Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an inflatable chest armor for protecting the wound after hepatobiliary surgery. Background Art

[0002] After hepatobiliary surgery, in order to observe whether there is bleeding or bile leakage in the early stage of suture of the patient, a drainage tube is usually placed at the wound of the patient for observation, and it can be removed when there is no bleeding or bile leakage in the first two or three days after the operation.

[0003] In order to avoid the damage of the external environment to the surgical wound of the patient after the operation, most of them will protect the wound by wearing a protective chest armor. In the existing protective chest armor, in order to reduce wound bleeding, elastic bands, elastic air bags, etc. are usually used to bandage the wound under pressure. However, in the actual use process, the existence of the drainage tube is not considered. If only a catheter accommodation hole for the drainage tube to pass through is opened on the protective chest armor, on the one hand, only fixing the drainage tube through the catheter accommodation hole will cause the situation of unstable fixation of the drainage tube, which is likely to cause the drainage tube to shift or even break away. On the other hand, when the drainage tube is not needed for drainage, the wound at the catheter accommodation hole of the protective chest armor will not be compressed by the elastic band, elastic air bag, etc. due to the existence of the catheter accommodation hole, thus affecting the wound recovery effect. Summary of the Utility Model

[0004] In order to solve the above problems, the purpose of the utility model is to provide an inflatable chest armor for protecting the wound after hepatobiliary surgery. By setting a conversion mechanism, the switching between two modes of sealing the catheter accommodation hole or clamping the drainage tube can be realized.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An inflatable chest armor for protecting the wound after hepatobiliary surgery, comprising a chest armor body and a conversion component arranged on one side of the front piece of the chest armor body; the conversion component includes a clamping sub-component fixed on the chest armor body, a guiding tube arranged on one side of the clamping sub-component, passing through and embedded in the chest armor wall for allowing the drainage tube to pass through, and a sealing plug arranged on the other side of the clamping sub-component and one end of which is embedded in the chest armor body; a catheter accommodation hole adapted to the guiding tube and a accommodation groove adapted to the sealing plug are correspondingly arranged on the chest armor body, and the inner diameter of the catheter accommodation hole is equal to the inner diameter of the accommodation groove; the chest armor body includes a protective outer armor arranged on the outside, a protective inner armor arranged on the inside, and a pressurizing component arranged between the protective inner armor and the protective outer armor; the catheter accommodation hole sequentially penetrates through the protective outer armor, the pressurizing component and the protective inner armor; the pressurizing component includes an elastic air bag fixed to the inner side surface of the front piece of the chest armor body, a plurality of elastic bands respectively fixed to both sides of the elastic air bag at both ends, and an inflation and deflation interface arranged at the bottom of the elastic air bag for externally connecting an inflation mechanism.

[0007] Preferably, the clamping sub-assembly includes a fixing rod fixed to the breastplate body, connecting rods symmetrically fixed to both ends of the fixing rod, and limiting clips respectively fixed to the ends of the corresponding connecting rods; the two limiting clips are clamped and fixed on the outer surface of the corresponding side of the guide tube or the part of the sealing plug extending out of the breastplate body.

[0008] Preferably, the guide tube is connected to the fixing rod by a first elastic cord, and the sealing plug is connected to the fixing rod by a second elastic cord.

A first connecting buckle is provided inside the shoulder strap of the front piece, and a second connecting buckle adapted to the first connecting buckle is provided at a position corresponding to the first connecting buckle on the outer side of the shoulder strap of the rear piece.

[0010] The utility model has the following beneficial effects:

[0011] With the setting of the conversion component in the utility model, when the drainage tube needs to be used in the early stage after the patient's operation, the guide tube can be placed inside the catheter accommodation hole, and then the drainage tube is passed through the guide tube. The guide tube clamps the drainage tube, thus avoiding the displacement or even detachment of the drainage tube, so as to improve the stability of the drainage tube fixation. When the drainage tube is not needed in the later stage after the patient's operation, the guide tube is taken out from the catheter accommodation hole, and the sealing plug is taken out from the accommodation groove. The sealing plug is placed inside the catheter accommodation hole, and the guide tube is placed inside the accommodation groove, so that the end of the sealing plug abuts against the patient's wound. Through the setting of the sealing plug, it is avoided that some wounds are not pressurized due to the existence of the catheter accommodation hole, thereby improving the wound healing efficiency of the patient.

[0021] The following further describes the present utility model in detail with reference to the accompanying drawings and specific embodiments

[0022] An inflatable wound protection chest armor for hepatobiliary surgery after operation includes a chest armor body 1 and a conversion component 2 provided on one side of the front piece of the chest armor body 1; the conversion component 2 includes a clamping sub-component 21 fixed on the chest armor body 1, a guide tube 22 provided on one side of the clamping sub-component 21 and penetrating and embedded in the chest armor wall of the chest armor body 1 for allowing a drainage tube to pass through, and a sealing plug 23 provided on the other side of the clamping sub-component 21 and having one end embedded in the chest armor body 1; a duct accommodation hole 11 adapted to the guide tube 22 and an accommodation groove 12 adapted to the sealing plug 23 are correspondingly provided on the chest armor body 1, and the inner diameter of the duct accommodation hole 11 is equal to the inner diameter of the accommodation groove 12; the chest armor body 1 includes a protective outer armor 13 provided on the outside, a protective inner armor 14 provided on the inside, and a pressurizing component 15 provided between the protective inner armor 14 and the protective outer armor 13; the duct accommodation hole 11 sequentially penetrates the protective outer armor 13, the pressurizing component 15 and the protective inner armor 14; the pressurizing component 15 includes an elastic airbag 151 fixed to the inner side surface of the front piece of the chest armor body 1, a plurality of elastic bands 152 respectively fixed to both sides of the elastic airbag 151 at both ends, and an inflation and deflation interface 153 provided at the bottom of the elastic airbag 151 for externally connecting an inflation mechanism.

[0023] By changing the settings of the conversion component 2, when the drainage tube needs to be used in the early postoperative period of the patient, the guiding tube 22 can be placed inside the catheter accommodating hole 11. Subsequently, the drainage tube is passed through the guiding tube 22, and the guiding tube 22 clamps the drainage tube, thus avoiding the displacement or even detachment of the drainage tube, so as to improve the stability of the drainage tube fixation. When the drainage tube is not needed in the late postoperative period of the patient, the guiding tube 22 is taken out from the catheter accommodating hole 11, and the sealing plug 23 is taken out from the accommodating groove 12. The sealing plug 23 is placed in the catheter accommodating hole 11, and the guiding tube 22 is placed in the accommodating groove 12, so that the end of the sealing plug 23 abuts against the patient's wound. Through the setting of the sealing plug 23, it is avoided that some wounds are not pressurized due to the existence of the catheter accommodating hole 11, thereby improving the recovery efficiency of the patient's wound; the protective outer armor 13 can protect the part of the patient where the chest armor body 1 is worn, avoiding accidental touching of the patient's wound. The pressurizing component 15 realizes the pressurizing effect on the patient's wound, improving the recovery efficiency of the wound, and the protective inner armor 14 is soft in texture and contacts with the patient's body, which can improve the comfort level of the patient when wearing the chest armor body 1; through the cooperation of the elastic airbag 151 and the elastic band 152, the pressurizing component 15 can be completely attached to the patient's body through the protective inner armor 14, so as to achieve the pressurizing effect on the patient's wound and improve the wound recovery efficiency.

[0024] As a possible implementation manner of this solution, preferably, the clamping sub-component 21 includes a fixing rod 211 fixed on the chest armor body 1, connecting rods 212 symmetrically fixed at both ends of the fixing rod 211, and limit clips 213 respectively fixed at the ends of the corresponding connecting rods 212; the two limit clips 213 are clamped and fixed on the outer surface of the corresponding side of the guiding tube 22 or the part of the sealing plug 23 extending out of the chest armor body 1; through the cooperation of the fixing rod 211, the connecting rods 212 and the limit clips 213, when the guiding tube 22 and the sealing plug 23 are placed at the corresponding positions in the chest armor body 1, the guiding tube 22 and the sealing plug 23 can be clamped to prevent the guiding tube 22 and the sealing plug 23 from detaching from the chest armor body 1 during use.

[0025] As a possible implementation manner of this solution, preferably, the guiding tube 22 is connected to the fixing rod 211 through a first elastic cord 24, and the sealing plug 23 is connected to the fixing rod 211 through a second elastic cord 25; through the setting of the first elastic cord 24 and the second elastic cord 25, it can be avoided that the guiding tube 22 and the sealing plug 23 are lost after being disassembled.

[0026] As a possible implementation of this solution, preferably, the front piece and the rear piece of the protective outer armor 13 are detachably connected. A connecting buckle one 131 is provided on the inner side of the shoulder strap of the front piece, and a connecting buckle two 132 adapted to the connecting buckle one 131 is provided at a position corresponding to the connecting buckle one 131 on the outer side of the shoulder strap of the rear piece; the quick detachment of the protective outer armor 13 can be achieved through the arrangement of the connecting buckle one 131 and the connecting buckle two 132.

[0027] The working principle of this device is as follows:

[0028] In the figure, Z is the skin at the patient's wound. In this device, the outer walls of the guiding tube 22 and the sealing plug 23 have a relatively large coefficient of friction and need to be forced to move. When the patient uses this device, first bandage the patient's wound. When the patient is in the early postoperative stage, install the guiding tube 22 into the catheter accommodating hole 11, first put the protective inner armor 14 on the outside of the patient's body, place the pressurizing assembly 15 and the front piece of the protective outer armor 13 on the front side of the patient's body, pass the drainage tube out through the catheter accommodating hole 11, and then loosen the elastic band 152 around the patient's back. At this time, under the action of the elastic band 152, the pressurizing assembly 15 and the protective outer armor 13 are attached to the front side of the patient's body. Place the rear piece of the protective outer armor 13 on the rear side of the patient's body, and fix the front piece and the rear piece of the protective outer armor 13 through the connecting buckle one 131 and the connecting buckle two 132. Finally, inflate the elastic airbag 151 through an inflating mechanism (such as an inflatable airbag, an air pump, etc.) to achieve pressurization of the patient's wound; when in the late postoperative stage, install the sealing plug 23 into the catheter accommodating hole 11, push the sealing plug 23 inward until the end face abuts against the skin Z at the patient's wound, put on the protective inner armor 14, the pressurizing assembly 15 and the protective outer armor 13 in sequence, and then inflate the elastic airbag 151 through an inflating mechanism (such as an inflatable airbag, an air pump, etc.) to achieve pressurization of the patient's wound.
