Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a suspension device for a drainage bag. Background Technology
[0002] A drainage bag is a transparent plastic bag used to drain blood and fluid from the body or deep within a surgical site after surgery. Clinically, surgical patients routinely have multiple drainage tubes in place to monitor their prognosis; therefore, patients need to wear drainage bags and urine bags when getting out of bed.
[0003] Traditional suspension devices for drainage bags have some drawbacks. When suspending the drainage bag on the patient's body, the drainage tube needs to be fixed with adhesive tape. Since the drainage tube needs to be firmly fixed to the skin, the tape needs to be pulled tight during operation. This may cause the tape to squeeze the drainage tube, causing the drainage tube to deform, which in turn affects the flow of internal fluid and is not conducive to the suspension and fixation of the drainage tube. Utility Model Content
[0004] The main objective of this invention is to provide a suspension device for drainage bags, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

The suspension auxiliary mechanism includes a protective sleeve placed on the outside of the main drainage tube. A support frame is fixedly connected to the outside of the protective sleeve. A contact frame is fixedly connected to the rear end of the support frame. A placement groove is opened on the outside of the contact frame. A connecting strap is placed inside the placement groove. Adhesive tape is fixedly connected to one end of the connecting strap. A binding strap is fixedly connected to the front end of the connecting strap. A connecting rod is fixedly connected to the upper end of the support frame. A connecting block is fixedly connected to one end of the connecting rod. Adhesive tape is fixedly connected to the rear end of the connecting block.
[0007] Preferably, an upper limit frame is fixedly connected to the outer side of the support frame, the restraint strap is pasted on the lower side of the outer side of the support frame near the upper limit frame, and a lower limit frame is fixedly connected to the lower side of the outer side of the support frame near the restraint strap.
[0008] Preferably, the protective sleeve is arc-shaped, the main body of the protective sleeve is made of rubber, and the contact frame is L-shaped.
[0009] Preferably, the restraint band is U-shaped, the adhesive tape is arc-shaped, and the inner side of the adhesive tape is pasted to the outer side of the drainage tube near the upper side of the protective sleeve.
[0010] Preferably, the lower end of the upper limit frame contacts the upper end of the restraint strap, the upper end of the lower limit frame contacts the lower end of the restraint strap, and the rear end face of the contact frame is flush with the rear end face of the adhesive tape.
[0011] Preferably, the drainage secondary tube is placed inside another set of protective sleeves, the upper end of the drainage main tube is equipped with a main connecting pipe, the upper end of the drainage secondary tube is equipped with a secondary connecting pipe, and the drainage main tube and the drainage secondary tube correspond to each other.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] By placing the support frame on the patient's skin and ensuring the contact frame is in direct contact with the patient's skin, then securing two sets of protective sleeves to the outside of the main drainage tube and the auxiliary drainage tube, attaching the restraint strap to the outside of the support frame, and pulling the adhesive tape to adhere it to the patient's skin, the tensile force of the adhesive tape can be easily transferred from the support frame to the contact frame, and the contact frame can directly transfer the compressive force to the patient's skin.

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] like Figure 1-4 As shown, a suspension device for a drainage bag includes a main drainage tube 1 and a secondary drainage tube 2. A suspension auxiliary mechanism 5 is provided on the outside of the main drainage tube 1. The suspension auxiliary mechanism 5 includes a protective sleeve 51 placed on the outside of the main drainage tube 1. A support frame 52 is fixedly connected to the outside of the protective sleeve 51. A contact frame 53 is fixedly connected to the rear end of the support frame 52. A placement groove 54 is opened on the outside of the contact frame 53. A connecting strap 55 is placed on the inside of the placement groove 54. An adhesive tape 56 is fixedly connected to one end of the connecting strap 55. A restraining strap 57 is fixedly connected to the front end of the connecting strap 55. A connecting rod 58 is fixedly connected to the upper end of the support frame 52. A connecting block 59 is fixedly connected to one end of the connecting rod 58. An adhesive tape 510 is fixedly connected to the rear end of the connecting block 59.
[0021] In this embodiment, an upper limit frame 511 is fixedly connected to the outer side of the support frame 52, and a restraint strap 57 is pasted on the lower side of the support frame 52 near the upper limit frame 511. A lower limit frame 512 is fixedly connected to the lower side of the support frame 52 near the lower side of the restraint strap 57. The protective sleeve 51 is arc-shaped, and the main body of the protective sleeve 51 is made of rubber. The contact frame 53 is L-shaped, the restraint strap 57 is U-shaped, and the adhesive tape 510 is arc-shaped. The inner side of the adhesive tape 510 is pasted to the upper side of the outer side of the drainage main tube 1 near the protective sleeve 51. The lower end of the upper limit frame 511 is in contact with the upper end of the restraint strap 57, the upper end of the lower limit frame 512 is in contact with the lower end of the restraint strap 57, and the rear end face of the contact frame 53 is flush with the rear end face of the adhesive tape 56.
[0022] Specifically, the support frame 52 is positioned corresponding to the main drainage tube 1 and the secondary drainage tube 2, and then placed towards the patient's skin, allowing the contact frame 53 to contact the patient's skin. The two sets of protective sleeves 51 are then secured to the outside of the main drainage tube 1 and the secondary drainage tube 2, and the restraint strap 57 is secured between the upper limit frame 511 and the lower limit frame 512. The restraint strap 57 is then attached to the outside of the support frame 52, and the adhesive tape 56 is pulled to secure the connecting strap 55 inside the placement groove 54. The adhesive tape 56 is then attached to the patient's skin, and the adhesive tape 56, through the restraint strap 57, suspends and fixes the support frame 52 to the patient's skin. With the contact frame 53 supporting the support frame 52, the support frame 52 will not directly compress the main drainage tube 1 and the secondary drainage tube 2, preventing deformation of the main drainage tube 1 and the secondary drainage tube 2. Furthermore, the contact frame 53 can be used to prevent the support frame 52 from being compressed. The force is transmitted to the patient's skin. Then, two sets of adhesive tape 510 are respectively attached to the main drainage tube 1 and the secondary drainage tube 2 to prevent the main drainage tube 1 and the secondary drainage tube 2 from moving. This allows the main drainage tube 1 and the secondary drainage tube 2 to be suspended and fixed to the patient's skin. By placing the support frame 52 on the patient's skin and making the contact frame 53 directly contact the patient's skin, the two sets of protective sleeves 51 are then clipped to the outside of the main drainage tube 1 and the secondary drainage tube 2. The restraint strap 57 is then attached to the outside of the support frame 52, and the adhesive tape 56 is pulled and attached to the patient's skin. This facilitates the transmission of the pulling force of the adhesive tape 56 through the support frame 52 to the contact frame 53, and allows the contact frame 53 to directly transmit the compressive force to the patient's skin, thereby avoiding direct compression of the main drainage tube 1 and the secondary drainage tube 2 and preventing deformation of the main drainage tube 1 and the secondary drainage tube 2.
[0023] In this embodiment, the secondary drainage tube 2 is placed inside another set of protective sleeves 51. The upper end of the main drainage tube 1 is equipped with a main connecting pipe 3, and the upper end of the secondary drainage tube 2 is equipped with a secondary connecting pipe 4. The main drainage tube 1 and the secondary drainage tube 2 correspond to each other.
[0024] Specifically, the main connecting tube 3 and the auxiliary connecting tube 4 are inserted into the patient's body, and the main drainage tube 1 and the auxiliary drainage tube 2 are connected to the drainage bag, so that the fluid in the patient's body flows directly into the drainage bag through the main connecting tube 3 and the auxiliary connecting tube 4.
[0025] Working principle:
[0026] In use, first insert the main connecting tube 3 and the auxiliary connecting tube 4 into the patient's body, and connect the main drainage tube 1 and the auxiliary drainage tube 2 to the drainage bag. Simultaneously, align the support frame 52 with the main drainage tube 1 and the auxiliary drainage tube 2, and place the support frame 52 against the patient's skin so that the contact frame 53 contacts the patient's skin. Then, secure the two sets of protective sleeves 51 to the outside of the main drainage tube 1 and the auxiliary drainage tube 2, and secure the restraint strap 57 between the upper limit frame 511 and the lower limit frame 512. The binding strap 57 is attached to the outside of the support frame 52, and then the adhesive tape 56 is pulled to secure the connecting strap 55 inside the placement groove 54. The adhesive tape 56 is then attached to the patient's skin. The adhesive tape 56, through the binding strap 57, suspends and fixes the support frame 52 to the patient's skin. With the support of the contact frame 53, the support frame 52 does not directly compress the main drainage tube 1 or the secondary drainage tube 2, preventing deformation of the main drainage tube 1 and the secondary drainage tube 2. Furthermore, the contact frame 53 can... The pressure from the support frame 52 is transferred to the patient's skin. Then, two sets of adhesive tape 510 are respectively attached to the main drainage tube 1 and the secondary drainage tube 2 to prevent movement. This allows the main drainage tube 1 and the secondary drainage tube 2 to be suspended and fixed to the patient's skin, enabling the fluid in the patient's body to flow directly into the drainage bag through the main connecting tube 3 and the secondary connecting tube 4. By placing the support frame 52 on the patient's skin and ensuring that the contact frame 53 directly contacts the patient's skin, the two sets of protective sleeves 5... 1. The adhesive tape 56 is attached to the outside of the main drainage tube 1 and the secondary drainage tube 2, and the restraint strap 57 is then attached to the outside of the support frame 52. The adhesive tape 56 is pulled and attached to the patient's skin. This allows the pulling force of the adhesive tape 56 to be transmitted through the support frame 52 to the contact frame 53, and the contact frame 53 to directly transmit the squeezing force to the patient's skin. This avoids direct squeezing of the main drainage tube 1 and the secondary drainage tube 2, and thus avoids deformation of the main drainage tube 1 and the secondary drainage tube 2.
