Aseptic tent

Technical field

[0001] The present invention relates to a sterile tent. A sterile tent is a sealed tent-like structure for aseptic operation that is configured so that a substantially sealed space is formed between the patient and the practitioner, and surgery can be performed aseptically within the sealed space. It is.

Background art

Conventionally, surgical operations in an operating room and catheter diagnosis and treatment in an angiography room are performed in an environment that takes into account the prevention of bacterial infection in patients.

[0003] However, the risk of infection of the surgeon by blood that bleeds from the site of insertion into the operative field or blood vessel is sufficiently considered. Always performs procedures in an environment exposed to the risk of blood infection. Traditionally, the ability to avoid danger to some extent by using surgical gowns and masks. These are originally intended primarily to protect the patient side, and the surgeon's risk of infection is sufficient. What can be avoided in the future?

[0004] Accordingly, there has been a strong desire to provide a device that can easily and completely avoid the risk of blood infection of an operator without impairing the degree of freedom of the operator's procedure. Treatment with surgery also has the problem of bedside contamination with blood.

Disclosure of the invention

Problems to be solved by the invention

[0005] The present invention has been made in view of the above circumstances, and is capable of preventing bedside contamination by blood and infection of a surgeon and substantially performing surgery aseptically. It is an object to provide a sterile tent configured to maintain a sealed space.

Means for solving the problem

[0006] The sterile tent of the present invention includes a support member that forms a skeleton of a sealed tent-like structure, a transparent and flexible sheet-like tent body that forms an outer shell or a wall of the closed tent-like structure, A flexible sheet-like bottom wall that closes the bottom, and both longitudinal ends of the tent body are closed A flexible sheet-like side wall, and the support member is provided integrally with the tent main body, and the bottom wall is provided with an opening for exposing a treatment site of a patient in the vicinity of a peripheral edge thereof. The body is provided with a pair of hand insertion portions for aseptically inserting the operator's hand into the tent in proximity to the treatment site exposure opening, while the treatment site is provided on the tent body or the side wall. Opening force for exposure It is characterized in that a closed medical device entrance that can be opened and closed for carrying medical devices necessary for the treatment is provided at a position apart from the opening force.

[0007] The sheet forming the tent body is preferably a film or a flexible thin sheet formed of a transparent plastic such as polyethylene, polyester, soft polysilvule, polyamide. In addition, the sheet forming the bottom wall and the side wall may be a flexible film or sheet formed of a plastic such as polyethylene, polyester, soft polysilvose, polyamide or the like, and is not necessarily transparent. There is no need. Therefore, the sheet forming the bottom wall and the side wall may be opaque in order to shield the region other than the treatment site. The materials of the tent body sheet, the bottom wall sheet, and the side wall sheet may be the same or different from each other.

[0008] As the support member, any member can be used as long as it has an inflatable membrane structure and can form an air column. Preferably, the support member expands by injecting a gas to form a sealed tent-like structure. A flexible tubular member that forms the bone is used. In addition, the support member is usually formed integrally from a plurality of support elements. In this case, adjacent support elements are directly connected to each other, but some or all of them are connected via connectors. It is okay to be connected. The strut element may be formed separately from the sheet constituting the tent body, or may be formed integrally with the sheet constituting the tent body. In the case where the column element is formed separately from the sheet constituting the tent body, for example, two long sheets are bonded to each other in the longitudinal direction. In the case where the column element is formed integrally with the sheet constituting the tent body, for example, the relatively wide V, the width of the wide sheet in the width direction of one end of the sheet, the length of the wide sheet, etc. A relatively narrow sheet is arranged, and the wide sheet and the narrow sheet are bonded to each other on two sides in the longitudinal direction of the narrow sheet. In addition, the four sides of the tent main body rectangular sheet are folded and the edges are overlapped, and the strip sheet is disposed on the strip sheet so as to cross over the edges. After welding the overlapping part of the rectangular sheet for the tent main body and the tent body, welding is performed along both edges of the strip sheet and the overlapping part of the rectangular sheet for the tent main body to form a column member. Also good. It is preferable that the gas inlet to the support member is provided in a portion adjacent to the bottom wall of the support member.

[0009] Further, a sealing means that is in close contact with the periphery of the treatment site is provided at the peripheral edge of the treatment site exposure opening to prevent the treatment site exposure opening from being displaced from the operation site, and in the outside tent. In this case, the sealing means is preferably an adhesive tape. The hand insertion part is formed in a glove box composed of an arm attachment part and a glove-like hand attachment part, and at least the hand attachment part itself has excellent lubricity. The tip of the finger attachment part is formed to a length that can be easily broken by wearing the finger and that the finger is sufficiently exposed after the break.

[0010] Thus, a better understanding of the power generally describing the present invention can be obtained by reference to certain specific embodiments. These examples are provided herein for illustrative purposes only and are not limiting unless otherwise specified.

The invention's effect

[0011] According to the present invention, the following effects can be expected. That is, this aseptic tent has a flat shape that is folded when not in use, and injects air or other gas into the support member and expands the support member to form a skeleton when in use. Thus, a substantially sealed space is formed between the patient and the practitioner, and aseptic surgery or the like can be performed in the sealed space.

[0012] Therefore, since operations such as surgery and diagnosis' treatment can be performed in a substantially sealed space isolated from the operator, bedside contamination and risk of blood infection of the operator are prevented. I can do it. In addition, the risk of infection in the patient can be further reduced by maintaining a clean environment at the surgical site and the site where the blood vessel is inserted. It is economical because it eliminates the need for gowns, masks, and coverings. Further, it is mainly composed of a column member and a wall sheet, so it is lightweight and easy to fold, and easy to dispose after use. Brief Description of Drawings

As shown in FIG. 1 and FIG. 2, the aseptic tent of Example 1 is a flexible tubular strut member 1 that is expanded by gas injection to form a skeleton of a sealed tent-like structure, and a sealed tent. The transparent and flexible sheet-like tent body 20 that forms the wall of the structure, the flexible sheet-like bottom wall 25 that closes the bottom, and the flexible sheet that closes both ends in the longitudinal direction of the sealed tent-like structure The support member 1 is formed integrally with the tent body 20. These members are made of a transparent and flexible plastic such as polyethylene.

[0019] The tent body 20 is a rectangular shim that forms the front and back walls of a sealed tent-like structure. The side wall 21, 22, 23, 24 is formed by the support member 1 and parallel to the longitudinal direction of the sealed tent-like structure. The bottom wall 25 is formed of a rectangular sheet having the same length as that of the ten-rod body sheet 2 and a narrower width, and the long side portions thereof are respectively welded to the long side parts of the tent body sheet 2. The short sides are welded to the bottoms of the side walls 26 and 27, respectively. The side wall 26 has a side edge and an arch portion welded to the short side edge of the tent main body sheet 2. The side wall 27 is a lower side portion of the side edge and has a short side portion of the tent main body sheet 2. The remaining ridges and arches are fixed to the tent body sheet 2 with an adhesive tape or a hook-and-loop fastener (for example, Velcro (registered trademark)).

The bottom wall 25 is provided with a treatment site exposure opening 3 adjacent to the side wall 26, and a pair of side walls 21 adjacent to the side wall 26 is adjacent to the treatment site exposure opening 3. The hand insertion part 4 is provided, and the side wall 27 opposite to the longitudinal side wall 26 is provided with a closed medical device entrance 5 for opening and closing the medical device necessary for the operation. .

[0021] The strut member 1 is a flexible member constituting the skeleton of the sealed tent-like structure, has an inflatable membrane structure, and expands into a tube shape by injecting a gas such as compressed air to form an air column. The tent is maintained in a tensioned state and consists of a plurality of flexible strut elements (for example, in FIG. 1 and FIG. 2, strut elements 111, 112, 121, 122, 131, 132, 141, 142, 151, 152, 161, 162).

[0022] The strut member 1 includes, for example, a tent main body sheet 2 and a plurality of two types of long sheets 201, each having the same length and width as the tent main body sheet 2, as shown in FIG. 212 is formed integrally with the tent body 20. Specifically, for example, as shown in FIG. 4, the support member 1 is first formed on a support element forming portion including four sides of a rectangular tent body sheet 2, that is, on the tent body sheet 2. The long sheets 202 are arranged in parallel in the longitudinal direction at a predetermined interval in the width direction, and the long sheets 201 are arranged in parallel in the width direction at predetermined intervals in the longitudinal direction. , 212 overlapping parts are welded. Next, a tubular member that forms an openable / closable gas inlet 6 for expanding the column member 1 is disposed at an appropriate position of the tent main body sheet 2, for example, a portion adjacent to the bottom wall 25. As shown in Fig. 5, the tent body sheet 2 and the long sheets 201 and 212 are welded at the hatched portions 101, and the outer wall of the column element is attached along the four sides of the tent body sheet 2. Form. Next, as shown in FIG. 6, if the hatched portions 102, 103, 104, 105 are welded along the long sheets 201, 212 at a predetermined interval inside the welded portion 101, the column member 1 is formed. I can do it. The welding portion 101 can be used as a welding margin for welding the bottom wall 25 and the wall sheets 26 and 27 at both ends in the longitudinal direction.

[0023] Further, the side wall 27 is welded to the adjacent bottom wall 25 portion and the support element 151, 152 portion of the welding margin 101 adjacent to the bottom wall adjacent portion, and the other portion is welded allowance of the column element 151, 152 portion. It is detachably fixed to 101 by a sealing means (not shown) such as a button or a hook-and-loop fastener, and can be used as an entrance 5 for medical equipment such as a tray guide wire. The medical device delivery port 5 is used to carry in only the tray, and a medical device delivery port may be provided separately on the side wall 24 if necessary.

[0024] Since the tent is placed on the patient's body, the shape on the welding side of the side walls 26, 27 and the bottom wall 25 is formed in a circular arc shape so as to be easily deformed along the patient's body shape. May be. In addition, by attaching a hook-and-loop fastener to the bottom wall 25 so that the bottom wall 25 can be fixed to a surgical support table, etc., and the fixing width is slightly narrower than the width of the bottom wall, the bottom wall 25 is slightly You can make it fool!

[0025] The shape of the roof of the tent may be, for example, a flat roof shape having a top wall or a dome shape. However, as shown in Fig. 1, the side walls 21, 22, 23, and 24 are inclined. It is also possible to form a shape that intersects and forms a ridge at the intersection.

[0026] Adhesive tape 31 that is in close contact with the periphery of the treatment site is attached to the peripheral edge of the treatment site exposure opening 3 to prevent the surgical site force of the treatment site exposure opening 3 from being shifted and the outside air. Inflow into the tent is prevented.

[0027] The hand insertion portion 4 is a so-called glove box including an arm attachment portion 41 and a glove-like hand attachment portion 42, and at least the hand attachment portion 42 is usually made of polyethylene, polyamide, polytetraflur. It is made of plastic that itself has excellent lubricity, such as polyethylene. The tip of the finger attachment portion 43 of the hand attachment portion 42 is formed to a length that can be easily broken by attaching the finger and that the finger is sufficiently exposed after the break. Lubricity may be improved by applying silicone oil to the outer wall of the hand-mounted portion 42. Although not shown, the side wall 21 has an assistant's hand on the support element 141 side from the hand insertion portion 4. A similar assistant hand inserting portion for inserting the above may be provided. The bottom wall 25 may be provided with a drain hole (shown! / ヽ) near the side wall 27 !.

[0028] In this structure, the column member 1 is formed integrally with the side wall parallel to the longitudinal direction, and the bottom wall 25 and the side walls 26 and 27 at both ends in the longitudinal direction are attached to the column member 1 so that manufacturing is easy. Is. In addition, if the material for forming the hand mounting portion 4 is made of the same material as the material for forming the side wall, it can be easily fixed to the side wall 21 by a method such as welding, so that the hand mounting portion 4 can be securely and airtight. It can be fixed to the side wall.

Example 2

[0029] Example 2 of the present invention will be described.

As shown in FIG. 7, the aseptic tent of Example 2 is one in which a column member 1 is first formed separately, and a wall sheet is attached thereto so as to be integrated.

[0030] Specifically, a support member-forming mandrel assembly 7 formed by combining a plurality of mandrels is prepared, and two types of long sheets (strips) 201 and 202 similar to those in Example 1 are prepared. The mandrel assemblies 7 are arranged so as to sandwich the corresponding positions, and the hatched portions 106 are welded as shown in FIG. Next, first pull out the mandrels 71, 72, 73, 74 to secure the outlets for the remaining mandrenoles 75, 76, 77, 78, 79, 710, and then in the next step, as shown in FIG. Pull out these remaining mandrels and finally connect the shaded parts 107, 108, 109, 1010, 1011 including the re-welded part to the connectors 81, 82, 83, 82, 81 and air in the shape corresponding to the strut elements of each part. If the injection member XX is attached and welded, the support member 1 can be formed.

[0031] This is formed in advance by forming a strut member, which is the skeleton of the tent, and attaching the tent main body sheet 2 thereto, so that the strut member 1 itself is formed as in Example 1. Workability is worse. Since the strut element is formed with a pair of long member forces, the strut member expands the welding surface symmetrically and evenly. Further, since the hand mounting portion 4 and the assistant hand mounting portion can be formed in advance, the overall workability is the same as that of the first embodiment.
