Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of negative pressure drainage bags, in particular to a negative pressure drainage bag which is easy to read. Background Art
[0002] The disposable negative pressure drainage bag consists of a cover and a bag body, and is used in conjunction with a negative pressure drainage device to collect waste fluid outside the body (where the negative pressure drainage device consists of a negative pressure drainage bag, an outer bottle, a connecting tube and a metal frame). When using the negative pressure drainage bag, first unpack the negative pressure drainage bag, then put the bag body of the negative pressure drainage bag into the outer bottle, fix the cover in the outer bottle, and finally connect the interface of the drainage bag to the connecting tube.
[0003] As in the prior art, the patent with the patent authorization announcement number CN216417910U discloses a disposable negative pressure collection bag for medical drainage fluid, including a bag body, a scale bar connected to the front end of the outer wall of the bag body; a cover plate connected to the top of the bag body, and an elastic sealing pad connected to the outer wall of the cover plate; a sealing cover connected to the top of the functional hole; and a docking port arranged on one side of the functional hole. The disposable negative pressure collection bag for medical drainage fluid can extract the inside of the device through the functional hole, and can also place liquid medicine, which is very convenient. The sealing cover is closed, and the docking port can be used to dock the device with the diversion mechanism, so as to facilitate the entry of liquid into the bag; the elastic sealing pad can effectively improve the connection effect between the bag body and the cover plate, improve the connectivity, and the adhesive patch can further improve the connectivity between the bag body and the cover plate; the scale bar can accurately judge and observe how much liquid is in the bag body, so as to facilitate the use of the device.
[0004] Although the drainage bag in the above patent can accurately judge and observe the amount of liquid in the bag through the scale bar, thereby facilitating the use of the device, the drainage bag is generally folded and compressed when leaving the factory in order to reduce the space occupied. This causes the drainage bag to be in a wrinkled state. When the drainage bag is placed in the outer bottle and the amount of drainage fluid entering the drainage bag is small, the drainage bag will still be in a wrinkled state, which makes it difficult for medical staff to read the drainage fluid more accurately, which is not conducive to medical staff's observation and judgment of the condition.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] See also Figure 1-7 A negative pressure drainage bag that is easy to read includes a cover body 1, a bag body 2 is fixedly connected to the bottom of the cover body 1, a support ring 3 is provided around the bottom of the bag body 2, the inner wall of the support ring 3 is fixedly connected to the outer wall of the bag body 2, and a connecting ring 4 is rotatably connected to the outer side of the support ring 3, and the connecting ring 4 is movably connected to the cover body 1.
[0024] The easy-to-read negative pressure drainage bag in the utility model is configured to expand the bottom of the bag body 2 by the expansion ring 3, and then expand the side wall of the bag body 2 by the weight of the expansion ring 3 and the connecting ring 4, so that the entire bag body 2 is in an expanded state, and the surface of the bag body 2 is relatively flat, so that the drainage fluid will be directly at the bottom of the bag body 2 after entering the bag body 2, which is convenient for reading through the scale on the drainage bag. Since the bag body 2 is relatively flat, the read numbers will also be more accurate. In addition, the structure of the cover body 1 and the bag body 2 in the utility model is similar to the structure of the disposable negative pressure collection bag for medical drainage fluid disclosed in the patent authorization announcement number CN216417910U, so no further elaboration will be made here.
[0025] like Figure 3 , Figure 6 and Figure 7 As shown, a limiting groove 10 is formed on the outer wall of the expansion ring 3 , and a limiting ring 11 is fixedly connected to the inner wall of the connecting ring 4 , and the limiting ring 11 matches the limiting groove 10 .
[0026] like Figure 4 , Figure 5 and Figure 7 As shown, the outer wall of the lower end of the cover body 1 is provided with a plurality of hooking grooves 8, which are evenly distributed. A plurality of hooking blocks 9 are fixed to the top of the connecting ring 4, and the positions of the hooking blocks 9 match those of the hooking grooves 8.
[0027] Specifically, after the drainage bag is produced, it is necessary to fold the drainage bag to reduce the space occupied. At this time, it is only necessary to move the connecting ring 4 toward the direction of the cover body 1 so that the bag body 2 is folded between the cover body 1 and the connecting ring 4, and at the same time rotate the connecting ring 4 to align the hook block 9 with the hook groove 8, and then insert the hook block 9 into the hook groove 8, and rotate the connecting ring 4 again so that the hook block 9 is hooked in the hook groove 8.
[0028] like Figure 5 and Figure 6 As shown, a plurality of slots 6 are provided on the top of the support ring 3 , and the slots 6 are evenly distributed. A plurality of blocks 7 are fixedly connected to the bottom of the cover body 1 , and the positions of the blocks 7 match those of the slots 6 .
[0029] Specifically, before the hook block 9 is inserted into the hook groove 8 , the clamping block 7 can be inserted into the clamping groove 6 , so as to fix the expansion ring 3 and prevent the expansion ring 3 from rotating with the connecting ring 4 , causing the bag body 2 to be twisted.
[0030] like Figure 5 and Figure 6 As shown, the inner wall of the slot 6 is fixed with an iron sheet 601, and the outer wall of the block 7 is fixed with a magnetic sheet 701. The magnetic sheet 701 on the opening ring 3 will attract the iron sheet 601 on the cover 1, thereby playing a pre-fixing role to prevent the opening ring 3 from separating from the cover 1 by itself.
[0031] like Figure 3 and Figure 7 As shown, a counterweight 5 is fixedly connected to the inner wall of the lower end of the connecting ring 4, and the top of the counterweight 5 fits the bottom of the bag body 2. The counterweight 5 increases the weight of the connecting ring 4 and the opening ring 3, so that the side wall of the bag body 2 is more easily straightened and kept flat, and it is easier to rotate the connecting ring 4 through the counterweight 5.
[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
