Description

Technical Field

[0001] The utility model belongs to the field of medical technology and relates to a sterile area isolation system. Background Art

[0002] In the operating room, doctors may need to leave for a short period of time for a variety of urgent or scheduled situations. These situations may include dealing with complications from another operation, coordinating multiple operations, necessary communication with patients and their families, participating in emergency meetings, or performing necessary medical procedures. Although these activities are critical, they can interrupt the surgical flow and put the sterile environment in the operating room at risk.

[0003] When the doctor leaves, the surgical field may be exposed to multiple risks. The most important is potential microbial contamination, which may come from airborne particles, personnel movement, unsealed surgical instrument trays, etc. In addition, any removal or interruption of the sterile barrier may lead to cross-infection, increasing the risk of postoperative infection for patients.

[0004] To reduce these risks, hospitals have taken a number of steps to maintain the sterility of surgical areas and instruments. One of these steps is to use disposable sterile drapes to cover surgical instruments and areas to prevent contamination.

[0005] At present, the most commonly used disposable sterile non-woven fabrics or plastic films in hospitals are used to directly cover surgical instruments. When the operation needs to continue, the covering sterile non-woven fabrics or plastic films are directly removed or opened. At this time, dust, bacteria, etc. are inevitably retained on the non-woven fabrics or plastic films that have been covered for a long time, and microorganisms are attached. These pollutants are easily scattered when the covering is removed, thereby contaminating the sterile instruments below. Summary of the invention

[0006] The utility model proposes a sterile area isolation system in view of the problems existing in the prior art, aiming to overcome the defect that bacteria, dust and the like on the existing disposable sterile non-woven fabric or plastic film are easily scattered on the instrument when the non-woven fabric or plastic film is opened.

[0007] The utility model is achieved in this way:

[0008] A sterile area isolation system, characterized in that it includes a first covering member and a second covering member, the first covering member has a first isolation portion, the second covering member has a second isolation portion, the first isolation portion and the second isolation portion overlap to form a cross isolation area, the first covering member and the second covering member are bonded at an overlapping position, and the first covering member and the second covering member both have handles.

[0009] Preferably, the first cover comprises a first single-layer cover connected to the first end of the first isolating part, the second cover comprises a second single-layer cover connected to the first end of the second isolating part and a folding part connected to the second end of the second isolating part, and the handle on the second cover is fixed to the folding part. The folding part facilitates the process of separating the first cover and the second cover, so that the lower surface of the second isolating part is turned up, thereby reducing the risk of bacteria, dust, etc. on the upper surface of the second cover falling onto the instrument.

[0010] Preferably, a single-sided adhesive strip is attached to the upper surface of the first isolation part along its length, and a double-sided adhesive strip with an isolation function is attached to the lower surface of the second isolation part along its length, and the double-sided adhesive strip is bonded and fixed to the single-sided adhesive strip. The double-sided adhesive strip and the single-sided adhesive strip are conducive to the separation of the two, avoiding the need for excessive force to separate the first cover and the second cover, resulting in bacteria, dust and other pollutants being shaken off and contaminating the underlying equipment.

[0011] Preferably, the first covering member comprises a transparent segment and a non-woven fabric segment, and the first isolation portion is located on the transparent segment.

[0012] Preferably, the second cover comprises a transparent section and a non-woven fabric section, and the second isolation portion is located on the transparent section. The first cover and the second cover both have transparent sections, so that a transparent area is formed in the middle of the isolation system, which is convenient for the operator to observe the shape of the instrument and to fine-tune the force application speed and direction.

[0013] Preferably, the non-woven fabric segment is made of polypropylene non-woven fabric or spunlace non-woven fabric, and the transparent segment is made of polyethylene film or TPU film.

[0014] Preferably, the non-woven fabric segment and the transparent segment are bonded by double-sided adhesive, hot-melt adhesive or cold adhesive;

[0015] Alternatively, the non-woven fabric segment and the transparent segment are ultrasonically welded;

[0016] Alternatively, the nonwoven fabric segment and the transparent segment are connected by seams.

[0017] Preferably, both the first cover piece and the second cover piece are provided with indication labels to indicate the correct direction in which the handle should be pulled.

[0018] The sterile area isolation system provided by the utility model is formed by partially overlapping two covering parts to form a cross isolation area. Dust will not fall onto the upper surface of the first isolation part and the lower surface of the second isolation part. When the isolation system needs to be removed, the two covering parts are disconnected at the bonding point by a handle. There is no dust at the separation position of the two covering parts, which ensures that the instruments under the isolation system will not be contaminated by foreign matter such as dust.

DETAILED DESCRIPTION

[0023] The following will further describe the specific implementation of the utility model in combination with the accompanying drawings of the embodiments, so that the technical solution of the utility model is easier to understand and grasp. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0024] This embodiment provides a sterile area isolation system, such as Figure 1-3 As shown, it includes a first cover 100 and a second cover 200, the first cover 100 has a first isolation part 110, the second cover 200 has a second isolation part 210, the first isolation part 110 and the second isolation part 210 overlap to form a cross isolation area, the first cover 100 and the second cover 200 are bonded at the overlapping position, and the first cover 100 and the second cover 200 both have a handle 300. The second isolation part 210 covers the first isolation part 110, so the upper surface of the first isolation part 110 and the lower surface of the second isolation part 210 are in an isolated state, and pollutants such as bacteria and dust from the outside are not easy to contact the upper surface of the first isolation part 110 and the lower surface of the second isolation part 210. When it is necessary to remove the isolation system, pull the handle 300 to separate the first cover 100 and the second cover 200 at the bonding point, and the gap parts during the separation process correspond to the first isolation part 110 and the second isolation part 210, wherein the upper surface of the first isolation part 110 is in a sterile state, and the lower surface of the second isolation part 210 is turned up, and the dust-free side of the second isolation part 210 is also facing up, thereby ensuring that no bacteria, dust and other pollutants will fall from the separation gap and contaminate the equipment below.

[0025] like Figure 1 , 3As shown, the first cover 100 includes a first single-layer cover connected to the first end of the first isolation part 110, the second cover 200 includes a second single-layer cover connected to the first end of the second isolation part 210 and a folding part 220 connected to the second end of the second isolation part 210, and the handle 300 on the second cover 200 is fixed on the folding part 220. The folding part 220 facilitates the turning up of the lower surface of the second isolation part 210, so that the operation of the lower surface of the second isolation part 210 facing upward is more convenient during the separation process of the first cover 100 and the second cover 200.

[0026] like Figure 1 As shown, a single-sided adhesive strip 111 is attached to the upper surface of the first isolation part 110 along its length direction, and a double-sided adhesive strip 211 with an isolation function is attached to the lower surface of the second isolation part 210 along its length direction, and the double-sided adhesive strip 211 is bonded and fixed to the single-sided adhesive strip 111. In the process of separating the first cover 100 and the second cover 200, the double-sided adhesive strip 211 and the single-sided adhesive strip 111 are separated, so that the first cover 100 and the second cover 200 can be separated from each other. In other optional embodiments, the single-sided adhesive strip 111 may not be provided, and only the double-sided adhesive strip 211 may be provided.

[0027] like Figure 1-3 As shown, the first cover 100 includes a transparent section 410 and a non-woven fabric section 420, and the first isolation portion 110 is located on the transparent section 410. The second cover 200 includes a transparent section 410 and a non-woven fabric section 420, and the second isolation portion 210 is located on the transparent section 410. In this way, a transparent visual window is formed in the middle of the isolation system, which is beneficial for the operator to fine-tune the direction and speed of the separation force according to the shape of the underlying instrument. The non-woven fabric material can droop better, which is beneficial for the isolation system to better cover the relevant instruments. In other optional embodiments, the first cover 100 and the second cover 200 can also be a single non-woven fabric material or a single transparent material.

[0028] The non-woven fabric segment 420 is made of polypropylene non-woven fabric. In other optional embodiments, the non-woven fabric segment 420 may also be made of spunlace non-woven fabric.

[0029] The transparent section 410 is made of a polyethylene film. In other optional embodiments, the transparent section 410 may also be made of a TPU film.

[0030] The non-woven fabric section 420 and the transparent section 410 are bonded by double-sided adhesive. In other optional embodiments, the non-woven fabric section 420 and the transparent section 410 may also be bonded by hot melt adhesive or cold adhesive; or, the non-woven fabric section 420 and the transparent section 410 are ultrasonically welded; or, the non-woven fabric section 420 and the transparent section 410 are connected by seams.

[0031] Furthermore, both the first cover member 100 and the second cover member 200 are provided with indication labels 411 to indicate the correct direction of pulling the handle 300 .
