Description

Technical Field

[0001] The utility model belongs to the technical field of negative pressure drainage devices, and particularly relates to a VSD negative pressure drainage device. Background Technique

[0002] The VSD negative pressure closed drainage technology is a technology that uses VSD materials + semi-permeable membranes + three-way connecting pipes + negative pressure aspirators for negative pressure suction. The main technical indications mainly include trauma: large-area avulsion injuries, degloving injuries, and large-area defects of fur tissues; burns: this therapy can be used for those that cannot be skinned in the first stage; osteomyelitis: in combination with minimally invasive drilling, it can reach the lesion directly and has a very good treatment effect; others: pressure sores, non-healing wounds, and diabetic feet. The VSD negative pressure drainage technique is a brand-new method for treating superficial wounds and for deep drainage. It can completely remove the secretions and necrotic tissues in the cavity or wound, and has a very good treatment effect on diseases such as osteomyelitis that are difficult to treat internally. It is an innovation in surgical treatment techniques.

[0003] The patent with the publication number CN219049707U discloses a simple VSD negative pressure suction device. The sterile gauze includes an upper sterile gauze layer and a lower sterile gauze layer. One ends of the drainage tube and the moistening liquid tube are located between the upper sterile gauze layer and the lower sterile gauze layer. First side holes and second side holes are respectively provided at the inner ends of the drainage tube and the moistening liquid tube. Then, when the negative pressure device at the outer end of the drainage tube is started, the tissue fluid at the wound surface can be aspirated and discharged through the drainage tube.

[0004] However, when the patient is transferred from the operating room to the ward or goes out for examination with VSD, the wall-mounted negative pressure (negative pressure device) needs to be disconnected, which will cause the wound to have no negative pressure and expand, failing to achieve the treatment purpose, and increasing the risk of reflux and infection. Content of the Utility Model

[0005] The purpose of the utility model is to provide a VSD negative pressure drainage device, which can reduce the possibility of the patient being infected.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A VSD negative pressure drainage device, comprising:

[0007] A VSD dressing, with a drainage tube connected to the VSD dressing;

[0008] A negative pressure ball, with a first connecting tube and a second connecting tube respectively arranged at both ends of the negative pressure ball. The first connecting tube is communicated with the drainage tube, and the second connecting tube is communicated with a negative pressure device;

[0009] A closing plate, with a rectangular groove and a long strip-shaped groove arranged inside the closing plate. The rectangular groove and the long strip-shaped groove are connected through a transition inclined surface, and the second connecting tube passes through the rectangular groove.

[0010] Further, it further includes a lid, which is detachably connected to the second connecting pipe.

[0011] Further, a convex ring is provided at the end of the second connecting pipe, a connecting ring is sleeved on the second connecting pipe, the connecting ring is arranged between the negative pressure ball and the convex ring, and a connecting piece is fixed between the convex ring and the lid.

[0012] Further, the joints of the transition inclined surface with the rectangular groove and the long strip groove are both transitioned by arcs.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] (1) When the patient needs to disconnect the negative pressure device during an external examination, first separate the negative pressure device from the second connecting pipe, then flatten the negative pressure ball, and then squeeze the second connecting pipe located in the rectangular groove into the long strip groove. Since the second connecting pipe is a flexible pipe, it can be squeezed into the long strip groove, thereby closing the second connecting pipe to form a closed environment and avoid being infected;

[0015] (2) The lid is inserted into the second connecting pipe, which can prevent contamination;

[0016] (3) The connecting ring and the connecting piece can connect the lid to the second connecting pipe, prevent the lid from being lost, and make the use more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 - 3 , the present utility model provides a technical solution for a VSD negative pressure drainage device.

[0023] A VSD negative pressure drainage device, comprising:

[0024] A VSD dressing 1, with a drainage tube 2 connected thereto;

[0025] A negative pressure ball 3, with a first connecting tube 4 and a second connecting tube 5 respectively arranged at both ends thereof. The first connecting tube 4 is communicated with the drainage tube 2, and the second connecting tube 5 is communicated with a negative pressure device 6;

[0026] A closing plate 7, with a rectangular groove 8 and a long strip-shaped groove 9 arranged therein. The rectangular groove 8 and the long strip-shaped groove are connected through a transition inclined surface 10, and the second connecting tube 5 passes through the rectangular groove 8.

[0027] During normal use, the second connecting tube 5 is located in the rectangular groove 8, and it can be judged whether the negative pressure fails by whether the negative pressure ball 3 expands. When the patient goes out for an examination and needs to disconnect the negative pressure device 6 (wall-mounted negative pressure), first separate the negative pressure device 6 from the second connecting tube 5, then flatten the negative pressure ball 3, and then squeeze the second connecting tube 5 located in the rectangular groove 8 into the long strip-shaped groove 9. Since the second connecting tube 5 is a flexible tube, it can be squeezed in the long strip-shaped groove 9, thereby closing the second connecting tube 5 and forming a closed environment to avoid infection. Since the negative pressure ball 3 is flattened at this time, it can be observed whether the negative pressure ball 3 leaks air. If there is air leakage, the negative pressure ball 3 will expand.

[0028] As Figure 2 shown, the drainage device further comprises a lid 11, and the lid 11 is detachably connected to the second connecting tube 5.

[0029] When going out for an examination is required, the closing plate 7 closes the second connecting tube 5, and then the lid 11 is inserted into the second connecting tube 5, which can prevent contamination.

[0030] As Figure 2 shown, the end of the second connecting tube 5 is provided with a convex ring 12, a connecting ring 13 is sleeved on the second connecting tube 5, the connecting ring 13 is arranged between the negative pressure ball 3 and the convex ring 12, and an elastic plastic connecting member 14 is fixed between the convex ring 12 and the lid 11. The connecting ring 13 and the connecting member 14 can connect the lid 11 to the second connecting tube 5, avoiding the loss of the lid 11 and making the use more convenient.

[0031] As Figure 3 shown, the joints of the transition inclined surface 10 with the rectangular groove 8 and the long strip-shaped groove 9 are both transitioned through an arc 15, which can prevent the second connecting tube 5 from being scratched during the process of being squeezed from the rectangular groove 8 into the long strip-shaped groove 9.

[0032] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
