Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a disposable bronchoscope protective device. Background Technology

[0002] A bronchoscope is a medical device inserted through the mouth or nose into the trachea to perform visual examinations, specimen collection, and clearing of secretions from the trachea and bronchi at all levels within the lungs. When using a bronchoscope for examinations or treatments, a series of protective measures must be taken to prevent contamination of the bronchoscope with external microorganisms, thus avoiding the introduction of these microorganisms into the lungs and causing infection. This is especially important for patients in intensive care units who are intubated and on ventilators, as their immunity is low and the bronchoscope is used frequently. Simultaneously, medical staff must also prevent infection from droplets expelled by coughs from patients with infectious diseases.

[0003] Traditionally, when performing bronchoscopy on patients requiring endotracheal intubation and mechanical ventilation, protective measures mainly rely on medical staff wearing sterile surgical gowns, sterile gloves, and using aseptic techniques. Medical staff's self-protection measures mainly include wearing masks, caps, and protective goggles or face shields. However, these measures have certain drawbacks. There is a risk of contamination due to misoperation during the wearing of sterile gloves and surgical gowns, as well as during the use of the bronchoscope, and due to sudden coughing by the patient. Furthermore, the preparation stage for protective measures is cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide a disposable bronchoscopy protective device to simplify the preparation steps for medical personnel's protective measures and avoid contamination.

[0005] To achieve the above objectives, this utility model provides a disposable bronchoscope protective device, which includes a three-way tube, a connecting tube, a fixing tube, and a sealing bag. The fixing tube connects the connecting tube and the sealing bag. The three-way tube is connected to the connecting tube. One end of the sealing bag has an opening, and a drawstring is provided on the opening. The drawstring can be tightened to close the opening.

[0006] The drawstring can be tightened to close the opening and placed on the bronchoscope. During bronchoscope insertion, the sealed bag with a closed design provides a relatively enclosed environment. The opening of the sealed bag allows the external bronchoscope to enter. The drawstring can close the opening, further tightening the bronchoscope after insertion. This ensures a relatively closed environment throughout the bronchoscope use on intubated patients, reducing the possibility of contact with the outside world, increasing the tolerance for contamination-free operation, and effectively reducing the risk of cross-infection. It simplifies protective measures, eliminating the need for medical personnel to wear sterile surgical gowns, effectively saving social resources. Furthermore, the three-way valve connects to the ventilator, and the internal pressure of the entire protective device remains higher than atmospheric pressure. The unsealed portion of the relatively sealed protective device is always in a ventilated state to prevent pathogens from the outside air from entering the protective device.

[0007] Furthermore, the opening is skirt-shaped, and the skirt of the opening has slits.

[0008] The skirt-like design incorporates an incision that allows the bronchoscope to adapt to its bottom structure during insertion, exposing the protruding operating channels on the bronchoscope body. Simultaneously, the incision facilitates the suspension of the garter strap on the bronchoscope. Specifically, the protruding operating channels on the bronchoscope body provide a fulcrum for the garter strap to prevent the sealing bag from sliding downwards, thus improving the relative sealing of the entire protective device. While the incision cannot completely seal against the bronchoscope's operating channels, it can control the airflow direction. Medical personnel can adjust the incision's orientation to prevent droplet transmission.

[0009] Furthermore, the transition between the opening and the sealing bag is provided with an auxiliary strip, which tightens the transition to fit snugly against the outer wall of the bronchoscope.

[0010] After the bronchoscope is inserted, the auxiliary strap, which can be medical tape, is wrapped around the outer edge of the sealing bag, so that the wrapped part of the sealing bag is tightly against the bronchoscope, thereby sealing the airflow channel between the bronchoscope and the sealing bag. This reduces the airflow exhaled by the patient, which flows sequentially through the three-way tube, the connecting tube, the fixing tube, and the sealing bag body, and finally exits from the incision. This reduces the risk of droplet transmission caused by the patient. For medical personnel, the auxiliary strap seals the airflow channel. Even if some airflow penetrates the seal of the auxiliary strap, medical personnel can adjust the direction of the overflowing exhaled air in conjunction with the aforementioned incision, directing it away from the medical personnel. The foregoing description of the use of the auxiliary strap should not be construed as a limitation on the auxiliary strap. Other materials can also be used for the auxiliary strap, such as deformable rubber rings, deformable metal strips, flexible ropes, etc., any material that allows the sealing bag to be tightened and adhered to the bronchoscope.

[0011] Furthermore, the fixing tube includes a connecting tube end and an inlet end, the connecting tube end being connected to the connecting tube, and the inlet end being used to insert the bronchoscope.

[0012] The connecting tube end is connected to the connecting tube, and the inlet end is used to provide an entry path for inserting the bronchoscope.

[0013] Furthermore, a fixing sleeve is provided outside the fixing tube, and an annular buckle and a bevel buckle are provided inside the fixing sleeve. Both the bevel buckle and the annular buckle are snapped together with the fixing tube to lock the sealing bag in place.

[0014] The fixing sleeve is provided outside the fixing tube. The fixing sleeve is used to restrict the sealing bag. The fixing sleeve seals and fixes the end of the sealing bag away from the opening. The fixing sleeve can also be integrally formed with the sealing bag. The annular buckle and the inclined buckle are connected to the fixing tube. The connection method can also be adhesive bonding or buckle connection to achieve the limitation of the sealing bag.

[0015] Furthermore, the connecting pipe is provided with a tee pipe end and a fixed pipe end, the fixed pipe end is connected to the fixed pipe, the fixed pipe end is detachably connected to the fixed pipe, and the tee pipe end is detachably connected to the tee pipe.

[0016] The inner ring of the tee pipe end is threaded.

[0017] The inner ring of the tee pipe end is threaded to achieve the connection and fixation of the tee pipe, and the fixing pipe end is used to connect to the fixing pipe. It can be understood that the tee pipe end and the tee pipe can be connected in a detachable manner by means of snap-fit, adhesive bonding, threaded connection, etc.

[0018] Furthermore, the three-way tube is provided with a connecting tube port, a ventilator port, and an endotracheal tube port. The connecting tube port is connected to the connecting tube, the ventilator port is connected to an external ventilator, and the endotracheal tube port is connected to an endotracheal tube.

[0019] The connecting tube port and the endotracheal tube port form a channel for the bronchoscope to enter, while the ventilator port is connected to an external ventilator to assist the patient's breathing.

[0020] Furthermore, a one-way airflow valve is provided inside the three-way pipe, and the one-way airflow valve is located on the port of the connecting pipe;

[0021] The one-way airflow valve includes a base and a valve body. The base is sleeved on the port of the connecting pipe, and the valve body is located in the middle of the base. The valve body has two deformable inclined surfaces, which are fitted together to form a closed entry channel under normal conditions.

[0022] The one-way airflow valve is closed under natural conditions. When there is ventilator airflow pressure, the airflow pressure acts on the two protruding inclined surfaces inside the one-way airflow valve, generating inward pressure, making the one-way airflow valve close more tightly. This ensures that when the bronchoscope needs to be removed and the connection between the fixing tube and the connecting tube needs to be disconnected during use, the ventilator airflow will not leak out. When using the bronchoscope, the bronchoscope tube can be pushed open from the bottom of the one-way airflow valve to enter the trachea. The entry channel will be closed around the bronchoscope body under the action of airflow, controlling the flow of pressurized gas from the ventilator or exhaled gas from the patient to the sealing bag and preventing leakage.

[0023] Furthermore, the edges of the tee, the connecting pipe, the fixing pipe, and the sealing bag are all designed with rounded edges.

[0024] The edges are rounded to reduce the risk of sharp edges compromising the sealing performance of the bag and to prevent damage to the protective equipment of medical personnel.

[0025] This invention relates to a disposable bronchoscope protective device. The sealed bag has an opening at one end, and a drawstring is provided to tighten the opening. Simultaneously, a three-way tube, a connecting tube, and a fixing tube are provided, all in a sealed state and interconnected. During bronchoscope use, the entire protective device provides a relatively sealed space with an internal air pressure higher than the outside atmosphere, thereby reducing the risk of patient contact with outside air and avoiding potential contamination risks during bronchoscope use. It also reduces the protective burden on medical personnel, simplifying the preparation steps for medical protective measures, increasing the tolerance for contamination-free operation, and preventing contamination.

[0033] The present invention will be further described in detail below with reference to experimental examples and specific embodiments. However, this should not be construed as limiting the scope of the above-mentioned subject matter of the present invention to the following embodiments. All technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0034] This utility model discloses a disposable bronchoscope protective device, including a three-way tube 1, a connecting tube 2, a fixing tube 3, and a sealing bag 4. The fixing tube 3 connects the connecting tube 2 and the sealing bag 4. The three-way tube 1 is connected to the connecting tube 2. One end of the sealing bag 4 is provided with an opening 6, and a drawstring 5 is provided on the opening 6. The drawstring 5 can be gathered to tighten the opening 6.

[0035] The opening 6 is skirt-shaped, and the skirt of the opening 6 has a slit 7.

[0036] The transition between the opening 6 and the sealing bag 4 is also provided with an auxiliary strip 23, which tightens the transition to fit snugly against the outer wall of the bronchoscope.

[0037] Please see Figure 1 and Figure 2In this embodiment, the drawstring 5 is threaded through the sealing bag 4. By tightening the drawstring 5, the tightness of the fit between the bronchoscope and the opening 6 is improved. The drawstring 5 can also be used to suspend and fix the bronchoscope above the protruding control channel. The cut 7 is V-shaped to accommodate different types of bronchoscopes. Alternatively, the drawstring 5 can be integrally formed from an elastic material, allowing it to suspend the bronchoscope after the opening 6 is aligned with it. The drawstring 5 can also be broken at the cut 7 and knotted to secure it to the bronchoscope. It should be noted that in addition to the drawstring 5 tightening the sealing bag 4, an auxiliary strip 23 can also be wrapped around the outside of the sealing bag 4 to further improve the sealing performance between the sealing bag 4 and different types of bronchoscopes.

[0038] Furthermore, the fixing tube 3 includes a connecting tube end 8 and an inlet end 9, the connecting tube end 8 being connected to the connecting tube 2, and the inlet end 9 being used to insert the bronchoscope.

[0039] A fixing sleeve 10 is also provided outside the fixing tube 3. The fixing sleeve 10 is provided with an annular buckle 11 and a beveled buckle 12. The beveled buckle 12 and the annular buckle 11 are both snapped together with the fixing tube 3 to lock the sealing bag 4 in place.

[0040] Please see Figure 2 and Figure 3 In this embodiment, the connecting tube end 8 is connected to the connecting tube 2, and the fixing tube 3 is detachably connected to the connecting tube 2. When the bronchoscope becomes blocked or the imaging is unclear, and it needs to be withdrawn, it does not need to be withdrawn from the sealing bag 4. Instead, the front end of the bronchoscope is withdrawn into the fixing tube 3, and the connection between the connecting tube end 8 and the connecting tube 2 is disconnected, which allows for rinsing and wiping. The inlet end 9 restricts the entry path of the bronchoscope after it is inserted. The fixing sleeve 10 is used to engage and restrict the end of the sealing bag 4 away from the opening 6. The inclined buckle 12 and the annular buckle 11 improve the connection stability between the fixing sleeve 10 and the fixing tube 3, while restricting the sealing bag 4 between the inclined buckle 12 and the annular buckle 11.

[0041] Furthermore, the connecting pipe 2 is provided with a tee pipe end 13 and a fixed pipe end 14. The fixed pipe end 14 is connected to the fixed pipe 3, and the fixed pipe end 14 is detachably connected to the fixed pipe 3. The tee pipe end 13 is detachably connected to the tee pipe 1.

[0042] The inner ring of the tee end 13 is provided with a thread 15.

[0043] Please see Figure 3 In this embodiment, the tee end 13 is used to connect to the tee pipe 1, and the fixed end 14 connects to the fixed pipe 3. The inner ring of the tee end 13 is provided with the thread 15 to improve the connection stability between the tee end 13 and the tee pipe 1. The thread 15 can be used to connect the tee end 13 and the tee pipe 1, or it can be used to achieve a stable connection and fixation by gluing or snap-fitting.

[0044] Furthermore, the three-way tube 1 is provided with a connecting tube port 16, a ventilator port 17 and an endotracheal tube port 18. The connecting tube port 16 is connected to the connecting tube 2, the ventilator port 17 is connected to an external ventilator, and the endotracheal tube port 18 is connected to an endotracheal tube.

[0045] The three-way pipe 1 is provided with a one-way airflow valve 19, which is located on the connecting pipe port 16.

[0046] The one-way airflow valve 19 includes a base 20 and a valve body 21. The base 20 is sleeved on the connecting pipe port 16. The valve body 21 is located in the middle of the base 20, and the valve body 21 is provided with two deformable inclined surfaces 22. The two inclined surfaces 22 are attached to each other to form a closed entry channel under normal conditions.

[0047] Please see Figures 3-5 In this embodiment, the one-way airflow valve 19 is made of soft plastic material. The outer edge of the base 20 is fitted onto the connecting pipe port 16 of the three-way pipe 1. The valve body 21 in the middle of the base 20 points towards the three-way pipe 1. In its natural state, the one-way airflow valve 19 is closed. When there is ventilator airflow pressure, the airflow pressure acts on the two inclined surfaces 22 of the valve body 21, generating inward pressure, making the one-way airflow valve 19 close more tightly. This controls and prevents ventilator airflow leakage when the bronchoscope is withdrawn and the fixing tube 3 is disconnected from the connecting pipe 2. When using the bronchoscope, the bronchoscope tube can be opened from the one-way... The airflow valve 19 is opened at the bottom and enters the trachea. The outer side of the connecting pipe port 16 can be threaded to connect to the three-way pipe end 13, thereby fixing the one-way airflow valve 19 between the connecting pipe port 16 and the three-way pipe end 13. That is, the setting of the one-way airflow valve 19 can reduce the amount of exhaled gas from the patient and reduce the protective pressure on medical staff. It should be noted that the connection method between the connecting pipe port 16 and the three-way pipe end 13 is not limited to threaded connection. Such as snap-fit, adhesive bonding, and melting are also acceptable. The schematic form in the drawings of the specification should not be construed as a limitation on the connection method of this utility model.

[0048] Furthermore, the edges of the three-way pipe 1, the connecting pipe 2, the fixing pipe 3, and the sealing bag 4 are all designed with rounded edges.

[0049] In this embodiment, a rounded design is used to avoid damaging the sealed bag 4 and injuring the protective equipment of medical personnel.

[0050] This utility model discloses a disposable bronchoscope protective device. When needed, the bronchoscope is inserted through the opening 6, the incision 7 is aligned with the exposed bronchoscope's protruding operating channel, and then the tightening strap 5 is used to seal the opening 6 and the bronchoscope. After insertion, the auxiliary strap 23 is wrapped around and fixed to the sealing bag 4 to form a relative seal. This allows the patient to avoid external contamination within the sealed environment of the sealing bag 4, and also reduces the amount of exhaled air from the patient, thus reducing the protective burden on medical staff. Simultaneously, a one-way airflow valve 19 is installed inside the three-way tube 1 to facilitate bronchoscope retraction. The aforementioned one-way airflow valve 19 can close the inlet channel under the action of pressurized gas or in a natural state. When the connecting pipe 2 and the fixed pipe 3 are disconnected, the leakage of airflow from the patient can be controlled, which can reduce the protective burden on medical personnel. The protective device proposed in this utility model addresses the problem of cumbersome preparation steps for medical personnel during the use of bronchoscopes in the prior art. The technical solution of this utility model can not only provide a relatively sealed space for the bronchoscope, reducing the protective pressure on medical personnel, but also prevent the bronchoscope from being contaminated by external air and infecting patients.

[0051] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
