Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a device for stopping bleeding from soft tissue lacerations during childbirth. Background Technology
[0002] The soft birth canal refers to the part of the female reproductive organs through which the fetus passes during childbirth. It is a curved canal formed by the lower segment of the uterus, the cervix, the vagina, and the soft tissues of the pelvic floor, and is the necessary passage for the fetus to be delivered.
[0003] In obstetric and gynecological surgeries, gauze compression is frequently used for cases where suturing is difficult or fails to stop bleeding. This applies pressure to the bleeding point and directly compresses the severed blood vessel ends, reducing blood leakage. Gauze hemostasis requires experienced personnel and the amount of gauze used must be recorded to prevent gauze from remaining in the uterus. If the packing is not tight, blood may accumulate in the gaps between the gauze. While cost-effective, it carries certain risks. Currently, hemostatic balloons are more expensive but their use is becoming increasingly widespread. After childbirth, women often experience postpartum hemorrhage, retained placental tissue bleeding, bleeding from birth canal lacerations, or bleeding due to uterine insufficiency. When the balloon is empty, it is inserted into the uterus, and saline is injected into the balloon using a syringe. The balloon expands, filling the uterine cavity and compressing the blood vessels at the uterine wound site. Simultaneously, the balloon stimulates the uterus to produce endogenous prostaglandins, inducing uterine contractions and thus achieving hemostasis.
[0004] However, existing hemostatic balloons primarily compress the uterine cavity, with limited effectiveness in compressing the lower uterine segment. Furthermore, they are prone to dislodgement after vaginal delivery or in cases of failed vaginal labor followed by a cesarean section, failing to achieve hemostasis on the cervix and vaginal wall. This poses certain risks and discomfort to the mother. Utility Model Content

[0032] This utility model provides a technical solution: a hemostatic device for soft tissue lacerations, which includes a sac assembly and a catheter assembly. The sac assembly includes a first sac 1 for compressing the cervix and a second sac 2 for compressing the vaginal wall. The first sac 1 is positioned above the second sac 2. The catheter assembly includes a first catheter 3 and a second catheter 4. One end of the first catheter 3 passes through the second sac 2 and communicates with the first sac 1. The other end of the first catheter 3 is connected to one end of the second catheter 4 through a connector 6. The other end of the second catheter 4 is used for filling or releasing liquid. The first catheter 3 has several through holes 5. The connector 6 also has an air inlet 7.
[0033] Specifically, compared to traditional hemostatic balloons, this hemostatic device also features a second balloon 2, positioned below the first balloon 1. When inserted into the vagina, the first balloon 1 is positioned at the cervix, while the second balloon 2 is positioned at the vaginal wall. Depending on the application, the first balloon 1 and the second balloon 2 can be inflated via the first catheter 3 to compress the corresponding areas. Alternatively, they can be inflated with fluid, such as saline, via the second catheter 2. During inflation or inflation, the through-hole 5 facilitates the entry of gas or liquid into the second balloon 2. Therefore, compared to traditional hemostatic balloons that only compress the cervix, this hemostatic device can simultaneously compress both the cervix and the vaginal wall, achieving better hemostasis. Furthermore, the amount of fluid inflated can be adjusted according to the specific situation, greatly improving flexibility.
[0034] As an optional implementation, in some embodiments, the second capsule 2 is further provided with several straps 8 near the end of the connector 6. When the hemostatic device is placed inside the patient's vagina, the end of the second capsule 2 is at the vaginal opening. At this time, the straps 8 are crossed and wrapped around the thigh for fixation, which can improve the stability of the device. At the same time, it can also exert an upward pressure to prevent the second capsule 2 from accidentally dislodging from the vagina.
[0035] In the above embodiment, furthermore, each end of the plurality of straps 8 is provided with a matching male Velcro 9 and a female Velcro 10. Using Velcro to secure the straps 8 improves convenience.
[0036] As an optional implementation, in some embodiments, a first valve 11 is also provided near the inflation port 7. The first valve 11 allows medical personnel to more precisely control the amount of gas injected into the bladder assembly, achieving optimal hemostasis based on different patients' conditions and needs. Simultaneously, closing the first valve 11 maintains stable gas pressure in the bladder assembly, preventing gas leakage and ensuring the persistence of the hemostatic effect. Furthermore, the first valve 11 makes inflation and deflation operations more convenient for medical personnel, improving work efficiency.
[0037] As an optional implementation, in some embodiments, the connector 6 is also provided with a drainage port 12. The drainage port 12 is used to connect a drainage bag. By draining the blood accumulated in the uterine cavity, the bleeding from the wound can be cleared in a timely manner, avoiding local blood stasis that could lead to hematoma, promoting tissue repair, and reducing the pressure of the hematoma on surrounding tissues, thus reducing secondary damage caused by ischemia.
[0038] As an optional implementation, in some embodiments, the first sac 1 is hemispherical in shape. This shape better matches the shape of the cervix, allowing for better compression of the cervix and thus achieving a better compression effect.
[0039] As an optional implementation, in some embodiments, the second capsule 2 is cylindrical in shape. This shape better matches the shape of the vaginal wall, allowing for better compression of the vaginal wall and thus achieving a better compression effect.
[0040] As an optional implementation, in some embodiments, the second catheter 4 is Y-shaped, having a first port 13, a second port 14, and a third port 15 that are interconnected. The first port 13 is connected to the connector 6, the second port 14 is used for filling with liquid, and the third port 15 is used for draining with liquid. The Y-shaped catheter has an extra port compared to a regular catheter, allowing connection to different devices to achieve the effect of filling and draining liquid into the capsule assembly, thus improving convenience.
[0041] As an optional implementation, in some embodiments, a second valve 16 is provided on the second conduit 4 near the second port 14, and a third valve 17 is provided on the second conduit 4 near the third port 15. Similar to the effect of installing the first valve 11 described above, installing the second valve 16 and the third valve 17 facilitates the filling and emptying of fluids by medical personnel, and will not be elaborated further here.
[0042] As an optional implementation, in some embodiments, the first capsule 1 and the second capsule 2 are made of medical-grade silicone. Medical-grade silicone has good biocompatibility, and after implantation, it will not cause foreign body reactions or inflammation, ensuring patient safety and comfort. It is non-toxic, odorless, environmentally friendly, and healthy; even with prolonged contact with the human body, it will not release any harmful substances. Furthermore, it maintains its original elasticity and softness during contact with bodily fluids and tissues and is not easily degraded. This allows the capsules to maintain stable shape and performance during hemostasis.
