Description
本發明係關於一種醫療裝置，尤其是一種使傷口患部處於負壓狀態的負壓醫療裝置。 The present invention relates to a medical device, in particular to a negative pressure medical device that puts the wound in a negative pressure state.
負壓傷口療法((Negative Pressure Wound Therapy,NPWT)為一種輔助療法，係將敷料覆蓋於傷口後，使該敷料與傷口之間的空間形成負壓。根據研究顯示，處於負壓環境下，有助於傷口的癒合。因此，負壓傷口療法常用於例如燒燙傷傷口、手術傷口或者外傷傷口的癒合。 Negative Pressure Wound Therapy (NPWT) is an adjuvant therapy that involves applying a dressing to the wound to create negative pressure between the dressing and the wound. Studies have shown that being in a negative pressure environment helps wounds heal. Therefore, negative pressure wound therapy is often used to heal burns, surgical wounds, or external wounds.
一般來說，施行上述負壓傷口療法時，係將患部覆蓋一層敷料，以使該患部形成一氣密空間，該氣密空間經由一抽氣管連接一動力抽氣泵，醫護人員可以操控該動力抽氣泵調整預定的抽氣壓力以及抽氣時間，使該氣密空間可以形成預定的負壓。由於患部需要長時間維持負壓，因此，在治療期間，患者必須攜帶該動力抽氣泵一同進行移動。然而，該動力抽氣泵體積龐大，須藉助推車或醫療架來協助攜帶，又，該動力抽氣泵亦需要電力來維持運作進而造成患者移動上的限制。再者，該動力抽氣泵的操作仍須仰賴醫護人員進行，造成患者使用上的不便。 Generally speaking, when performing the above-mentioned negative pressure wound therapy, the affected part is covered with a layer of dressing to form an airtight space at the affected part. The airtight space is connected to a powered vacuum pump via a vacuum tube. Medical staff can operate the powered vacuum pump to adjust the predetermined vacuum pressure and vacuum time so that the airtight space can form a predetermined negative pressure. Since the affected part needs to maintain negative pressure for a long time, the patient must carry the powered vacuum pump with him during treatment. However, the powered vacuum pump is large in size and must be carried with the help of a cart or a medical stand. In addition, the powered vacuum pump also requires electricity to maintain operation, which limits the patient's mobility. Furthermore, the operation of the powered vacuum pump still relies on medical staff, causing inconvenience to patients.
為解決上述問題，本發明的目的是提供一種負壓醫療裝置，係 可以方便攜帶，以具有較佳使用便利性者。 In order to solve the above problems, the purpose of the present invention is to provide a negative pressure medical device that can be easily carried and has better convenience of use.
本發明的又一目的是提供一種負壓醫療裝置，操作簡單係可以供患者自行操作者。 Another object of the present invention is to provide a negative pressure medical device that is easy to operate and can be operated by patients themselves.

The three-way valve has a switch, and the switch is used to switch the connection between the air flow channel and the first connection port, the second connection port and the air pressure detection port respectively; and a care piece, which is used to cover the skin around the affected part, so that the care piece and the affected part are in a negative pressure environment. The care piece allows the gas in the negative pressure environment to flow unidirectionally to the suction piece and connect with the suction port of the suction piece. The care piece has an attachment surface, and the care piece has a through hole. The opening at one end of the through hole is located on the attachment surface, and the opening at the other end of the through hole is connected with the second connection port of the three-way valve.
據此，本發明的負壓醫療裝置，藉由該抽吸件中推拉桿的位移對患部周圍之皮膚環境抽氣，使患部周圍之皮膚環境處於負壓環境，即可以不需供電方式對患部周圍之皮膚進行負壓傷口療法，使用者不須隨身攜帶笨重的動力抽氣泵，而可以輕便地移動進行日常生活，可以達到提升患者生活品質的功效。此外，使用者僅需控制該推拉桿於該筒體內位移，即可自行實施負壓傷口療法，不需醫護人員隨身操作，可以達到減少醫事人員人力的消耗的功效。 Accordingly, the negative pressure medical device of the present invention uses the displacement of the push-pull rod in the suction part to evacuate the skin environment around the affected part, so that the skin environment around the affected part is in a negative pressure environment, that is, negative pressure wound therapy can be performed on the skin around the affected part without power supply. The user does not need to carry a bulky power vacuum pump with him/her, but can move it easily to carry out daily life, which can achieve the effect of improving the patient's quality of life. In addition, the user only needs to control the displacement of the push-pull rod in the cylinder to implement negative pressure wound therapy by himself/herself, without the need for medical staff to operate it, which can achieve the effect of reducing the manpower consumption of medical staff.
其中，該筒體的一端成縮口狀以形成該吸氣口。如此，該吸氣口可以便於結合該三向閥之功效。 Among them, one end of the cylinder is contracted to form the air intake port. In this way, the air intake port can be conveniently combined with the function of the three-way valve.
其中，該容室鄰近於該吸氣口藉由該筒體的縮徑而形成一檔止部。如此，該檔止部可以用以供該推拉桿的一端抵靠之功效。 The chamber is adjacent to the air inlet and forms a stop portion by reducing the diameter of the cylinder. Thus, the stop portion can be used to provide a support for one end of the push-pull rod.
其中，該氣密件為一塞體，該氣密件位於該推拉桿的一端，使該氣密件朝向該吸氣口。如此，該推拉桿帶動該氣密件可以由該吸氣口形成吸氣的功效。 The airtight member is a plug body, and the airtight member is located at one end of the push-pull rod, so that the airtight member faces the air inlet. In this way, the push-pull rod drives the airtight member to form an air inlet effect.
其中，該氣密件為一O環，該氣密件套設於該推拉桿的環周面，以使該氣密件以徑向緊貼於該筒體的內周壁。如此，該推拉桿帶動該氣密件可以由該吸氣口形成吸氣的功效。 The airtight part is an O-ring, which is sleeved on the circumferential surface of the push-pull rod so that the airtight part is radially tightly attached to the inner circumferential wall of the cylinder. In this way, the push-pull rod drives the airtight part to form the effect of suction through the suction port.
其中，該氣流道為一T字流道，使該第一連接口與該第二連接口分別位於一X方向上的相對兩端，以及使該氣壓偵測口位於一Y方向上的一端。如此，該切換件可以位於該氣流道中該X方向與該Y方向的交會處，使該切換件可以依轉動方向依序遮擋該氣流道與該第一連接口、該第二連接 口及該氣壓偵測口的連通之功效。 The air flow channel is a T-shaped channel, so that the first connection port and the second connection port are located at two opposite ends in an X direction, and the air pressure detection port is located at one end in a Y direction. In this way, the switch can be located at the intersection of the X direction and the Y direction in the air flow channel, so that the switch can sequentially block the connection between the air flow channel and the first connection port, the second connection port and the air pressure detection port according to the rotation direction.
其中，該照顧件的貫通孔藉由一連接軟管連通於該三向閥的第二連接口。如此，可以藉由該連接軟管使該抽吸件具有較大的活動範圍，以方便使用者進行操作，具有提升操作便利性的功效。 The through hole of the care piece is connected to the second connection port of the three-way valve through a connecting hose. In this way, the suction piece can have a larger range of motion through the connecting hose to facilitate the user's operation, which has the effect of improving the convenience of operation.
其中，該三向閥的第一連接口可拆裝地連接於該抽吸件的吸氣口。如此，使用者在維持患部周圍之皮膚的負壓後，即可將該抽吸件移除，可以輕便地移動進行日常生活，係具有提升生活品質的功效。 The first connection port of the three-way valve is detachably connected to the suction port of the suction device. In this way, the user can remove the suction device after maintaining the negative pressure on the skin around the affected area, and can easily move it to carry out daily life, which has the effect of improving the quality of life.

綜上所述，本發明的負壓醫療裝置，藉由該抽吸件中推拉桿的位移對患部周圍之皮膚環境抽氣，使患部周圍之皮膚環境處於負壓環境，即可以不需供電方式對患部周圍之皮膚進行負壓傷口療法，使用者不須隨身攜帶笨重的動力抽氣泵，而可以輕便地移動進行日常生活，可以達到提升患者生活品質的功效。此外，使用者僅需控制該推拉桿於該筒體內位移，即可自行實施負壓傷口療法，不需醫護人員隨身操作，可以達到減少醫事人員人力的消耗的功效。 In summary, the negative pressure medical device of the present invention uses the displacement of the push-pull rod in the suction part to evacuate the skin environment around the affected part, so that the skin environment around the affected part is in a negative pressure environment, that is, negative pressure wound therapy can be performed on the skin around the affected part without power supply. The user does not need to carry a bulky power vacuum pump with him/her, but can move it easily in daily life, which can improve the patient's quality of life. In addition, the user only needs to control the displacement of the push-pull rod in the cylinder to implement negative pressure wound therapy by himself/herself, without the need for medical staff to operate it, which can reduce the manpower consumption of medical staff.
