Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to a clinical obstetric protective device. Background Technology

[0002] During obstetric surgery and delivery, medical staff often face the risk of facial contamination from splashes of amniotic fluid, blood, and other bodily fluids. Wearing facial protective devices is an important measure to ensure the occupational safety of medical staff. Currently, obstetric facial protective devices typically include a headband and a transparent face shield fixed to the front of the headband. Some protective devices also have a collection tank or recovery strip at the bottom of the face shield to collect liquids that flow down the surface of the face shield, preventing bodily fluids from dripping onto the neck or surgical gown.

[0003] However, existing obstetric protective devices still have the following shortcomings: the mask surface lacks hydrophobic treatment, and splashed bodily fluids easily adhere to the mask to form a water film or mist, affecting the clarity of the operator's field of vision; the absorbent material in the collection tank is not firmly fixed and is prone to displacement or detachment during use, affecting the reliability of collection; the headbands are mostly of fixed size or have a limited range of adjustment, making it difficult to adapt to operators with different head circumferences, resulting in poor wearing comfort and stability; and the mask lacks lateral flow-blocking structures on both sides, allowing liquid to easily flow out from the edges and contaminate the operator's neck or shoulders.

[0004] To address these issues, we provide a clinical obstetric protective device. Summary of the Invention

[0005] The purpose of this invention is to provide a clinical obstetric protective device. By combining the headband with the child and mother Velcro straps, the problem of inconvenient wearing and adjustment is solved. By combining the liquid storage structure with the mask, the problems of body fluid obstructing vision and poor collection reliability are solved. By setting the water-blocking strip, the problem of liquid easily flowing out from the side edge is solved.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution.

[0007] This invention relates to a clinical obstetric protective device, comprising a headband and a liquid storage structure. A sub-Velcro strap is provided on the outer left side of the headband, and a master Velcro strap is provided on the inner left side of the headband. A face mask is fixedly connected to the front of the bottom of the headband. The liquid storage structure is used in conjunction with the face mask to collect liquid splashed onto the face mask.

[0008] The present invention is further configured such that the liquid storage structure includes a liquid storage strip, the top of the liquid storage strip has a groove, and the inner cavity of the groove is movably connected to an absorbent strip.

[0009] The present invention is further configured such that a locking block is fixedly connected to the top right side of the absorbent strip, and the inner cavity of the locking block engages with the liquid storage strip.

[0010] The present invention is further configured such that a limiting groove is provided at the top and bottom of the front right side of the liquid storage strip, and a limiting block is engaged in the inner cavity of the limiting groove. The side of the limiting block near the inner wall of the block is fixedly connected to the inner wall of the block.

[0011] The invention is further configured such that the card block is supported by an elastic material, and a lever is fixedly connected to the bottom of the front side of the card block.

[0012] The invention is further configured such that the length of the sub-Velcro strap extends to the left edge of the mask, and the length of the mother Velcro strap extends to the right edge of the mask.

[0013] The present invention is further configured such that the material of the face mask is polycarbonate, and the surface of the face mask is coated with a hydrophobic coating, the hydrophobic coating being a fluorinated polymer.

[0014] The present invention is further configured such that water-blocking strips are fixedly connected to both sides of the face mask, and the material of the water-blocking strips is the same as that of the face mask.

[0015] The present invention has the following beneficial effects.

[0016] 1. This invention allows for flexible adjustment of tightness according to different head circumferences through the combination of the headband, the secondary Velcro strap, and the primary Velcro strap, ensuring a secure and comfortable fit. The liquid storage structure, when used with the mask, effectively collects bodily fluids splashed onto the mask surface, preventing liquid from dripping down the lower edge of the mask and contaminating the operator. The overall structure is simple, easy to wear, and suitable for quick use during obstetric surgery.

[0017] 2. The mask of this invention is made of polycarbonate material, which has high transparency and strong impact resistance. The surface is coated with a hydrophobic coating of fluorinated polymer, which causes body fluids to condense into water droplets and roll off quickly, effectively preventing fogging and maintaining a clear field of vision for a long time. The groove at the top of the liquid storage strip and the absorbent strip work together to form a dual collection mechanism of guiding and adsorption. The absorbent strip is positioned by snapping with the liquid storage strip through a locking block, which is convenient to install and remove, and is fixed reliably. It can be replaced at any time to ensure the absorption effect. The bidirectional limiting groove and the limiting block further enhance the connection stability. The lever is easy to operate with one hand. The water-blocking strips on both sides of the mask guide the liquid to converge in the middle, forming an all-round anti-leakage system in conjunction with the liquid storage structure.

[0021] The technical solutions of the present invention will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present invention, and not all embodiments. Example 1

[0022] Please see Figure 1-4 The present invention is a clinical obstetric protective device, including a headband 1 and a liquid storage structure 5. A sub-V-band 2 is provided on the outer left side of the headband 1, and a mother V-band 3 is provided on the inner left side of the headband 1. A face mask 4 is fixedly connected to the front of the bottom of the headband 1. The liquid storage structure 5 is used in conjunction with the face mask 4 to collect liquid splashed onto the face mask 4.

[0023] The headband 1, together with the child magic band 2 and the mother magic band 3, allows for flexible adjustment of tightness according to different head circumferences. It is secure, comfortable, and highly adaptable. The liquid storage structure 5, used in conjunction with the mask 4, can effectively collect amniotic fluid, blood, and other bodily fluids that splash onto the surface of the mask 4 during childbirth, preventing liquid from dripping down the lower edge of the mask 4 onto the neck or surgical gown, significantly reducing the risk of contamination for medical staff. The overall structure is simple and easy to wear, making it suitable for quick use during obstetric surgery.

[0024] The liquid storage structure 5 includes a liquid storage strip 501, a groove 502 is provided on the top of the liquid storage strip 501, and an absorbent strip 503 is movably connected to the inner cavity of the groove 502.

[0025] By creating a groove 502 at the top of the liquid storage strip 501 and movably connecting an absorbent strip 503 within the groove 502, a dual collection mechanism of physical guidance and capillary adsorption is formed. This mechanism can both intercept liquid flowing down the surface of the mask 4 and quickly absorb and lock the liquid, preventing it from accumulating, shaking, and overflowing. This effectively improves the reliability and safety of the collection. At the same time, the absorbent strip 503 can be replaced at any time to ensure the absorption effect each time it is used, meeting the hygiene requirements for single-use medical applications.

[0026] A locking block 504 is fixedly connected to the top right side of the absorbent strip 503, and the inner cavity of the locking block 504 is engaged with the liquid storage strip 501.

[0027] The absorbent strip 503 is fixedly connected to the top of the locking block 504, which engages with the liquid storage strip 501 to securely position the absorbent strip 503 in the groove 502. This effectively prevents the absorbent strip 503 from shifting or coming out during use due to head shaking or liquid impact, ensuring the continuous effectiveness of the collection function. At the same time, the locking structure can be disassembled and assembled without the aid of tools, making it convenient for medical staff to quickly replace the absorbent strip 503 during surgical breaks, thus improving work efficiency.

[0028] Limiting grooves 505 are provided on the top and bottom of the front right side of the liquid storage strip 501. The inner cavity of the limiting groove 505 is engaged with a limiting block 506. The side of the limiting block 506 near the inner wall of the locking block 504 is fixedly connected to the inner wall of the locking block 504.

[0029] By engaging the limiting groove 505 with the limiting block 506, bidirectional longitudinal and lateral limiting is added to the engagement between the locking block 504 and the liquid storage strip 501. This effectively prevents the locking block 504 from loosening or detaching due to external force or shaking during use, significantly improving the stability and reliability of the connection. At the same time, the limiting structure ensures that the absorbent strip 503 is accurately positioned in the predetermined position within the groove 502 after each installation, avoiding skewing that could affect the liquid collection effect.

[0030] The locking block 504 is supported by an elastic material, and a lever 507 is fixedly connected to the bottom front side of the locking block 504.

[0031] The locking block 504 is made of elastic material and uses its own elastic deformation to achieve locking and unlocking, making operation easy and effortless. The lever 507 fixedly connected to the bottom front side of the locking block 504 provides a clear point of force for the fingers. Medical staff can quickly disassemble and install the absorbent strip 503 by pinching the lever 507 with one hand without the need for additional tools, which greatly improves the efficiency of replacement and the convenience of operation.

[0032] The length of the sub-magic band 2 extends to the left edge of the mask 4, and the length of the mother magic band 3 extends to the right edge of the mask 4.

[0033] By extending the sub-magic strap 2 and the mother magic strap 3 to the left and right edges of the mask 4 respectively, the overall adjustable circumference of the headband 1 covers the head size of most adults, making it more adaptable. The larger adhesive area makes the headband 1 more secure, effectively preventing slippage and loosening during wear, ensuring that the mask 4 is always facing the operator's face, while the pressure distribution is more even, avoiding the feeling of excessive tightness in some areas, and improving the comfort of wearing it for a long time.

[0034] The mask 4 is made of polycarbonate and has a hydrophobic coating on its surface, which is a fluorinated polymer.

[0035] The face mask 4 is made of polycarbonate, which has excellent optical transparency and impact resistance, ensuring clear vision for the operator while effectively protecting against splashes of bodily fluids or accidental collisions. The hydrophobic coating of fluorinated polymer on the surface of the face mask 4 causes bodily fluids to condense into water droplets and roll off quickly, effectively preventing fogging and maintaining clear vision for a long time. At the same time, the hydrophobic coating makes it difficult for contaminants to adhere to the surface of the face mask 4, reducing the potential risk of contact transmission and further improving protective safety.

[0036] Water-blocking strips 6 are fixedly connected to both sides of the mask 4. The material of the water-blocking strips 6 is the same as that of the mask 4.

[0037] By fixing water-blocking strips 6 to both sides of the mask 4, a physical barrier is formed on both sides of the mask 4, effectively guiding the liquid flowing down the surface of the mask 4 to converge into the central liquid storage structure 5, preventing the liquid from flowing out from the side edges of the mask 4 and contaminating the operator's neck or shoulder area. The water-blocking strips 6 and the mask 4 are made of the same material and can be manufactured by an integral molding process without additional bonding or welding, which reduces manufacturing costs and ensures connection strength. The water-blocking strips 6 and the bottom liquid storage structure 5 work together to form a complete leak-proof system at the bottom and sides of the mask 4, making the collection more comprehensive and reliable.

[0038] The working principle of this invention is as follows: During use, medical personnel wrap the headband 1 around their head according to their own head circumference. The tightness is adjusted to a comfortable fit by attaching the sub-Velcro strap 2 to the mother Velcro strap 3. During childbirth, amniotic fluid, blood, and other bodily fluids splashed onto the surface of the mask 4 will flow downwards along the surface of the mask 4 under the action of gravity. Under the action of the hydrophobic coating, the liquid will quickly slide into the groove 502 of the bottom liquid storage strip 501. The absorbent strip 503 in the groove 502 will immediately absorb and lock the liquid to prevent the liquid from accumulating and overflowing. When the liquid on the surface of the mask 4 condenses into water droplets under the action of the hydrophobic coating, it will quickly roll off, keeping the vision of the mask 4 clear at all times. The water-blocking strips 6 on both sides of the mask 4 prevent the liquid from flowing out from the side edges, ensuring that all liquids are guided to the liquid storage structure 5 for collection. After use, the lever 507 is pinched to make the elastic clip 504 disengage from the liquid storage strip 501, and the absorbent strip 503 can be removed and replaced for the next use.
