fence, the side fence It can be reliably prevented from coming off the bed frame.
[0041]
In addition, since the retainer elastically deforms the first member and engages it with the holding member, the side fence can be held on the bed frame and the operation of releasing the holding state can be easily performed. .
[0042]
According to the invention of claim 2 , the second member of the stopper is used for holding the drainage bag.
[0043]
Therefore, not only can the drainage bag be securely held, but an exclusive member is not required to hold the drainage bag, which is economical.
[0044]
And since the said 2nd member engages with the lower surface side of a holding member, it is located below the upper surface of a bed frame.
[0045]
Therefore, since the drainage bag held by the second holding member is positioned below the user who lies on the bed frame, it is possible to reliably discharge the exudate and blood from the user.
